Some systems are undersized to remove only large particles (3000-i-microns). The StormceptorÂŽ System can be designed to meet your project objective, whether it be large or small particle removal.When comparing systems, ensure that you are using the same particle-size criterion.

All manufacturers make performance claims.

How does the

Some systems cannot remove oil without the

addition of absorbents. The absorbents must

be removed immediately after a spill to pre vent the oil from leaking back into the water.

Most systems do not protect captured oil from high velocities - scouring will result.

A new take on the Flat Earth Society

Many examples of Roman engineering

yet remain impressive even to sophisticated contemporary engineers. Aqueducts carrying water from the mountains to the Eternal City can still arouse admiration for the way the Romans achieved their goals by surmounting grades and valleys with out the advantage of electric pumping systems. Admittedly they used slave labour, when such brutality was com monplace.

Roman engineers endowed their projects with artistry as well as engi neering ingenuity. The English city of Bath is a precise adjectival reminder that Roman engineering can still impress and indeed, endure for cen turies. The Roman baths in that city are still in use providing millions annually in tourist dollars, pounds and euros. A Scottish engineer once told me that some of the famous Roman fountains, still in use, were also pressure-relief devices as well as sculptural master pieces. Most ancient projects them selves are admired mainly for their artistry with little understanding of the benefits conferred by the engineering of roads, aqueducts, bridges, stadiums and water infrash-ucture.

It is a fool's game to predict the future but certain factors emerge when nations thrive; commerce, culture, education, literature and research, to name but five; but even these are not effective unless combined with a fair

judicial system where property rights, including intellectual properties, are protected.

It is ironic that at a time when the

global economy is mentioned virtually every day, a new controversial thesis has emerged in a book: The World is Flat: A Brief History of the TwentyFirst Century by Thomas Friedman.

The pace of progress has been stag gering. Who could have predicted tiny portable phones which can also act as cameras, play music and allow text messaging and be affordable by teenagers? Who could have predicted that Europe would design and fly a new Airbus which is vastly bigger than Boeing 747s? Technology is now impacting on virtually all industrial activities, lowering costs and vastly improving manufacturing processes, including the way this magazine is pro duced. Everything from research, writ ing, getting contributions by e-mail, copy editing and graphic designs are now produced in-house.

Now in its 18th year, Environmental Science & Engineering, began life with a small computer used for writing which was later composed in 'cold type' at the print er's shop. This 'cold type' was later pho tographed and tumed into film in a labori ous process which today's young joumalists have never even heard of.

Press day required two heavy boxes of film and pasted layouts being lugged to the printer where they then underwent yet other processes before the presses could roll.

Compare this to the May 2005 issue ofES&E which contained 88 pages and everything - including typesetting, pho tographs, and advertisements - was conveyed to the printer on two CDs weighing a mere few grams. This is a

quantum leap in printing which Gutenberg would not have recognized.

Conversely even as late as 30 years ago, typesetting was done in molten lead, the first of several laborious stages in the printing process of trans muting ideas from authors to readers, a process which Gutenberg certainly would have immediately recognized.

North America became a global leader in research and commerce with unmatched academic facilities and

engineering. Like the Romans, American engineers impressed the world with such epic projects as the Panama Canal and the Hoover Dam. The US also invented the world's first

skyscrapers which were a symbiotic structural breakthrough made feasible only by the invention of the elevator which in turn was the step child of electrical engineering, a discipline leading to French and Japanese high speed super trains.

Canada so far, is doing quite well, despite huge wastage through political blundering and corruption and patron age such as that emerging from the Gomery Enquiry. Canada prospered largely because of its abundant water and agricultural resources, plus its engineering expertise which is impres sive. Canadian engineers built the St. Lawrence Seaway; harnessed electrical power from Niagara Falls; built the CN Tower and other major projects. An

But those who ignore the mistakes of the past are doomed to repeat them - and there are warning signs emerg ing.

Today, warns Thomas Friedman,the percentage of US enrolments in sci ence and mathematics is declining, while demand for such expertise grows five percent annually. The proportion of US engineering graduates eurrently hovers around five percent compared to 25 percent in Russia and 46 percent in China. Economically, Russia is not doing well because of some turbulent legacies from political instability yet China is enjoying an unprecedented surge in its manufacturing sector, rang ing from shirts to high value technolo gy projects such as the Three Gorges Dam now reaching completion.

Feedback

Letters to the editor Dear Mr. Davey, I just received the ES&E magazine and I read your editorial page on the Kyoto accord.

I'm surprised and shocked by the lit tle science behind your editorial posi tion. The title of your article stands against the satire but the larger portion of your text is a cynical look at the fed eral government's actions. You can take a position against what the federal gov ernment, or the ruling Liberal party has done. However, if they did anything good recently, it would have to be the small steps forward that have been made toward implementation of the Kyoto protocol.

Do you realize that the worldwide emission reductions required under the Kyoto accord are just a tiny fraction of

your editorial, but feel the ranting about the ineptitude of the government is out of place with the title of your publication. I should have thought that "Environmental Science & Engineering" would provide the readership witl: facts about Kyoto.

We organized some workshops on air quality issues last year. In the prepa ration I was struck by the basic figures.

I too thought once that the I-ton chal lenge was silly, not any more. NASA puts the earth's atmosphere at 5.1kg x 10 to the 18th power, or 5.1 million bil lion tons.

of data would seem to indicate','mod els would seem to suggest', 'has the potential to be a reality...' etc., etc. No - we have moved to global warming somehow being an undeniable fact.

How did that happen? If we were to do

the reductions that are needed to "stabi

lize" the CO2 concentration at twice what it was only a few decades ago. I'm sure you know that even with "just"

doubling the CO2 concentration, we will still experience significant climate change that will have human, ecologi cal and financial impacts greater than any other foreseeable threat.

Since Kyoto itself is a small step in the right direction, you have the choice to help the leg move forward or you can decide to sulk, don't do anything and protest that the other leg (eg: the USA leg) is not moving fast enough.

The argument that Canada's emis sion reductions are too small to have a

significant effect on global warming is no argument. If every country with emissions below our own said that, 95% of the countries wouldn't do any thing and then in turn, the remaining 5% would refuse to do anything as well!

It's like an overloaded plane of 100 seats with 110 passengers booked. 1 can refuse to get off arguing that there will still be nine seats missing (my lit tle action won't have a significant impact)! But if everyone has 'this "great" way of thinking, nobody will give up their seat and nobody will get to fly (or worse, the plane will crash because it's too heavy!).

Jean-Philippe Monfet Environmental Director

Canam Group Inc. Dear Mr. Davey, I agree with some of the statements in

rational debate and divides viewpoints into 'good' and 'evil', (para. 1) 2. Global warming is undeniably a serious threat,(para. 4) The last few years certainly have been interesting to watch how that tran sition from 'well-meaning initiative' has been made and what the primary signs are of the uptake of the 'pseudo religion' aspect that you seem to be referring to. This assumes that 'wellmeaning' isn't just a euphemism for something that wasn't a tad secretly manipulative all along.

However, if acceptance of the notion that Kyoto had MY best interests at heart makes me queasy, the second ref erence makes me very uncomfortable especially that word 'undeniably'.

Really? No qualifiers such as 'some scientists believe', 'one interpretation

Vern Martin, Kitchener, ON

One of my several points was that Kyoto is a complex multi-disciplinary issue yet TV commercials featured a comedian to exhort Canadians to "take

the one tonne challenge."Istand by my point that it is Kyoto's 'Emissions Trading' which I think is "a witches

brew of economics, international poli tics, ecology, and oceanography, to name a few." And yes, I have heard at least one learned scientist seriously question the Global Warming concept, or, if you like, theory. In Arizona, I attended a seminar at Biosphere 2 where learned speakers discussed the issues, including the 'little Ice Age' to show how our climate has been volatile

in the past, eg. not all that long ago, in historical terms, when Londoners skat

None ofthe critical letters received so far has mentioned emissions trading which I believe will be unenforceable. — Tom Davey Dear Mr. Davey, In the September issue of ES&E, your magazine is writing about an health advisory issued by Health Canada. As a French Canadian mining engineer working in the chrysotile asbestos mining camp of Thetford Mines, I would have appreciated if the term tremolite asbestos contaminated vermiculite had been used instead of

plain asbestos. That difference is made in the official advisory by Health Canada.

I do make a living from chrysotile asbestos mining and I am not ashamed

of it because I strongly believe that it could be used in safe ways and help to improve the environment because it is a durable product (chryso-cement shin gles as example). 1 know a lot about risks and dangers and I realize that people don't know the truth about day to day risks. Asbestos is not a sub stance by itself, it is a family of miner als and it is divided into two groups.

Although chrysotile asbestos is a known carcinogenic substance, it is believed to be a lot less aggressive and biopersistent than tremolite and other amphiboles.

I would like to see an article about

the dangers associated with the 0.5 to 1.5% benzene content in gasoline. By the way, are you aware that benzene is classified by the lARC (International Agency for Research on Cancer) in the same group as chrysotile asbestos?

People are not afraid, except maybe by the price, when they fill up their cars but the risk is not zero. People are using cellular phones close to their brains and there is no proof that in the long run there will be no harm.

removed by tanker truck, whereas the MBR produces only about 15 per cent of that amount.

Tanker trucks are no longer required by the company since the fil ter press was installed. The press dewaters sludge from the DAF and the MBR to 35 per cent solids that are dis posed of in the landfill, which has reduced disposal costs by an addition al 15 per cent.

The efficiency of the system, com bined with the new equalization tank has also dramatically reduced odours from the plant. The new equalization tank is completely covered with only a small vent to release gases. Flowever, the membranes provide much faster treatment than the old batch reactor, so raw wastewater does not sit for long in the equalization tank. According to Ivan Facey the equalization tank is sel dom more than 50 percent full for any length of time.

"We have a subdivision right across the road from the plant, but since our new system went online we have not had a single complaint about odour," Ivan Facey says."With our old plant, it was almost a daily occurrence during the warm summer weather."

The operation ofthe system is high ly automated and fibers can be easily cleaned with a clean-in-place backpulsing process that forces permeate water back through the membranes.

Food and beverage producers throughout North America and the world are turning to advanced mem brane technology to achieve regulatory compliance with compact and costeffective on-site wastewater treatment

plants. The modular technology can easily accommodate much larger pro ducers with greater volumes of wastewater, such as a potato processing plant in Idaho that produces 5,000 mVday (1.3 MGD) of wastewater that is high in nitrogen. Constructed and commissioned in only seven months, ZeeWeed MBR reduced total nitrogen to only 6 mg/L, enabling the potato processor to safely discharge the efflu ent into the environment.

The membranes can also upgrade an existing conventional treatment plant to produce tertiary quality efflu ent. Such was the case for a large olive cannery in California that needed advanced treatment for wastewater that

is high in ferrous gluconate, acetic acid, salt, sodium benzoate, calcium chloride, soluble organics, and organic particulate. The membranes now filter up to 3,000 mVday (800,000 GPD) of effluent from the plant's bioreactors and produce high quality water that is discharged directly to a local river. The plant does not discharge any wastes to the municipal treatment plant and no longer pays municipal surcharges for wastewater treatment.

Membrane-based wastewater treat

ment options vary considerably for food and beverage producers—from retrofit applications for existing plants to compact new systems that will not only meet or exceed today's require ments but will position operators to comply with increasingly stringent regulations that are yet to come.

Instrumentation

On-line turbldlmeter helps Peel Region comply with new regulation

Ontario's Drinking Water Systems Regulation

By Wayne A.Harrison,C.E.T.

170/03 was introduced in June 2003, and replaced Ontario Regulation 459/00 (Drinking Water Protection Regulation for Larger Waterworks).

One new requirement involves continuously monitoring tur bidity in groundwater sources, following treatment.

The Region of Peel, in the heart of southern Ontario's major urban centres, operates water treatment systems serv

ing more than 1 million residents. This includes a dozen well sites that serve approximately 50,000 people in the Town of Caledon, where the region installed 22 TMS 561 turbidimeters from USFilter Wallace & Tiernan Products in May 2002.

The units provide continuous, on-line measurement of tur bidity, allowing the region to meet the new requirement and providing for efficient and safer operations.

Undissolved substances such as inorganic or organic par ticles, colloids or gas bubbles cause turbidity. As light strikes these suspended particles, a small amount of light scatters throughout the fluid. The amount and properties (size, shape and color) of these particles determine the light's intensity.

Turbidity measurement is based on the evaluation of the scattered light's intensity. The measurement value depends on the light's wavelength and either the measuring instru ments' geometry or the measurement angle. In order to

STORMWATER? NO PROBLEM

establish an internation

al turbidity standard, these parameters have been defined

by the USEPA(for U.S. applications) and ISO (for inter national applica tions).

The TMS 561 tur

bldlmeter is designed for continuous on-line measurement of tur

bidity. Its measuring chamber consists of a rotational flow assem

bly with a replaceable glass cuvette. A specially designed flow head eliminates the need for a bubble trap and ensures an immediate response time. Either a white light(USEPA)or infrared light(ISO)lamp generates a beam of light, which passes through the sample.

This light is measured by two sensors, arranged at a 90-degree angle. The resulting signal is conditioned by the integral elec tronics to provide a turbidity measurement reading in NTU. When calibrated against a known turbidity standard, the TMS 561 provides a continuous and accurate indication of turbidity.

The turbldlmeter can register turbidity as low as 0.10 NTU and as high as 1,000 NTU. With the optional data acquisition package, up to 255 turbidimeters can be networked simultaneously. The turbidimeter's one-piece design eliminates the need to mount compo nents for each turbidimeter.

The HycorÂŽ ROMAG Stormwater Screen is a fine bar screen designed specifically for combined sewer, sanitary sewer overflows and storm sewer outfalls. It is available in various

configurations, and can handle flows from 219 to 4381+ L/s (5 to 100+ MGD.) The solids and floatables retained by the ROMAG are diverted to the wastewater treatment plant to eliminate solids handling at the screen site.

The ROMAG is self-activating, self-cleaning, flexible, safe, automatic and energy efficient. It is an economical method of handling stormwater, and is ideal for remote locations.

are built into the measurement unit. Each turbidimeter sends

a 4-20 mA signal to the region's SCADA system, allowing operators to monitor turbidity levels remotely. Fast response time provides an early indication of process abnormality. To comply with the new regulation, the SCADA system can automatically shut off a well pump at any of the 12 sites if turbidity exceeds 1 NTU. As optics are not in contact with the sample, the chance of false low readings is reduced and the possibility of fouling the measurement detector is elimi nated, says the manufacturer.

at higher RPM to move debris by using a combination of vacuum and airflow.

Another plus for this vacuum unit or power pack is that it could be situat ed 200 ft from the receiving vessels while the receiving vessels are placed in close proximity to the work area.

This would mean that only 20 to 30 feet of working hose is required to move the debris and only 20 to 30 feet of hose would have to be broken down

if a blockage occurred. This feature keeps the potentially long (air) suction hose, that is connected from the receiv ing vessel to the power pack, from being plugged or frozen.

If, when vacuuming debris at -24 C, the hose carrying the debris to the receiving vessel forms a coating of ice and/or snow on the inside, the warm air that is generated on the 'vent-side' of the machine can be used to melt the ice and thus allows the use of the same

hose to complete the job.

When working with PCBs, the InViro-Drum can be used to segregate and collect contaminated water, oil or

solid waste into separate waste con tainers by changing the suction hose to the appropriate receiving vessel or container and by connecting the hose with the vacuuming-head/stinger to the

To protect the vacuum equipment from being contaminated, filters and polish ing systems can be added to filter out PCB contamination.

Because the power pack works as an independent piece of equipment within the system of moving debris, so the unit readily supports scrubbers, fil ters and remediation-filtration-systems such as a Mycelx-HRM Cartridge fil

Air Monitoring

Some vital do's and don'ts of

atmospheric testing

Every air monitoring program is

By David D.Wagner

filled with a number of choic

es that ultimately affect the safety of workers as they per form their daily duties. Typically the program is far from the core compe tency and productive focus of a com pany's workforce. Too often, the pro gram concentrates on doing only what is necessary to get by, rather than focus on what is involved with best practices in the industry. The following compris es some of the most common mistakes

encountered when the experts are called on to support their customer's atmospheric testing program: •Wrong sensors for the job.The most fundamental mistake in an air monitor

ing program is the lackof proper detec tion equipment. Somewhere along the way, a portable confined space gas monitor became defined as a four-gas instrument which detects oxygen, combustible gas, carbon monoxide and hydrogen sulphide. While two of those components, oxygen and combustible gas sensors, are a must in almost every

confined space application, the other two certainly are not. Confined spaces are different and the hazards found in

them will vary. Properly assessing the potential hazards up front, and ensur ing that the detection equipment is capable of effectively monitoring them is essential to the success of the pro gram.

• No remote sampling equipment.

Regulations governing work in con fined spaces require that the atmos phere is tested and cleared of hazards

prior to a worker entering the space.

This requirement would naturally lend itself to drawing a sample from within the space to the monitoring equipment.

Too often however, you will walk up on a confined space entry and find someone dangling the instrument into the hole on the end of a rope. Avoiding the cost of the proper sampling equip ment is impressive until the instrument is damaged in the depths of the space and the cost of the repairs exceeds the cost of the sampling equipment in the first place.

• Bad zero references. It's natural to

get to the job, take your monitor out of the truck, turn it on, look at the read-

ings and initiate a zeroing function.

This is done almost automatically without any knowledge as to whether or not the atmosphere you are standing in at the time is suitable for establish

ing a proper zero reference on the instrument. You must be certain that

the environment you are in is free of gas contaminants before zeroing your instrument and preparing to test the atmosphere. A clear indicator that you missed this step will be that the instru ment displays negative gas concentra tions in an absolutely clean atmos phere. If your instrument is not capable of displaying negative readings or automatically zeros during start-up, you likely will never know that this

22 Environmental Science & Engineering,July 2005

mistake has been made.

• Improper calibration. Any instru ment will only be as aceurate and reli able as its calibration. The key to a good calibration is usually as easy as verifying that the gas concentration listed on the cylinder label matches the concentration setting for calibration in the instrument. It sounds easy, but the

instances of instrument users picking up a cylinder of gas at one concentra tion and using it to calibrate an instru ment requiring a different calibration gas reference are too numerous to dis cuss further here.

• Failure to test tbe equipment before use. This is an old story. The only way to be certain that your instru-

Air Monitoring ment detects gas, is to check it with gas before you use it. Performing a func tional test on a gas monitor is a simple task which takes only a few seconds.

Why would you trust your life to a piece of equipment that you can only assume is functioning properly? Would you be comfortable stepping aboard an airplane if you knew that the pilot did not perform the required preflight inspection? Don't skip the preflight check on your gas monitor.

• No correlation between oxygen and combustible gas readings. Most portable gas monitoring instruments used in air monitoring programs rely on catalytic diffusion type combustible gas sensors to provide readings relative to the lower explosive limit (LEL) of the combustible gas. However, it is not usually understood that these sensors rely heavily on the presence of oxygen to provide an accurate reading. If the oxygen concentration in an environ ment is below 10% of volume, a poten tially dangerous situation may go undetected because the combustible

sensor will not function properly. The best practice is to always ensure a valid correlation between the oxygen and combustible gas readings on your instrument before assuming a non-haz ardous atmosphere.

• Test it then forget it. As discussed previously, regulations require testing the atmosphere prior to entering a con fined space. When the testing is com plete, the instrument goes back in the truck in too many cases. Why stop

there? Atmospheric conditions in many areas can change quickly and dramatically. Because all is clear and safe now is no indication that it will be

safe 15, 30 or 60 minutes from now.

Keep the instrument out and continue monitoring that atmosphere as long as the work continues. In this case, it is

clearly much better to be safe than

cases, none of these sensors will truly only respond to a single gas. Most sen sors are affected by cross interferences from vapors other than the target com pound. Generally there is very little understanding of the effects of cross interfering gases on sensors and, there fore, a great deal of misinterpretation of the data they provide.

• Weak internal standards. Don't

sorry.

• Lack of training. Frequently, a worker is handed an instrument,

assigned the task of performing the atmospheric testing, and sent on their way without any additional training or understanding of how to operate the instrument or interpret its readings.

Training tools are plentiful. Videos, computer-based training modules, online tutorials and personalized semi nars are all readily available to help convey the knowledge and competency necessary for using gas monitoring instruments. Don't go out without hav ing a clear understanding of the equip ment and how to use it properly.

• Misinterpretation of readings and data. Many people falsely believe that when they have identified that an atmospheric hazard exists but they do not know what the particular hazard is, they can take their portable gas moni tor into the area and it will specifically identify the problem. Nothing could be further from the truth. No portable gas monitor is capable of positively identi fying a particular unknown target.

While gas monitoring instruments use

rely on equipment manufacturers to set your policy standards. Equipment manufacturers are experts on their equipment. They are not, nor do they claim to be in most cases, experts in your field of operations. Make certain that your policies are driven by best safety practices and not by what is most convenient or economically fea sible. Simply relying on the "manufac turer's recommendation" is no way to ensure that your program is built on the foundation of observing best prac tices whenever possible.

These are only a few of the common mistakes made in air moni

toring programs throughout industry.

However, if you pay attention to these factors you will be well on the way to ensuring that your gas monitoring pro gram is following the best known prac tices in the field.

This meant it was being installed in very strong lime stone bedrock, with fractures to various depths at some loca tions. Open cut excavation using hoe-ram or blasting techniques was quickly ruled out due to the con straints posed by the site.

Critical requirements needed for accurate UV disinfection system sizing

Ultraviolet wastewater treat ment offers several advan

plant staff, the surrounding corrununity, and thus the liability exposure of municipalities and operators. Equally important, the treatment of effluent with ultraviolet light eliminates the creation and release of toxic disinfec

The advent of internal coatings has helped offset this decline in UV output. These coatings prevent the mercury from embedding into the quartz. As a result, such lamps provide about 80% of their maximum UV output at end-of-lamp-life (EOLL).

During the time that lamps are used for disinfection, the performance drop of current lamp technologies can be up to 20%. Given this significant decline in UV output, using the EOLL output as the basis for sizing is essential to ensure disinfection performance.

It is always preferable - and more

accurate - to base sizing on validated EOLL output data for the specified lamps. This is particularly true given the fact that NWRI and USEPA guide lines recommend that UV system designers factor in a decline in UV output of 40% to 60% - default values that are significantly lower than the UV output of many available lamps after one year of use.

Conclusions

The objective in designing wastewater systems using ultraviolet tech nology is to provide efficient, effective disinfection that meets permit require ments for the reduction of fecal col-

iforms during the entire operating life

What is UVDIS 3.1?

In 1986, the USEPA published the Design Manual for Municipal Wastewater Disinfection. In addition to detailing the procedural standards for field vali dation of UV dose delivered by a treatment system, it also included a math ematical protocol to estimate UV dose. At that time, only low-pressure, lowoutput (LPLO) UV lamps were commercially available. As a result, LPLO lamps and corresponding lamp spacing and reactor configurations typical of the time were used as the basis for this mathematical protocol. Such systems were also used to validate its accuracy.

regarding: • Actual disinfection performance of the UV system to be installed.

• Degradation of sleeve transmit tance by effluent.

• Efficacy and frequency of the cleaning system to be installed.

• Gradual decline of UV lamp out put over the life of the lamp.

Engineers, regulators, and deci sion-makers at the municipality should insist on third-party validation for the UV equipment they are consid ering - including the cleaning and lamp components.

Using the USEPA's mathematical formula as its basis, the UVDIS 3.1 sizing software was subsequently developed by an independent consultant. By automating the formula in the Design Manual, UVDIS 3.1 enabled engineers in Canada and the U.S. to quickly and easily estimate the theoretical UV dose, and dramatically reduce the time required to design and size UV sys tems. However, like the USEPA's original mathematical protocol, UVDIS 3.1 does not make allowances for new, high-output lamp technologies, and relat ed innovations in reactor design. In contrast to field validation, UVDIS 3.1 has some inherent drawbacks:

• Designed specifically for low-pressure/low-output(LPLO)systems only.

• Not applicable to LPHO or medium-pressure systems.

• Model results must be adjusted using arbitrary safety factors in an attempt to ensure system performance will exceed permit requirements.

• Dispersion coefficient and other variables are assumed values.

• Program is not endorsed by the USEPA, nor has it stayed current with advances in UV technology.

• A critical input to the calculation is lamp output (watts), however no stan dard method for absolute lamp output measure exists.

Biosolids Gaps in knowledge While scientific research has been

carried out, there are still gaps in knowledge. For instance, the Scientific and Technical report of the European Commission on Environment states;

"Today, many uncertainties remain concerning the transfer of pollutants (especially organic pollutants) to the environmental media and the food chain. Several issues would need to be

more accurately documented.

Amongst these issues, the following may be mentioned: • The importance of the runoff process in the pollutants' transfer should be assessed. Mechanisms need

to be understood, as well as quantities of pollutants concerned, and their fate.

• An issue of concern is the degra dation pathway of the organic com pounds in soil.

Compounds may be degraded into intermediary chemicals before total mineralization. The toxicity and leach ing potential ofthese metabolites is not well known. Lysimeter and field stud ies should be carried out.

• Long-term impacts of heavy met als and organic pollutants, in particular on soil micro-organisms and fertility, are not well documented.

• More data is needed concerning

the ingestion and absorption levels of organic compounds and, to some extent, heavy metals, by animals.

• There is also a lack of knowledge concerning the specific contribution of sewage sludge to pollutants' transfers.

• A survey ofthe organic pollutants' levels in sewage sludge should be per formed in the member states, in order

to gain an accurate appreciation of their occurrence. This may only be possible if standard analytical methods are set and broadly accepted.

• Available literature

Stormwater safety barrier for workers and any visitors to site. At one point in the dig, small amounts of explosives were required to loosen the soil. A Bobcat was lowered into the shaft and

used for excavating the earth. Once the invert elevation of the shaft was reached, the Bobcat was removed and replaced with tunnel jacking equipment.

Throughout the dig, all safety precautions were taken including the use offans for ventilation, ladders, safety plat forms, and lighting.

The shaft was required so that 95.5 metres of 1200 mm diameter jacking pipe could be jacked from the 3000 mm diameter maintenance hole riser at the base of the drop structure. The jacked pipe connects to the maintenance hole by means of a "doghoused" opening in the first 3000 mm riser at the base ofthe shaft to provide an outlet to the creek.

An internal granite box was specially designed by Niran to accommodate the velocity and weight of freefalling stormwater and dissipate its energy. Once the outfall pipe had been jacked into position and the 3000 mm diameter riser installed, the base of the drop structure was ready for construction of the 2400 mm x 1200 mm maintenance shaft

that contained the 900 mm diameter concrete drop structure.

The idea for the internal drop structure came from Hanson's engineers. There was some concern that an exter

nal concrete drop structure might shift and crack. In addi tion, an external drop structure (concrete or PVC) would have required a steel lined working shaft to accommodate pipe and equipment. The construction cost could have been much higher. With an internal drop, the concern about cracks in the concrete drop structure was alleviated and the

Jacking the outfall pipe from the structure at the bottom of the shaft, and construction of the headwall took 50 work

ing days. The process was described by the contractor as a traditional jacking job through silty clay till. Since the cylin ders of the jacking machine required more space than was available in the working shaft, the contractor built a 3-metre "tail tunnel" that extended beyond the circumference of the working shaft. The tail tunnel accommodated the cylinders of the jacking equipment. Once the pipe jacking was com pleted, the metal lined tunnel was completely filled and cov ered by steel wall plates. The jacking pipe was 1200 mm diameter pipe supplied by Hanson.

Niran Construetion Limited of Toronto, under the super vision of David Schaeffer Engineering Limited (consulting

engineer for Mattamy Development Corporation), construct ed the drop structure, inlet, and outfall to the Rouge River in approximately four months.

The precast concrete drop structure is believed to be the deepest in Canada for completing a stormwater management system for a residential development. Precast concrete man hole components and standard concrete drainage and jack ing pipe proved to be an easily installed, economical, longterm solution.

cost of construction reduced dramatically.

Construction of the maintenance shaft and drop structure took two weeks as all components were precast concrete maintenance hole components. Only two pieces per day were permitted to be installed since the space between the

precast concrete structure and the metal-lined wall of the shaft was filled with non-shrink fill, as work progressed.

Engineers required proper time for the fill to set.

The entire shaft is made accessible by a combination of aluminum safety platforms and steps built into the risers at the Hanson plant. Design engineer for this structure was Dave Grahlman of Gamsby and Mannerow Limited.

When work reached the elevation where the inlet pipe from the pond entered the vertical drop shaft, a special tran sition structure comprised of a weir and benching was spe

cially designed by the Hanson engineering team. The chal lenge was to provide benching that did not cause turbulence of the stormwater as it entered the structure, and reduced the

entrant coefficient for the flow transitioning from the 975 mm horizontal pipe to the 900 mm vertical pipe. Hanson

• The struts in the pipe had reduced the hydraulic capacity of the outfall so that it was not able to convey the full development design flow;

38 Environmental Science & Engineering,July 2005

• The City was incurring costs due to the regular maintenance of struts in the pipe; and, • An asphalt overlay on St Joseph Boulevard was scheduled for 2005.

This dictated that restoration of the out

Rehabilitation options It was realized that due to the prox imity of extensive street utilities and the potential traffic impacts, an open-cut sewer replacement might not be the most effective rehabilitation method.

Therefore, 11 alternative rehabilitation methods were considered, including shotcrete lining, tunnelling, slip lining (with rigid and flexible pipe), liner plate lining, cured-in-place lining, high-level overflow sewer and full sewer reloca

tion, and combinations thereof.

A two-staged evaluation process

was used involving an initial screening stage, in which the advantages and dis advantages of each option were inves tigated, followed by a detailed assess ment of the four best options. The short-listed options were: shotcrete lin ing, liner plate lining and open-cut sewer replacement (along the existing and new alignments). The detailed evaluation criteria that were applied included:

Based on RVA's findings, the following items were identified as being key to the suc cess of the current project: • Provision of a suitable mix design and optimum conditions for installa tion and curing; • All groundwater ingress through the CSP wall must be stopped prior to shotcreting; • Applying the shotcrete in a greater number of layers to improve durability; • Use of shrinkage compensator

a) Organic matter removal. Aquacan 6000 can remove an average of96% BOD5 at an organic loading of less than 630 g/m^day. As the loading increases, the BOD5 and CBOD removal decrease. With an organic loading of more than 11,500 g/m^day, the BOD5 and CBOD removal was approx imately 70%. This percentage can be substantially improved by installing a second unit in series.

An inadvertent bleach discharge from the cleaning oper ations in the winery produced a toxic shock in the treatment system. The recovery period from the toxic shock was remarkably short. In just 10 days, the unit recovered its steady performance, removing an average of 93% of BOD5 and CBOD.

The food industry is one of the largest consumers of water from the industrial sector.The cost of the treatment of food

processing wastewater is very high because of the high BOD levels. b) Total suspended solids removal. It was observed that 80% of the total suspended solids were removed at loadings between 250 to 3,250 g/m^day. c) Sludge removal. During the testing period of four months, the unit treated 217 m^ of high-strength winery wastewater. An average BOD loading of 2,500 mg/L pro duced 420 L of sludge with 5% solids. d) Mechanical performance of the unit. The Active Biological Contactor includes a proprietary RBC unit. This unit has been designed with Hexacell™ technology, which reduces the torque effects on the shaft. In that regard, and after 1,000,000 rotations with a load of biomass of 250 lbs the performance of the shaft met the most severe expecta tions.

Remediation

Reducing petroleum hydrocarbon contaminants in groundwater

Petroleum hydrocarbons have

By Phillip Lowery

become a nuisance at many sites across Canada. Leaking underground storage tanks (USTs) have caused multiple releases of volatile petroleum hydrocarbons (VPHs) and light extractable petrole um hydrocarbons (LEPHs) to the soil and water table. Many in situ remedial options, such as Air Sparging/Soil Vapour Extraction and Pump and Treat, have attempted to reduce high levels of these contaminants at the cost

of millions of dollars over many years.

Oxygen Release Compound (ORCÂŽ), an in situ technology, has been successfully applied at a former service station/car dealership in the greater Vancouver area. The applica tion of this safe and easy to handle powder has reduced high concentra tions of VPH, LEPH, and naphthalene since its injection in October 2003.

A preliminary site investigation was conducted to assess possible groundwater and soil contamination originat ing from eight former underground storage tanks historically used by both the service station and dealership. The USTs included four gasoline USTs, two bulk oil USTs, one diesel UST, and one waste oil UST. Possible soil

and groundwater contamination was expected, especially high levels of VPH and LEPH. Currently there is no UST or pump island.

Following the completion of a detailed site investigation, soil contam-

ination was found within and adjacent to the former gasoline UST basin.

Based on the results of multiple bore hole samples, the area of concern was delineated to include the former gaso line USTs as well as the pump island.

A total of 1,300 m^ was identified as contaminated soil while 1,350 m^ was estimated as contaminated groundwa ter. As expected, soil and groundwater contamination included VPHs (13,000 ug/L), LEPHs (2,600 ug/L) and, to a lesser extent, naphthalene (240 ug/L).

Remediation goals were established based on the standards set through the Contaminated Sites Regulation of British Columbia, specifically Com mercial Land use for soil and Aquatic Life standards for groundwater.

In October 2003, a total of 1,350

downgradient wells and a reduction to below 100 ug/L in all wells. Currently, five wells have sampled below naph thalene standards(10 ug/L).

ORC typically delivers oxygen to the subsurface for periods of up to 12 months. In order to continue the reduc

ing trends seen in VPH, LEPH, and naphthalene, a second injection using ORC Advancedâ&#x201E;˘ was completed in December 2004. This new formulation

of ORC is a calcium oxyhydroxide based material that offers more oxygen per pound than regular ORC.A total of 500 pounds was used to target the source area and continue reductions

over the following year. Based on the current contaminant reduction trends,

ORC Advanced is expected to meet the cleanup goals and expedite site clo sure.

The increased rate of enhanced

bioremediation allowed significant reductions throughout the plume with in one year of injection. The total cost for ORC and ORC Advanced product was $23,955. To date, a grand total of approximately $200,000 has been spent for excavation, ORC and ORC Advanced application, and associated remediation activities.

Pulp and Paper

It's not pulp fiction at a Weyerhaeuser P&P mill

Weyerhaeuser's Longview, Washington plant pro

duces more than 1,350

tons of paper a day. The plant processes 1.5 million bone-dry tons ofchips into pulp fiber production per year. Chips enter the facility by rail, truck or barge from five Northwest states. The chips are then stored by species, screened to remove contaminants, and transferred by con veyor for processing.

Nearly 200 employees produce rolls of liquid packaging board that will eventually be printed, scored, cut and formed into gable-top containers or cups by Weyerhaeuser's customers.

The liquid packaging board comes in many different grades, suitable for most common liquid container sizes.

During the packaging board manufac turing process, fibers are mixed and processed in a variety of ways to create the exact properties customers want in a finished product.

The Kraft Process

Like most paper mills, Weyer haeuser's kraft process is dependent on two primary liquors. White liquor, which is primarily sodium hydroxide (NaOH) and sodium sulfide (NajS), is used in delignification during the chip cooking cycle. Green liquor, which is primarily sodium carbonate (NazCOj) and sodium sulfide, is generated dur-

ing the liquor recovery cycle. Green liquor is then passed through the causticizing process where it is regenerated back to white liquor. The dregs are the remnants from the recausticizing process.

White liquor composition is very important in the control of pulp quali ty and uniformity. Green liquor com position has a direct effect on the effi-

ciency of the liquor regeneration process and determines the amount of makeup chemicals needed to guarantee

the desired white liquor composition.

Therefore, in order to achieve an ener

gy-efficient process and guarantee quality control of the pulp, accurate control of the key components ofthese liquors is vital.

In the summer of 2003, Weyer haeuser's Longview plant faced a rather "sticky" situation: a build-up of dregs in the green liquor clarifier over loaded a filter and required immediate attention.

An unplanned shutdown would have a significant impact on the Longview mill and its employees, to the tune of tens of thousands of dollars

per hour in lost revenues.

The typical way to solve the prob

lem - shutting down the pulping process, slowly removing the excess dregs from the system, and restarting production - simply was not an option for Weyerhaeuser. Adding to the chal lenge, the Longview mill is located on the scenic shores of the Columbia

River, so it was vital that all of the

mill's wastewater be properly moni tored and treated.

Baker Tanks delivered eight 21,000-gallon carbon steel Safety Vapor Tanks.

48 Environmental Science & Engineering,July 2005

Early identification saved the day "Weyerhauser's success and envirorunental safety is a direct result of our emergency business continuity

Pulp and Paper planning," said Jim Yount,former team development manager.

"Without immediate attention, we were in serious risk of potentially impacting production for both our cus tomers and our other plants," added Mr.Yount. The dregs slowly built up in the one-million-gallon green liquor clarifier. The bottom of the green liquor tank has sloping sides which allows the particulates to settle at the base of the tank. If the dregs mix with the green liquor, the filtering process from green liquor to white liquor is nearly impossible.

Within 48 hours, Baker Tanks had provided the plant with additional capacity. Eight, 21,000-gallon carbon steel Safety Vapor Tanks were mani

folded together to store 160,000 gal lons of dregs. The tanks were more than adequate to handle the liquid's high temperature of up to 190 degrees Fahrenheit and high alkaline content and allowed the dregs to settle until they could be sewered to the treatment system in a controlled fashion.

catch up naturally," Mr. Yount said.

He estimated that the plant general ly processes 25 to 30 gallons of dregs a minute or 35,000 to 40,000 gallons per day. In a quick timeframe, they were able to remove the equivalent of four days' worth of dregs and put process ing back online. Mr. Yount's team then focused on the settling of the dregs and the continued operation of the filter.

While Weyerhaeuser was able to avoid a major, unplarmed plant shut down thanks to quick thinking, they knew that given the nature of the plant's operations, the green liquor dregs would soon build up to emer gency levels again.

Eighteen months after the incident occurred, planned maintenance was done on the one-million-gallon green liquor tank in order to remove the dregs build up. Baker Tanks provided 20 Safety Vapor Tanks to remove the liquor and the dregs for cleaning.

The Sick of Dust report found six main types of chemicals in people's homes. All composite samples were contaminated by all six of the follow ing chemical classes: • Alkylphenols — Found in laundry detergents, textiles, hair-coloring, paints and all-purpose cleaners. These chemicals are widely recognized to mimic natural estrogen hormones leading to altered sexual development in some organisms.

In Arkansas, California, Colorado, Hawaii, Illinois, Maine, Massachusetts, Michigan, Minnesota, New York, Oregon and Washington, legislation is underway to phase out some of the most dangerous chemi cals. Europe can serve as an example.

Home to the largest chemical industry in the world, Europe is currently over hauling its chemicals policy so that highly hazardous chemicals will require special authorization to be pro duced and used. Regulators believe this will lead to many highly toxic chemicals being dropped from com merce and hasten the adoption of safe chemicals use in products and manu facturing processes.

HOBO Water Level Data Logger The HOBO Water Level Logger is a high-accuracy, pressure-based water level recording device that combines research-grade accuracy and durability with a price tag that is roughly half the cost of most comparable solutions. It provides 0.1 % of full-scale accuracy with a 9m measurement range and better than 3mm resolution. Unlike traditional water level loggers, which rely on cumbersome vent tubes and desiccant packs for operation, the HOBO Water Level Logger operates as a standalone unit. This simplifies deployment and eliminates many of the maintenance issues associated with vent tube-based loggers. A second HOBO Water Level Logger can be used for barometric compensation when required.

Report says pollution decreasing in Canada The Commission for Environmental

Cooperation (CEC) annual Taking Stock report shows pollutant releases going down between 1998 and 2002.

In its latest report, the CEC looked at the pollutant trends between 1998 and 2002 across Canada and the United

States. In the case of Canada, govern ment efforts together with those of industry for reduction, recycling and prevention of pollution led to a 13% reduction in pollutant releases that

Environmental NEWS pose risks to the environment and human health.

Lead emissions to air are highlight ed in the report. Overall since 1982, lead emissions to air have decreased by 95%, brought about by eliminating lead in gasoline and measures by industry to reduce lead releases over all. However, releases from metal min ing smelters still are a concern. The Goverrunent of Canada recognizes the need for further action and last year proposed pollution prevention plan ning considerations that would lead to reductions of lead emissions from

smelters by approximately 30 percent

by 2008 and 60 percent by 2015 from the 1998 levels while targeting particulate matter and sulphur dioxide.

Pollutant releases from Canada's

industrial heartland, Ontario, fell 24% between 1998 and 2002. As well, the

province ranks first in North America in recycling efforts which provides an economic and environmental benefit

to its industry and its citizens.

Rigorous inspections mean better drinking water protection The first progress report from Ontario's Chief Drinking Water Inspector confirms that overall the province has very good quality water and shows that the number of orders

issued to systems has decreased in the past two years.

The report shows that 99.7 per cent of almost 1.5 million water quality tests conducted in the last two years met Ontario's drinking water stan

wastewater treatment plant. Between August 14 and 17, 2003, approximate ly 293 kilograms of vinyl chloride monomer (VCM) leaked into the plant's cooling water system.

Under

normal

conditions, the

plant's cooling water would not be in contact with VCM, but on Thursday August 14, 2003, there was a power black-out which not only affected the operations of the company, but many other areas of Canada and the United

States. Contrary to its Certificate of Approval, the company's personnel failed to restart the cooling water sys tem after the power outage and as a result, unmonitored cooling water was discharged to the cut-off drain. It was not until August 19, 2003, that Royal Polymers notified the Ministry of the Environment's (MOB) Spills Action Centre of the discharge.

help in development of community and regional airshed plans. Nine such airshed plans have been developed in the last four years - more than were completed in the previous 10 years.

Among this year's projects are: • Up to $45,000.00 to replace air mon itoring equipment in Prince George.

• Up to $38,000.00 to replace air mon itoring equipment in Golden.

• Up to $28,000.00 to add additional air monitoring equipment in Cranbrook.

• Up to $12,000.00 to add additional water monitoring equipment in Kitchener.

Ontario to make polluters pay more for spills If passed Bill 133 would impose envi ronmental penalties of up to $20,000 a day for individuals and $ 100,000 a day for corporations. Unlike fines, which are handed down by the courts, Ministry of the Environment officials would assess these penalties within a few days of an unlawful spill. The new system encourages companies to make greater efforts to prevent spills and provides additional incentives to clean them up quickly.

When a penalty has been imposed, polluters could still face prosecution.

The proposed legislation would also hold corporate officers and directors more accountable. A conviction could

result in sentences ranging from fines against a company to up to five years of jail time for its directors and offi cers.

NSF International(NSF),in cooperation with the USEPA, recently evaluated the performance of ADI International's MEDIA 02ÂŽ adsorption media filter for reduction of arsenic in drinking water.

Verification testing was conducted from October 8, 2003 through May 28, 2004. The source water was groundwater. The treatment unit feed water

for the verification test had an average total arsenic concentration of 21 ppb, pH of 7.6, iron up to I.I ppm, man ganese up to I ppm, average silica of 28 ppm and high hardness.

Following pre-treatment (chlorination and pH adjustment of the feed water) the ADI adsorption process reduced arsenic to an average concen tration of 7 ppb over the test period (to 2 ppb at the begirming of the test, to 10 ppb at break-through). In addition, the process reduced iron and manganese in the treated water to 0.068 ppm and 0.016 ppm, respectively.

Did you know that concrete pipe installations may cost less than polyethylene pipe? Get your calculator out.

Polyethylene pipe may seem less expensive than concrete pipe, but add the additional cost of meeting Ontario installation standards—more compacted gravel—and you've got a pipe solution that costs about the same as concrete pipe, but doesn't deliver the same strength, dependability and longevity. And should you encounter structural problems after the fact, the bottom line will have you seeing red.

Do the math. Then specify the solution that's the most affordable after all—concrete pipe.
