Comment by Tom Davey
Can tiny `whiskers’devastate hi-tech equipment? ccording to Newton’s second law of motion, there is a reaction to every action. While reducing the undeniably toxic lead from solder seems an intelligent move, environmental problems are reported from the implementation of a European Union move to ban or reduce lead in manufacturing. While tin whiskers, microscopic growths of the metal from soldering points on circuit boards, may seem primitive, fragile things, yet they have left a trail of expensive wreckage amid a surprisingly wide range of hi-tech equipment and industries. On April 17, 2005, the Millstone nuclear plant in Connecticut shut down when a circuit board monitoring a steam pressure line shortcircuited. In 2006, a huge batch of Swatch watches were recalled at an estimated cost of $1bn. In these and many other cases, tin whiskers were blamed. These are not the only times these mysterious growths have caused electronics failures. In 1998 a Galaxy IV communications satellite sputtered out after just five years; engineers diagnosed its failure as due to “whiskers”. The US military also blamed them for malfunctioning F-15 radar systems and misguided Phoenix and Patriot missiles. In 1986 the US Food and Drug Administration recalled a number of pacemakers because of whiskers. One suggested solution to “whiskering” is to add lead into the solder, as was common in the 1950s. Colin Hughes, a physicist who worked on the first British nuclear bomb, notes that whiskering problems never came up during his career. But now, by legal mandate, the lead is gone and a serious problem from whiskers is back – causing havoc in diverse hi-tech industries. Lead has been banned from solder in the European Union since 2006 under a 2003 Reduction of Hazardous Substance (RoHS) di-
rective. This gave manufacturers three years to phase it out. The logic seemed reasonable. Removing lead from gasoline has brought clear environmental and health benefits. Removing it from solder, the 37% lead, 63% tin alloy used to join metal objects in everything from plumbing to circuit boards, seemed the obvious next step to prevent leaching into groundwater from landfills.
But without lead to tame it, tin behaves oddly on circuit boards. Apparently, when left alone, tin plating, such as cadmium and zinc, may spontaneously generate microscopic shreds of metal – about one to five microns in diameter. If they grow far enough to touch another current-carrying location, they may cause circuits to short and then wreck equipment. The cause is becoming clearer. Steve Jones of Circatex, in South Shields, England, says: “I believe the mechanism of whisker formation is now understood: it is due to compressive stress – caused by, say, diffusion of copper into the tin being built up in the tin layer
breaking through the tin oxide barrier layer (to the air).” “I still use lead-tin solder – it works better,” says John Ketterson, a solid state physicist at Northwestern University in Illinois. He notes the trade-offs of ‘cost, materials, strength of the solder and all that’ during a mandated changeover, and that manufacturers ‘have to get an experience base’ with new processes. This means unwitting consumers bear the cost of experimental burdens. So are products the public are using affected by tin whiskers? Many customers dismiss the costs of failed devices as isolated cases while the true culprit could be microscopic whiskers inside their machines. But was it sensible to go leadfree? Earlier obsolescence from equipment which develop whiskers means more discarded devices. Some critics also argue that substitutes are more toxic and energy intensive, or that lead doesn’t leach from circuit boards because it doesn’t migrate as lead in paint or gasoline does. The National Electronics Manufacturing Centre for Excellence, sponsored by the US Navy, did find that modifying the temperatures at which soldered items are stored diminishes whiskering, but nevertheless recommended “the use of lead in conflict with future industrial practice.” After its expensive recall, Swatch gained a permanent exemption from the RoHS directive for its exports to the EU. Perhaps a reliable lead-free soldering process will be conjured up one day, although experts doubt it. Companies such as IBM and National Instruments say they are achieving RoHS-compliant techniques even for exempt products. But this debate among professionals seems to be ongoing.

Ontario’s Chief Drinking Water Inspector releases new report ntario’s Chief Drinking Water Inspector, Keith West, has presented his annual report for April 1, 2006 to March 31, 2007 to Environment Minister John Gerretsen. The report looks at the overall performance of Ontario’s drinking water systems. It has information on the ministry’s inspections of municipal residential drinking water systems and licensed drinking water testing laboratories. It also has information on private systems serving residences, schools, health and social care facilities and children’s camps. Key results for 2006-2007 Some 99.83 per cent of water quality tests submitted by municipal residential drinking water systems met Ontario drinking water standards. Some 99.49 per cent of water quality tests submitted by systems serving designated facilities met Ontario drinking water standards. Over 102,000 microbiological and chemical tests were conducted at these systems. Some 99.40 per cent of water quality tests submitted by non-municipal yearround residential systems met Ontario drinking water standards. These systems serve private subdivisions, condominium or townhouse complexes, apartment buildings, mobile home parks, as well as year round cottage developments and trailer parks. Microbiological and chemical testing Ontario has stringent, health-based standards for microbiological, chemical and radiological contaminants to protect drinking water quality. As bacterial contamination can pose severe health hazards, Ontario has adopted zero tolerance standards. For example, tests for E. coli must demonstrate that their presence is undetectable. Ontario’s standards for chemical contaminants are set at levels where no adverse effects are observed, with an additional margin of safety factored in. Inspections The ministry inspected all 707 municipal residential drinking water systems in the province. Inspectors assessed systems against about 140 regulatory requirements, all tailored to the type of drinking water system being inspected.
The inspection takes into account local factors such as the drinking water source, the type of system and whether the inspection is detailed or focused. The ministry took mandatory action within 14 days of finding a deficiency at a municipal system. It issued 23 orders to 20 municipal residential drinking water systems. An order does not necessarily mean that drinking water is unsafe. Orders are also used to correct situations where there was no direct threat to human health. Examples include the need to improve administrative procedures or to prevent a possible drinking water issue. The ministry inspected all 57 licensed drinking water testing laboratories in Ontario at least twice in 2006-07. About half the inspections were unannounced. Ten of the inspections responded to public complaints or concerns of ministry staff. Rating municipal operations For the second year, the report provides inspection ratings for municipal residential drinking water systems. Inspection ratings are a tool designed to indicate how well the operation of a system is doing against Ontario’s inspection framework. The rating offers a snapshot of a system’s operation at the time of inspection. Overall, the operational performance of municipal residential drinking water systems is very good. The majority, 92 per cent, of inspection ratings were 90 per cent or better. A lower inspection rating does not mean the drinking water from the system is unsafe. It shows areas where the operation of a system can improve. The ministry works with owners and operators of systems that score lower ratings to make sure they know what they need to do to achieve full compliance. The inspection ratings help track yearly progress toward the goal of 100 per cent compliance for all systems in the province. This year the number of municipal residential drinking water systems demonstrating 100 per cent compliance increased by seven per cent over 2005-06. Forty per cent of the ratings were 100 per cent.

The Ottawa Airport expansion â€“ water quality and risk management By Mark Adamaley he recent expansion of the Ottawa Airport entailed the conversion of parking areas into apron areas and the subsequent development of a new storm sewer. As part of these developments, the Ottawa McDonald-Cartier International Airport Authority sought to achieve stormwater quality treatment and emergency risk management, capable of containing any oil or jet fuel spills of up to 30,000 litres to prevent any contamination of local storm sewers or surrounding water bodies. In response to the challenge, Maurice Best, P.Eng., and Roger Quesnel, CET, of Ainley Graham and Associates, considered several solutions before settling on a unique design which involved the application of an Armtec Vortechs Oil Grit Separator and Armtec Motorized Gate Valves. The Vortechs system is a hydrodynamic separator that enhances gravitational separation of target pollutants from stormwater. Stormwater enters the unit at a tangent to a swirl chamber, which generates a gentle swirling motion and causes suspended particles to settle out of solution. Stormwater flows then proceed to the second treatment chamber where oil, grease and floating debris are separated from the water by means of an obstructing baffle wall and the relatively low specific gravity properties of the pollutants. Subsequently, treated stormwater

The unit arrived on the project site in five pre-cast sections, with a total weight of 26,900 kg, and took less than eight hours to be assembled. Subsequently, the remotely operated motorized gate valves were installed at the downstream end of the Vortechs, ensuring that, in the case of a contaminant spill, the valves could be shut and the
spill contained within the unit. The Vortechs system provided several benefits for the construction process. By virtue of the unitâ€™s standard height of 7.2 feet and unique horizontal shape, the excavation profile was relatively shallow and created cost savings for the contractor. In addition, the installation process was relatively easy as the depth of the structure was only 0.9 metres below the pipe invert, compared to the 9.0 metres depth of some other products. Furthermore, the maintenance procedure requires the removal of silt and water from the swirl chamber only and not the entire structure. Therefore, there is less volume for vacuum trucks to remove and, thus, long-term cost savings for the Airport Authority. Mark Adamaley is with Armtec. E-mail: email@example.com

Ontario dairy farmer awarded $1.7 million for groundwater contamination By Marc McAree and Barry Spiegel erendsen v. Ontario1 is a recent and significant decision of the Ontario Superior Court of Justice. It is one illustration of the expanding environmental liability of governments. Courts are finding that governments whose operations cause contamination have a duty to disclose risks and remedy harm, or pay the consequences. On January 18, 2008, the Court ordered the Province to pay compensation of $1.7 million to the Berendsen family for damages arising from asphalt-related contamination of the family’s dairy farm. The action was launched 14 years ago in 1994 and included a challenge to the Berendsens’ right to bring the action that went to the Supreme Court of Canada in 2001. The case arose as a result of actions taken almost four decades ago. In the 1960s, waste concrete and asphalt from highway reconstruction was buried on a farm by an independent contractor hired by the Ontario Ministry of Transportation (MTO). Waste was buried close to a stream running through the property. Although the owner of the farm consented to burial of the waste, he was never informed that it was anything other than inert material. He subsequently sold to a new owner, without bothering to disclose the buried waste. That owner subsequently sold to the Berendsens. The plaintiffs, the Berendsens, were successful dairy farmers in Europe. They moved to Ontario and purchased the farm in 1981. At the time of purchase, they were not informed about buried waste. The plaintiffs claimed that soon after they began their farming operations, they began to experience a number of operational problems including cattle and chicken deaths, deformed calves and low milk production. In 1989, the Berendsens learned of the waste buried on their farm. Concerned about the health of and milk production from their cattle, they sought
The Berendsens argued that they were owed a duty of care because the Province should have known that careless disposal of waste roadbed material beside a water course on a farm might cause damage to the occupants of the land including the deteriorated health of cattle.
the advice of dairy specialists at the Ontario Ministry of Agriculture and Food (OMAF). A Ministry of Agriculture dairy specialist along with the Berendsens’ veterinarian wrote to the MOE summarizing their investigations and concluded that the water situation was adversely affecting the health of the Berendsens’ cattle. In other words, the cows were so reluctant to drink the contaminated water that their productivity and health were significantly affected. At this point, the MOE began testing the water on the Berendsens’ farm and constructed an underground water tank on the farm and paid for the supply of fresh water. When the cows had a supply of fresh water they became much healthier and milk production came more into line with normal expectations. Testing by the MOE identified some contaminants in the subsurface groundwater. However, the MOE found that concentrations did not exceed Ontario
Drinking Water Objectives. At that point, the Ministry stopped paying for the supply of water to the farm. The health and productivity of the cattle declined again. The Berendsens hired a consultant, who did more detailed testing and found additional contaminants in the water including dioxins, furans, PCBs, PAHs and chlorinated hydrocarbons. By 1993, the environmental and agricultural consultants had concluded that the contaminants from the waste concrete and asphalt were responsible for the cattle’s problems. Eventually the Berendsens abandoned the property and moved to a farm with clean water, where they successfully re-established their dairy operation. Meanwhile, the Berendsens launched their lawsuit in 1994. Ontario vigorously defended, arguing that it was a public

Legal Affairs authority, acting under a statutory duty to fix highways, and was protected by the Public Authorities Protection Act’s six month limitation period (no longer in effect). In 2001, the Supreme Court of Canada held that the MTO could not use the Public Authorities Protection Act. It could not claim protection for the acts of its highway contractors. The burying of the waste asphalt beside the stream on the farm was not work that was required by the statute – it was an operational decision made at the discretion of MTO, and was not protected. The Supreme Court sent the case to be tried, and the trial took place in 2006. On January 18, 2008, Superior Court Judge Seppi awarded the Berendsens $1.7 million dollars in damages, including significant damages for business losses. The Province argued that because the water that it tested did not exceed the Ontario Drinking Water Objectives, the Province did not owe a duty of care to the Berendsens. The Berendsens argued that they were owed a duty of care because the Province should have known that careless disposal of waste roadbed material beside a water
course on a farm might cause damage to the occupants of the land including the deteriorated health of cattle. Moreover, they argued that the Crown, having caused, and knowing of the contamination of their water and the harm to their animals and business, had a duty to fix the problem. Superior Court Justice Seppi held that: 1. There were no considerations that would negate the Crown’s liability in this case; 2. The Crown employees knew or should have known that the harmful chemicals in roadbed materials buried near water on a dairy farm were likely to cause harmful effects on the users of that water, even if the deposit of roadbed materials as fill on farms was normal practice in the 1960s; 3. The Crown, having caused the contamination, had a duty to use its statutory powers of investigation and remediation in the Environmental Protection Act and Ontario Water Resources Act to investigate and remediate.
As it now stands, the decision in Berendsen v. Ontario suggests that provincial and municipal governments have a duty to disclose knowledge of potential health impacts from operations, and to take action to prevent further contamination and to remediate. Some legal observers see similarities with the Sydney Tar Ponds application for a class action. In January 2007, the Supreme Court of Canada cleared the way for Nova Scotia residents to sue the federal government and the government of Nova Scotia for failure to warn of environmental threats to health, and to remediate. On February 15, 2008, the Province of Ontario filed a Notice of Appeal, asking the Court of Appeal to dismiss the Berendsens’ claim, or to order a new trial. Only time will tell whether the courts are going to expand the liability of governments for environmental claims. Marc McAree and Barry Spiegel are with Willms & Shier Environmental Lawyers LLP.

Feeding sodium hypochloride using innovative drinking water disinfection technology ater disinfection is the most critical process in the treatment of water and wastewater. The world’s most universal and reliable means of water and wastewater disinfection is chlorination. Two fundamental methods include gas chlorination (Cl2) and liquid chlorination (NaOCl), otherwise known as sodium hypochlorite. Chlorination was introduced as a commercial water purifier in 1908 and has since been acknowledged as the optimum method for water disinfection due to its ability to provide residual protection throughout the water distribution system. As a result of safety concerns with handling gaseous chlorine, the application of Cl2 continues to decline while liquid chlorination and other alternative yet more recent technologies such as UV (ultraviolet light) and Ozone (O3) strive to be more promising and possibly safer means of disinfecting water and wastewater. Yet, liquid chlorination water disinfection has been proven to be the most effective, economical, and reliable application for treating water globally for over 50 years. Sodium hypochlorite is widely used in various processes for disinfecting and bleaching. Also referred to as NaOCl, bleach, hypo, or chlorine, it is typically supplied and dispensed in 5-20% concentrations by weight, with the higher concentrations being progressively less

stable. It is subject to degradation within the piping and pump systems as it releases oxygen gas and results in crystallization of the residual. If the gas or vapour is allowed to build up within the piping and reagent head in sufficient volume, a typical reciprocating piston metering pump, used for accurately feeding chlorine to the process, will not function properly as gas in the pump head is compressed. This minimizes the discharge check valve’s ability to open upon discharge stroke of the pump. Consequently, this effect could require that the pump be reprimed for operation. Reciprocating piston metering pumps or diaphragm metering pumps have been historically preferred in the dispensing of sodium hypochlorite because of their ability to accurately dose chemicals into a process stream with great precision and repeatability at a constant pressure. Additionally, the diaphragm metering pump is sealless and leak proof by design, with negligible maintenance and simple commissioning. Traditionally, the diaphragm metering pump industry has promoted the use of degas valves on the discharge port of the pump which diverts gas back to the suction supply source of the bleach. This method has been widely accepted and successful in many applications. However, the small diameter ports in the valve system tend to plug and require continuous flushing or cleaning through human intervention since the system is open to the atmosphere on the discharge side of the orifice. Additionally, an external bypass piping system and degas valve assembly require additional costs and maintenance while presenting more opportunities for undesired chlorine leak paths. Description of technology Pulsafeeder, a Unit of IDEX Corporation, in Rochester, New York, has developed a technology that provides a simple and intuitive pressurized flushing system integral to the pump head, specifically designed for metering sodium hypochlorite solutions with great accuracy and repeatability.
The Pulsar HypoPump.
The Pulsar HypoPump® was explicitly designed to meter the full range of concentrations of sodium hypochlorite and its vapours associated with heat and degradation of composition. It features a patented design that allows pressurized process fluid to cyclically flush vapours and liquids through the pump’s discharge check system while maintaining high performance and chemical dosing accuracy. The design is integral to the pump head and eliminates the need for bypass systems including piping, valves, fittings, and instrumentation. Most notably, this system is closed-looped and not open to the atmosphere at any point, therefore eliminating crystallization of the sodium hypochlorite. The distinctive design also enhances self-priming capabilities since the pump system automatically evacuates entrained air in the piping system and pump head. The HypoPump has been installed in hundreds of significantly troublesome installations throughout the world. For more information, contact firstname.lastname@example.org

Energy from Waste
Ukraine biosolids incineration project generates electricity while solving disposal problems aste is the ideal fuel. It is better than free. You donâ€™t have to buy it. People pay you to take it. It has a negative value. Combine that benefit with another. The vast majority of wastes are combustible. They burn and that heat value can be harnessed and converted into electricity with a highly efficient and clean-burning rotary cascading bed combustor that eliminates pathogens. Put up a power plant that charges collection fees for the refuse which it burns, and charges for electricity which it produces, and you have the ideal situation. The heat produced by a combustor is used to generate steam which is used to drive a turbine in order to produce electricity. The typical amount of net energy that can be produced per ton of municipal waste is about 0.67 MWh of electricity. Thus, about 600 tons per day of waste will produce about 17 MW of electrical power each day through combustion. Waste-to-energy technologies reduce or eliminate waste that is tradi-
tionally streamed to a "greenhouse gas" emitting landfill, or mine waste materials from existing landfills. Producing electricity from wastes directly through combustion eliminates the intermediate step of producing a combustible fuel commodity, such as methane, methanol, ethanol or synthetic fuels, and eliminates the need to contain potent greenhouse gas emitting fuels. Today, because all new Waste-toEnergy (WtE) plants in countries that belong to the Organisation for Economic Cooperation and Development must meet strict emission standards, modern WtE plants have dramatically changed over the years. While older plants neither recovered energy nor materials, most modern WtE plants reduce the volume of the original waste by 95-96%, depending upon composition and degree of recovery of materials. Now the technology exists to bring that to near 100%. A model WtE plant An innovative WtE system is being set up in the Ukraine. Odessa is the fourth largest city in the Ukraine, with
a population of a little over one million. The city is a major seaport on the Black Sea and the largest port in Ukraine. After the government finalizes the authorization and financial arrangements, it will be home to a plant that will cleanly and efficiently convert sewage sludge into electricity. For many years, the people of the Ukraine have used sewage sludge for agricultural fertilization. The high level of contaminants, however, has required them to seek a more environmentallyacceptable solution to this disposal problem. At the same time, as their economy develops, their energy supply has become substantially more costly and less available. They now have discovered an opportunity to combine these two substantial problems into one comprehensive solution. In the Ukrainian program, sewage sludge will be used as the basic biomass fuel powering an electrical generation plant. At the heart of the system is a clean-burning Rotary Cascading Bed Combustor (RCBC) linked to a boiler Odessa, the fourth largest city in the Ukraine is a major seaport on the Black Sea and the largest port in the Ukraine.

Energy from Waste and electricity-generating steam turbine. The RCBC acts like a clothes dryer. It spins fast enough to keep the fuel cascading for maximum combustion. The technology is being commercialized by Quality Recycling Equipment of Hendersonville, North Carolina. The system will burn over 50,000 tons of de-watered sewage sludge per operating year, and it will generate 33,507,000 kWh of electricity per individual location. The only supplemental fuel required will be for start-up, or when there is a heat value shortfall. Eleven Ukrainian locations are planned – one in conjunction with each major sewage processing module. Infox and Millington Solutions, Ltd, along with the Ukrainian government, have agreed with RCBC Associates, as part of a pilot program, to cooperate in testing and monitoring the sewage sludge to electrical energy systems under US emissions and operational standards. The Ukrainian pilot program will also use a smaller 1.5 mW turbine generator and a 10,000 pounds per hour combustor. The RCBC has been in development

It has progressed from a bench scale model in 1982, an incinerator version in 1983 – 1984, a 5,000 pounds per hour combustor/boiler, to a 10,000 pounds per hour combustor/boiler installed and tested for over 2,000 operational hours as part of the Northeast Tennessee Regional Integrated Energy Waste Management/Waste Utilization
Program in 1990 – 1992. Operation and fuel preparation While the RCBC combustor accepts a wide range of fuels, the Ukrainian plant will only use dewatered sludge as fuel. The fuels are fluidized mechanically in a three-dimensional pattern inside of the rotating drum. In-feed continued overleaf...

Energy from Waste materials are mixed, lifted, dropped, milled, and recirculated as they are moved laterally, in both directions, along the length of the fluidization drum as they are concurrently combusted. The rotating unit cascades and stirs the fuel, combining it with a sorbant such as limestone at about one pound per ton. The sorbant continually reacts with sulfur and HCI to form calcium sulfates and chlorides, which are removed as non-hazardous ash. The entire process results in a clean and efficient burn, leaving harmless byproducts. The resulting fly ash, at less than 1%, is inert, and can be combined with organic waste to produce marketable compost. Emissions are lower than those of liquid petroleum gas, putting them well within EPA standards. Keeping the combustion temperature below 1400 degrees minimizes the production of oxides and nitrogen. The

heat produced by the unit creates steam pressure which spins a 4.5/5.0-megawatt condensing turbine generator, which is fed out to the power grid. The chemical reactions take place at temperatures high enough to destroy pathogens, but low enough to greatly retard the formation of oxides of nitrogen. Unique internal and external fuels recycling systems foster high sorbant contact with combustion gases and extend fuel dwell times, assuring clean and complete combustion of waste fuels. The sewage sludge discharged from the municipal sewer processing plant contains between 80 – 96% water. In preparation for burning, the sludge is drained in a dewatering module to a maximum of 15% water content by weight. The water that will not be used as fuel is returned for purification. Dry sewage sludge is an excellent fuel for the RCBC because of its high combustibility. Dewatered sludge and bed materials 18 | July 2008
are stored to compensate for infeed downtime or variances in heat values, or the operating schedules of the sewer plant, the dewatering module, and the RCBC. The production and emission parameters are continually monitored, and the fuel and sorbant flows are varied as necessary. In this way, the temperature, steam, and emissions are kept within the prescribed parameters. If a red line limit exceeds three minutes, fuel feed is stopped, and the operation is shut down. Municipal solid waste as supplement Another use to which the RCBC will be put, is in the county of Harvey, Kansas. In this application, the fuel source for the RCBC will be derived from municipal solid waste (MSW). Quality Recycling, Inc. is helping the county set up a materials recovery facility (MRF) that will be tied into the RCBC for fuel preparation and the recovery of recyclable and/or marketable materials. This application is an environmentally-responsible solution to several more major environmental problems. When waste is landfilled, one ton of MSW produces approximately 62 m³ methane via the anaerobic decomposition of the biodegradable part of the waste. In some countries, large amounts of landfill gas are collected through rigorous containment methods. But the costs and energies that must be devoted to such methods are prohibitive. Another notorious problem with landfills is leachate. Older landfills were not set up with safeguards to reasonably prevent seepage into the groundwater. Even modern lined landfills can be plagued by inadequate containment of toxic contaminants. These plastic liners that are spread out at the base of the landfill can be punctured, torn, or otherwise compromised, and have a limited lifespan. MRFs typically remove and classify papers, plastics, metals, and other marketable recyclables, and bale or otherwise package them for resale. MRFs make an excellent line for RCBC fuel preparation, because they optimize the economic value derived from the incoming waste stream, while preparing the RCBC fuel. Not only does a MRF/RCBC combi-
nation eliminate the need for landfills, but it opens up a whole new field of possibilities for the mining of old landfills, many of which are severe contaminators. MSW can be freshly collected or mined from old or troublesome landfills. Other fuels that can be cleanly burned by the RCBC include "dirty" or high sulfur bituminous coal, anthracite coal waste, carpet and carpet scrap, wood wastes, tires and rubber wastes, auto "fluff" from car shredding plants, oils, solvents, coal wastes, tar, industrial sludge, and movie film. Add standard fossil fuels and biofuels to the list, and the RCBC's versatility is even more impressive. About the only thing an RCBC won't burn is metal. Some toxic wastes have also been shown to be rendered harmless by RCBC combustion. Combustion has particularly strong benefits for the treatment of certain waste types in niche areas such as clinical wastes and certain hazardous wastes, where pathogens and toxins can be destroyed by high temperatures. Examples include chemical multi-product plants with diverse toxic or very toxic wastewater streams, which cannot be routed to a conventional wastewater treatment plant. Sewage as renewable energy Perhaps the most exciting thing about RCBC technology is that it expands the definition of "renewable energy" sources to include problem wastes - many of which have a negative value. Negative value fuels change the whole equation for power generation, because they allow power plants to earn revenues from disposal fees as well as from consumers of electricity. It has become unnecessary to pay for fuels in order to generate electricity. There will always be an adequate supply of garbage. It isn’t necessary to create biofuels from scratch in order to generate power. You can destroy waste while creating energy. Trash is renewable. Waste is renewable. Sewage is renewable. You can take that to the bank. For more information, contact John Kosanke, Quality Recycling Equipment, Inc. E-mail: firstname.lastname@example.org

Richmond BC WWTP upgrades to high-output UV system
Aquionics UV disinfection system at the Richmond wastewater treatment plant.
he existing low pressure UV disinfection system at a wastewater treatment plant in Richmond, British Columbia, has been replaced with a high output medium pressure UV system from Aquionics. The WWTP serves the Riverport Sports and Entertainment Complex and surrounding residential areas in southern Richmond. The facility decided to switch to medium pressure UV because cleaning the low pressure system was very difficult. Each of the two low pressure units contained 24 lamps â€“ automatic wiping is not an option with that number of lamps, so cleaning had to be done either manually or with chemicals. This is an extremely time-consuming process that required the entire system to be shut down. The two Aquionics units, however, each contain just two medium pressure lamps, each of which is fitted with an automatic wiper that keeps the quartz
sleeves clean during normal operation. There is no need to shut down the system for manual or chemical cleaning and no danger of damaging the lamps or exposure to wastewater. The units are installed after a Sequencing Batch Reactor (SBR) and can treat a combined flow of up to 600 gallons per minute (2271 litres per minute) of wastewater from the adjacent sports complex and residential areas. The disinfected wastewater is discharged into the Fraser River. Each of the UV units is fitted with a monitor which measures actual UV intensity and dose from the two lamps, providing real time information which can be downloaded for record keeping. Operating the UV system is simple and, when lamps need replacing, it can easily be carried out by on-site staff. For further information, contact Peter Wang, e-mail: email@example.com

CONFERENCE REPORT Blue Mountain Resort hosts 2008 WEAO annual conference Photo Report by Steve Davey, Publisher
s keynote speaker at the Water Environment Association of Ontario’s 2008 conference, Dr. Jamie Benidickson, from the University of Ottawa, expanded on the material in his book, The Culture of Flushing: A Social and Legal History of Sewage. He pointed out that the first major modern wastewater treatment system was authorized by the British Parliament in 1858 for the City of London, following the introduction of Thomas Crapper’s patented water closets and the construction of a massive sewage collection system. Prior to that, Londoners had employed the Conservatory Method. Outhouse contents were simply collected and then transported to nearby farms for direct land application. Ultimately, water closets and sewerage systems were more convenient than the Conservatory Method, but this new approach to sanitation had unintended consequences, which became quite apparent during “The Big Stink”. This was the unflattering term given to the Thames River, which quickly became little more than an open sewer and a terrible health hazard. Having already invested heavily in building London’s sewer system, the British government had no choice but to authorize the construction of wastewater treatment plants. Dr Benidickson also commented on several modern issues, pointing out that in 1990 only 32% of the Sub Saharan population had access to basic sanitation. However by 2007, due largely to population increases, still only 37% had access to basic sanitation. Turning to Canada, he noted that animal waste is a major issue, due to the massive volume of biosolids generated. Another issue is safe drinking water for First Nations Communities with 85 systems still considered at risk Dr Benidickson said that climate change is also affecting the wastewater industry in several ways. As an example, he cited the increasing economic and environmental benefit of capturing and using biogas (methane), a potent greenhouse gas, to generate electricity. He also said he found it ironic that in London, England, climate change-induced water shortages have resulted in a proposed de-salination plant, which will use massive amounts of energy to operate. A “Catch 22” situation indeed! The 2008 Water Environment Association of Ontario’s annual conference was held May 25-27, 2008, at Blue Mountain. Their 2009 conference will be held in Toronto in April.

Ontario’s Minister of the Environment addresses OWWA/OMWA Conference ohn Gerretsen, Ontario’s Minister of the Environment, addressed the recent conference of the Ontario Water Works Association and the Ontario Municipal Water Association. The conference was held in London in April. Following are excerpts from his speech to delegates: “Drinking water protection involves almost everything we do at the Ontario Ministry of the Environment, and our work begins long before water enters plants, pipes and taps. With the Clean Water Act, we’ve taken a huge step forward by making the responsibility to protect drinking water sources a legal requirement. Nineteen local source protection committees are now working closely with their municipal partners to engage communities in protecting the sources of their drinking water. To that end we committed $120 million for communities and their partners so they can get the work done that’s required under the Act. “We are providing more than $23 million for additional technical work by both municipalities and conservation authorities to support source protection planning. Our government also established the Ontario Drinking Water Stewardship Program. Under this program, $7 million was invested in early action, education and outreach and special projects as part of a four-year $28 million commitment to encourage early action.
“I know that people in London and throughout this Ontario region are especially concerned about lead in drinking water. Testing required by our regulations has shown this to be a provincewide issue. “We have developed a workable Lead Action Plan that strongly protects human health. In June 2007, a new regulation became law, governing flushing and lead testing requirements for schools, private schools, and day nurseries. Special attention was paid to reducing the potential for lead intake by pregnant women and children. Our plan requires annual testing at day nurseries built before 1990 and at all schools, and private schools and semi-annual testing of taps in homes and businesses served by municipal and private residential systems. We developed these requirements based on advice we received from technical experts in lead in drinking water from across North America. We also received advice from Ontario’s Drinking Water Advisory Council. “Our testing requirements are intended to identify situations that need to be corrected when Ontario’s drinking water standard for lead of 10 micrograms per litre is exceeded. As part of the plan, municipalities must also account for the cost of lead service pipe replacement in the financial plans we are requiring for their water systems as

part of the municipal license in 2010. “I believe Ontario’s Lead Action Plan is a good one, but there is always room for improvement - and it is getting a lot of useful feedback from stakeholders. For example, there are concerns about costs and staff time required for sampling and testing. We are working with both the Ontario Water Works Association and the Ontario Municipal Water Association to address these concerns. “The strong relationship between us was also a valuable asset as we designed and now are implementing the new licensing program for municipal residential drinking water systems. This group played a big role in the development of the program; your efforts helped give Ontario Canada’s first Drinking Water Quality Management Standard to support a quality management approach to operating municipal systems. “The new licensing requirements for owners of municipal drinking water systems, as well as a standard of care for municipal officials, will help municipalities manage and operate their water systems to the highest possible standard. Some of the key benefits of the program are that it clearly states that everyone within the owner and operating authority’s organization, from the mayor to the operator, has a role to play in the provision of safe drinking water. The owner of the system (mayors and councillors) will be required to provide a written endorsement and commitment to the management system. “Quality management is the responsibility of the people who manage the drinking water system, not a ministry program dictating how the system must be managed. Knowledgeable staff within the organization will develop

Conference Report practices that make sense for their drinking water system. And the independent auditor confirms that these practices are being followed — you plan what to do and do what you plan. The quality management system allows organizations to store and update knowledge gained over the years from all staff and ensures that this information is available for everyone. “The program requires that information is reviewed every year, which ensures that practices are kept current and relevant; information will be kept in one central document, which is accessible to everyone. It also ensures that tasks are not duplicated and that staff are doing things relevant for their specific drinking
per cent by 2020. We’re also focusing on adapting to the climate change-related effects that are already with us. “To ensure that we are guided by innovative thinking and practical advice to meet this challenge, we have created an Expert Panel on Climate Change Adaptation. We have asked this panel to come up with practical public policy options that can help us prepare for the effects of climate change on our people and communities. “Climate change adaptation is also in-
cluded in two very important Great Lakes agreements that we’ve recently signed. Ontario worked hard to make sure that explicit climate change adaptation commitments were included in the 2007 Canada-Ontario Agreement respecting the Great Lakes Basin Ecosystem. “The Great Lakes Charter Annex, signed by Ontario, Quebec and the eight Great Lakes states, will help our waterways adapt to climate change by banning large-scale transfers out of the Great Lakes Basin.”

water system, not just tasks that have always been done. It also provides an opportunity for owners to promote their effective management of the drinking water system to the public, which in turn leads to an increase in public confidence. “In addition to the safeguards outlined, we have stringent drinking water standards, rigorous inspections of drinking water systems and labs and more drinking water inspectors. There are tougher penalties for endangering water, and greater transparency and accountability through the Chief Drinking Water Inspector’s annual reports. Of course, this work is increasingly taking into account the earth’s changing climate which is going to affect many things, from the quality of source water to the infrastructure that treats and distributes drinking water. “We recognize that climate change is already here.

Water reuse facility allows golf course and 900 home By Jeffrey McIntyre subdivision project to proceed
he many challenges faced by the water industry include everything from higher water demand and inadequate water resource supplies, to aging infrastructure and climate change. In order to illustrate the critical need for better water management, an appreciation of the challenges is required. The United States Environmental Protection Agency has estimated the 20year needs for water infrastructure investment in the US at $277 billion for drinking water systems and $388 billion for wastewater systems. The goal of meeting demand is certainly attainable and is a daily preoccupation of the water industry. Focusing on delivering viable services to various communities, the industry has developed a set of innovative solutions to supply water to growing populations in arid regions. Water reuse is one solution. Increasing the amount of reclaimed water for agriculture and commercial consumers will significantly ease the strain on rivers, lakes, and aquifers that provide us with clean and safe drinking water. Until the safety and value of reclaimed wastewater is understood, people will balk at the idea of using it. However, the idea is not a novel one. All of our water (including drinking) was at one point used for, or emitted by, some-

thing else and is part of a general cycle of rain, ground filtering and evaporation. Golf courses require significant volumes of water for irrigation. Many golf course owners are turning to water reclamation as an alternative source for irrigation water. The Ballantrae Golf & Country Club in Ballantrae, Ontario, 30 minutes north of Toronto, was approved for the development of 900 residential homes and has an 18-hole championship golf course on a 418-acre parcel of land. Facility design was accomplished in the winter of 1999. Construction was completed in May 2, 2000. The treatment facility is a 1.0 megalitre/day sewage plant that contains full biological and tertiary treatment for a 'green field' development. For a facility that is designed to treat 1045 m3/day sewage, with capability to expand to 1568 m3/day, the Certificate of Approval stipulates stringent effluent requirements for effluent nitrogen. Designed, operated and maintained by American Water Canada, the system relies on sequencing batch reactor (SBR) technology because of its inherent process flexibility. American Water Canada handled all aspects of the wastewater treatment system, including design, installation oversight and project management, as well as ongoing maintenance and operations.
Process There is no receiving stream for the sewage plant, and provincial regulatory authorities require a high level of treatment in order to permit discharge to subsurface. The wastewater is treated through a process that includes complete secondary and tertiary treatment with low lift pumping, vortex grit removal, dual sequencing batch reactors, continuous backwash tertiary filters, and ultraviolet disinfection. Submersible sewage pumps pump the sewage through in-line grinders to a forced vortex grit system. After grit is removed, sewage flows to the main SBR tanks for biological treatment and settling. SBR technology permits biological aeration, and clarification in the same tank. It also permits aeration cycles and non-aerated cycles to be field adjusted for optimal treatment. The SBR tanks employ jet aeration, to achieve high oxygen transfer efficiencies. Two SBR tanks are utilized, with provision to add a third in the future. Decant or settled effluent collects in a tank and is pumped to continuous backwash sand filters. The SBR tanks also are used for phosphorus removal, and alum is added to achieve this. Excess sludge generated in the SBR tanks is wasted to an aerated sludge holding tank. The sludge is hauled to a local sewage plant for final processing.
Environmental Science & Engineering Magazine
Wastewater Effluent is pumped to continuous backwash gravity sand filters to remove particulate matter prior to discharge through an ultraviolet disinfection system. Effluent then flows to one of two effluent holding ponds, before being pumped to an irrigation system in the summer, or into the ground in the winter. Results American Water Canada worked with Schickedanz Bros. Limited, the developer, to complete the second privately-owned and operated wastewater treatment facility in Ontario. In addition, the project was fast tracked to meet the developer's challenging scheduling requirements and detailed design was completed in two months. This facility has enabled the Golf and County Club to independently operate in a location not readily serviced by municipal utilities and to provide the grounds with much needed components for growth and development. The Ballantrae Golf & Country Club is a bluebrint for the future that has already won an outstanding planning award from the Ontario Professional Planners Institute, for taking new directions in innovative planning development and design.

In the United States, where the average household of four uses 350 gallons of top quality water a day and the per capita use is 341 billion gallons a day, there is a significant amount of water that can be reclaimed. Water supply management is an issue that affects us all. It seems that water, for many people, has become a
resource that is taken for granted. Research has proven that rampant, excessive use of the water supply will eventually lead to a crisis. From today forward, careful planning and conservation that focuses on long-term stability will be necessary to ensure that successful water management is a reality for everyone.

Environmental solutions are critical to oil sands future
ontinuing work on finding solutions to environmental issues is key to the future of Canada’s oil sands, according to the winner of the Global Energy International Prize. Dr. Clement Bowman received a medal from Russian President Dmitry Medvedev, in recognition of “the development of highly efficient technologies and utilities for extracting oil from oil shale and oil sands, thus contributing to the energy saving problem of humanity.” He is co-winner of the $1.3 million prize with Eduard Volkov and will provide permanent scholarships in chemical engineering at the University of Toronto and University of Alberta in the field of energy and the environment. On his return to Canada from June 7 award ceremonies in St. Petersburg, Russia, Dr. Bowman said there was a high degree of interest in Russia in environmental efforts related to continuing oil sands development in Canada. “A critical factor considered by the award committee was the leadership provided by the Canadian Academy of Engineering (CAE) in addressing the need for sustainable hydrogen and the recovery and storage of carbon dioxide,” Bowman said. Bowman said building a positive global image of Canada’s oil sands development will be a continuing challenge. “We have to keep working on the environmental aspects of its develop-

ment and clearly demonstrate to the world that we are committed to cleaning up any problems associated with it.” In an interview with the English-language news channel Russia Today, Bowman commented that, with global oil prices currently exceeding $120 per barrel, recovery of oil from the oil sands was very economical at $30 per barrel.

The oil sands currently produce about 40% of Canada’s oil. As vice-president of Esso Petroleum Canada, Dr. Bowman led the Esso Research Centre which is part of the Exxon global energy network. As a former president of the Alberta Research Council, he established consortia with international oil companies to explore research approaches in oil sands that had breakthrough potential.

Corporate environmental responsibility: Adding value to the bottom line By Scott Freiburger and Janet McKenzie orporate environmental responsibility adds value to a companyâ€™s bottom line. This may differ depending on sector, size and culture. Manufacturingbased businesses confront a wide range of environmental challenges, while small or service-sector businesses face a narrow range. Businesses of all sizes and sectors have improved environmental performance and realized a wide range of benefits from reducing waste to maximizing resource efficiency and improving product design. In general, there are many costs of doing business, no matter the size or sector. When it comes to protecting the environment, a company needs to ask the question: "What is the cost of not protecting the environment?" For example, it could spend $1 on implementing environmental practices that could prevent a spill from occurring, while the same company would spend $100 to clean up and/or mitigate the spill. A spill can carry a variety of cost perspectives, ranging from the short-term clean-up cost and long-term diminished produc-

tivity, to the long-term effects to the community in terms of health issues and property values. In this situation, implementing environmental practices is seen as an investment rather than a cost. For many companies, environmental stewardship is moving from government "push" to "business-led". As this change is occurring, proactive companies are finding more instances where environmental improvement initiatives, beyond those which are required by laws and regulations, create significant business value and competitive advantage. Forward-thinking business leaders recognize that the adoption of environmental management approaches is both valuable and necessary to sustain a business. Increased regulation, government policy and customer expectations are all forcing businesses to address the impact their activities have on the environment. Pressure to implement environmental management systems (EMS) has manifested itself in many industry sectors. For example, large corporations such as Ford Motor Company, General Motors, Honda, Toyota Motor Manufacturing,
and Xerox are requiring their suppliers to obtain ISO 14001 registration and driving considerable interest in environmental management systems. Whether you're in the automotive, manufacturing, retail or a service industry, managing issues such as waste minimization, water quality and conservation, energy efficiency, air quality, pollution prevention, spill management and regulatory compliance can all help improve the bottom line. Companies are increasingly investigating environmental management systems, either because their customers demand it or because it promises to offer opportunities for improvement. But what are the real benefits of an environmental management system? Many companies began environmental management certification efforts in the mid-1990s due to increased global competition, customer awareness, and the potential benefits both in terms of bottom-line performance and operational efficiency. Businesses have been able to achieve cost-savings by fundamentally examining the design and production of existing and new products. Such a program provides businesses with information about more environmentally preferable processes or technologies that have the potential to result in big cost savings through waste reduction, energy efficient operations and reduced water usage. ISO 14001 specifies the structure of an environmental management information system, commonly called an environmental management system or EMS, which builds on and adds to existing environmental efforts such as regulatory compliance, training, record keeping, emergency planning, and preparedness. An EMS integrates environmental considerations into and throughout all of an organization's activities, products, and services based on established business principles, allowing operations managers to address and continually improve environmental concerns based on the "plan, do, check, act" philosophy. To put things into perspective, a business that adopts and/or implements

Management environmental management practices will have a strong understanding of its environmental impacts and will be in a good position to prevent potential negative environmental impacts. A business that has a limited understanding of its environmental affairs may be exposed to risk in the form of unanticipated environmental events (i.e. spill) and their associated costs. Growing evidence suggests that good economic performance is compatible with good environmental performance. For example, firms in the Dow Jones Sustainability Index (companies that incorporate environmental and societal concerns into their long-term economic investment strategies) outperformed the 2,500 largest capitalized companies that make up the Dow Jones Global Index (with cumulative gains in nominal market value of 85 percent compared with 57 percent) between 1993 and 2003. The positive correlation between environmental and economic performance is especially apparent in industrial sectors with substantial exposure to environmental risk. This evidence challenges the tradi-
A company could spend $1 on implementing environmental practices that could prevent a spill from occurring, while the same company would spend $100 to clean up and/or mitigate the spill. tional notion that complying with environmental regulations saps profitability and suggests that going “beyond compliance” can result in a competitive advantage. For example, firms with better environmental records may be more attractive to investors due to reduced compliance costs and a lower risk of future liabilities (Hopkins and Johansson, 2004). Businesses must start viewing environmental activity as a profit rather than a cost and move from reactive to proactive management. A business that is able to implement an effective environmental management system may be able to reduce environmental waste and natural resource use, while at the same time improve the economic bottom line.

Ensuring proper performance of decentralized wastewater systems By Dennis F. Hallahan and Brian M. Davis he need for new approaches for wastewater management in conjunction with an increased emphasis on environmental sustainability is challenging scientists, engineers, regulators, and product manufacturers to develop innovative ways of testing and applying new technologies for decentralized wastewater management. Another catalyst is a barrage of new health codes that regulate decentralized wastewater system design and installation. Growing awareness of nutrient loadings to the environment from nitrogen and phosphorus, aquifer protection, and the value of water as a resource have come to the forefront. These codes continue to be amended to preserve and protect public health and natural resources. Each year, decentralized wastewater treatment systems discharge billions of
32 | July 2008
gallons of wastewater. Homeowners, regulators, and the community at large depend on these systems to do one specific thing for them â€“ work. In fact, everyone involved with these systems, from the homeowner to those at the state or provincial level, use and depend on these systems to perform for periods of 20-30 years or more, with routine maintenance and inspection, little cost, and preferably, no expensive repairs or replacement. In addition to meeting treatment design goals, these systems must maintain their structural integrity and storage capacity in order to perform for the long term. Companies that manufacture integral components for these systems (e.g., tanks, distribution boxes, leachfield chambers, piping) design and engineer each component to last for many years to ensure optimal performance and structural integrity.
The ongoing debate: sewered versus unsewered The traditional centralized approach to water use and wastewater treatment involves extracting water from an aquifer or surface water body, treating it (in the case of surface waters), and sending it out through a potable water distribution system to homes and businesses. Then the water is used and delivered back through a collection system to a treatment plant for treatment, followed by discharge to a receiving water body (e.g., a river) where it is carried downstream. This treated and discharged water can add more pollutants to our already impaired waters; moreover, this treated water is not returned to aquifers. With a centralized approach, each home in a development that goes on the sewer line exhausts more of our water resources.

Pressurized beds receive highly treated effluent. These systems are installed in golf course fairways.
A decentralized approach to wastewater treatment provides a sustainable water use model. We can extract groundwater, consume it, treat the wastewater on-site and return it to its point of origin to recharge the aquifer. New decentralized wastewater treatment technologies that use natural approaches are less landintensive, provide sustainable long-term treatment and are leading to better de-
velopment practices. Due to the performance data now available that makes these systems increasingly popular with local health officials, the new on-site wastewater strategies and alternative methods of treatment are often the only solution for engineers and developers to obtain a code-compliant system. This is particularly true at sites with difficult soils and
tough terrain. The same scenario also applies to large recreational and commercial developments in environmentally sensitive areas where a combination of technologies must also be considered.

Wastewater tionary step in increasing the effectiveness and acceptance of standard and advanced on-site systems. Since the first concrete “gallery” chamber systems or “ameration chambers” (USEPA, 1980) were recognized for on-site septic leachfield applications as more efficient than previous traditional stone and pipe systems, chambers have evolved dramatically in design. Several years of research and design culminated with the introduction of plastic chambers to the marketplace in 1987 and these chambers are now commonly used for on-site treatment in basic and advanced applications. Because the chamber is highly adaptable and effective for specialized system designs and treatment needs, it is now a key element in septic system leaching trenches and beds, sand filters, mound systems, evapotranspiration beds, community (cluster) systems, constructed wetlands, large-scale wastewater treatment plants, pretreatment devices, and toxic waste remediation. The benefits of chambers are becoming recognized by many disciplines to solve a number of decentralized wastewater treatment challenges. Com-

Wastewater ations and maintenance cost savings vis-Ă -vis mechanical treatment systems, especially for systems that have to operate over long periods of time. Engineered wetland systems, through their complex assemblages of plants and natural bacteria, can provide a robust treatment system for both domestic wastewater and recalcitrant, difficult-todegrade synthetic compounds. Often, these two effective treatment approaches are used together in community system or cluster applications. The cluster wastewater system approach, employing engineered wetlands designed with subsurface chambers, is a viable alternative that allows for the preservation of community open space. These systems allow communities and developers to meet treatment requirements and economic goals. Cluster wastewater systems can easily be integrated into the landscape to preserve open space viewsheds. Community system To preserve open space and to protect the rural character of the community, Lake Elmo, Minnesota, refused to connect to the regional sewer. This conflicted with growth plans created by the regional planning agency, the Metropolitan Council, and a legal battle ensued that went all the way to the State of Minnesota Supreme Court. As a result, Lake Elmo was forced to accept regional sewer along the Interstate 94 corridor and limited use elsewhere. The remaining areas of the community, however, were able to retain their current wastewater systems. In 1995, a local developer, Robert Engstrom, proposed a development near the â€œOld Villageâ€?, the central area of Lake Elmo. His plan, called The Fields of St. Croix, was to mirror the Old Village with large tracts of open space surrounding a cluster of homes to be served by a decentralized water and sewer system. No ordinances were in existence to accommodate such a request and wastewater treatment was a concern. After months of work with the City and State, the development was able to proceed with the first state-permitted subsurface flow engineered wetland in Minnesota. This was the beginning of open space developments using decentralized wastewater technology within the community of Lake Elmo. There are now eight cluswww.esemag.com
ter treatment systems in the area, treating a combined flow in excess of 118,000 gallons per day. These systems employ both horizontal subsurface flow and vertical subsurface flow engineered wetland wastewater treatment systems. Subsurface infiltration chambers are used for treated wastewater disposal using infiltration beds and trenches. The chambers are engineered to increase the surface area available for infiltration of treated wastewater to the subsurface.
Performance testing and predictive tools increase in importance Testing infiltration chambers in the field is integral to obtaining accurate results regarding chamber performance characteristics. This in situ testing allows real-world conditions to be replicated including such factors as the impact of the weight of the soil on different infiltration chamber products.

Wastewater University Department of Entomology, Soils, and Plant Sciences measured the in situ liquid storage capacities of chambers, multi-pipe systems, and synthetic aggregate bundles, as compared to a conventional, 36-inch wide, 14-inch high stone trench. The study showed substantial differences in storage capacity between manufactured drainfield products and the stone trench. Included in the study were plastic infiltration chambers (of many sizes) widely used in the US and Canada, stone and pipe trench, multi-pipe systems, and synthetic aggregate bundles. In the study, the Infiltrator chamber products tested provided a storage capacity that exceeded the storage capacity of a comparable width stone trench. ISI’s Standard chamber models, designed for installation in a 36-inch wide trench, provided more than two times the storage of a 36-inch wide stone trench at the inlet pipe invert height. ISI’s Equalizer® 36 chamber model, designed for installation in a 24-inch wide trench, provided a total storage capacity equal to a 36-inch wide stone trench at the inlet pipe invert height. The Equal-
izer 24 chamber is intended to be compared to a 2-foot wide stone trench and thus does not provide an “apples-toapples” comparison with the 3-foot wide trench products. The study results provide a practical tool for the designer to select a product that can address storage capacity design issues. When chambers are employed for the design, a larger safety factor during peak flow events is provided. It also can serve as a basis for regulators to determine minimum storage requirements and compliance. Computer modeling as a predictive tool The Hydrus numerical model developed by Jacques Whitford NAWE Inc., is used to determine the increase in water table elevation and to assess the potential for treated wastewater ponding and groundwater mounding in a treated wastewater distribution system. As with any model, results are a function of the degree to which site characterization has been performed. For example, soil heterogeneities that are not measured in the field, and, therefore, not entered into the model, can produce results which
may be different than those measured in the field. Site characterization is, therefore, of great importance in creating a model which best represents field conditions. One of the primary concerns of designers, regulators and operators is the potential for the treated wastewater distribution system to fail, defined by the ponding of treated wastewater at the land surface due to low permeability soils or the surfacing of the water table. Proper design of a subsurface distribution system involves a number of critical steps: the design flow must be known; the acceptable hydraulic (linear) water loading rate to the subsurface must be determined; the distribution pipes must be sized correctly in terms of length, diameter, orifice diameter, and orifice spacing; and pumps must be sized at the appropriate flow rate. The linear loading rate is determined through analysis of soils obtained from soil borings and test pits, with the soil being analyzed for redoximorphic features, color, texture, structure, and consistence.

Wastewater water flow equations amenable to spreadsheet programs are sometimes used to determine water table mounding beneath drainfields (Hantush, 1967; Finnemore, 1983). However, these solutions do not incorporate soil heterogeneity, are not amenable to estimating water flow in variably saturated soils, and can sometimes provide unreasonably high estimates of water table mounding. Soils beneath a drainfield are variably saturated and, therefore, require a numerical solution to solve the equation describing water flow under variably saturated conditions. A numerical solution is needed to solve the Richards equation (1938), in which hydraulic conductivity is a nonlinear function of water content. The use of the Richards equation (Equation 1) is critical in properly estimating ground-

water mounding and treated wastewater ponding potential in the variably saturated zone beneath and downgradient from a drainfield. Hydrus (now in 3D) provides a Microsoft Windows-based modeling environment for analysis of water flow and solute transport in variably saturated porous media (Šimůnek et al., 2006). Hydrus Version 1 has been recently released as a major upgrade and extension of the Hydrus-2D/Meshgen-2D software package originally developed and released by the USDA Salinity Laboratory in cooperation with the International Groundwater Modeling Center, the University of California at Riverside, and PC-Progress, a Czech numerical modeling software development company. The software package includes computational finite element models for simulating the two- and three-dimensional movement of water, heat, and multiple solutes in variably saturated media. In an example a Hydrus model was constructed based on a site cross-section. The influx of treated wastewater
was shown to decrease the distance between the land surface and water table beneath the drainfield from approximately 11 ft to 0.66 ft. Conclusion As decentralized treatment technologies continue to grow in the market as the solution of choice and as these technologies continue to evolve, it will remain critical for those involved in using these valuable systems to become better educated regarding performance during product development and prior to installation. There must be a solid understanding of desirable long-term operation standards and the structural capacities to design systems accordingly. Engineers, contractors, regulators and homeowners all share the same goal – they want these systems to perform well for years to come.

Guest Comment water has been completed. EBR Petition File No. 07EBR014.R will have the Ontario Ministry of the Environment reviewing the existing policies and regulations under the Safe Drinking Water Act (SDWA). Québec City Council voted on April 1, 2008, to discontinue fluoridating its drinking water. An interesting opinion was written on Page 38 in the March 2008 Chatelaine magazine over Québec City’s move to stop fluoridation. The question was: “Is it harmful?” The response was written by Dr. Hardy Limeback, head of preventive dentistry at the University of Toronto. Dr. Limeback feels we’re ingesting far too much fluoride. He explains that in areas where the water is fluoridated, adults consume two to four milligrams of fluoride per day, two-thirds of which comes from drinking tap water. New studies have linked overexposure to fluoride with thyroid problems, hip fractures and dental fluorosis. Health Canada requires warning labels on fluoridated toothpastes. The US Centers for Disease Control and Prevention and
the American Dental Association caution against using fluoridated water for making infant formula. On April 14, 2008, Dryden residents voted 87% against drinking water fluoridation. This after a heated public relations battle that brought into the area two fluoride heavyweights: Dr. Peter Cooney, Chief Dental Officer for Canada, and the Fluoride Action Network’s Paul Connett, Ph D., who made separate presentations to the citizenry. So what’s happened regarding fluoride to bring about these changes? Artificial drinking water fluoridation has been a contentious issue for 63 years. Simply stated, the once common belief that fluoridated drinking water prevents tooth decay is false. “Fluoride’s caries-preventive properties initially were attributed to changes in enamel during tooth development because of the association between fluoride and cosmetic changes in enamel and a belief that fluoride incorporated into enamel during tooth development would result in a more acid-resistant mineral. However, laboratory and epidemio-
logic research suggests that fluoride prevents dental caries predominantly after eruption of the tooth into the mouth, and its actions primarily are topical for both adults and children.” Centers for Disease Control; MMWR Weekly Report. 1999;48:933-940. Government agencies like CDC, EPA, WHO and Health Canada all have information endorsing community water fluoridation (CWF) as a policy. But none have performed valid scientific primary research about the effects to the human body when HFSA is ingested. “Dentists are puzzled as to why fluoridation no longer appears to reduce dental expenses or decay. Perhaps it was poor historical studies failing to include confounders such as socioeconomic differences or delay in tooth eruption caused by fluoridation. In any case, after 60 years of fluoridation, evidence for the effectiveness of fluoridation cannot be demonstrated. Several studies have been done where fluoridation has been stopped and a cessation of fluoridation does not result in an incontinued overleaf...

Guest Comment crease in dental decay.” Dr. Bill Osmunson, DDS, MPH, 2008. Calcium fluoride (CaF2), a natural mineral found in ground and surface waters, is not the same as the pharmaceutical grade sodium fluoride (NaF) used in dental treatments. These products are 20 times more toxic and must be prescribed and used under professional care. Toothpaste formulations carry warnings against swallowing, calling poison control centres and prohibitions for use by children. Why? Fluoride is poisonous. But drinking water treatment facilities don’t use NaF, they use inorganic silicofluorides, mainly in the form of HFSA. HFSA is a liquid industrial waste from the super phosphate fertilizer industry. An assay of HFSA will list trace co-contaminants of lead, arsenic, mercury, cadmium and radionuclides as supplemental constituents of the solution. These substances are present because they wash down in stack scrubbers used to prevent toxic fluoride emissions into the air. Raw HFSA is shipped directly to water treatment fa-

cilities, unprocessed. HFSA has never been proven safe for human ingestion or effective at preventing dental decay. Why has this situation occurred? Simple, follow the money. There’s a cost saving to a multibillion-dollar industry by processing liquid industrial waste through human kidneys.
“If this stuff (silicofluorides) gets out into the air, it’s a pollutant; if it gets into the river, it’s a pollutant; if it gets into the lake, it’s a pollutant; but if it goes right straight into your drinking water system, it’s not a pollutant. That’s amazing!” SOURCE: Dr. Hirzy 2000 – USA Senior EPA Chemist.

Guest Comment “In regard to the use of fluosilicic acid as a source of fluoride for fluoridation, this agency regards such use as an ideal environmental solution to a long-standing problem. By recovering by-product fluosilicic acid from fertilizer manufacturing, water and air pollution are minimized.” Rebecca Hamner 1983 US EPA. What’s the harm? Aren’t the contaminant concentrations of HFSA below the maximum acceptable concentration (MACs) for drinking water? No. The argument is that the contaminants are diluted into treated drinking water to levels below the MAC. By diluting high quality water with HFSA, the finished drinking water is degraded from its treated state. HFSA addition does nothing to enhance, purify or improve the quality of drinking water. So adding HFSA is adding known toxins into drinking water which is in direct violation of Ontario’s SDWA. Sections 20 (1) and (3) are clear about this prohibition and dilution is no defence. Section 166 indicates that the SDWA takes precedence over the Fluoridation Act. This information is the crucial authority for stopping fluoride addition to drinking water. Facility owners and overall responsible operators (OROs) have a duty of care to cease the practice until the safety for doing so is established. In light of the new information of health harm, relying on historical precedent is no excuse not to act now. What are the health effects of ingested fluoride on other body tissues? Fluoride is an enzymatic reactor. It reacts and interferes with various chemical functions of the body. Fluoride at levels of 5 mg/kg can be lethal, but low levels of fluoride over long periods of time will cause or contribute to serious long-term health damage. Some of the dental and medical risks raised by the NRC 2006 report, of fluoride from all sources including current levels in drinking water, included: tooth enamel damage, gum disease, arthriticlike pain, bone cancer, osteoporosis, bone fractures, thyroid suppression, kidney damage, reproductive problems, lower IQ and increased mental retardation, allergies and gastrointestinal disorders. Dose vs. concentration is another aspect that no longer holds up to scrutiny. www.esemag.com
The concentration range allowed for fluoride in Ontario is now 0.5-0.8mg/L. However, the Gallagan-Vermillion formula for establishing fluoride concentration states that colder areas require a higher concentration of “optimal fluoride”(the fluoride industry euphism). So, by the G-V formula, much of Canada should be fluoridating to levels above 1.1mg/L while Ontario mandates optimal concentrations that are 28% to 55% lower. Contrast the previous sentence with the Centers for Disease Controls’s fluoridation manual that states "...even a drop of 0.2mg/L below the optimum level can reduce dental benefits significantly." So what's the benefit? How can the dose be determined for different water consumers? Infants, athletes, outside workers, soldiers, diabetics and kidney patients each consume more water than normal, therefore they receive more mg of fluoride per kg. of body weight. “90+% of European Governments and Dental Associations have rejected, banned, or stopped fluoridation due to environmental, health, legal, or ethical
concerns. Only six countries in the world continue to fluoridate. Both the Nobel and Pasteur Institutes have rejected fluoridation.” Dr. Bill Osmunson, DDS, MPH, 2008 Lastly, only 1% of treated water is consumed for drinking; the remaining 99% carries the dissolved inorganic fluoride through the wastewater treatment process and straight back into the environment. A survey of annual drinking water reports of eastern Ontario communities shows the levels of fluoride in Lake Ontario and the St Lawrence River increasing and double (0.24mg/L) what the provincial guideline is for the Lake (0.12mg/L). Evidence exists showing that aquatic organisms are harmed and fisheries are at risk. Find out the facts at fluoridealert.org or waterloowatch.com, and then, like Dr. Snow, act.

Analog flow meters replaced in California pumping plant he California Aqueduct collects water from the Sierra Mountains. The Edmonston Pumping Plant at the south end of the San Joaquin valley pumps more than two million acre feet of water annually over the Tehachapi Mountains for distribution into the Los Angeles and San Diego areas. Problem/issue/objective The plant operates 14 four-stage centrifugal pumps: 80,000 hp, Lift 1980 ft at 315 CFS. Each pump has its dedicated instrument panel with (nearly 30year old) analog meters monitoring temperature and flow. The “old” temperature gauges had multiple ranges, cap tube lengths (up to 50’) and bulb styles – causing a logistics issue. In addition, the time to replace one temperature gauge was in excess of four hours. The direct indicating flow gauges were DP flow meters with remote orifice plates. The gauges were used for
permissive points to allow the pumps to start, to alarm and trip on high and low flows and visually monitor the cooling water flow. The flow meters were high

log meters with state-of-the-art technology instruments, which would also allow communication. The change-out schedule called for the replacement of three to four pump instrument panels per year. The program was launched towards the end of 2003; so far, a total of 16 panels have been replaced. System solution The Department chose Otek model HI-QTBS, a programmable intelligent controller with automatic tri-color (circular) bargraph/digital LED display, to replace both the temperature and flow gauges at each pump instrument panel. Each panel has a total of 17 instruments.
The HI-QTBS output feature allows transmission of serial data to a remote location, in this case the control room at ground level. The units installed here are Otek models HI-QTEK, either single or dual vertical bargraphs and digital display. Results Since the new instruments at the pump instrument panel (14 temperature and three flow) are basically the same, the logistics issue of multiple ranges, bulb styles, etc., no longer exists. One HI-QTBS instrument replaces six of the old-style analog meters. The frequent need for calibration has been eliminated. It is estimated that the time for replace-
ment (if necessary) of the new instruments is about one quarter of the time required for an old-style meter. The resolution/accuracy of the Otek instruments made it possible to cut back on the flow rates; thanks to the automatic tricolor feature of the HI-QTBS, the operator can easily see the temperature differential across all heat exchangers. The orifice plates for the flow meters were replaced with LF410 electromagnetic flowmeters, a 4-20mA output instrument. The Otek HI-QTBS meters were scaled to read in engineering units to reflect the true flow. Three relays in each device switch at Low, Permissive and High Flow. The tri-color display changes color at the set points thus giving a vivid indication of the status of the flow. Based on the reduced downtime alone, the payback on the first installation of Otek instruments was estimated at 12 months.

Seeking neutrality in the war against carbon emissions
Royal Roads University sits within the Hatley Park National Historic Site.
t Royal Roads University, environmental sustainability is the core of the institution’s founding philosophy. For example, the university uses chemical-free cleaners and an award-winning irrigation system that taps an independent groundwater source. More than 70 per cent of campus garbage is diverted from the landfill through recycling and organics composting. Bicycling and carpooling are encouraged. The list goes on. So when a RRU professor challenged his students to a “carbon neutral residency,” it seemed a logical next step. Environmental economist Charles Krusekopf, an associate professor in the School of Environment and Sustainability, offered carbon-offset credits for $25 per tonne to his students in the Masters in Environmental and Management program, effectively using cash to zero greenhouse gas (GHG) output. Most of the 140 students’ measurable carbon contributions (estimated from online GHG calculators) came from airline flights. In RRU’s blended residency, distance-learning model, a typical graduate student would travel to Victoria three times for three-week residencies over two years. Round-trip travel from Toronto, for instance, contributes slightly less than
44 | July 2008
one tonne of GHGs to the atmosphere. Krusekopf says the project isn’t about making money, but demonstrates how people can make actual reductions to carbon dioxide emissions. Tax-deductible carbon credit funds are held in the “RRU Sustainability Fund,” set up by Krusekopf and managed by the RRU Foundation. The foundation is matching contributions dollar for dollar, and the money will eventually subsidize energy efficiency and sustainability projects on campus, starting with small projects such as switching rooms to compact florescent lighting and installing light activation sensors. “We could probably reduce our energy by 10 per cent for a low cost. After that it gets progressively more expensive,” Krusekopf said. He cautions that greening the university is still in its early days. The $25 carbon credit price tag was picked from the air and isn’t yet based on any larger plan. A cohort of undergraduate science students is investigating RRU’s total carbon footprint, but results are not expected until later this year. For the first try at a carbon neutral residency, Krusekopf raised about $4,000, theoretically enough to cut 160 tonnes of GHGs. He says the environmental management learners met or ex-
ceeded their offsetting goals. Environmental management learner Ginny Stratton creates carbon neutral events and conferences in Vancouver through detailed sustainability measures – everything from ensuring non-toxic inks are used on chemical-free paper, to bio-diesel in vehicles to 100 per cent recycled coffee stir-sticks. Many expect Krusekopf’s project to push Royal Roads towards a carbon neutral campus within a decade, but it won’t be easy. The university sits within the Hatley Park National Historic Site and all 11 classroom and office buildings have heritage status, from either the Dunsmuir estate or the military college, making environmental retrofitting expensive and bureaucratically complicated. Becoming carbon neutral is a challenge, but RRU is probably in a much better position than other universities in Canada. Future buildings, such as the Robert Bateman Art and Environmental Education Centre, could go beyond platinum LEED to what is coined a “living building”. The university’s commitment to sustainability could make it a showcase campus. For more information, E-mail: Karla.Hitchcock@RoyalRoads.ca

Loss of pollinators may be serious threat to plants and people ne of the bumblebees that was most common in Southern Ontario when today’s baby boomers were teenagers has all but disappeared, a York University study has found. The study provides the first quantitative evidence of the decline of bumblebees in North America by comparing recent numbers with statistics gathered in the early 1970s in Ontario. It also tracks the dramatic decline of one species that is native to eastern Canada (including Ontario) and many US states. The article “Evidence for decline in eastern North American bumblebees, with special focus on Bombus affinis Cresson,” appears online in the journal Biodiversity and Conservation. Its findings are disturbing because the loss of any pollinating species can have cascading effects on native plants and crops, and on anything that relies on them. Lead author Sheila Colla, a PhD candidate in York University’s Department of Biology, studied the number and types of bumblebees at two sites in southern Ontario over three summers from 2004 to 2006, and compared them with baseline numbers from surveys at the same sites in the early 1970s. Colla slowly paced one kilometre across the sites at regular intervals, collecting all male and worker bumblebees as they foraged for pollen and nectar. There were fewer bumblebees overall at the two sites – in southern Guelph and the Town of Belwood – and half of the 14 species found in the 1970s were either missing or in decline. When Colla looked further afield and focused in on one species of bumblebee, she found the Bombus affinis had been nearly eliminated, not only in southern Ontario but throughout its native range. “I found only one of the Bombus affinis species – one single bumblebee – at Pinery Provincial Park on Lake Huron, and I had looked for it at 43 sites from Ontario to Georgia, and east to Boston,” said Colla. “This is alarming because it appears to have been almost eliminated, and in the early 1970s it was
one of the top four bumblebee species in southern Ontario.” Each species has its own preferred flowers and its own season, says Colla. “Bombus affinis appears early in April, while other bee species make their first appearances in June. So if you knock one species out, there may be a few weeks where there are no bees pollinating some plant species.” Bees and bumblebees are vulnerable to extinction for many reasons – includ-
ing pesticide use and lack of habitat – but there have not been many extensive surveys in North America, despite their ecological and economic importance as pollinators. Colla’s results are similar to patterns observed in Europe where bumblebees have been more closely monitored and half of all bumblebee species have been shown to be in decline.

New in situ process removes salt from contaminated groundwater enturies ago “salting the earth” was used in war to punish neighbouring countries and to discipline landowners who went against the status quo. The practice involved sprinkling salt over the land, making it unusable for farming for generations. Today, salt contamination in soil and groundwater is a multi billiondollar environmental problem for other reasons, and a Canadian company has figured out how to solve it in situ. Ground Effects Environmental Services Inc. (GEE) is an environmental remediation company based in Regina, Saskatchewan. In 2003, GEE’s R&D division began testing a new treatment process the company calls the EK3 Electrokinetic System. EK3 removes salt contamination in situ from lowpermeable soils (such as clay) and groundwater using electrokinetics. The technology has made the transition from theory to practice with several pilot studies and projects already completed with promising results. Another overarching benefit to the technology is that it can effectively treat salt contamination onsite in large areas with little disturbance to the environment. Salt contamination is a problem for two reasons: 1. Almost every northern town, city and province or state uses salt to clear roadways of ice. The salt leeches from roadways and salt yards into the groundwater and soil. 2. Salt is a by-product of oil production. Oil-bearing formations can occur
46 | July 2008
below a layer of salt-bearing rock. When tapping the reservoir, water is used in the drilling process to remove the cuttings from the well. This water, along with the groundwater, mixes with the existing salt. The newly-formed salt water is extracted along with the oil from the well. Ideally, the salty brine is separated and disposed of; however, sometimes it spills. GEE estimates that salt contamination is a billion-dollar problem in Alberta alone. According to the company’s research, each contaminated site will cost $0.5 - $2 million to clean up. There are tens of thousands of sites in Alberta alone. The EK3 process is fully automated and can be operated over the Internet from anywhere in the world. “The EK3 system doesn’t need personnel to run it; customers can change settings whenever they wish over the Web by means of user-friendly remote telemetry,” comments Sean Frisky, GEE’s founder and president. In addition, the system continuously monitors itself and changes its settings based on preset programming so that maximum efficiency is achieved. How does it work? EK3 uses electrokinetics to remediate the contaminated area. A low-voltage, direct current (DC) electric field is applied across a section of contaminated soil. The electric field causes the contaminants to be mobilized, concentrate at the electrodes and be ready for extraction. GEE employs three principles of electrokinetics to achieve remediation: electrochemical reduction/oxidization, electromigration and
electroosmosis. Electrochemical reduction/oxidation (Redox) is the chemical reaction in which atoms can have their oxidation number or oxidation state changed. This reaction changes the chemical make-up of the contaminants at the molecular level, readying them for electromigration and electroosmosis. Electromigration involves the movement of ions towards the respective electrodes. Cations (positively charged ions) begin to move toward the cathode (negative electrode) and anions (negatively charged ions) move toward the anode (positive electrode). The ion movement is important when treating soils contaminated with metals, nitrates, chlorides, sulfates and salts. Electroosmosis is the uniform movement of water and contaminants from the anode to the cathode. Since clay soil typically has a negative surface charge, there are more cations than anions in the pore water. These extra cations, lined up along the pore walls and moving toward the cathode, drag the pore water along causing a net pore water flow to the cathode. This process can effectively dewater a section of soil as well as carry contamination into an extraction area. Recent laboratory and pilot studies show excellent results. GEE took one cubic metre of packed clay saturated with ten thousand parts per million (ppm) of NaCl and applied the EK3 system to it. The results were beyond what the company had originally projected (Fig. 1 & 2).

These soil samples show that the salt molecules separated into their ions and migrated towards their respective electrodes of opposite charge. Cl (mg/L) went down from 1300 ppm to 49 ppm (with 200 ppm being the criteria or measurement of success). Na (mg/L) was reduced from 488 ppm to 38 ppm (again with 200 ppm being the criteria or measurement of success). Currently, two full-scale EK3 projects are underway. The results show there has been a decrease in the electrical conductivity of the soil, which correlates to the NaCl content of the soil. (Fig.2) Heavy metal and PCB applications GEE’s R&D division is continuing to research other applications for the EK3 technology. The latest lab testing involves applying the EK3 electrokinetic approach on polychlorinated biphenyls (PCBs), trichloroethylene (TCEs), heavy metals and heavy end hydrocarbons in soil. Known for a long time as hard-toremediate contaminants, PCBs, TCEs, heavy metals and heavy end hydrocarbons are typically dealt with through ex situ remediation or “dig n’ dump” where the contaminated soil is excavated and transported elsewhere, sometimes to a facility where it is remediated, but more often to a landfill. In the case of PCBs and TCEs, high temperature treatments are applied offsite after removal in order to complete the remediation, often an expensive process. EK3’s in situ approach is different. In a process the company’s R&D division is terming “tetra phenomenon,” EK3 uses the biological, geological, www.esemag.com

chemical and electrical forces inherent in the environment to help it remediate, doing so in a way that’s environmentally sound, with little disturbance to the contaminated area. The four factors continually at work are chemical, biological, electrical and geological phenomena. Through intensive management of these elements, overcoming the challenges of contamination breakdown and extraction becomes straightforward. Chemistry The key to understanding what is occurring lies in the makeup of the contaminant itself as well as the potential chemical reactions occurring through the application of DC current. The EK3 technology not only has the ability to manage these chemical reactions, but it can also stimulate further beneficial reactions that assist in the extraction of the contaminant. Biology This little understood factor in site contamination actually plays a significant role in both the form of contaminant as well as extraction techniques. The key players within the phenomenon are the microscopic bacteria that, until recently, were thought not to survive in such a harsh environment. The bacteria have the ability to form tight matrices throughout the site of contamination, binding the contaminant tightly to the sand/silt particles. This contributes to the known difficulties in extraction. When the EK3 process breaks apart the biofilm surrounding each of the soil molecules, removal becomes much more viable.
Geology The type of geology where the contaminant is located can play a role in some remediation and extraction methodologies. The EK3 technology does not depend on a specific geological formation for success and is capable of performing well in all types of formations, including those with low permeability. Depth is also irrelevant to the technology success. Kinetics The application of direct current (DC) to the electrodes plays a significant role in EK3 technology. Through the combination of knowledge and management of the above three phenomena, DC is the driving force that makes EK3 effective. The current applied allows specific soil kinetic reactions to occur. These include electroosmosis, electromigration, electrophoresis and electrical resistive heating. In early testing at GEE’s R&D lab, EK3 is showing promising results in cleaning up these contaminants. The company continues this testing and anticipates releasing complete results by the end of 2008. Ground Effects Environmental recently won two awards for this technology at the Innovation Awards Gala of the Canadian Advanced Technology Alliance, which was held in Ottawa in June. The company won the 3M Canada Award for Excellence in Emerging Technology, and the Northern Light Award “Best of the Best”. For more information, E-mail: firstname.lastname@example.org 47 | July 2008
Environmental monitoring is a big factor in resource company planning
by Martin Jalkotzy
Resource roads can have a significant impact on wildlife populations, in part through allowing easier access for predators, four-footed and two-footed.
onitoring the ongoing environmental effects of resource development projects is climbing up on the priority lists of resource companies and the environmental professionals who advise them. However, more changes are needed if this planet’s resources are to be used in a way that allows economic activity to continue while also protecting the environment and meeting the needs of other stakeholders. This includes the improvement of methods for monitoring of environmental performance both during and after operations. Some of these changes are already occurring, so the needs of the environmental monitoring process are starting to influence the way environmental impact assessments and mitigation measures are carried out. Consider some of the factors involved. Environmental performance is becoming a much bigger part of resource companies’ considerations. Before public concern about the global environment became a major factor, resource companies were under relatively little pressure to manage their environ-

mental impacts. In recent decades, public concern about wildlife habitat loss, water and air pollution, climate change and other factors has resulted in a host of new regulations in jurisdictions all over the world. As well as regulatory concern, there are financial pressures. The rise of socially-responsible investing through “green funds” and environmentally-related shareholder activism push publicly-listed companies toward higher environmental performance.

Internet-savvy non-governmental organizations can mount quick international pressure campaigns against companies whose actions they see as harmful to the environment, local communities and other stakeholders. A company’s “social licence to operate” is becoming as important as its government-issued permits. A company that has a reputation for environmental disregard, or for circumventing the wishes of the local population, will increasingly find it difficult to operate. This means that companies need to be seen not just to comply with the minimum regulations, but to be seen to go

Monitoring dictions has long required an Environmental Impact Assessment (EIA) before resource extraction begins. As a part of the permitting process, the company makes a commitment to keep environmental effects at an acceptable level during the lifetime of the mine or other project. This means that, if environmental parameters are exceeded (i.e. the sediment levels in a nearby watercourse are getting dangerously high, potentially affecting fish-spawning success) corrective action can be taken. The approvals process also includes a commitment to reclaim the affected area to an acceptable condition and to manage the ongoing effects. The best way to tell if the company is meeting its environmental obligations is through ongoing monitoring. This can include a wide range of measurements, including emissions to the air and water, noise levels and wildlife populations. In most cases, the company will hire an external environmental consulting firm to do this work. This is partly because few resource companies have enough of the right professionals on staff,
and partly because outsourcing the work to neutral third party professionals provides greater credibility to the findings. But as the environmental monitoring teams show up with sampling containers, measuring devices and laptops to do the work, they may find some strange gaps in the data they’ve been given. In many cases, the baseline data – the

Without adequate baseline information giving a full picture of what was there originally, they cannot provide a full picture of any environmental or social impacts of the project.

they could be, in helping the company give evidence of its performance. It is not necessarily the case that the environmental professionals who compiled the baseline data did an inadequate job. It is just that their data-gathering was not done with the needs of the ongoing monitoring in mind. Why does this happen? The main reason is that, prior to the resource company’s receiving regulatory approval for its project, the focus of its senior executives is quite naturally on the need to receive that permit. Other matters, which might include the question of closure and reclamation many years in the future, may be seen as less of a burning priority. But as we’ve seen, environmental and social performance in the short and long term is becoming more and more important. This is particularly important for a junior resource company that wants to demonstrate the viability of its mine or other project in hopes of selling out to a major.

Monitoring and social issues need to be at a â€œgreenâ€? status, with no warning flags. The buyer will be willing to pay the most money for a problem-free acquisition. This means that environmental professionals conducting baseline studies have a responsibility to collect their data in a way that is congruent with the needs of long-term monitoring. For example, consider wildlife counts. The baseline study included in the EIA might have counts for some species, possibly the usual â€œflagshipâ€? top predators. However, it may not have data for species generally considered to be most indicative of the state of the habitat, or possibly the â€œumbrella speciesâ€? whose habitat requirements also meet those of a wide range of other species. Or, there may be insufficient data on how species are using the habitat. For example, some species such as deer use forest edges for grazing, staying close enough to cover so that they can hide when danger threatens. Other species, such as the fisher, need forested territory that has plenty of logs and other forest litter, in which to hunt their small-
mammal prey. Some species need rocky outcrops as hiding spaces. In studying the uses wildlife make of their territory, it is important to consider

factor in allowing wildlife species to reinvade reclaimed areas that have been disturbed by resource extraction. In establishing baseline data that can be used for monitoring, it is important to use all relevant current technology. This can include computer-based models that indicate high-value habitat for various species, while the land is still in its undisturbed state. Pointing to highvalue habitat may help guide resource extraction, possibly guiding tree-cutting, road construction and other disturbance away from areas of particular value. As resource extraction goes on and later as reclamation begins, updating the models can demonstrate to stakeholders how environmental concerns are being met. â€œBegin with the end in mind,â€? urges â€œSeven Habitsâ€? guru Stephen Covey. That applies to baseline environmental data collection as well. Martin Jalkotzy is a Senior Wildlife Ecologist in the Calgary office of Golder Associates Ltd. Contact: email@example.com

Mexican food processing plant chooses Canadian portable wastewater treatment system By B. Donald Prazmowski
The installation at La Mexicana, a tortilla manufacturer in Hayward, California.
BF Inc., a small engineering and R&D corporation, has been working since 1990 on perfecting a promising Canadian wastewater treatment technology. After 14 years of development, in July 2004, the Ontario Ministry of the Environment carried out a technology assessment and granted Dry Biofilter (DBF Inc.), a certificate stating that: “The Ministry concurs that the process, if sized properly, can be an effective trickling filter technology for treating high strength wastewater from the food industry.” After building several plants in Canada, DBF Inc. began marketing this technology in the US, where it was invited to build a wastewater treatment plant in Hayward, California. The City of Hayward is located very close to the ‘St. Andréa’s Fault’ where quite recently there was a minor earthquake measuring 5.6 on the Richter Scale. The plant swayed but did not spill a drop. But the reason why DBF Inc. was invited to build this particular plant for “La Mexicana,” a tortilla manufacturer and baker who had a 25 ft x 35 ft area available, was simply the fact it could build a wastewater treatment plant in such a small space. After careful study, DBF Inc. concluded that this totally Canadian wastewater treatment technology, with a very small ‘footprint’, could do what it has been designed for and that is installation in urban areas.
DBF Inc. used every square inch of the available space and built three – 32 ft tall ‘bioreactors’ and what was claimed to be the first ever, modular, vertically stacked ‘trickling” filter. The plant is working 24/7 and has been operating successfully for more than five years.
The DBF™ wastewater treatment system is a completely shop pre-fabricated, modular, road transportable wastewater treatment system and less expensive than site-assembled heavy equipment. A battery of bioreactors is normally connected in series and each is a totally independent, self-sustaining biological treatment unit. Each bioreactor can be isolated and bypassed for servicing, while the incomplete battery continues to operate normally. The complete system does not need to be shutdown for servicing as was the case with the La Mexicana plant. The efficiency of the process hinges on a rather complicated, carefully controlled dynamic where ‘old bacteria’ is separated from the young at an approximate ratio of 20% of old bacteria and 80% of young.

Brownfield site goes green with BioOil production plant here are many reasons why industry has increased its demand for alternative and renewable power or energy sources. A cleaner environment, need to save energy due to high oil prices, political pressure and changes in regulations, driven by increased environmental concerns, are just some of the reasons that encourage the search for energy alternatives to fossil fuels. Availability of inexpensive and abundant agricultural and forest residues (feedstock) in Canada makes the production of biofuels very feasible and attractive. There are three main advantages that can be identified for the use of biomass residue: abundant – low/negative value source; accessible – above ground reserves; and renewable – greenhouse gas neutral as a fuel. In addressing the demand for the production of biofuels, Dynamotive Energy Systems Corporation, which is based in Vancouver and specializes in the production of alternative energy, has developed and patented a unique process and technology to produce a type of biofuel produced from cellulosic biomass, known as BioOil®. What is BioOil? BioOil is a fuel that is used for industrial applications and is produced through a fast pyrolysis process using raw materials such as wood chips (sawdust) or cellulose-rich bagasse from sugar cane. Biomass residue usually has low energy density, making it inefficient to store and transport; low energy efficiency suitable only for use with boilers/steam turbines; a cost of disposal such as burning or transporting to landfills; a negative environmental impact if not treated due to methane emissions and groundwater pollution. If, however, this biomass is converted into BioOil, the following benefits are derived: increased energy density since BioOil is easier to store and transport; increased energy efficiency since it can be used in gas turbines/diesel engines; compatibility with existing fuel infrastructure; utilization, de-coupled from production;

greenhouse gas credits in the open market. In addition, the BioOil facility, unlike some ethanol production plants, does not depend on the use of food crops. BioOil is a free-flowing brown liquid that is neither a hydrocarbon nor oil. When burnt it produces 20 to 30% lower emission of nitrogen oxides when compared to conventional fuels and the emission of sulfur oxide gases is negligible. The combustion of BioOil is CO2 neutral. BioOil can be used as a replacement for #2 Diesel and #6 Bunker C heating oil or as input for the production of synthetic diesel. It can be used as base fuel for boilers, lumber/lime kilns, diesel and turbine engines. It can be used for the production of a fuel blend with ethanol, methanol and diesel in the creation of derivative fuels such as bio-methanol, syngas and synthetic diesel and to make specialty products or chemicals. Production process The fast pyrolysis process consists of flash vaporization or thermal decomposition of biomass at high temperatures in the absence of oxygen in approximately 2 seconds and 450 to 500 degrees Celsius. 100% of the biomass is converted or decomposed into usable elements and with no waste stream. The reactor products are cooled and approximately 70% of the biomass is converted into BioOil,
20% into char and 10% into non-condensable combustible gases which are recirculated as fuel for the pyrolysis reactor. The unit operations of the process are: • Pyrolysis reactor - deep fluidized bed of inert material; • Cyclone/char collector - where char is separated from the rest of the compounds and fragments; • Quench system - where the BioOil liquid settles for collection and cooled non-condensable, combustible gases are recycled to the reactor. Guelph’s BioOil production plant The Guelph, Ontario, BioOil plant which started operation in December 2007, was built on a 22 acre brownfield site. It is a 200 tonne per day plant and is the largest plant developed and built for commercial production in Canada When Dynamotive wanted to get the detailed engineering and construction of the plant expedited on a fast schedule it contracted consulting engineers Virtual EngineersTM , a Richmond Hill based firm, to provide the detailed engineering based on the basic engineers design from its partner firm TECNA S.A., an Argentinean firm that specializes in design and construction management of processing plants.

Saskatoon rehabilitates its South Downtown By Lalita Bharadwaj and Ray Machibroda riverbank area askatoon’s River Landing park development project has an extensive and fascinating history that extends over a 30-year period. The “River Landing” park development is part of a South Downtown Revitalization Project that was initiated in the 1970s when the City of Saskatoon secured core development funding from the Province of Saskatchewan to acquire land for the revitalization of Saskatoon’s South Downtown area. In 1978 the City commissioned a plan for the South Downtown that included a “South Downtown Concept” and supported the development of the South Saskatchewan River Bank, the site of the “River Landing” park development. Over the next 26 years, numerous development proposals and plans submitted by national, local and regional development firms were reviewed and debated. With public consultation, in June 2004, the “South
Dorr-Oliver ODS® Diaphragm Pump
Downtown Concept” was approved by City Council and the “River Landing” park development project was initiated. Preliminary studies were conducted at the site over a period of two years and included Phase I and II Environmental Site Assessments (ESAs), geotechnical investigations and a hazardous materials assessment. Information gathered from the initial ESAs revealed that inorganic materials (heavy metals), PHCs and PAHs, at concentrations exceeding the CCME (2006) Parkland/Residential (P/R) assessment criteria, were randomly distributed in soil fill. The soil fill materials, deposited sometime between 1956 and 1966, reportedly incorporated demolition debris, cinders and ash from a variety of sources including a former downtown rail yard and the power plant formerly located to the north of the site. Fill materials were utilized to increase the elevation of the site. Four major fill areas (i.e., Area Nos.
I through IV, inclusive) were identified on the basis of the ESAs. Chemical constituents measured in the soil fill included: heavy metals (i.e., arsenic, barium, copper, lead, mercury, nickel, selenium and/or zinc) and PAHs at concentrations exceeding the CCME (2006) P/R Criteria; and residual hydrocarbons (i.e., F2, F3 and F4) at concentrations exceeding the SENV (2006) Coarse Grained Residential Soil Criteria. Although contaminants were identified at grade, the contaminants exhibiting the highest concentrations were typically located at depths ranging from three to approximately five metres below grade. Exceptions to this were PHCs (i.e., F2, F3 and/or F4) which were detected at or near the ground surface. Even though only four major areas of soil fill were identified at the site, the randomness of the fill deposits suggested that other areas of impacted fill could exist. Further, the lack of infor-

Redevelopment mation regarding past use of the site suggested that identification of these fill areas was unlikely without extensive, costly investigation. Although remediation of the site could have been accomplished by removing the impacted materials, it was recognized that accurate costs for this option could not be established since the volume of impacted soil was unknown. In light of the above, a site specific Human Health Risk Assessment (HHRA) was employed to determine whether existing chemical constituents at the site would adversely affect the health of potential â€œRiver Landingâ€? park users. Risk assessment The HHRA process included the steps of hazard identification; receptor characterization; exposure assessment; dose/ response assessment; and risk characterization. The approach taken for each step is described in the subsequent sections. Hazard identification In the hazard identification step a selection process, based on human health considerations, was performed to identify contaminants of potential concern (COPC) at the site. COPC were selected

Redevelopment associated with human exposure. Through review of animal and human toxicity data the range of toxic effects attributed to potential exposure to COPC, along with the chemical fate and behaviour of the COPC in the body and the soil, were discussed in the hazard identification step of the risk assessment. Receptor characterization The second step in the risk assessment process involved the characterization of potential human receptors. Human receptor characteristics such as soil ingestion/inhalation rates, weight, skin surface area, age and time spent outdoors were obtained from Richardson (1997), summarized and then subsequently utilized to calculate estimated daily intakes of COPC. Since the proposed use of the site is a recreational park, three categories of human receptors, namely children, adults and construction/utility workers, were identified for assessment. The durations of the infant (0 to 6 months), toddler (7 months to 4 years), and child (5 to 12 years) categories were summed such that a full exposure duration of 12 years was used to assess potential risk. For adults and construction workers, standard receptor characteristics (Health Canada) were used and these individuals were defined as persons 18 years and older. Exposure assessment The exposure assessment involved a description of the likelihood, magnitude, frequency and duration of exposure to COPC as well as the identification of the possible exposure routes. The most likely exposures were: long-term lowlevel exposure, and direct contact (i.e., ingestion, dermal absorption, inhalation of suspended particulate matter). The maximum contaminant concentrations of COPC identified at the site were used to estimate the magnitude of receptor exposure, or the exposure dose. The bioavailability of COPC, defined (in part) as the fraction of the exposure dose that absorbs into the body and reaches the blood stream of human receptors, was considered 100% in cases of oral and inhalatory exposure routes. The bioavailability factor of dermal absorption was applied for consideration of the dermal route of exposure. Realistic recreational exposure scenarios reflective of site-specific human 56 | July 2008

activity patterns at the site were applied to provide an overall evaluation of potential risk of exposure to COPC at the proposed development. It was assumed that an infant would visit the site 12 hours/week, for 32 weeks of the year (mid March to mid November), a toddler would visit the site 17 hours/week, 32 weeks of the year for 4.5 years and a child would visit the site 20 hours/week, 32 weeks of the year for 7 years. An exposure duration of 12 years was used to assess potential risk to children exposed to COPC at the site. For adults, it was assumed they would visit the site an average of 19.25 hours/week, 32 weeks of the year (mid March to mid November; when the ground is not likely to be frozen), over a lifetime of 70 years. Construction/utility workers were assumed to be at the site an average of 5 days/week, (40 hours/week), 28 weeks/year for 0.5 years (the duration of time assumed for site development). Dose response assessment The nature of the relationship between the received dose (estimated daily intake) and the probability of an adverse biological response was evaluated in the dose-response step. Estimated daily intakes (EDIs) through each route of exposure were calculated individually for each COPC. EDIs are an approximation of the amount of COPC potentially absorbed into the body through each of the dermal (skin), oral (gastrointestinal) and respiratory (respiratory system) routes of exposure. EDIs were based on maximum measured COPC concentrations and calculated using standard mathematical
formulas commonly used in the risk assessment process and established by Health Canada. Toxicity benchmarks, defined as the amount of contaminant exposure that can occur without adverse health effects, were also identified in this step. Toxicity benchmarks are generally determined from exposure data obtained from controlled animal and human laboratory tests and/or epidemiological studies. The toxicity benchmarks used in this study were the most restrictive available published values from Health Canada and the USEPA. Toxicity benchmarks are expressed as either Reference Doses (RfD) and/or Slope Factors (SF). RfD are determined for threshold toxicants (non-carcinogenic) and SF are determined for nonthreshold toxicants (health effect is considered cancer or a heritable mutation). Toxicity benchmarks were applied with the calculated EDI to mathematical models to derive a risk factor for each COPC. The calculated risk factor for each COPC was ultimately used to characterize potential risk associated with exposure to COPC at the site. Risk characterization Risk characterization was the final step in the risk assessment process and involved a determination of a numerical estimation of risk, and the integration of all information gathered through hazard identification, dose response and exposure assessment to estimate human health risk associated with exposure to contaminants at the development site. Health risks were estimated numerically by comparing EDIs to acceptable toxicity benchmarks. Both EDI and toxicity benchmarks
Environmental Science & Engineering Magazine
Redevelopment were applied to mathematical models for evaluating risk for both non-threshold (i.e., non-carcinogenic) and threshold (i.e., carcinogenic) toxicants. For threshold toxicants, a mathematical approach, the reference dose-hazard quotient methodology, was used to quantitatively assess the potential hazards presented by exposure. In this methodology, following the Health Canada and USEPA HHRA Guidelines, the human risk estimate was expressed as a Hazard Quotient (HQ). For threshold toxicants, calculated EDIs were expressed as a ratio of acceptable daily intakes or reference doses (RfD). A HQ of 0.2 for any threshold toxicant COPC was used to assess acceptable exposure from each individual pathway and was utilized as reference point. Thus, for threshold response contaminants, a HQ that was less than or equal to 0.2 indicated that the potential exposure was within the degree of exposure that was considered acceptable or â€œsafeâ€?. For carcinogenic contaminants, risk was calculated by multiplying the estimated intake by the appropriate slope
factor (SF). The estimate corresponds to an incremental risk of an individual developing cancer over a lifetime as a result of exposure. The calculated risk was then compared to an acceptable benchmark. Target levels of acceptable cancer risk (acceptable benchmarks) vary depending on the regulatory agency, but are usually in the range of 1 in 100,000 (i.e., 1 extra cancer death per 100,000 people exposed to a contaminant over their lifetime) to 1 in 1,000,000 ( i.e., 1 extra cancer death per 1 million people exposed to a contaminant over their lifetime). A risk level of 1 x 10 -5, which is the benchmark level recommended by Health Canada, was used in the risk assessment for comparison to calculated risk values. Cancer risk levels that were less than 1 x 10-5 were viewed as acceptable. The HQs for all COPC were well below the target value for all receptors (i.e., 0.2). The risk level calculated for all non-threshold COPC also fell well below the target value (1.0 x 10-5) for carcinogenic effects. In other words, the overall assessment strongly suggested that there was no significant health risk
posed by non-carcinogenic and/or carcinogenic COPC at the proposed site. Summary The results of the human health risk assessment indicated that exposure to the maximum concentrations of COPC identified at the site would not result in adverse human health effects to park users. Further, the magnitude and distribution of COPCs at the site were such that extensive remediation was not required, and no significant restrictions on the proposed use of the site were recommended. Construction at the site commenced in 2007 following extensive public review, as well as regulatory approval and permitting by various agencies including Health Canada and Saskatchewan Environment.

CANECT REPORT CANECT 2008 featured over 60 presenters he Canadian Environmental Conference and Tradeshow (CANECT) took place April 21-22, 2008, at the Metro Toronto Convention Centre. The event featured over 60 presenters from Canada’s leading law firms, trainers, consultants and environmental managers and practitioners. It covered a wide range of environmental protection issues. One session discussed several new federal and provincial regulations which environmental professionals have to understand to make sure their companies remain compliant. Another key challenge for environmental and operations managers is to establish strategies and practices to meet stricter GHG and air emissions standards, and these topics were also covered. Ontario’s new Spill Reporting and Contingency Planning Regulations and Environmental Penalties Regulations formed an important focus of another CANECT course. These new provisions impose individual liability on corporate officers who fail to prevent spills or breaches of approval conditions. Mandatory minimum fines and environmental penalties of up to $100,000 per day will apply for companies and individuals convicted of discharge offences. Along with spills, Certificate of Approval (CofA) violations are one of the most common triggers of environmental investigations and inspections. A new course this year provided registrants with a fundamental introduction to strategies for effectively managing and updating environmental permits and Certificates of Approval and tips for communicating with the Ontario Ministry of the Environment to keep their organizations onside. Equally challenging are new assessment and remediation requirements dealing with the opportunities of dealing with contaminated land. Consultants, lawyers, company managers and developers were updated on how to ensure they are up to date with the new requirements and their implications. New waste regulations, coupled with ongoing product stewardship initiatives introduced under the Waste Diversion Act, formed the focus of another course. Along with increased enforcement of Ontario’s 3Rs regulations, they challenge industry, institutions and managers to take responsibility for waste or pay the price. Responding professionally to a call by MOE inspectors and investigators is vital if companies are to avoid the costly pitfalls that too often result from uncontrolled investigations. One CANECT course helped prepare delegates to respond to MOE inquiries. They learned how to manage records and reports in order to limit ‘fishing’ expeditions while being able to offer full cooperation. Another course discussed Canada’s new ‘post-Walkerton’ regulatory regime for water and wastewater which is now arguably the toughest in the world. Delegates were told that the new legislation of 2006/7 is only the beginning, with new Wastewater Effluent Regulations under a new federal Fisheries Act coming. Additionally, a new CCME Canada-wide municipal model sewer-use bylaw threatens to introduce the most stringent limits yet on industrial discharges. A verifiable Environmental Management System (EMS) is one of the key ways that organizations can prove their environmental due diligence. One CANECT session helped delegates ensure they have a system in place with which to confidently manage their organization’s current and future environmental responsibilities. Launched in 1992, CANECT attracts senior people responsible for environmental engineering, regulations and compliance issues. It was co-organized by Environmental Science and Engineering Magazine and Canadian Environmental Regulation and Compliance News. Golder Associates was one of the event sponsors.
CANECT 2009 will be held April 20 -21 at the same location as this year and it will again be co-located with the Health & Safety Canada show. For further information, please contact Denise Simpson, Tel: 905-727-4666, or visit www.canect.net 60 | July 2008

BC hopes its new Climate Action Plan will dramatically reduce GHG emissions ritish Columbia’s Climate Action Plan outlines comprehensive strategies and initiatives that will help it reach its greenhouse gas emission reduction target by 33 per cent by 2020. It provides information on the many ways British Columbians can reduce energy consumption and save money while reducing their greenhouse gas emissions. The plan commits a total of $28.5 million over three years to a variety of pollution reduction initiatives to reduce greenhouse gas emissions through programs such as the new LiveSmart BC home retrofit incentives, which are designed to reward smart choices that save energy, water, fuel, time and money. It also outlines how British Columbia’s business sector can capitalize on an emerging and rapidly growing global green economy. The plan, which contains GHG emissions modeling by M.K. Jaccard and Associates Inc., uses conservative esti-

BC Premier Gordon Campbell (second from right) helped announce the province's new bioenergy strategy, which is part of its Climate Action Plan.
mates to outline how emissions will be reduced in each of the province’s major sectors. For example, the modeling is based on the price of oil averaging US $85 a barrel through 2020, a forecast that is significantly below the current price of oil. It is also based on the assumption that the revenue-neutral carbon tax does not increase beyond 2012, and assumes the use of existing and
available technologies. The plan addresses climate action in four key areas: entrenching greenhouse gas reduction targets in law; taking targeted action in all sectors of the BC economy; taking steps to help British Columbians adapt to the realities of climate change and educating and engaging British Columbians on climate action. The plan’s wide range of initiatives include $1.8 billion in innovative tax cuts funded by the revenue-neutral carbon tax, a new carbon emission cap and trade system and investments in emerging green technologies. The plan also includes the expansion of Citizens’ Conservation Councils to help build a network of grassroots climate actions in communities across the province. It describes province-wide actions that have been taken to date, along with strategies specific to seven sectors. For more information, visit www.gov.bc.ca.

NEWS House of Commons adopts NDP leader Jack Layton’s Kyoto-Plus bill With the recent passage of NDP Leader Jack Layton’s private member’s bill, The Climate Change Accountability Act (Bill C-377), Canada’s House of Commons has become the first elected chamber in the world to adopt science-based targets to reduce greenhouse gas emissions by 80 per cent, from 1990 levels, by 2050. “This is a world first,” said Mr. Layton. “Our legislation sets tough but achievable targets that will ensure Canada does its share to avoid the dangerous two-degree increase in average global temperature that scientists warn us about.” To ensure Canada meets long-term pollution reduction targets, short- and medium-term targets are also enshrined in the law. The bill sets an interim target of 25 per cent reduction in greenhouse gases by 2020 and requires progress reports from the government every five years. “These are targets endorsed by world leaders, enshrined in legislation,” said Mr. Layton.
Newalta opens new haz-waste processing operation
At its Toronto facility, Newalta has created what it says is one of the most sophisticated labpack processing operations in North America. Using an automated process that improves safety and reduces the amount of operator exposure and physical handling required of labpack wastes, the operation can handle up to 25,000 labpacks per year and will serve customers throughout Ontario and Quebec. “Labpacks” are small quantities or containers of chemical waste, consolidated and specially packaged in drums, typically from the pharmaceutical industry, laboratories, research facilities, institutions and industrial businesses. The new “depacking” process in80 | July 2008
volves the use of two separate monitored reaction vessels for organic and inorganic waste, the inorganic portion of which is temperature-controlled. The operation also incorporates an automated crusher and plastics shredder to manage the original labpack waste containers, which provides a physical barrier to protect technicians from the reaction area. To minimize air emissions from collection vessels, process vapours are handled through either activated carbon absorbers or a two-stage scrubbing system. Process materials are reused or recycled whenever possible. Smaller portions of the waste material may be sent off-site for alternative safe disposal. www.newalta.com
Rick Wilson retiring as Executive Director of CAEAL
At the 2004 CAEAL AGM. Rick receives formal recognition of his leadership skills from his colleagues and team. Russ Calow (left) presents Rick (right) with a framed copy of the success stories poster, “The Essence of Leadership.”
Richard (Rick) Garth Wilson, PhD, will be retiring as Executive Director of the Canadian Association for Environmental Analytical Laboratories Inc. (CAEAL) this coming October. Rick was appointed the association’s Executive Director in August 1994. In 2001, he was called as a witness before the Walkerton Commission of Inquiry. In Part II of his report, Justice O’Connor praised CAEAL for its everyday achievements: “I heard evidence about the organization of the accreditation program and the types of review that CAEAL auditors carry out. I was impressed by the thoroughness of the verification process and the capacity to identify areas for improvement at individual laboratories. Although a quality assurance program adds time, effort, and cost to laboratory operations, the improvements in reliability,
validity, and record-keeping more than offset the increased expenditure. As such, drinking water testing should be performed only by accredited laboratories, as currently required under Ontario Regulation 459/00.” “For the nearly 200 people who work or volunteer for CAEAL, Rick has provided a workplace environment where we can attempt to do the right thing every day. And we have always had his permission to fail,” said Ned Gravel, CAEAL’s Manager of Quality and Training.
WEF weighs in on California biosolids litigation Recently, the Water Environment Federation (WEF) filed an amicus curiae (friend of the court) brief in the Kern County, California biosolids litigation. The brief was filed with the US Court of Appeals for the Ninth Circuit and supports the position of three southern California public agencies that operate land application programs in Kern County and that are asking the Appeals Court to maintain a district court judge’s ruling that allows these programs to continue. WEF has a long-standing position in support of biosolids recycling, including support for land application. The outcome of the Kern County case has the potential to have a significant impact on biosolids programs in every state, not just the Ninth Circuit, because this will be the first appellate decision on whether biosolids bans are legal under the federal Constitution.

Edmonton to be site of world’s first industrial scale municipal waste-to-ethanol facility Edmonton will be home to the world’s first industrial scale facility to produce biofuels from municipal solid waste, having signed a 25-year agreement with GreenField Ethanol, Canada’s largest ethanol producer and Enerkem, a biofuels technology company. The $70 million biofuels facility will initially produce 36
million litres of biofuels per year and reduce Alberta’s carbon dioxide footprint by more than 6 million tonnes over the next 25 years - the equivalent of removing 12,000 cars off the road every year. The City of Edmonton and the Government of Alberta through the Alberta Energy Research Institute (AERI) are contributing $20 million to the facility. The City of Edmonton will also contribute $50 million to a related processing facility and research facility. AERI’s total contribution to all the components is $29 million. This new facility is said to be a first for both the biofuels and waste management industries, as is the agreement between a large urban centre and a biofuel producer to turn municipal waste into ethanol.
Mercury levels in BC salmon shown to be below guidelines A new study published in Environmental Toxicology and Chemistry has found that levels of mercury and trace metals in both wild and farmed salmon from British Columbia are significantly below
health guidelines. Mercury levels tested in both farmed and wild salmon were well below consumption guidelines set by Health Canada. Maximum concentrations of other metals were also well below guidelines. Farmed salmon did not have significantly higher concentrations of arsenic, cobalt, copper, or cadmium than wild salmon. In fact, mercury concentrations in the flesh of wild salmon were threefold higher, probably because farmed fish have such rapid growth cycles, resulting in growth dilution. Compared to other foodstuffs, total mercury was found to be slightly higher in wild or farmed salmon than in chicken, beef, or pork but comparable to fruit, vegetables, honey, and eggs. Levels of other trace elements were lower in salmon than in other foodstuffs, and average dietary intake of mercury and trace metals from salmon remains low (0.05%–32%) compared to meat, poultry, fruit, and vegetables (68%–99%).

In a precedent-setting decision that will impact air, water and waste decisions throughout the province, the Ontario Divisional Court has ruled that a citizenled appeal of Lafarge Canada's plan to burn tires, plastics, bone meal and other waste in Bath, Ontario, will go forward. The Court rejected a last-ditch effort by the Ministry of the Environment and Lafarge to shut down an Environmental Review Tribunal hearing. Lake Ontario Waterkeeper & Gord Downie, Clean Air Bath, Loyalist Environmental Coalition, and members of The Tragically Hip won the right to appeal licences for air emissions and a waste site last year. The groups cited concerns about potential air pollution, water contamination, and human health impacts. The Ontario Divisional Court decided to hear the case after determining "the allegation that the tribunal erred in applying the test for leave is a matter of significant importance in this and other cases." The Court ruled in favour of Waterkeeper & Gord Downie and Loyalist Environmental Coalition on every issue. Its precedent-setting decision confirms the public's right to participate fully in environmental decision-making. It requires the Ministry of the Environment to consider the cumulative environmental effects of issuing an approval before doing so and to apply the precautionary principle to such decisions.
Research provides clarity on pathogen growth in dewatered biosolids The Water Environment Research Foundation has released a report on pathogens in anaerobically digested biosolids and the performance of various digester/dewatering combinations. The report is a follow-up to earlier testing that showed an increase of some indicator organisms immediately after dewatering at some facilities. The new work found no evidence of a corresponding increase of diseasecausing bacteria in most processes. Research looked especially at Salmonella, since it is the most reliably measured pathogenic bacteria in biosolids. WERF and its research partners iniEnvironmental Science & Engineering Magazine
NEWS tially undertook this study in response to reports of increases in indicator organism counts following anaerobic digestion and dewatering at a few wastewater treatment facilities. The most recent research verified increases in indicator organisms following digestion and dewatering. But Salmonella was not found in biosolids following themophilic digestion, or dewatering by either centrifugation or filter pressing. Regrowth of Salmonella was observed in stored dewatered biosolids after Class B mesophilic digestion, a process which is not designed to destroy all pathogens. However, concentrations decreased over time when the biosolids were stored. The full results are available in the study report, Phase II and III: Evaluation of Bacterial Pathogen and Indicator Densities after Dewatering of Anaerobically Digested Biosolids. www.werf.org

Understanding the effects of carbon sequestration on groundwater The AWWA Research Foundation (AWWARF) has announced a new study to investigate the potential effect of underground carbon sequestration on groundwater resources. Currently undergoing examination as a method for reducing greenhouse gas emissions, carbon sequestration entails separating carbon dioxide (CO2) from other emissions and injecting it into deep, underground natural storage areas such as oil and gas reservoirs, saline aquifers, or coal seams. The study will look specifically at the potential impacts that carbon sequestration may have on underground water sources. “Previous and ongoing research on carbon sequestration largely focuses on long-term efficiency for containing carbon emissions, without consideration of potential impacts on the water supply,” said Robert C. Renner, AWWARF executive director. “CO2 injected into underground formations could potentially leak into overlying water supplies, with associated implications for groundwater quality, or it may displace fresh water with saline water in aquifers.

A province-wide ban on the sale and use of pesticides is one step closer today with the passage of the Cosmetic Pesticides Ban Act by the Ontario legislature. Over the summer, the government will consult on the specifics of the ban, including: products to be banned from sale; ingredients to be banned from use; rules around exceptions for agriculture, forestry and golf courses, with conditions. The province will also develop rules for other exceptions, such as fighting West Nile virus, for example, and other health or safety issues. Once the ban is fully in place, it will take the place of existing municipal pesticide by-laws, bringing consistency across the province and protecting Ontarians regardless of where they live. The provincial law, unlike municipal by-laws, bans the sale of cosmetic pesticides, not just their use. It also sets out the rules for the transportation, storage and disposal of pesticides, requirements that municipal by-laws cannot control. The ban should take effect in spring 2009.
Lawn fertilizer restrictions for Manitoba Manitoba is the first province in Canada to enact legislation that restricts the application of lawn fertilizers containing phosphorus in residential areas, a key step in reducing the flow of excess nutriEnvironmental Science & Engineering Magazine
NEWS ents into provincial waterways. Following public consultations last fall, the province will restrict the use of lawn fertilizer containing more than one per cent phosphorus by the beginning of 2009. Lawn fertilizers currently sold in Manitoba have phosphorus content as high as 20 per cent. Manitoba’s regulatory change to control fertilizer applications is modeled on similar regulations adopted by Minnesota in 2005. Minnesota’s controls resulted in a nearly 50 per cent reduction in phosphorus being applied in fertilizers to lawns in residential areas. As Manitoba soil already has high phosphorus concentrations, fertilizer containing phosphorus is in most instances not necessary to maintain a healthy lawn. Applications of fertilizers containing phosphorus would be permitted on a short-term basis for new lawns. Following the Minnesota model, the province will evaluate the effectiveness of the restrictions one year after their implementation. Introducing restrictions on lawn fertilizers containing phosphorus follows key recommendations of the Lake Winnipeg Stewardship Board’s final report.

Saskatchewan Premier Brad Wall also called on his fellow premiers and territorial leaders to support an expanded national effort in the area of crop science research, as Canada continues to experience the effects of climate change. "Saskatchewan has historically led in crop science research, and with national support we need again to lead in this area in the future," he said. "Our growing season is now three weeks longer than it was in the 1960s, temperatures are warmer, and we need to invest in crop science.â€? In the forestry sector, Saskatchewan has asked for a national strategy on climate change adaptation, including managing research on the spread of the mountain pine beetle.
Pottersburg PCB storage site to be decommissioned In March 2008, the Ontario government announced funding for the safe destruction of polychlorinated biphenyls (PCBs) at the Pottersburg PCB storage facility as part of its commitment to reduce toxins. The Pottersburg site on Clarke Road in London is a closed, controlled, secure containment facility, owned and operated by the Ontario Ministry of the Environment (MOE). The facility was initially created by Westinghouse Canada in 1984 by order of the MOE to contain PCBcontaminated material cleaned up from Environmental Science & Engineering Magazine
NEWS their property. The containment site was later purchased by the MOE in 1985 to store PCB-contaminated soil originating from a number of other industrial properties, as well as sediments cleaned up from Pottersburg Creek and Walker Drain in London. There are 35,500 cubic metres (78,000 tonnes) currently stored on the site. The government says that timing of this clean-up is now ideal as there are safe and effective methods for permanently destroying PCBs, for significantly less cost than 10 years ago. There are no known health risks associated with the ongoing storage of the PCBs at this secured site. The facility consists of four containment cells lined with a non-permeable synthetic liner and about 24 inches of clay. The lined cells are surrounded by a sand/gravel leak detection zone contained within a secondary seal of clay. Removal and destruction of the PCB waste is scheduled to be completed by the end of 2009. The site’s return to industrial use standards is scheduled for completion by the end of 2010.

Kitimat-Summit Lake pipeline project approved Pacific Trail Pipelines Limited Partnership has received an environmental assessment (EA) certificate for their $1.1 billion Kitimat-Summit Lake Pipeline project. BC Environment Minister Barry Penner and Energy, Mines and Petroleum Resources Minister Richard Neufeld made their decision to grant the EA certificate, after considering a comprehensive review led by BC’s Environmental Assessment Office. The project consists of the construction and operation of a 463-kilometre, 91-centimetre diameter buried pipe between Kitimat and Summit Lake, including one new compressor station along the proposed system that will connect with the existing Pacific Northern Gas natural gas pipeline and convey natural gas from the proposed Kitimat Liquefied Natural Gas (KLNG) terminal to the Spectra Energy gas transmission system. Before the project may proceed, the proponent must also obtain the necessary provincial and federal permits and aucontinued overleaf... www.esemag.com

NEWS thorizations. The provincial environmental assessment certificate contains numerous commitments that the proponent must implement throughout various stages of the project. Key commitments include: • Assess the erosion potential of soils and implement adequate erosion controls. • Mitigate potential loss or degradation of instream fish habitat. • Monitor water quality in the Morice Water Management Area. • Develop a hydrostatic test plan to manage discharge water quality, temperature and withdrawal volumes. • Mitigate potential effects to wildlife and wildlife habitat. • Manage public access into previously inaccessible areas.
NWT developing water strategy The Department of Environment and Natural Resources (ENR), in collaboration with Indian and Northern Affairs Canada (INAC) NWT Regional office, is seeking input into the development of a
Northwest Territories (NWT) Water Resources Management Strategy to address the current and potential challenges to water resources management. “Wetlands, deltas and waterflows throughout northern Alberta and the southern Northwest Territories are changing, and the increased demand for energy and development requires that our concerns about water are heard and acted upon”, said ENR Minister Michael Miltenberger. “A Water Resources Management Strategy should help us ensure that development activities do not substantially alter waters that flow into, or through, the NWT in quality or quantity.” A discussion paper entitled Northern Voices, Northern Waters: Towards A Water Resources Management Strategy for the NWT presents a sense of what the future management of NWT waters could be. It sets out both the form of a future Water Resources Management Strategy and the kinds of actions that could be undertaken to develop and implement a strategy. NWT residents, Aboriginal governments and organizations, and interested stakeholders will all have the opportunity to contribute to the development of a strat-

egy. An NWT Water Resources Management Strategy will incorporate traditional knowledge and recognize and respect Aboriginal and Treaty rights, land claim agreements and self-government agreements. Consultations with Aboriginal governments and interested stakeholders will continue into the fall of 2008 and a final strategy will be completed in March 2009.
BC develops water sustainability plan “More than 40 actions and targets in a new government-wide plan will help all sectors, communities and British Columbians keep the province’s water healthy and secure, now and in the future,” says Environment Minister Barry Penner. Living Water Smart is a blueprint for cultural, environmental, industrial, community and agricultural changes that will help safeguard the province’s water resources into the future. Drawing on a variety of policy measures, including planning, regulatory change, education, and incentives like economic instruments and rewards, the plan commits to new actions and builds on existing efforts to protect and keep BC’s water healthy and secure. BC’s economy and industry continue to grow, and its population is expected to increase by another 1.4 million people in the next 25 years. In some areas, like the Okanagan and Gulf Islands, seasonal water shortages are already challenging community water systems, and the fish and aquatic ecosystems that depend on these systems for survival. Climate change and its related effects, like the mountain pine beetle and changing water cycles, are also adding to the pressures on fresh waters. www.livingwatersmart.ca

Reducing stormwater damage to streams in urbanizing areas When an area is changing from rural to urban, city planners try to measure the impact of development on a whole host of "quality of life" factors. What will happen to traffic patterns? Will the community need new schools? Who will provide water and sewer services? With how much capacity? These are measurable questions. On the other hand, the pressure of urbanization on ecological factors has historically been tougher to gauge, and so researchers are developing objective and reliable measurements that cities can use in planning. Urbanization has a profound effect on fish and other aquatic life in rivers and streams. Stormwater runoff reacts differently when land use changes, and can make drastic changes to the aquatic environments of the newly urban streams. One solution is to find a system that city planners can use to measure, in advance, the impact of land changes on the health of the watershed. A group of researchers set out to develop a systematic approach that could evaluate the impacts of land use patterns and stormwater management strategies on the health of streams in developing areas. The research, funded and managed by the Water Environment Research Foundation (WERF), resulted in a report entitled Protocols for Studying Wet Weather Impacts and Urbanization Patterns. The protocols, designed for urban stormwater management agencies, could prevent any severe ecological deterioration that threatens urban streams. The main protocol is an eight-step process that integrates data collection and analysis with mathematical modeling of runoff 90 | July 2008
from existing and planned urban development. The results determine how biologic health responds to the urbanization. In addition to the full protocol, the report also provides a simpler process that does not require extensive data collection. www.werf.org
Drinking water safety initiative unveiled Charlene Johnson, Minister of Environment and Conservation, and Dave Denine, Minister of Municipal Affairs, recently announced the Drinking Water Safety Initiative for Newfoundland and Labrador. The initiative will develop a comprehensive overview of drinking water quality issues in municipalities and communities in parts of the province, and develop a sustainable plan of action to deal with those issues. Building on the principles of the Multi-Barrier Strategic Action Plan, the Drinking Water Safety Initiative outlines several options to improve upon drinking water safety in the province and is based on a comprehensive evaluation of every public water supply in the province. A significant component of this initiative includes the installation of Potable Water Dispensing Units. These units are small scale water treatment plants from which the residents of small communities are provided high quality drinking water. To implement the Drinking Water Safety Initiative, $2.9 million has been allocated to the Department of Environment and Conservation over the next three years. In Budget 2008, $1.025 million was allocated, and $925,000 will be spent in each of the following two years. A further $6 million annually within the Department of Municipal Affairs will be targeted towards investment in infrastructure to provide clean, safe drinking water, including potable water dispensing systems.
Alberta recognizes companies for environmental excellence Companies that model environmental excellence in Alberta are being recognized through EnviroVista, a voluntary program among industry, municipal governments and the Alberta government to promote enhanced environmental per-
formance. This year, Alberta Newsprint Company in Whitecourt joins Alberta Envirofuels Inc. Isooctane Plant in Edmonton as an EnviroVista champion. Envirofuels Inc. was the first facility in Alberta to become an EnviroVista champion and is now in its second year of a 10-year commitment. Alberta Newsprint Company is a pulp and paper mill located in Whitecourt, and an EnviroVista leader since 2006. Alberta Newsprint started operating in 1990 and produces more than 269,000 metric tonnes of product each year. It is Albertaâ€™s first paper mill, and uses state-of-the-art environmental technology. The EnviroVista program has two participation categories - Leader and Champion. Leaders have at least five years of exemplary emissions performance, an audited environmental management system and no Alberta Environment enforcement action in the past five years. These criteria are required for each year that companies remain in the program. To become an EnviroVista champion, a facility has to meet the leader criteria and commit to further environmental enhancements under a 10-year stewardship agreement. Any industrial or municipal facility licensed under Alberta's Environmental Protection and Enhancement Act is eligible to apply for the EnviroVista program. www.environment.alberta.ca
