Editorial Comment by Tom Davey

Responsibility without powerâ&#x20AC;&#x201D; the burden of environmental engineering

Two decades ago, an article

in Le Monde predicted that professional communica

tors would hold the same social rank that ecclesiastics held in

the Middle Ages. I thought this was absurd at the time, but events have proved the world-renowned French newspaper actually understated the case.

Environmentally, the Engineer ing profession has served Canada better than its people know. Giants such as Quebec's Pal Bourgeois and Western Canada's Bill Hurst, Ontar io's Dr. Albert Edward Berry and Wil lis Chipman, (who was probably Canada's first consulting engineer before the turn of the Century) were light years ahead of society in prom oting environmental protection.

They were also several generations ahead of the Green Movement cur

rently dominating our news media.

Moreover their engineering legacy to posterity was a tangible array of functional

Engineers have developed many projects which protect both the pub lic's health and the environment

A I I #%IAf Ontario municipalities repair about 9500 breaks annuaily. This number is likely to increase along with costs, disruption of service and potential hazards associated with corroding water distribution systems in Canada.

Corrosion is the principal cause of an estimated 20,000 watermain breaks across Canada annually.

How many watermain breaks will occur in your municipality?

In Ontario alone the average annual breaks is an astounding 25 per 100 km.

This results In an annual emergency repair cost of approximately $65 million. It Is further estimated that 15% of the water

supplied is unaccounted for. Current predictions are that break frequency is likely to Increase.

Why is our infrastructure failing?

Soil resistivity, soil contamination, dissimilar metal couples and the extensive use of copper services are major contributors to corrosion. It Is likely to get worse as thinner-walled ductile iron pipe continues to experience a relatively high failure frequency. Without expensive remedial programs, Canada's existing Iron watermain systems will continue to corrode at an alarming rate.

The earthquake brought a spirit of camaraderie to the darkened hotel where Canadian delegates enjoyed a drink by candlelight. Left to right: Ed Pickovnik, Ariat; Dave Fenton, Canadian Drives; and Steve Davey, Environmental Science & Engineering.

The prospect of a Water Pol

was a great success bringing envir onmental engineers and scientists together from across our country.

Everyone knew ofthe earthquake threat but it was one of those things which lurked remotely in the sub conscious; a vague possibility some time in the future, hut not even remotely connected with the reality of this conference.

After three highly successful

days the unthinkable happened - an earthquake reaching seven on the Richter scale. The tragedy was of awesome proportions - the collapsed two-tier highway adding a particu larly macabre and tragic twist.

American emergency agencies res ponded with great professionalism.

I could not help thinking that the earthquake couid easiiy have wiped out a substantial proportion of Cana dian environmental expertise with so

The President of Duratron, Hank St. Onge, his wife Carol, and their Sales Manager Dave Brown were also at the Convention Centre when

the quake began. Duratron specia lizes in pipe protection and, in a most appropriate reflex action, the firm's staff took refuge inside a large pipe at an Exhibitor's stand, the pipe protecting Duratron, some what of a role reversal.

Other Canadians were aston

Gerry Rupke, a PCAO director said at first he thought the rumbling "was an awfully rough subway com ing through". But when the plaster started shaking off the ceiling he decided to get out. "Reality struck

The conference of course was

abandoned and, as we set out to fly home, Tee Shirts - quite artistically done in black, orange and white were already on sale bearing the slo gan 'I survived the '89 Earthquake'.

Clearly the American entrepreneur ial spirit had survived one of nature's deadliest blows and the city had begun its task ofrebuilding nor mal life.

The water supply industry in

the Regional Municipality of Waterloo(Ont.)is rapidly changing. As construction activity on the $93 million project increases, the local water supply industry is being introduced to new terminology. While the terminology may be new,the technologies being referred to have been proven, such as; artificial ground water recharge, intake protection systems with real time raw water quality monitoring

Implicit in the success of the recharge scheme, and continued use of ground water, is the Region's aggressive water conservation pro gram which is concurrently being implemented.

The Region's customers are now

very much aware that water Is a pre cious resource and must be highly valued.

The Mannheim aquifer has in excess of two billion gallons capac ity providing adequate seasonal peaking storage for the Region's needs into the year 2036. When the scheme is fully developed,54 million gallons of raw water can be treated per day and stored in the aquifer in months of high river flows (April, May and October). In summer months, the reserve in the aquifer will be depleted as 37 million gallons per day are extracted from the

Raw water is used for flushing.

The flush cycle begins with air injac tion to fluidize the media bed, expanding it to the full tank depth.

Flushing action continues for 2 to 4 minutes at which time the air is

stopped, allowing the media to float back to its normal position. Overall flushing process takes a total of 4 to 7 minutes. The adsorption clarifier removes up to 95% of the turbidity and suspended solids.

Technology Review HYAN reactor successfully treats MSG wastewaters In China Treating a monosodium glutamate wastewater at a factory in Shanghai, China, a pilot project using HYAN technology has suc ceeded where other systems had pre viously failed.

Designed and patented by con sulting engineers Gore & Storrie,the HYAN reactor treats high-strength waste streams, while converting the wastewater into significant amounts of methane fuel.

As it turns out, the G&S project

developed into two interesting sto ries. First there was the pilot study at the Tian Chu Gourmet Powder

Factory, which proved the effective ness of the HYAN anaerobic reactor

in reducing the strength of a diffi cult and strong organic industrial waste. But there was also the story of communications and ingenuity in the face of the vast distance and

time difference between Shanghai and Toronto - and against the back drop of world-shaking events in China in the spring of 1989.

The pilot project, which began in November 1988, was partially funded by CIDA and followed a trip to China by G&S engineers and scientists. G&S set up the plant and trained the Chinese technical staff

from the Shanghai Municipal Engi neering Design Institute (SMEDI) under the direction of Gore & Storrie's Dr. Michael Yue.

Dr. Yue speaks and writes Chi nese, so his linguistic skills were invaluable. The 12,000 miles and 13 hour time difference were essen

tially not a factor in the work. Daily communication

Toronto

and Shanghai was maintained by telefax and telex, enabling data analysis and interpretation to be effected within 24 hours.

The later stages of the work took place in May 1989, during the stu dent demonstrations in Beijing and

other parts of China. While the eyes of the world were on Tienanmen

Square, G&S associates in Shanghai continued sending their data to Canada by fax and telex, without affecting the project's viability.

The project at the Tien Chu MSG Factory provided valuable expe rience in treating this type of very high-strength wastewater, and con firmed the versatility and effective ness of the HYAN reactor.

Good news for Ask yourself this.."Do my test results balance?. , Are they complete?". or . . . don't you really know!

At MANN AQUA we know! Quality comes first because our expert system says so. And to prove it, we give you all of your theoretical Quality Control data so you can see for yourself just what your water Is or is not missing. It's really quite simple: our computer checks the ion balance. When the cations and anions (-f- and -)are not equal, either an analytical error exists which we'll correct before it leaves the lab, or something is in your sample which has not been tested for; In either case the theoretical conductivity pinpoints the

solution. So if you didn't know what you were missing before . . .

ANNOUNCEMENT

Now you can keep your staff on call while they take compulsory compliance and competence training

P.roper training in occupational health and safety and environmental

technology is fast becoming the more economical option- now that managers are facing increased insurance costs, potential liability claims, and legal prosecutions for not providing adequate or required training.

"Compliance based training for operations personnel is limited compared to the demand," says Peter Van Caulart, Director of Training for the Environmental Training Institute. "It isn't always easy to have key staff attend outof'town courses in order to meet the require ments of legislated compliance."

Environmental Training Institute brings top-notch training to sponsor locations.

Founded in 1987, the Environmental

Training Institute is an independent training resource- serving industry, govemment and municipal sectors. Says Van Caulart,"By taking our training seminars to sponsor loca tions, we provide a much needed resourcewith some added benefits. Our customers

find it's not only convenient, but they save the cost of putting up staff in distant hotels for up to 5 days. And their key personnel can still be on call in case of emergencies.

"Also when local sponsors share the cost of training we have a cross section of attendees

from the municipal and industrial sectors.

The mix of experience and exchange of information can be invaluable."

"We're already building considerable recognition for ourselves with our Confined Space Entry course."

"We founded the Environmental Training Institute" Van Caulart says, "on the belief that the work place and our natural environ ment can be better protected through effec

tive worker training. And effective training includes "hands-on" experience, practical demonstration and competent instruction.

"We exceed the requirements for the Ontario Operators Certificatation Program in many of our courses. And our Confined Space Entry course, which runs for four days with examinations throughout, has earned us considerable professional recognition.

"All our courses are conducted at sponsor locations- we bring training to the workplace to accommodate local conditions. At present we offer courses and seminars in two major disciplines, occupational health and safety, and environmental technology. We'll be glad to send course outlines and sponsorship details to industries and municipalities interested in compulsory compliance and competence training."

Not only has this two analy sis approach been expensive and time consuming, but standard Mass Spectrometry units were unable to

iv) final extract volume adjusted to one millilitre, v) two microlitres of the extract is injected.

Our method improves upon the traditional approach by using the results from a surrogate compound which is spiked into each sample just prior to extraction.

The reported percent recovery of 2, 4, 6Tribromobiphenyl allows a measure of QA for each and every sample, thereby supplementing the method performance shown by Laboratory method spikes. This surrogate spike shows the effects of the sample matrix on the method performance thus providing even a higher degree of confidence in the sample results.

For nearly all samples, a florisil cleanup is not required enabling a major savings in time and improved method ruggedness.

CANVIRO claims analytical breakthrough (continued) still use packed column technology that matured in the 1960's although the move towards the mega-bore fused silica column(0.52mm I.D.)is very evident. CANVIRO Labs uses the state-of-the-art, narrow bore (0.25mm I.D.) fused silica capillary columns in order to obtain further

chromatographic separation and thus select unique peaks representa tive for each cogener series. This method also more efficiently separ ates out the PCBs from any sample matrix.

PCBs are detected by HRGC/MS in the selected ion monitoring mode.

This mode of operation along with custom data reduction programs, significantly reduces the operator interpretation inherent with GC/ECD methods, especially for samples with a significant back ground matrix. Theimprovementin sample to sample consistency is as a result of the strict identification

The use of mass spectrometry also enables the spiking of a compound into the final extract, thus allowing the use of Internal standard quantitation, which adjusts for any run-to-run varia tions in the injection system.

Even in samples having difficult matrices such as paint sludges, the selectivity of the MS and the narrow bore column substantially removes operator judgment calls. An adap tation of the method currently used at the MOE for ECD analysis, allows the monitoring of 8 peaks from each of the 1242, 1254, and 1260 Arochlors. Data are subjected to a routine custom data reduction

program that results in unsur passed operator confidence in iden tification and quantitation.

a small city located 150 km northeast of Regina with a population of 5,200. The City's long term water supply has been from a surface water reservoir on Crescent Creek

just west of the City. This reservoir has a full storage capacity of approximately 4500 dam^ but is only capable of providing approxi mately 420 dam^ on a firm annual long term basis from the reservoir catchment area.

The City has a current annual demand of 850 dam^ and therefore

requires an additional supply source to supplement the current supply during dry years.

Agriculture Canada, Prairie Farm Rehabilitation Act (FFRA) conducted a comprehensive water supply study which recommended that groundwater be used to supple ment the surface water supply. "The

Electrodialysis Reversal (EDR) The EDR reversal system is designed to continuously produce demineraiized water without constant chemical addition

during normal operation, thus eliminating the major problems encountered in unidi rectional systems. The EDR system uses electrical polarity reversal to continually control membrane scaling and fouling.

In this system the polarity of the elec trodes is reversed 3 to 4 times each hour.

This reverses the direction of Ion move

1990.

The EDR treatment process requires pretreatment of the water to reduce iron and manganese levels to <0.30 and <0.05 mg/L respec tively. The raw water has an iron content of 2.0 mg/L, manganese of 0.6 mg/L,pH of 7.5 and temperature range of 7 to 10°C. Oxidation of the dissolved iron

and manganese is performed by feeding potassium permanganate and flash mixing it using a static

brane stack.

The membranes are

stacked vertically and are 457 mm x 1016 mm ( 18 X 40 inches) with approximately 200 to a stack.

As the water flows between the layers of membranes, the cations (Na+)in the solution are attracted to the negative electrode and flow through the cation membranes; the anions (C1-) in the solution are attracted to the positive electrode on the opposite end of the membrane stack and flow through the anion membranes.

Contacts and cooperation between universities and government institu tions (where most Canadian research of this type is conducted) and the pri vate sector, which ultimately com mercializes technological advances, are much too limited to result in the

efficient transfer of technology.

CWWA is ideally positioned to foster these contacts and coopera tion. Its member utilities,stretching from Wahush, Newfoundland to Iqaluit in the Northwest Territories to Greater Vancouver,supply infor mation on needs and successes, and receive news of new technology with great interest.

Some members relay information on local research programs.

Halifax, for instance, has learned a lot in recent years about the best method of protecting new ductile

iron pipe and copper service lines from corrosion in aggressive soil, and has developed an in-house leak detection program believed to be as

good as or better than those availa ble from private contractors.

With its office in Ottawa,CWWA also is ideally located to bring its members' concerns to the attention

of the federal government which is beginning to open pockets of tech

nology-directed funds.

Already,

close links have been established with academies and associations of

scientists and environmentalists, such as the Rawson Academy of Aquatic Science, which can help get specific projects off the ground.

SAMPLE SIGMA...CANADA Liquid samplers combining sample integrity with rugged practicality... that's STREAMLINE™.

STREAMLINE™ innovation includes a patented liquid

sensing system. Unlike other peristaltic pump sam plers, STREAMLINE™ delivers repeatable volumes by automatically compensating for changing lifts. And if the first attempt to take a sample fails due to a plugged

intake, STREAMLINE™ initiates a high pressure purge and tries again. Most importantly, we understand that samplers get rough treatment... and STREAMLINE™ will take it. Electronics are

isolated in a watertight NEMA 4x, 6 housing and the roto-molded polyethylene case is more impact resistant than the ABS common to other samplers.
