Comment by Steve Davey

To compete, or not compete - that is the question astewater operators play a vital role in running what are essentially $10-200 million 24/7 processing plants, that ensure both public health and environmental protection. As such, it would stand to reason that owners of these plants (with the inherent legal liability that entails), would want their operators to be experienced, qualified, highly motivated, and resourceful. Recognizing this need, the Water Environment Federation - and many of its regional Canadian associations - launched annual Operations Challenge competitions in the early 1990s. Having been President of the Water Environment Association of Ontario (WEAO) and the Ontario Pollution Control Equipment Association, I was well aware of the logistics and financial planning needed to make these annual competitions a reality. However, it was not until listening to a presentation by Ian Smith, from the City of Toronto, to fellow members of the Ontario Select Society of Sanitary Sludge Shovellors, that I truly came to appreciate how valuable they can be to participating operators. In his presentation, Ian described the Events that comprise a Challenge and how extremely well-educated, experienced, prepared and motivated contestants and their coaches need to be. For the Process Event, each team has 25 minutes to complete 42 multiple choice questions. For WEAO’s 2011 Laboratory Event, teams had to perform an E. coli membrane filtration analysis, using proper aseptic techniques; follow the Hach mColiblue24 procedure consistent with Standard Methods 9222B; perform 17 separate procedures, many of which are repeated for six samples; calculate E. coli colonies per 100 ml; answer a variety of quiz questions. A timed activity, the Collection Event involves connecting a 4-inch PVC lateral sewer to an existing 8-inch PVC sewer pipe, while in service, and then programming an automatic sampler. The Safety Event uses a specially built platform to simulate a rescue situation, within the confined space of a manhole. 6 | Summer 2011

The Flangetastic Four competing at the 2011 WEAO Operations Challenge,

Each team “finds” an unconscious coworker at the bottom of a “lift station”. As this rescue effort begins, another coworker has a heart attack, leaving remaining team members to cope. For the Pump Maintenance Event, teams have to take a faulty submersible pump and a submersible mixer out of service, perform and document the required services to repair them, then place the units back into service. The first and second place teams in a regional Challenge are then eligible to participate in the North America-wide Operations Challenge, held by the Water Environment Federation at WEFTEC. Many Operations Challenge participants have explained to me that preparing for these events, meant they had to learn much more than they would have otherwise had to for day-to-day work. Also, there are the extra benefits of developing a face-to-face network of colleagues from other plants and regions, and sharing knowledge and experience. Many have commented that winning their regional event, finally allowed them to visit WEFTEC. While there, for the first time in their careers, they could see full scale pumps, valves, sludge dewatering equipment, etc., used throughout the industry. Also, they were able to learn more about monitoring and instrumentation products, that improve plant operations and efficiency. Of benefit to their co-workers and managers is that they

bring this experience, knowledge, confidence and enthusiasm back with them. Also, according to Ian, “participating, helping organize and judging Operations Challenges is like taking a practical management course, which has helped many assume more senior positions within their own organizations.” Unfortunately, too many Canadian municipal managers no longer see value in supporting their plant operators, who may want to compete in Operations Challenges. Consequently, many operators can now only participate if they cover the expenses personally and take vacation time off to attend. This is indeed a short sighted “bean counter” mentality. Wastewater plants are biologically, mechanically, and electronically complicated to run. As evidenced by numerous and often costly fines levied for discharge violations, they break down even when run by highly qualified and experienced staff. Surely, encouraging operators to exceed their current qualifications, by supporting professional development events, like the Operations Challenge, is money well spent.

Water Supply and Management

Statscan researches Canada’s freshwater supply and demand he Human Activity and the Environment publications bring together a collection of environmental statistics from many sources, and paint a statistical portrait of Canada’s environment. Special emphasis is given to the relationship of human activity to air, water, soil, plants and animals. For “Freshwater supply and demand in Canada” new research done within Statistics Canada is incorporated with information from other sources, including other federal government departments, international bodies and scientific journals. Water supply Canada’s average annual renewable freshwater supply, or water yield, is 3,472 km3. To put this into perspective, this amounts to almost as much water as there is in Lake Huron, which contains 3,540 km3. This abundance in water yield is distributed unequally across the country. With an average annual water yield per unit area of 1.54 m3/m2, the Pacific Coastal drainage region has the highest. It is followed by the Newfoundland and Labrador and the Maritime Coastal drainage regions, which have average annual yields per unit area of 0.86 m3/m2 and 0.85 m3/m2 respectively. Drainage regions in the Prairies and north of the Prairies produce the least water, with yields between 0.02 and 0.07 m3/m2. The southern part of Canada, where 98% of the population is located, is responsible for 38% of the water yield or 22,661 m3 of renewable freshwater per capita. In the North, water yield per capita is 185 times greater, or 4,193,014 m3. Average annual water yield per unit area for the Prairies is 0.05 m3/m2, less than that for either Australia or South Africa. This is equivalent to 12% of the yield of the Great Lakes drainage region, 6% of the yield of the Maritime Coastal drainage region and only 3% of the Pacific Coastal drainage region. Brazil, which has the highest total water yield of any country in the world, provides 43,756 m3 of water per person per year, 40% of the almost 110,000 m3

In 2005, an estimated 42 km3 of water were withdrawn from the environment and used in household and economic activities in Canada.

that is annually available per person in Canada. While total water yield is comparable between the United States and Canada, the amount of renewable freshwater per American is only 9.1% of that per Canadian, because the United States has a much larger population. Trends in water supply From 1971 to 2004, water yield in Southern Canada decreased an average of 3.5 km3 per year, which is equivalent to an overall loss of 8.5% of the water yield over this time period. This is almost as much as the 3.8 km3 of water that is supplied to the residential population of Canada in a year. For most of the country the bulk of the water yield is produced in April, May and June, as snow, ice melt, and precipitation increases. In the North, this peak occurs in late spring and early summer. In the South, water yield is highest in the spring. As spring turns into summer, yield declines and demand for water related to human activity increases. Water use In 2005, an estimated 42 km3 of water were withdrawn from the environment and used in household and economic activities in Canada. About 14% of this water flowed through the public utility water system, while about 86% was ex-

tracted from the environment, directly by the end user. More than 90% of the water that was withdrawn went to support economic activity, and about 9% was used directly by the residential sector. The residential sector used 56% of the water that was supplied by the public utility water system. Thermal-electric power generation was the sector that used the most water overall, by a considerable margin. It is estimated that 25% of Canadians rely on groundwater as a source of drinking water. This varies depending on the region of the country: the population in the Saint John–St. Croix, New Brunswick, drainage region is the most reliant on groundwater, whereas the population in the South Saskatchewan drainage region is the least. The agricultural sector was responsible for 4.6% (almost 2 km3) of total water withdrawals in 2005. Most of this water was used to irrigate crops, with 16% going to support livestock production. In 2005, precipitation that supported crop growth was roughly twice the volume of water that was withdrawn annually by all sectors of the economy. Canada is one of the largest producers of hydro-electricity in the world, and the volume of water involved is many times larger than all other uses combined. In 2005, hydro-electric generation in Canada made use of approximately 3 trillion m3 of water - more than 100 times the volume of water used by the thermalelectric power generation sector, and just over 70 times the total volume of all water used in Canada in 2005. More water is embedded in forest products than food. When precipitation was included, the production of exported lumber, wood pulp, paper, and other forest products required seven times more water than the production of exported agricultural commodities. In 2005, total water withdrawals in Canada amounted to 1.2% of the average annual renewable water resources. For more information, visit www.statcan.gc.ca/start-debut-eng.html

Cover Story

Cranbrook BC upgrades its wastewater spray irrigation system By Peter Davey rought in northern China, floods in both Australia and Canada, and wildfires in Russia, have had disastrous effects on global wheat production, and caused prices to jump by nearly 50% recently. This has had a profound effect on government budgets in Developing Nations and on the standard of living of their citizens. Agriculture consumes approximately 70% of the world’s water supply. Rapid urbanization and shifting diets in increasingly developed countries will constrict water allocated to agriculture, while demanding more output. Here’s why. It takes about 1,500 litres of water to produce 1kg of wheat, and about 16,000 litres to produce 1 kg of beef. Increasingly, meat is becoming a larger part of more people’s diets. While global population growth is expected to hold at 1% annually, cereal production must grow by 1.5% to feed more people and more livestock. Consequently, by 2030, it is estimated that farmers will need 45% more water. Irrigated pasture is able to support far more cattle than natural pasture. While native grass supports one calf/cow pair per 10 acres, irrigation allows for 60 pairs per 10 acres. With proper guidelines and public support, effluent spray irrigation can be a viable option to quench farmers’ needs. The Cranbrook City Farm, in Cranbrook, British Columbia, has been operating as a hay/alfalfa farm and cattle pasture since 1978. Producing 3,600 tonnes of hay and partially supporting 1,500 head of cattle, the City Farm is also a wildlife sanctuary and popular recreation area. Covering 2,200 acres, 1,800 of which are pasture, it is the largest among 70 similar operations across western Canada. In 1974, the City of Cranbrook was ordered by the BC government to develop an alternate sewage disposal method. Effluent spray irrigation was chosen for cost and economic advantages. With an initial cost of $10.5 million, effluent irrigation was significantly cheaper than the approximately $50 million required for mechanical treatment. The initial facility

included a pump house, pivot irrigation, onsite storage and settling ponds, with available capacity for 27,000 residents. Raw household sewage, collected through the City’s sanitary sewer system, was carried to a three-lagoon, three-stage, primary treatment site. It was aerated sequentially in these storage lagoons over 30 days. Then, effluent was transferred from settling ponds to two City Farm storage ponds via a pipeline. The storage ponds covered roughly 134 acres, with a 660 million gallon capacity. Effluent was stored and aerated in these ponds for six months, then applied to crop land during the summer months through a pivot irrigation system. In July, 2010, the City, with federal and provincial assistance, broke ground on an extensive wastewater treatment upgrade. This was the result of an Environmental Appeals Board ruling that storage capacity needed to be increased, while the water level in storage pond #2 had to be lowered. The system upgrades consisted of the following: • Adding fine bubble aeration to the treatment lagoons.

• Upgrading pumping station and pipeline systems. • Increasing the aeration capacity in pond #2. • Increasing irrigation pump capacity. • Creation of a third storage pond. • Chemical feed for phosphorus removal. • Constructing an outfall system, including UV disinfection, for discharge into the Kootenay River. Emphasis has been placed on designing the system to meet discharge regulations and future requirements. Major components, including aeration headers, blower pads and piping, have been designed to meet projected requirements for 30 years. Construction of a third storage pond was necessary to meet forecasted growth for the next 20 years. UV disinfection, phosphorus removal and chlorine reduction upgrades are essential in ensuring the system can manage Cranbrook’s growing population, while maintaining effluent quality beneficial for faunal irrigation and possible direct discharge into local waterways. Health concerns As with any waste storage site, leach-

Cover Story ing and other negative impacts must be considered. Concerns over the structural integrity of pond #2 were a large factor in the BC Pollution Control Branch’s ruling. Furthermore, as effluent-watered grasses are consumed by livestock destined for human consumption, it is prudent to stringently monitor effluent quality. Officials state that the effluent applied is “approaching the same quality as that processed by tertiary treatment systems.” Effluent is tested monthly from May to September. In mid-summer during peak application, testing occurs weekly. In addition, foliage tissue is collected and tested. Over 100 parameters are monitored, including fecal coliform, E. coli and enterococcus, as well as key elements, such as nitrogen, phosphorus, sodium, chloride, potassium, etc. Veterinarians report that cattle fed on City Farm forage and hay are comparable to other regional livestock and that no disease or animal health issues were reported. Constraints Effluent spray irrigation systems, similar to the one at the Cranbrook City Farm, offer many advantages. They slake agriculture’s thirst without drawing on additional freshwater, provide beneficial nutrients and minerals to irrigated land, and generate economic gains both directly to participating farmers, and indirectly to recreationalists and businesses involved in farming. However, effluent spray irrigation faces similar drawbacks to other infrastructure projects. “Not in My Backyard” (NIMBY) opposition is a problem which almost every industrial or infrastructure project must overcome. Health complaints attributed to wind turbines continue even though they have been repeatedly shown to have no medical or scientific backing. Similarly, the prospect of having the contents which are flushed down toilets and drains, sprayed near your residence or business is unsettling. Though effluent discharge readings may be in perfect accordance with regulations and harmless in their application, those who reside nearby may think otherwise. Ensuring that proper monitoring and maintenance occurs regularly is vital to a safe and effective treatment plant. But, informing the public of the measures taken, is necessary to ensure their support. www.esemag.com

Wastewater reuse is not a new idea. Ancient Greece is known to have channelled storm and wastewater to nearby orchards and fields, which benefited from the nutrient-rich effluent. As water and fertilizer costs rise with population and food demand, effluent irrigation is an attractive option for wastewater disposal. Cranbrook BC managed to create a lush and highly productive pasture and feed-

stock area in a largely dry and timbered region.

Wastewater Treatment

Containerized MBR wastewater treatment plants for remote mining camps By Choo Sung Tai lobal expansion of the mining industry has brought new challenges, including the need to operate in increasingly remote regions, as well as in accordance with increasingly strict environmental regulations. Wastewater treatment in mining camps is often complicated by the fact that many mines are located in environmentally sensitive areas, where steps must be taken to avoid any adverse effects. Improper disposal of sewage from mining and exploration camps can lead to the pollution of surrounding wetlands. This can result in adverse impacts on wildlife and/or significant long-term damage to the local ecology. In recognition of this, many jurisdictions have tightened regulations governing water discharge from mining and other work camps. Filter Innovations’ FII Remote Biological Treatment (FII RBT) systems have been designed to effectively meet the requirements for sewage treatment and discharge faced by the mining sector. As mines are increasingly being developed in isolated and arid areas, the ability to reuse wastewater is also growing. Due to the considerable expense required to haul water to camps, technologies that can offset water loss by recycling are becoming more and more economically advantageous. FII RBT systems produce treated water suitable for numerous activities, including equipment washdown, dust suppression, secondary toilet flushing and irrigation. FII RBT systems are based on a biological treatment process combined with

an ultrafiltration membrane liquid-solid separation process, based on submerged flat plate membrane technology. The submerged membrane plates have a nominal pore size of 0.04 microns and provide an absolute physical barrier that rejects all suspended solids and pathogens. System design features The systems are modular in design and all of the components are placed in above ground, self-contained, modified high-cube shipping containers. They are pre-assembled, pre-piped and pre-tested to allow for rapid installation and startup. They are also designed to allow modular expandability. An important feature of FII RBT systems is redundancy, which translates into increased reliability. This is accomplished by having duplexed components (e.g., blowers and external pumps), as well as membrane redundancy. The systems are designed for BOD and nutrient removal to levels lower than

any requirement for discharge, and they provide a complete, integrated turn-key solution for sewage treatment, sludge conditioning and dewatering. They include a customized telemetry control software program and PLC control panels to allow for complete automation, as well as remote monitoring. Outlook for the technology Continued expansion of the mining sector, both in North America and around the world, will mean a continued need for effective and workable wastewater treatment systems. Mobile MBR treatment plants are likely to play an ever-growing role in meeting the needs of this sector. Choo Sung Tai, P.Eng, is with Filter Innovations.

 Toronto fined for 2006 sewage discharge Recently, the City of Toronto pled guilty to one violation under the Ontario Water Resources Act for not operating its sewage works in accordance with its Certificate of Approval. The Court heard that, in December 2006, the City’s Ashbridges Bay treatment plant discharged partially treated sewage into Lake Ontario as a result of heavy rains and a bypass gate remaining open. There were no impacts to drinking water as a result of this incident. Since it was winter, there were no impacts to local beaches. Specifically, on December 1, 2006, the plant bypassed partially treated sewage, due to heavy rainfall. This bypass was permitted by its Certificate of Approval. Once the rainfall subsided, city staff instructed the plant’s computerized system to close the bypass gate and believed the bypass gate had been closed. But the gate remained open for another three and a half days before being discovered, allowing partially treated sewage to continue to be discharged into Lake Ontario. A ministry inspection after the incident found a required flow measuring device had failed to monitor and measure the bypass as expected. Since this incident, the City has made improvements to the plant, including upgrading the gate valve mechanisms and other enhanced hardware, and physical inspections to help prevent incidents like this from happening again.

Water Treatment

Faster multiple parameter water testing procedure saves time and money By Gil Dichter ll laboratories and bottlers are required to test for total coliforms and E. coli. They also may be required to test for heterotrophic plate counts (HPC) and for Pseudomonas aeruginosa, to be in compliance with government regulations and to ensure that the finished water is safe for consumption. An innovative enzymatic procedure based on Defined Substrate Technology® is a rapid, easy method for the simultaneous detection of total coliforms and E. coli. The method allows the test to be performed either as Presence/Absence (100 ml) or quantitatively as MPN/100 ml. It is based on colorimetric and fluorogenic enzyme substrates for total coliforms and E. coli. with time to results at either 18 hours using Colilert®-18, or 24 hours using Colilert®. It is specific, requiring no further confirmation. At the end of the 18 or 24 hours, the 100 ml Presence/Absence with no change in the sample is negative. With a yellow color, it is positive for total coliforms. If both yellow and fluorescent, it is positive for E. coli. Wells that have a yellow color are counted and a Most Probable Number (MPN) chart is used to convert the positive wells to an MPN/100 ml value for total coliforms. Wells that are both yellow and fluorescent are counted and the same MPN chart is used to convert positive ones to an MPN/100 ml value for E. coli. Confirmation is not required with

this test. Defined Substrate Technology, which was introduced in 1989-1990, is in Standard Methods for the Examination of Water and Wastewater under Section 9223. SimPlate® is used for the quantification of HPC in water. It is based on Multiple Enzyme Technology™, which detects viable bacteria in water by testing for the presence of key enzymes known to be present in these organisms. The sample and medium are added to the SimPlate and incubated for 48 hours at 35°C. A blue fluorescence is produced under a 365nm UV lamp when metabolized by waterborne bacteria. The number of fluorescing wells under a 365nm UV lamp corresponds to a MPN of the total bacteria in the sample. This method is in Standard Methods for the Examination of Water and Wastewater, Section 9215E. A newly released product called Pseudalert® is a 24 hour enzyme test for the detection of Pseudomonas aeruginosa for water, bottled water, pools and spas. This method was compared to both Standard Method 9213 E and ISO method 16266 and found to give equivalent results in 24 hours. No confirmation is required. The test is based on a bacterial detection technology that signals the growth of Pseudomonas aeruginosa through the hydrolysis of a substrate present in the reagent. Actively growing strains have an enzyme that cleaves the substrate to produce a blue fluorescence under a 365nm lamp. Samples are incubated at 38°C for 24 hours. At the end of the 24 hours, the 100 ml Presence/Absence with no change in the sample is negative; with fluorescence under a 365nm UV lamp, it is positive for Pseudomonas aeruginosa. For quantification, wells that have fluorescence under a 365nm UV lamp are counted and an MPN chart is used to convert to an MPN/100 ml value. Gil Dichter is with IDEXX Laboratories.

Water Treatment

Wireless communication allows water treatment systems to be controlled from anywhere By Sadiq Khan any water treatment processes are stand-alone assemblies which frequently use a PLC or a microprocessor based controller. Often, remote notification or diagnosis are not possible, but would be very useful for operations personnel. Being able to address a problem in its early stages can be advantageous in virtually any process. With this in mind, the Burkert Research & Development team has developed a multi-purpose process and water chemistry controller, called mxCONTROL. It has integrated an HMI, PLC, data logger, enclosure and power supply, and is designed to be connected live to the Web with an on board Ethernet port. This is all assembled in a NEMA 4X enclosure. Normally, to make a system accessible from a remote location, a modem with dial-up connection is required, or it would have to be connected to the facility’s network. Using a phone line can be an issue because one of the signal lines coming into the building would have to be used, before it can be put through the operator switchboard. This would reduce the number of simultaneous calls the building can handle. Connecting the system through Ethernet would require a specific port to

be opened on the network. This can create a security risk. However, the Burkert controller does not need to be connected through a phone line or a facility’s network. It is capable of just using a SIM card, or a 3G USB stick, when connected through a router. Any cell phone carrier that provides service in the area can be used with a simple data plan. The controller uses the 3G signal to send out E-mails when it

enters an alarm mode, or predetermined warnings. This makes the system a complete stand-alone assembly that does not use any of the end user’s resources. Since online communication security is becoming more of a concern, four levels have been incorporated within the type 8620 mxCONTROL: • The device does not echo when using the “Ping” function. This makes it almost impossible for hackers to locate.

Some of the pre-determined control functions make the controller very easy to set up, while allowing optimum process control. Some of these functions include: general PID control, conductivity control, on/off or PI control, oxygen scavenging, corrosion display, pH control, chlorine/Redox Control, batch dosing, biocide dosing (14 day program with 8 dosing events per channel), monitor module, totalizer function. The standard controller is designed for applications that require four analog inputs, two PT100 temperature inputs, four digital/frequency inputs for flow (up to 2kHz), four on/off binary inputs, four analog outputs, five SPDT relays (250V AC/DC, 10A), and two digital/frequency outputs potentially for dosing pumps. The maximum number of simultaneous control functions is eight but other input/output configurations are available upon request.

Pumps

Remote pump monitoring saves time and money on unique sewer replacement project n pump rental situations, both the vendor and the customer need the equipment to perform as expected. But even the most reliable equipment can experience issues during operation, especially in temporary setups. It isnâ&#x20AC;&#x2122;t practical or cost-effective to hire a team of people to stand guard 24/7 in case of equipment failure. RACOâ&#x20AC;&#x2122;s AlarmAgent.com continuously monitors applications and provides notification of any problems as they occur, allowing for immediate action. This can save significant time and money for the company and its customers, while providing reassurance for all involved. Most recently, one pump company rented out 14 temporary bypass pumps, each fitted with an AlarmAgent.com Remote Terminal Unit, for the Lake Oswego Interceptor Sewer (LOIS) project in Oregon. The project involved replacing a 50year-old, corroded and hazardous sewer line running through the 405-acre Oswego Lake. These pumps were used to handle effluent during construction of the new interceptor sewer. The existing sewer line consisted of 20,000 feet of sewer pipe ranging from 12 to 36-inches in diameter and was constructed in the early 1960s. Over 90% of this pipe lay within Oswego Lake, its bays and canals, with the remainder located onshore. Some in-water portions of the pipe were buried, but over half was supported above the bed of Oswego Lake on timber and steel piles. Replacement was necessary, as the existing system had become too small and the steel pile supports and hardware were corroding and were at risk of collapse. Many alternatives were evaluated to correct existing LOIS deficiencies in an economical and reliable fashion. In August 2007, after many public hearings and community briefings on the replacement alternatives, the Lake Oswego City Council recommended replacement of the LOIS system with a combination of pile supported pipe and a buoyant, gravity flow pipeline. During the project, the level of Os-

wego Lake had to be lowered to allow construction and pipe installation. The Lake Corporation begin lowering the lake level in September 2010. Elevation after drawdown was 16-20 feet below its normal level. Water was scheduled to remain at this level until April 2011, when refilling was to begin. The Oswego Lake area serves as home to 700 residents and is a focal point for the entire surrounding community. With an aggressive timeline and a price tag of about $95 million, everything had to go smoothly. Whenever water levels rose too high, fuel ran out, or a backup pump started up, the AlarmAgent.com system notified the company, which could then take prompt action. The project is scheduled for completion by the end of 2011. The ability to receive alarms and respond immediately helped LOIS stay on schedule and within budget. Workers were able to correct problems before they escalated. They avoided any potential

pipeline backups, which could have resulted in sewage spills, fines, angry residents and delays in project completion. Also, without it, the project managers would have had to pay people to monitor the pumps around the clock, in order to meet the contractâ&#x20AC;&#x2122;s mandate for 24/7 monitoring. AlarmAgent.com only required one person on site, instead of 14 for monitoring purposes. The pump company also benefits from the fleet management capabilities of AlarmAgent.com. It uses the system for centralized management of its entire rental fleet across multiple job sites and branches. Because the system is wireless, the company can manage equipment wherever wireless coverage is available, which is across 98 percent of North America. RACO is represented in Canada by SPD Sales.

Wastewater Treatment

Engineering treatment wetlands for various wastewater streams By Mark O. Liner

ringing a demonstration facility to the doorstep of a client is always an effective way to provide proof that a treatment system works. Some vendors offer the service by trucking a test unit to the site and running the treatment system on the actual wastewater needing treatment. Treatment wetlands are in a grey area between vendor technology and a consulting engineer’s “solution,” so no sales representative is going to show up with a wetland on a flatbed. However, there are facilities, such as the Centre for Alternative Wastewater Treatment (CAWT) at Fleming College in Lindsay, Ontario, that routinely test wetland systems. Another example is New Brunswick’s NATECH, which is currently testing the suitability of wetland treatment technology on byproducts of the local natural gas industry. Experience from these facilities has played an important role in taking the science of wetlands and using it for the engineering of projects.

Wetland systems are larger than mechanical systems. There is a trade-off between mechanical complexity and land. Wetland systems don’t need as much attention, or care, as their mechanical counterparts, are typically constructed on-site by civil contractors, and have few, if any, moving parts. Historically, the question of how to quantify performance has been left to statistics and heuristics. Recent improvements in the engineering of wetlands have helped increase predictability. Engineers have borrowed the biology, chemistry, and hydraulics of the wastewater industry and are employing them successfully to create treatment systems that perform like sewage plants but look more like … a field of plants. Inclusion of aeration in subsurface wetlands has greatly advanced the ability of the systems to degrade hydrocarbons and ammonia reliably. This is critical for the design of wetland systems used for spent de-icing fluids at airports, contaminated groundwater, or tailings water from gold mines. And, by using proven

hydraulic and thermodynamic principles, designers are creating wetland “reactors” that are stable and more reasonably sized. These reactors increase the reliability and performance over past systems by ensuring proper reactor kinetics and complete use of the wetland, with minimal shortcircuiting. Dr. Jim Higgins of Stantec, an early leader in treatment wetlands, piloted a number of systems at the University of Guelph’s Campus d’Alfred. The work was carried out to support development of kinetic variables that can be used to scale up systems from pilot to full scale. For example, Buffalo Niagara International Airport decided to pilot-test an aerated wetland to examine the rate at which de-icing fluid in cold stormwater could be degraded. The only way to go forward with confidence in this case was to build a model, put it in a walk-in freezer, and give it a test run. The results more than proved out the concept and were ultimately used to size the system now being operated at the airport.

Wastewater Treatment At Fleming College’s CAWT, Dr. Brent Wootton, director and senior scientist, leads a team of researchers who study innovative forms of wastewater treatment. The centre has carried out extensive research on constructed wetlands and alternative forms of wastewater treatment technology, such as anaerobic bioreactors for metal removal, and floating wetlands for use in stormwater ponds. The CAWT has state-of-the-art facilities, including six outdoor research rest cells for wetland studies, 20 ponds, an indoor greenhouse research facility, climate-controlled environmental chamber, and a fully equipped analytical laboratory. 1. Airport de-icing glycol. Buffalo Airport uses over 200,000 gallons of glycol-based product for aircraft and pavement deicing annually. Spent de-icing compounds are collected within the airport’s stormwater collection system and require treatment prior to discharge. To evaluate the ability of an aerated gravel bed to treat the stormwater on-site, a treatability study was conducted on a pilot-scale treatment system at Campus d’Alfred. Results from the testing demonstrated 95% treatment and were used as a basis for sizing the full-scale 10,000 poundsBOD5/d treatment system. Then Naturally Wallace Consulting (NWC) was selected to take the pilot results to full-scale design. 2. Gold-mine tailings. A remote gold mine in South America was in need of a low O&M system to treat ammonia from the cyanide-laden water in the tailings pond. Over 16,000 m3/day of water required treatment prior to discharge to the adjacent continued overleaf...

river. A treatability test was conducted to determine the rates of ammonia removal and to support the sizing of the wetland system. Testing was done in three phases. In the initial phase, artificial leachate was formulated and tested in a wetland reactor located at Campus dâ&#x20AC;&#x2122;Alfred. During the second phase of testing, actual water from the site was shipped to the laboratory for testing in the same reactor. During the final phase of testing, a reactor was constructed and tested on-site. Results from the testing demonstrated successful removal of ammonia, with no inhibition of nitrification. 3. Refinery wastes. A pilot scale subsurface vertical-flow wetland was constructed at the former BP refinery in Casper, Wyoming, to determine degradation rates for chlorinated organics. In particular, the water required treatment for benzene, toluene, ethylbenzene, and xylenes in cold weather. The four-cell pilot system, operated in 2002, provided insight into the value of utilizing aeration within the wetland system to expedite the rate of treatment. The


Wastewater Treatment value of a mulch cover for bed insulation was also investigated. Treatment rates from the pilot work were used to design a full-scale system capable of treating up to 11,400 m3/d of gasoline-contaminated groundwater. The full-scale system, which was designed by NWC, achieved compliance levels within one week of startup. 4. Aquaculture. Sedimentation and screening are primarily used for solids removal in flow-through aquaculture facilities. These physical treatment methods remove settleable solids and particulatebound nutrients from the wastewater. But they do not treat the dissolved fractions such as total ammonia nitrogen, phosphate and biochemical oxygen demand (BOD5), that can harm the receiving aquatic environment. A constructed wetland was installed after a septic tank at the Haliburton Highlands Outdoors Association in Haliburton, Ontario, which operates a 300m3/day flow-through salmonid hatchery. Intensive monitoring examined the ability of a subsurface flow constructed wetland to continued overleaf...

treat the concentrated wastewater flow that is produced during daily vacuuming of the hatcheryâ&#x20AC;&#x2122;s raceways. The wetland was operated for a year as a saturated horizontal flow system and has just been switched to a partially unsaturated vertical flow system for comparison purposes. The saturated horizontal flow configuration successfully treated concentrated wastewater even in extreme cold conditions. It is anticipated the unsaturated vertical flow configuration will increase

treatment performance. 5. College wastewater. An integrated treatment system, which combines an engineered wetland and PhosphexTM technologies (EW-Phosphex), was installed to study treatment efficacy of college wastewater. The system configuration consisted of a conventional septic system, followed by a horizontal wetland, then by a forced aeration engineered wetland cell, and ending in a Phosphex polishing unit. The Phosphex polishing unit contained

steel slag intended for removal of phosphorus and pathogens. The integrated system was monitored in the winter of 2010 to determine treatment efficiency, including removal of phosphorus, ammonia, nitrate, BOD5, total coliform, E. coli, metals, metalloids and pharmaceutical compounds. Most of the contaminants monitored were effectively removed by the treatment system. Ammonia removal was as high as 79%, while phosphate, BOD5, total coliform and E. coli were greater than 99%. Pharmaceutical removal ranged as high as 98%. Treatment wetlands are now being used over a wide spectrum of applications. Their success depends greatly on the front-end pilot work and the people and companies doing it. Pushing science to the limits, the pilots allow full-scale engineering of wetland projects. And, all this work can be done at a number of Canadian facilities, without having to put a wetland on the back of a truck. Mark O. Liner is with Naturally Wallace Consulting.

the discharge of sodium hypochlorite into an effluent channel that leads to the Don River, resulting in impairing its water quality. The company had a contract to complete upgrades at a sewage treatment plant in Toronto. The project required that the outdoor containment area surrounding the chemical storage tanks of sodium hypochlorite be expanded and a drain be installed to allow for easy removal of rainwater. The containment area was de-

signed to trap any sodium hypochlorite which might escape the tanks or piping. On September 11, 2009, during construction activities, a pipe was broken accidentally and approximately 3,446 litres of sodium hypochlorite discharged from the containment area and entered the Don River through the treatment plant’s effluent channel. No effort was made by the company to stop the chemical from leaving the containment area.

Biosolids Management

Designing a biosolids management plan involves many considerations By Tom Woodcock astewater treatment plant owners and operators have a significant decision to make when selecting a biosolids management plan. A thorough evaluation of treatment options should be made, taking into account local soil conditions, regulatory requirements, and capital and operational costs. The processes practised in Canada for over 60 years are land application, incineration, and land-filling. Each of these methods has known environmental concerns. In recent years, the Ontario government has passed and amended legislation that regulates biosolids management practices. These regulations include O.Reg. 267 of the Nutrient Management Act, and O.Reg. 347 of the Environmental Protection Act, which stipulate: • The locations and soil conditions necessary for land application; • How many months of the year land application is permitted due to weather constraints; • Maximum allowable pathogenic content in biosolids; • Maximum allowable metal concentrations in soils post-biosolids application; and • Treatment process and storage requirements at wastewater treatment

plants. O.Reg. 267 specifies that biosolids can only be applied to agricultural lands when there is less than 5 cm of snow on the ground. The result is that biosolids must be stored at wastewater treatment plants, or a centralized biosolids facility during the restricted application period. In Ontario, this is typically from October to March. Furthermore, this regulation defines permissible locations for biosolids appli-

cation sites, specifically the proximity of an application site to underground aquifers and bodies of water, whether streams, rivers or lakes. The maximum allowable pathogenic content in the biosolids is stipulated, requiring stabilization treatment to reduce colony-forming units (CFUs) present in the biosolids. CFUs are a measure of the viable bacterial cells in a sample. O.Reg. 419 of the Environmental Protection Act regulates the maximum allowable concentration of combustion

Environmental Science & Engineering Magazine


Biosolids Management gases and particulate matter generated by incineration of any material. The incineration of biosolids generated from treatment processes at wastewater facilities falls under O.Reg.419 as biosolids are considered a solid waste. Reductions in the maximum allowable concentrations are to be staged, and are currently regulated under Schedule II, which is set to expire on Jan. 31, 2020. After that date, Schedule III will take effect and multiple hearth incinerators may not be able to achieve the maximum allowable concentrations stipulated. In addition, there are Canada-Wide Standards developed by the Canadian Council of Ministers of the Environment for dioxins, furans and mercury air emissions. These regulations determine the treatment process required at wastewater treatment plants once a biosolids management plan has been finalized. Land application The requirement for treatment plants to store stabilized sludge during the nonapplication period increases a plantâ&#x20AC;&#x2122;s footprint due to the need for large storage

tanks and digesters. Stabilization of wastewater biosolids is required prior to land application to reduce pathogen levels. This can be achieved by conventional digestion, whether it be aerobic or anaerobic, or, alternatively, by chemical or biochemical reactions. There are several processes available on the market, such as Lystek, N-Viro and Bioset. Adding lime to biosolids creates a Class A product that is rich in nutrients and can correct the pH of acidic soils. This is especially beneficial to farmers in areas with acidic soils. Digestion can be divided into two subcategories of treatment, aerobic and anaerobic, and each have unique process requirements and characteristics. Aerobic treatment requires oxygen to be present in the process environment to promote the breakdown of biomass by micro-organisms. In anaerobic digestion, gaseous oxygen is detrimental to the process, and micro-organisms are able to digest biomass in the absence of oxygen. The end products of aerobic digestion are mainly carbon dioxide and water, whereas the end products of anaerobic di-

gestion are water, methane, carbon dioxide and trace amounts of hydrogen sulphide. Aerobic digestion is a delicately balanced process, that requires the control of dissolved oxygen levels, temperature, biosolids feed rate, and pH to create an environment that promotes the digestion of biomass by bacteria. Dissolved oxygen levels in the process environment can be monitored, and used to control the aeration of the aerobic digestion tank to achieve an efficient process. On the other hand, anaerobic digestion requires the control of temperature, pH, biosolids feed rate, and mixing. The pH of both digestion processes must be controlled to prevent the biomass from becoming acidic, which reduces the efficiency of digestion reactions. In an anaerobic digester, pH and alkalinity are monitored and the biosolids feed rate must be carefully controlled and regulated to achieve an efficient process. In an aerobic digester, pH, dissolved oxygen and alkalinity are monitored. pH can be controlled by either modulating the air continued overleaf...

supply to prevent nitrification or by adding an alkaline substance, such as sodium hydroxide, to compensate for the alkalinity consumed during nitrification.

28 | Summer 2011

Aerobic and anaerobic digestion also require the temperature to be controlled by modulating the heat supplied to the digester. If anaerobic digestion is used and

the digester is of a sufficient capacity, methane gas produced from the process can be used as supplemental fuel for the digester heating system. However, a major concern of anaerobic digestion is that, under NFPA code 820, anaerobic digesters are classified as Class 1, Division 1, due to the presence of methane and other combustible gases. This classification requires specialized electrical and mechanical equipment to be installed, in order to prevent an explosion. Once the sludge has been digested, the question of whether to dewater the biosolids prior to truck loading arises. Evaluating this process option is a function of the storage capacities of the digester(s) and the proximity of the land application sites to the wastewater treatment plant or biosolids facility. If a plant has large digester capacities and is relatively close to the land application sites, dewatering may not be practiced. Dewatering can be achieved via centrifugation, pressing, or vacuum filtration, each of which has operational benefits and concerns. If the dewatered, digested biosolids are stored for more

Biosolids Management than five days, significant odour issues will arise and high levels of pathogenic bacteria could return. When finalizing a biosolids management plan, plant owners and operators must take these factors into consideration. Incineration Incineration of biosolids, like digestion, is a complex process that requires close monitoring by personnel and automated controls. The â&#x20AC;&#x153;three Tsâ&#x20AC;? of combustion are the standard residence time (SRT) of the feed in the incineration zone, temperature of both the combustion reaction and the gases generated, and turbulence of the reaction mixture. The SRT is governed by the volume of the reaction vessel and the feed rate of biosolids, which is controlled by the sludge conveyance system upstream of the reactor, i.e., a screw conveyor or piston pump. Operational temperature of the incinerator depends on four variables: biosolids heating value, feed rate, supplemental fuel injection rate, and rate of aeration. Turbulence of the combustion reaction is created by the rate of aeration of the incinerator, and can be controlled

www.esemag.com

by trimming the air supply valves. Prior to incineration, biosolids must be dewatered to increase solids concentration. This allows combustion to occur at lower temperatures due to minimizing the amount of water present in the reaction. The main benefit of increasing the feed solids concentration is reducing the incineratorâ&#x20AC;&#x2122;s fuel consumption. Digestion is not required, and in fact is detrimental to the incineration process as it decreases the biosolids heating value. If the proper process conditions exist, dewatered biosolids cake can be autogenous. To achieve autogenous combustion, the incinerator must be a fluidized bed, combustion air must be preheated, and the biosolids must have a solids concentration greater than approximately 25%. Furthermore, air supplied to the incinerator must be controlled to create a feedto-air ratio that allows for complete combustion. The control of the combustion reaction determines concentrations of the gas products, which then have to be treated in a wet or dry scrubber before being emitted to the environment. Achieving com-

plete combustion reduces concentrations of carbon monoxide, particulate matter and other undesirable compounds, thus reducing the scrubber's chemical usage. A wet scrubber typically uses a sodium hypochlorite solution to remove pollutants. Prior to scrubbing exhaust gas, a heat exchanger can be utilized to preheat combustion air by recovering waste heat from the exhaust gas. This recovered heat can also be directed to other areas of the plant to reduce the plant's external energy consumption. Both land application and incineration of biosolids involve complex processes that require close monitoring and control to achieve an acceptable operational efficiency. However, biosolids generated from wastewater treatment can become a sustainable energy resource. Tom Woodcock is with R.V. Anderson Associates. E-mail: twoodcock@rvanderson.com.

Climate Change

Can insurance save us from climate change? By Brian Thomas

Shrimp boat washed up on dock during Hurricane Rita. Photo courtesy NOAA.

eople judge risk badly. We worry too much about minor hazards and are nonchalant about more serious ones. We’re especially inept at judging chronic long-term risks, like climate change. Insurance is a major part of how we deal with risk. Can it lead us to more viable ways to address climate issues? The picture is mixed. When we manage risk by buying insurance, we endure the slow, small pain of insurance premiums in exchange for a big compensation should something ugly happen. Insurers profit from our lack of knowledge about risk. Buying insurance goes against the grain, but paying our premiums gives us a little more security against fires, earthquakes, business interruption, and the numerous other events against which we can buy an insurance product.

P

Insurers review their policies annually and alter their terms if they see a change in the probabilities. When no major losses occur, the industry pats itself on the back for judging its risks correctly for that year. They’re happy and profitable. If the risk landscape changes, they absorb the payouts and adjust the terms accordingly. The optimistic point of view is that insurance can play a major role in guiding businesses and individuals toward more climate-friendly decisions. In theory, insurers study the real probabilities of known hazards, figure out a viable premium that gives them a profit and the policyholders the agreed-upon protection against the risk. When climate change raises the risks of flooding, business interruption, and other insurance hazards, the premiums go up, which can lead policyholders to change their behavior. Financing for a new factory can be

prohibitive or even impossible to get, if insurers won’t cover it. In practice, though, this theory is faulty for several reasons. Climate change poses special challenges to insurers. First, to single out one kind of insurance, many factors combine in extreme weather events. A hurricane has many causes, and global warming might only be two percent of the overall risk. If that part grows from two percent to five percent, it seems negligible, but in fact it’s quite significant. As one insurance executive said: “Even a minor increase in a risk like that can mean billions of dollars in additional losses to insurers.” If the winds are a few miles per hour stronger, and the storm takes a path through a heavily insured area, insurers can be overwhelmed. The same is true for other climate impacts. There have always been floods, ex-

But if climate change is turning up the dial, these familiar events may become more frequent, more intense, or changed in unexpected ways. Second, insurers are people too, and the cognitive blind spots that afflict individuals also affect the risk business. In practice, the insurance industry’s grip on certain probabilities often relies on seatof-the-pants methods that are subjective, and whose over-optimistic assumptions are sometimes rudely corrected by ugly surprises, especially when risks are constantly changing, as they are with climate change. Like all of us, insurers want certainty, even when they know that certainty cannot be attained. At a 2007 conference on hurricane science for an insurance audience, the world’s top climatologists discussed various topics in modeling and hurricanes. The head of underwriting at a major North American insurer complained about the hedged, qualified way the scientists state their conclusions. “Why don’t the scientists give us numbers we can use! These probabilities are too nebulous for us to write business with

them!” His impatience is widely shared, but the answer is no, scientists cannot. Third, insurance functions well when the risks of various hazards are truly independent of each other, and truly random. One trouble with climate change is that climate instability tends to make floods, windstorms, and other extreme weather more interrelated. One force binding all these factors together more tightly is land use, which is often part of a highly entrenched political juggernaut promoting the worst possible policies, such as building heavily in flood plains, or on beaches very prone to hurricane damage. Consider Florida, where the laws, business practices and general culture are geared to developing every square inch of land near water, not only oceans, but also lakes, streams, and wetlands. Even in the absence of climate change, this is an obviously dangerous policy. It’s also very popular. John Coomber, former CEO of Swiss Re, once grumbled that everyone wants to live on the most vulnerable beaches they can find in Florida. Governments occasionally try to buck the pro-development tide, but the politi-

cal pressure against anti-development forces is swift and merciless. Rather than resisting, many property and casualty insurers have pulled away from vulnerable coastal property in Florida. In response, Florida created its own public insurance pool. Result? Development continues, and the state fund is actuarially unsound; a major storm hitting a developed area would bankrupt the fund in short order. A few more storms would bankrupt the state of Florida, which would then call on the federal government, as the stand-in for taxpayers in all other states, to bail them out. These three factors mean that the insurance industry is weaker than it appears in matters of changing social and economic policies. The only way to change these entrenched policies would be for other social forces to align with the insurance point of view. That will require energetic political leadership and vigorous regulation. The market alone cannot save us. Brian Thomas is a sustainability consultant. For more information, please visit www.carbon-based-ghg.com.

 Abbotsford's new water source approved Hemmera has secured environmental approval for a groundwater extraction project in the City of Abbotsford. The Bevan Avenue Wells project will provide a clean, reliable source of water for Abbotsford and Mission over the next five years. The Bevan Avenue Wells Project is part of the Abbotsford Mission Water & Sewer System, which supplies water to over 200,000 residential, commercial and industrial customers in the Fraser Valley. The system includes a mix of surface water and groundwater sources. Faced with water shortages from recent dry summer months, an interim groundwater source was needed to meet demands for the City of Abbotsford and the District of Mission.

2,4-D is not an unacceptable risk The Quebec government's acknowledgement that "products containing 2,4-D do

not pose an unacceptable risk to human health or the environment" is an important admission that Canadians have been misled regarding the safety of this product. It also acknowledges the important role of Health Canada in pesticide regulation. "Our industry has long said that the decisions by Quebec and other governments to ban the herbicide 2,4-D and other common urban pesticides are not based on scientific evidence and do nothing to further protect human health or the environment. Now, Quebec has acknowledged that too," says Peter MacLeod, Vice President, Chemistry, for CropLife Canada. The agreement was reached as part of the settlement of a NAFTA dispute that challenged the Quebec government's ban on certain uses of 2,4-D as being without scientific basis. Health Canada concluded in a 2008 review that "risks to homeowners and their children from contact with treated lawns and turf are not of concern," and that "there is reasonable certainty that no harm to human health, future generations or the environment

"Hopefully, this agreement will help Canadians regain confidence in Health Canada's safety assessment and cause people to rethink whether or not they support the political decisions of governments to deprive them of access to these important tools with no good reason," says MacLeod.

The Ontario Environment Industry Association (ONEIA) has elected Derek Webb of Biorem Technologies, as its new Chair. Mr. Webb succeeded Robert Redhead, of Newalta, who had served as ONEIA chair for the previous two years. In that time, the Association’s membership continued to grow and it released two landmark public policy reports on the future of Ontario’s environment and cleantech sector – Ready to Grow (2009) and Still Ready to Grow (2011). www.oneia.ca

Disinfection

Managing contaminants in drinking water from the use of sodium hypochlorite By Gerald F. Connell rinking water system operators are always on the alert for contaminants in the chemicals used in water treatment, or that develop during the treatment process. Three significant contaminants are associated with the use of sodium hypochlorite as a disinfectant. They can all be traced to sodium hypochlorite, whether through the manufacturing process or decomposition of the hypochlorite: • Bromate, a potent human carcinogen, may be present in the bleach or produced as a result of the disinfection treatment process in the presence of bleach. • Perchlorate affects the ability of the thyroid gland to take up iodine. • Chlorate can affect the health of certain population groups such as senior citizens and children. Bromate Bromate comes from two separate

D

sources in drinking water. The first is in the hypochlorite manufacturing process itself. Sodium hypochlorite for bulk use is produced by reacting chlorine (liquid or gas) with sodium hydroxide. It can also be generated on-site with an electrolytic cell, using a brine feed. Sodium hydroxide solution contains bromine as sodium bromide, a salt of bromine, which is dissolved in the solution. Liquid chlorine can also contain elemental bromine. Almost all of the bromine in the two chemicals becomes bromate in the resultant hypochlorite solution. Bromine in the chlorine gas and bromide in sodium hydroxide are converted to bromate at the pH level of the sodium hypochlorite solution produced by the reaction. The addition of this hypochlorite in the disinfection process adds the bromate present in the hypochlorite solution to the finished water. Brine used

to feed on-site generation also produces hypochlorite with bromated levels. The second source of bromate is the raw water supply. Bromide ions can be present in the raw water supply, surface or groundwater. When water containing these bromide ions is exposed to disinfection using ozonation, the reaction of bromide with ozone will produce bromate ions. As a result, all water treatment plants in the US using the ozonation process are required to test for bromates in their finished water. However, treatment with hypochlorite does not require testing. The quantity of bromate present in finished water from the hypochlorite disinfection process can be controlled by limiting the bromide concentration in the hypochlorite source or the hypochlorite manufacturing process. Control of the bromated content added by hypochlorite will require the supplier of the sodium

Disinfection be included in the unregulated contaminant mandatory rule. Chlorate is formed when sodium hypochlorite decomposes in the bleach solution. Thermal decomposition of bleach is the primary source of chlorate. Quick turnover of sodium hypochlorite is the best method known to keep chlorate levels low. This could require frequent cleaning of the storage tanks so that a heel of â&#x20AC;&#x153;oldâ&#x20AC;? sodium hypochlorite is not kept in the tank. Temperature re-

duction and/or dilution on receipt from the supplier will also reduce the formation of chlorate. Once again, conversion of hypochlorite to chlorine gas would eliminate concern about chlorate. Gerald F. Connell is with Halogen Valve Systems. E-mail: tom@halogenvalve.com

hypochlorite to meet a more stringent guideline on its quality. One clear choice to avoid these issues is to use chlorine gas as the disinfectant, as there is no reaction with chlorine gas that will produce bromates. Perchlorate Perchlorate is a product of sodium hypochlorite decomposition, which happens over time and is caused by higher temperatures and concentrations. The longer hypochlorite is kept by the utility before use, the more likely there is to be a significant increase in perchlorate. Also, the development of perchlorateâ&#x20AC;&#x2122;s use in rocket propellants and the improper disposal of wastes from the manufacture of these propellants has been a reason for the appearance of perchlorate in raw water supplies. Rapid turnover of sodium hypochlorite and/or a reduction in hypochlorite inventory at the treatment plant will aid in the reduction of perchlorate development. Conversion to chlorine gas from hypochlorite can also be helpful, since perchlorate is not present in chlorine. Chlorate Chlorate is included in the USâ&#x20AC;&#x2122;s contaminant candidate list and will probably www.esemag.com

Site Remediation

Laser-based technology accurately detects subsurface contamination By Randy St. Germain hen fuel, coal tar or oil has leaked or spilled, site clean-up is not an exact science. In fact, designing a remediation program can be a guessing game when the contaminants disperse irregularly underground. However, some often-ignored technologies are available to screen sites much more accurately than traditional methods have allowed in the past. Traditional methods To locate and map out the subsurface contamination from coal tar, creosotes or other non-aqueous phase liquids (NAPLs), contractors have traditionally taken physical soil samples. Using drilling rigs or direct-push platforms, they bore multiple holes. While drilling down, they take samples at intervals, sometimes at a spacing of every five feet. After finishing one hole, they pick another location to do more sampling. When collecting samples from concentrated areas of contamination, contractors can often tell the presence of crude oil, fuel or other petroleum-based substances from the appearance and smell of the soil. However, to determine the magnitude of contamination or the type of substance, samples must be sent to a lab for analysis. It can take several days or weeks to provide results â&#x20AC;&#x201D; too late to act on the information in the field. Although this method has been accepted by regulators and used by contractors for decades, it often results in an incomplete picture of the subsurface. Or they may take samples at fewer intervals than they need to properly define the contamination. Furthermore, sampling is associated with other problems, such as poor recovery, compression of soils, hole slough, smearing and depth inaccuracies. After gathering data from soil samples, consultants then generate a plan for remediation, if needed. However, it is fairly common for remediation activities to discover uncharted areas of contamination. Then, a remobilization of sampling crews is necessary to create a more accurate depiction of contaminant distribution. Occasionally this must be re-

peated, increasing the time needed to complete the project and driving up costs. The reason that sampling does not usually detect all contamination during the first field effort is because oil, fuel and other NAPLs tend to disperse irregularly in the subsurface. This is contrary to the popular belief that these substances are typically contained in floating â&#x20AC;&#x153;pancake-shapedâ&#x20AC;? layers at the groundwater surface. In reality, contaminants are often distributed in many narrow seams and soil fractures, and sometimes end up trapped as far as 20 to 30 feet below the groundwater surface. Lighting the way To map out the distribution of NAPLs with better accuracy, some contractors have adopted direct push tools that use laser-induced fluorescence (LIF), a technology that was invented in the early 1990s. LIF allows contractors to take many more soil readings in much less time, because, rather than taking physical samples, LIF optical screening tools (OSTs) use light to gather information in real time as the probe is pushed into the ground.

In simple terms, LIF acts as a design tool that paints a detailed image of where coal tar, creosote or fuel has leaked and flowed since release. Results are presented in colorized logs that show the type and depth of contaminants throughout each hole that is logged. If site-wide context is desired, all the logs from a site can be combined with geographic coordinates to create three-dimensional conceptual site models (CSMs) using software available from a number of vendors. CSMs clearly illustrate the distribution of NAPLs in the subsurface, and show engineers exactly what they need to know to remediate the site correctly on the first attempt. LIF technology takes advantage of the inherent fluorescence of polycyclic aromatic hydrocarbons (PAHs) found in oils, fuels and other NAPLs. Bunker fuel, for instance, appears pale orange under visible-wavelength excitation, and coal tar emits red. On the other hand, light NAPLs, such as crude oil and diesel, do not fluoresce well under visible-wavelength light. They do react to ultraviolet (UV) excitation light and emit a bluegreen light.

Environmental Science & Engineering Magazine


Site Remediation Because of this phenomenon, different types of LIF instruments have been developed. These include the ultraviolet optical screening tool (UVOST) for detecting light NAPLs and the tar-specific green optical screening tool (TarGOST) for use with dense coal tars and creosotes. The particular tool used on a job depends on the type of NAPL expected to be found. Otherwise, representative NAPL samples can typically be sent to LIF vendors for free analysis. Generally, an LIF instrument consists of a steel probe with a sapphire window built into the side. Laser light is delivered to the window, as the probe is driven into the ground. Any PAHs from fuel or oil outside the window are excited by the laser light and fluoresce. A fiber-optic cable returns any fluorescence to the surface where it is recorded and displayed in real time. Above ground, the contractor and on-site consultants simply watch as the contaminant log develops, immediately reacting to the result and determining the next logging location, according to the results. Whereas the most liberal sampling plans only analyze the soil once every four feet or so, LIF instruments read and store measurements approximately once every inch for the entire time the OST is being pushed into the ground. This ability allows OSTs to discover small but important seams and fractures of contamination. Not only do LIF instruments produce more data per hole than sampling, but they also work more efficiently. Rather than stopping at various depths to collect soil, an OST probe continuously collects data while being pushed into the ground. Furthermore, LIF instruments can typically log between 300 and 500 feet per day, versus an average of 100 to 200 feet per day by sampling. The contractor does not need to wait for lab results, since LIF immediately identifies the type and relative concentration of fuel and oil in the subsurface. Since no contaminated soils are brought to the surface, LIF is considered a green technology. In addition, contractors no longer need to worry about exposure to contaminants brought up from the subsurface, and there is no investigationderived waste to manage.

Stormwater Management

Task order contracting streamlines procurement for Toronto stormwater project By Denise Costa, Rayna Volden and Tony Petrucci n August 2005, severe rainfall and an urban flooding event in the Greater Toronto Area caused extensive overland flooding and sewer backup. Over 4,200 basement flooding complaints were received. The Insurance Bureau of Canada estimated the damages to public and private property at $400$500 million, making it the largest natural disaster in southern Ontario and the second-largest in Canada. As a result, the City of Toronto embarked on a significant effort to define flood mitigation solutions. The Toronto Basement Flooding Protection Program (TBFPP) will provide a 100 year level of protection in the implementation areas. The City of Toronto used a Task Order Contracting approach for General Services Contract No. 1, which was the first portion of the overall program, involving sanitary sewer, storm sewer and watermain replacement works located within road right-of-ways. This was done to fast-

Stormwater Management track the program due to both political and public demands to get infrastructure improvement works completed as soon as possible, in order to mitigate future basement flooding. As Program Manager, CH2M HILL’s responsibilities included program management, pre-design, detailed design, services during construction, and postconstruction services. Task Order Contracting Task Order Contracting is a method of construction delivery, which allowed the City to complete watermain, storm and sanitary sewer reconstruction projects through a multi-year contract, in partnership with several contractors. Contractors were selected through a General Services Contract procurement process. In late 2009, once the designs were completed and all approvals in place, the City entered into negotiations with each of the selected contractors to award eight Task Orders for the initial General Services Contract ($30 million in construction value). These ranged from $2 million to nearly $10 million. General Services Contract No. 1 included all construction work substantially

performed within a 12 month period. The lessons learned from the use of the Task Order Contracting delivery method were then applied by the City in developing contract documents for General Services Contract No. 2. This will see four contractors complete $80 million worth of watermain, sanitary sewer and storm sewer replacement works by 2014. Streamlined procurement Task Order Contracting is a unit price type of contract, with estimated quantities for a group of construction projects that are similar in terms of their scope of work. This allows the selection of multiple contractors with an overall, single, competitively bid contract. It eliminates the time and expense of completing the traditional design-bid-build cycle for each project. Typically, a standard tendering period of eight to 10 weeks can be reduced to three to four weeks by utilizing Task Order Contracting. It also allows the Owner to decrease project duration and, as a minimum, maintain similar costs compared to a traditional designbid-build type contract, while increasing quality. Contractors competitively bid by pro-

viding unit prices for an estimated quantity of work associated with a group of construction projects. Each contractor will be asked to perform a series of projects one after the other. The price for each project will be based on the pre-set unit prices multiplied by the quantity determined for each specific project as part of the detailed design process. Prices for tendered items are never negotiated. However, prices for items not tendered must be negotiated and, once negotiated, the unit prices are applicable on other Task Order Contracts that are offered to the same contractor. The contractor’s performance is evaluated with every project and the prospect of additional work keeps the contractor motivated to provide timely, responsive, and high quality work. Task Order Contracting significantly accelerates project delivery without compromising quality. Figure 1 compares the tendering process for traditional procurement and Task Order Contracting. In order to ensure bidder commitment and secure competitive pricing for the General Services Contract, a decision continued overleaf...

was made that each contractor selected would be assigned Task Order Contracts with a cumulative minimum value of $500,000. This minimum value needed to be significant enough to convince bidders that they would secure enough work and to ensure that all pricing was competitive.

This also provided a means for the City to limit the assignment of Task Order Contracts to those contractors who did not perform well. During the pre-design phase, a decision was made to group 10 of the 72 assignments into eight Task Order Contracts,

with a total estimated construction value of $30 million. Up to five bidders would be selected, with the final number being based on the best value to the City. Once the bids had been received, three contractors were selected (all three bids were within the City's pre-tender estimate). This decision considered the pricing submissions, as well as the volume of work. It was essential to have the right number of contractors to complete the work within the term of the contract. Also, each contractor selected had to be awarded a significant portion of the work provided that they had available resources to perform high quality work, right from the very first Task Order Contract. Good contractor performance becomes a prerequisite of additional Task Order awards. The City can withhold the awarding of Task Orders to poor performing contractors. An active performance evaluation process is part of the Task Order approach which provides for flexibility in packaging and scheduling work to allow better management of traffic congestion and complaints from residents.

Stormwater Management Streamlined delivery The program has achieved fast, visible progress. All construction work, including 2,795 m of watermain, 1,560 m of sanitary sewer, and 6,346 m of storm sewer, was substantially completed within 12 months. Construction directly affected 871 homes. Based on actual schedules across eight Task Orders, the program had an average early completion of 41 days, and cumulative early completion of 332 days. Figure 2 shows the actual time for delivery of the eight Task Orders, compared to original estimates. Lessons learned 1. Pre-Qualification of Contractors: The City made a decision that the bid submission requirement to have all contractors submit information as to their ability and experience was not sufficient. More detailed information would be required from contractors to match their experience and resources to the complexity of future sewer reconstruction and watermain replacement projects. As a result, a pre-qualification document was prepared and contractors were selected to bid on future construction contracts, including the General Services Contract No. 2. There will likely be further refinement of the pre-qualification documents to screen contractors for specific categories of construction work associated with the TBFPP (i.e., deep sewer construction, large diameter sewers, difficult ground conditions, high traffic control areas). 2. Period of negotiation for Task Order Contracts: While most of the negotiations for the Task Orders as part of General Services Contract No. 1 were completed in a period of two to four weeks, there were some negotiations which required a considerable amount of time. In an effort to make the contractors more accountable in working with the City, the language in the tender call document for General Services Contract No. 2 was changed to clearly make the Task Order negotiation process part of the contractor’s performance assessment. Conclusion With General Services Contract No. 2 now in effect, the City will make further refinements to the tender call documents for future phases of the Basement Flooding Protection Program. The City has already used the Task Order Contracting method for their Watermain Replacement Program, and plans to explore future use of this method for road reconstruction and utility relocation programs. Anthony Pagnanelli, Director of Design and Construction for Major Works Facilities with the City of Toronto, endorses the Task Order Contracting approach, saying that “the success of this approach – and the entire program – makes it possible for the City of Toronto to meet its goals of protecting residents from future large-scale basement flooding. This approach was the first of its kind in the City and has created a model which other City programs have followed.” Denise Costa, Rayna Volden and Tony Petrucci are with CH2M HILL.

Ancient Romans set modern water and wastewater treatment standards By Michael Albanese hile on vacation, I wondered if I was the only one involved in our profession who asks questions about where the water comes from, and where the water is going? But, I think some of you, probably most of you, do exactly the same thing. During a recent visit to Italy, I toured the ancient city of Hercolaneum, near Naples. Aside from all the beautiful artifacts, buildings, mosaics, statues, frescoes, and other features of this place, I was amazed by the 2,000-year old water and sewer system! The Romans arrived in the Naples area in the 4th century B.C., populating the beautiful maritime coast with luxurious villas. In 89 B.C., it became an actual district of Rome. The territory was famous for specialized crops such as wheat, olives, figs, and vines that gave the best wines. Over 4,000 inhabitants lived in Hercolaneum. Incredibly, two thousand years ago the Romans already understood the significance of sewer systems and their direct relationship to public health. They engineered closed sewers, running under the streets, with access holes along the sewer lines, very much like what we have today in a modern city. Houses and buildings had drains that connected to the sewer system.

Street with underground sewer, in the ancient Roman city of Hercolaneum.

The city of Hercolaneum was near the sea, and the Romans also understood that collecting the sewage in a sewer system was not enough; you also had to treat it somehow. Public bathing, water recreation and, of course, fishing, were very important. Therefore, at the end of the sewers, they built large cisterns in series that provided solids settling, anaerobic digestion and decanting of the clarified

water before outfall to sea. That was enough to leave me speechless! The drinking water distribution system was also amazing. They had built plumbing (unfortunately made with lead piping) within the walls of the houses and buildings. We were shown an exposed pipe within a wall. Out of curiosity I measured it, and it was pretty close to the ½ inch standard size pipe we use today. This city also had fast food vendors at designated corners, men’s and women’s steam rooms with ornate mosaics, pools, fountains, shopping districts, schools, worship areas, art rooms, exercise areas and boat slips! Two thousand years ago it must have been a marvelous place, and it was all elegantly engineered and planned. Unfortunately, on the 25th of August 79 A.D. it was completely destroyed and buried by the eruption of Vesuvius, as was the more famous neighbouring city of Pompeii. On that horrible day, Hercolaneum was buried by a pyroclastic flow which originated from the volcano and reached an incredible speed, with temperatures high enough to liquefy rocks. This is why there are so many well-preserved artifacts. The high temperature of this burning mass carbonized clothes, sheets of papyrus and wood without destroying them, so you can still observe beams, staircases, furniture and trellises, and get

an idea of the customs of the time. Most of the four thousand inhabitants managed to escape, but at least three hundred people died due to the high temperatures, gases and ash. The city remained buried for over 1,600 years and was accidentally discovered by workers digging a water well in 1709. According to the World Health Or-

ganization, 14,000 people die every day due to waterborne diseases, more than for any other reason. Today, there are still many places in the world with no sewers, or open sewers, and no safe drinking water. What struck me the most is that, two thousand years ago, the knowledge to prevent much of this type of disease was clearly already available. If you can judge a civilization by its

sanitary engineering standards, the ancient Romans were ahead of their times. Hercolaneum is an amazing place to visit and, although smaller than Pompeii, it is well worth it.

Professional Development

The role of meteorology in the environmental sector By Jessica Reynen ccurate forecasts and assessments by meteorologists can save lives and money, making them a key element in the operation of several industries, including transportation, agriculture and energy. In the past decade, meteorology has become even more important due to the increased impact of severe-weather and natural disasters. Canadaâ&#x20AC;&#x2122;s meteorological activity spans both the private and public sectors to offer a wide variety of weather-related services to industries and individuals. It is estimated that over 100 private-sector organizations provide traditional meteorological services in Canada, and more than 1,000 other organizations employ meteorological practitioners in various positions, such as weather observers, airline pilots, weather broadcasters and utility planners. Recognizing the need for a mecha-

A

nism to provide professional credibility to meteorologists, Environment Canada and the Canadian Meteorological and Oceanographic Society Private Sector Committee recommended that Environmental Careers Organization (ECO) Canada develop a human resource strategy incorporating meteorological and weather occupations within its environmental employment certification programming. The labour market study, Changing Climate: Canadian Meteorological Employment, conducted by ECO Canada in 2005, found that the projected demand for trained practitioners in the private sector was high. But, with a large portion of these positions requiring a post-graduate degree or higher, coupled with low enrolments in related academic programs, there was a growing concern about shortages in the supply of trained meteorologists.

Demographic data from the survey also pointed towards increasing retirements in the public sector. Retirements from the Meteorological Service of Canada were estimated at about 8% annually, meaning that most job opportunities will arise from the need to replace veterans. Furthermore, most meteorological practitioners require job-related training, following the completion of a degree, before they can effectively begin work, and practitioners reported a wide range of continuing skill needs. Some 90% of employers reported that their practitioners needed upgrading and additional training in technical areas (e.g., meteorological science, 29%), and many areas of general ability (e.g., communications, 23%). In October 2009, Statistics Canada found that increased demand and heightened public awareness were having a positive impact on labour resources, resulting

Professional Development in what should become a re-stabilization of the industry. However 42% of the workforce is 45 to 64 years of age, and with most employers only rarely hiring graduates of bachelor programs, the focus will be on post-graduate training. Professional accreditation On June 5, 2011, after years of research and numerous conversations with key industry representatives, ECO Canada officially launched the Professional Meteorologist (P. Met) certification, which formally recognizes the unique skills and knowledge of meteorologists working in various fields such as forecasting, consulting and research. One of the original driving forces for Environment Canada’s partnership with ECO Canada on the Professional Meteorological certification project was David Grimes. His 35 years of scientific, research and management experience at Environment Canada and over 20 years’ experience working with the World Meteorological Organization (WMO) made his involvement in the development of the P. Met certification vital. He was recently elected president of the WMO by repre-

sentatives of its 189 member states and territories. The P. Met certification program is based on the development of national occupational standards for meteorology, which is a result of the collaborative efforts of the entire meteorological community, including the private sector, academia and government. “Ongoing professional development is crucial to success as a meteorologist. P. Met provides a framework for professional development and will ensure that Canadian meteorologists stay abreast of the latest forecasting techniques and advancements in the science,” says Christopher Scott, forecast operations manager at the Weather Network. “Encouraging meteorologists to be active educators in their community will serve to broaden the public’s knowledge of our profession and ultimately improve the understanding of weather forecasts.” “Like it or not,” says Claire Martin, on-air broadcaster at CBC, “your local TV weather presenter is often seen as continued overleaf...

sues of sustainability, climate and water. The new degree in meteorology will touch on our existing programs in forest growth, forest resources and environmental conservation, wildlife and fisheries conservation, and biomaterials.” A similar attitude also exists at the University of Worcester in the UK, where an Environmental Science BSc Hons course explores the theoretical and scientific explanations of many fields of environmental knowledge, including meteorology and

climatology. Another international example is the Saudi Presidency of Meteorology & Environment (PME), which received new environmental legislation and procedures in 2010. New environmental standards were written, and the PME is now strictly implementing them. Developments such as these, along with the leadership and free exchange of data and information provided through the WMO, are part of the continued development of the profession. The coming years will see the emergence of new technologies and opportunities related to issues such as climate change, and it is imperative that Canada is equipped with the highly trained and qualified meteorological workforce required to meet these challenges.

College professor. Arjen Y. Hoeckstra, a professor in water resources management at the University of Twente in The Netherlands, took virtual water a step further to create a “water footprint,” which considers both direct and indirect water. Together, direct and indirect water use is what determines the real dependency on water. Hoeckstra and other researchers working with virtual water and the water footprint concept see it as a tool to better manage freshwater resources on a global scale. www.amwater.com

Stronger requirements for natural gas development to better protect and inform New Brunswickers were announced recently by the provincial government's Natural Gas Steering Committee. Under these new requirements, oil and natural gas companies who want to engage in exploration, development and production will have to: • Conduct baseline testing on all potable water wells within a minimum distance of 200 metres of seismic testing and 500 metres of oil or gas drilling before operations can begin. These will be minimum requirements and may be increased. •  Provide full disclosure of all proposed, and actual, contents of all fluids and chemicals used in the hydraulic fracturing (fracing) process. • Establish a security bond to protect property owners from industrial accidents, including the loss of or contamination of drinking water. The provincial government has also committed to develop a formula so landowners and nearby communities can share in the financial benefits of the natural gas industry.

Alberta celebrates environmental excellence Twenty-nine industrial, manufacturing and municipal facilities demonstrating commitment to environmental leadership and stewardship have been recognized through EnviroVista, a voluntary program that acknowledges and promotes

facilities in Alberta that go above and beyond their environmental requirements. EPCOR Water Services Inc., Edmonton Waterworks System is the most recent company to reach Champion status. Three companies maintained Champion status this year, including Alberta Envirofuels Inc., an iso-octane plant in Edmonton; Alberta Newsprint Company, a newsprint mill in Whitecourt; and Umicore Canada Inc., a metal and chemical manufacturing plant located in Fort Saskatchewan. To become an EnviroVista Champion, a facility must meet the Leader criteria and commit to a stewardship agreement with Alberta Environment which demonstrates its continuous environmental improvement. Alberta also recognized 25 EnviroVista Leaders, including the addition of the City of Edmonton’s Waste Management Branch and Shell Chemicals Canada Ltd.’s Scotford Chemical Plant located in Fort Saskatchewan. To be an EnviroVista Leader, a facility must have a minimum of five years of exemplary emissions performance, a comprehensive, publicly-accessible, audited environmental management system, and five years without any enforcement activity under Alberta’s Environmental Protection and Enhancement Act.

BCʼs public sector is now carbon-neutral According to the BC government, the province’s public sector is officially carbon neutral, a first for any province or state in North America. To kick-start carbonneutral efforts, BC launched a $75-million public-sector energy conservation capital fund in 2008. It has funded 247 energy projects in schools, hospitals, colleges, universities and other government buildings across the province. Once complete, those projects are expected to reduce carbon output by 36,500 tonnes, create 500 jobs and save organizations about $12.6 million in annual energy costs. BC’s carbon-neutral regulation requires all public-sector organizations to measure, reduce and offset greenhouse gas (GHG) emissions from buildings, vehicle fleets and paper use. Provincial public-sector operations spent $18.2 million to offset 730,000 tonnes of GHGs in 2010, well

Westeel ...........................................43 XCG Consultants ...........................40

 within targets set when the carbon-neutral regulation was introduced in 2007. Operating a carbon-neutral public sector is a key part of BC's commitment to reduce GHG emissions by 33 per cent by 2020. The 730,000 tonnes offset by the public sector is equivalent to the annual energy use of 62,000 homes a year. It includes emissions from more than 7,000 buildings, paper use, and vehicle fleets with the exception of school and transit buses, which are exempt. Government ministries also offset emissions from business travel.

Energy-from-waste facility approved The Ontario Ministry of the Environment has issued a certificate of approval for the Durham/York Region’s energy-from-waste facility. The CofA, covering operational requirements related to air, noise, waste and stormwater, reflects the technical specifications of the Project Agreement, Environmental Assessment conditions of approval and the Region’s integrated waste management system, as well as complies with all relevant regulations. The facility will process waste to create energy in the form of steam, electricity and heat, with an approved capacity of 140,000 tonnes per year. It will only process municipally collected household waste (garbage) left over after the Region’s aggressive diversion efforts, such as recycling and composting. Also, the facility will be capable of recovering materials such as metal. Preliminary design and engineering of the facility is well underway. It is anticipated that construction will begin in the fall of 2011, with a target operation date of 2014.

 kets in Canada and the US. The new study will expand on the 1999 report by exploring water use over a more geographically diverse area, monitoring hot water use, examining outdoor water use (e.g., for landscaping) and assessing water conservation efforts in households. It also will integrate data from additional reports, in order to present a more comprehensive picture of residential water use. In each market, the utility participants will provide project researchers with historical water consumption data from a representative sample of 1,000 singlefamily customers. In nine of the 28 markets, researchers will select 100 homes for monitoring of indoor and outdoor water use and 10 homes for examining hot water use. The researchers also will send a water use survey to these customers. In the remaining 19 markets, researchers will survey 5,000 customers on indoor water use. The updated Residential End Uses of Water Study will be published in 2013-2014. www.waterrf.org

Oversight of Tar Ponds cleanup praised A recent report has found that the Nova Scotia Department of Environment continues to successfully regulate the Sydney Tar Ponds and Coke Ovens Cleanup Project. Findings show that it is effectively regulating the project and taking appropriate actions to protect the environment and address concerns about odour at the site. The Remediation Monitoring Oversight Board was created in January 2008 to monitor regulatory performance of the Department of Environment, including project permits and approvals issued, project regulatory issues, and public feedback. The board reports annually to the Minister of Environment. Cleanup is scheduled to be complete by March 2014. www.gov.ns.ca/nse

Groups appeal approval of fish farms Local community members from St. Mary’s Bay and the Atlantic Salmon Fed-

eration have filed an appeal to the Nova Scotia Supreme Court to oppose the creation of one of the province’s largest fish farms in the community’s traditional fishing grounds. According to Ecojustice, Fisheries and Aquaculture Minister Sterling Belliveau's approval in early June of two massive salmon feedlots received overwhelming opposition from local communities. The communities believe the feedlots, which will stock almost two million fish, will devastate their tourism and traditional fishing industries. The farms also threaten several endangered species, including the North Atlantic right whale, roseate tern, harlequin duck and wild Atlantic salmon. Ecojustice is representing the St. Mary’s Bay Coastal Alliance, the Atlantic Salmon Federation, Freeport Community Development Association and the Villages of Freeport, Tiverton and Westport. The groups are calling on the government to revoke the licenses and to put the interests of the local communities before the province’s aggressive aquaculture development plans. “Evidence from similar feedlots in New Brunswick shows that they will significantly deteriorate the habitat for key commercially harvested fish and significantly displace and diminish the quality of the existing lobster fishery in the area," said Karen Crocker of the St. Mary’s Bay Coastal Alliance.

AWWA releases drought preparedness manual The American Water Works Association (AWWA) has published a new Manual of Water Supply Practices, entitled Drought Preparedness and Response (M60). Providing a reliable supply of water requires planning for water shortages of varying degree and duration, and advance preparation for such shortages is the best defense. With that in mind, M60 provides tried-and-true strategies and tactics for municipal water providers, and introduces new tools and methods that will minimize the effects of short- to longterm drought. The manual provides a proven, sevenstep process to anticipate and respond to water shortages through a structured planning process. www.awwa.org/bookstore. 66 | Summer 2011
