Following emotional confronta tions and legal skirmishes with citi zens' groups in Mississauga, where the test burns occurred, the kiln technology was abandoned; a

dial work is estimated at some $46 million. It is a scandal that millions of litres of PCB-contaminated wastes still remain untreated

when a viable technology exists which will safely destroy them. More than a decade ago Canadi ans developed an ingenious dis posal process which used cement kilns to incinerate PCBcontaminated wastes.

The technology resulted from a brilliant combination of federal and

provincial scientists, working with private sector engineers and scient ists from Ontario Research Founda

tion.

But this truly innovative

scheme was stifled over a decade

ago when the project was aban doned in response to pressures from Mississauga City Council and pro test groups.

Scientific experiments proved that

PCB-contaminated

wastes

could be safely incinerated when used as fuel for rotary kilns during cement manufacture. Now burning PCBs can he a risky business as the chemical must be incinerated at

extremely high temperatures before it is safely destroyed. But rotary kilns during cement manufacture operate at extremely high tempera tures which greatly exceed those required for safe disposal. Moreover, the PCBs are detained in the kiln, well in excess of the time needed to ensure total destruction. This'com

bustion duration' is especially important as partially burned PCBs are extremely hazardous when released into the atmosphere. Additionally, the high tempera tures also destroy highly toxic dioxins commonly found in other incineration modes. There are other

advantages. By using PCBcontaminated liquid wastes during cement manufacture, toxic liquids are transformed into valuable fuel -

toxic

waste-chlorinated-

hydrocarhons such as polynuclear aromatics (PNAs) which still pose serious disposal problems. Today, people cannot believe that such a promising technology was abandoned, if indeed it was both effective and safe. Let us examine the facts. Environment Ontario's own

scientists said that disposal by the cement kiln process des troyed some 99.986 percent of PCBs. The remaining chemicals were

broken

down into low

molecular weight solids which were harmlessly absorbed into the cement. During the experi ments scientists could find no

trace of PCBs in the flue gases, the cement clinker products, or the dust collected from the flue gases. There is one final bonus which

led one engineer to say this was 'an engineering marriage made in heaven'; kiln incineration of PCBs

actually had a beneficial effect on the cement being produced. Unques tionably the process could have been further improved through research and development, had the technology been implemented.

overwhelming scientific evidence. One Environment Ontario expert repeatedly stated that alternative technology offered no better safe guards to the problems of PCB dis posal. He was hacked up by Environment Canada scientists

who spoke up vigorously in support of the technology at technical meet ings; but to no avail. Apparently in the appeasement business, complete destruction of toxins while saving vast amounts of energy was not enough; so the cement kiln technology was put in limbo. Mississauga had its little Munich - no PCBs in our time - but

for several years millions of litres of untreated PCBs piled up all over Canada.

Finally there is the ultimate irony. The Ontario Waste Manage ment Corporation, having spent millions of dollars investigating various waste disposal options in Europe and North America - with the most scrupulous concern for long term environmental effects will almost certainly employ an advanced rotary kiln to effectively destroy industrial wastes. But OWMC's kiln will not harness the

valuable thermal properties in the wastes to make cement as it inciner ates toxic wastes.

Polling is a natural extension of our democratic institutions in our

Opinion research can be particularly useful in understanding public views on topics such as the environment. Why? Scientists and professionals need to be experts and well-trained in the environmental sciences in order to

carry out their jobs. The public may be just as concerned about the environment, but have a very differ ent perspective. Typically, the lay public is less informed and lacks the 8

major public affairs research firms. Since 1970 we have been doing public opinion research in many areas and for a broad range of clients, includ ing governments and private cor porations. One of the most striking developments in the past five or six years is the emergence of the environment as one of the top issues of concern to the Canadian public, right up there with key economic issues such as jobs. Not surprisingly, many of our corporate and government clients have become increasingly interested in the public's views on environ mental issues and we find ourselves

hazards.

Experts tend to rely on quantifiable information, such as estimated probable deaths per million in the population. The public relies much more on qualitative criteria, such as whether or not a hazard is common (traffic accident) or catastrophic (plane crash), or whether or not the effects are immediate (tornado) or delayed (asbestos). It is this divergence in perspectives-these two solitudes-that is be

Whether environmental profes sionals consider the public's per spective to be valid or misguided, you need to be aware of and under stand how the public views environ mental hazards.

And this fact is

already widely recognized. Today

syndicated opinion research service devoted exclusively to environ mental issues. By syndicated we mean that a number of clients sub

scribe to our reports and share the cost of this one-quarter million dollar annual research program. The Environmental Monitor is a

quarterly survey of 1,500 Canadians. Every three months we survey Canadians on key environmental issues of interest to our subscribers.

Our third survey, which is now underway, focuses on the transport and disposal of waste, in which we are probing such issues as public perceptions of the relative safety of waste management alternatives, such as landfills and incinerators, as well as the adequacy of current safety standards for hazardous waste transport.

First, our results very conclusive ly show that the Canadian public is very concerned about the environ ment. Whereas in the past environ mental

Equal numbers of the public say they are very concerned about toxic chemicals (69%) and water quality (68%). Somewhat fewer are very concerned about air quality (68%), municipal waste disposal (57%), depletion of natural resources (53%), transportation of dangerous goods (49%) and nuclear power (44%).

AUTO-CLEANSE.

Another new idea from Rygt. ■ Provides clean station environment.

■ Improves operating efficiency. ■ Reduces maintenance costs.

■ Easily retro-fitted to existing Installations.

Flygt's new Auto-Cleanse® System solves various problems thiat arise in many pump stations. Ttie system con

sists of three unique components: an Adaptive Pump Control (ARC) unit, a powerful Flush Valve and the patented NevaClog® impeller. The ARC controls all pumping operations to match the rate of flow. Because it works without a fixed start level,

it prevents the accumulation of grease and solids on the sump wall at any fixed water level. The Flush Valve automatically eliminates the build-up of sludge on the sump's bottom. Along with the ARC,the Flush Valve also inhibits the formation of floating crusts.

The patented NevaClog® impeller ensures clog-free flow of highly charged sewage.

The Flygt Auto-Cleanse® System keeps the pumping station free from odour, sludge and grease deposits. It can readily be retro-fitted into existing Flygt equipped pump ing stations. Best of all, because of reduced station mainten

ance costs, the system pays for itself quickly! For complete information on this

new Auto-Cleanse®

System, contact your nearest Flygt representative and ask to see the

increasing the tax rate? To answer these questions, The Canadian Water and Wastewater Association needs to know how much water is deli vered to customers. This is

essential for the use of perfor mance indicators for cost con

trol and to place the cost of service directly with the user. Yet, despite popular support for conservation, user pay and modern management tools of performance indicators and loss control, there remains widespread resistance to universal water metering.

Currently, about half of munici pal water supply customers are on metered systems. The introduction of metering to unmetered systems is undeniably costly. It has been esti mated at between $175 and $250 per household. There undoubtedly are systems for which the costs will out weigh the benefits, even over a very long period of time. There are oth ers, however, where benefits clearly outweigh costs. Avoidance of capi tal costs for new water and waste-

water capacity is probably at least twice as great as the operating cost savings and is a major factor in determining the pay-back price.

To help system managers and owners determine whether meters

In October, $50,000 was obtained and work is now underway. The first phase will develop the tools needed to analyze costs and benefits to a given system of instal ling meters. The work has been divided into five components:

From promotion of the use of the assessment tools, CWWA hopes to develop programs that will assist systems which could benefit from metering and to proceed with instal lation programs. This will entail working with system owners and managers, provincial authorities, and also with meter-related industries as well.

CWWA is pleased to receive Environment Canada's support for this first component of its proposal for a comprehensive study of appropriate pricing of municipal water and wastewater services in Canada. We believe that informa

tion from the metering project, as well as the process of working with the municipal water and wastewater industry, will bring us closer to our long-range goal - to ensure that municipal systems are

planned, built and operated in the most financially, as well as environ mentally, sound manner feasible. The current interest in universal

metering primarily is a result of increasing demand and the need for good management practice, cost control and cost avoidance.

However, ultimately the impact of increasing water supply demand and development pressure will lead to a need to conserve valuable capa city in the wastewater systems. As mature sewer systems reach design capacity, the need for infiltration reduction and water consumption reduction will become even more

important.

Ms. Kates estimated that using botttled waters at $6.50 per 18 litres could cost $500 annually for a family of four. This works out to approximately 36 cents per litre or approximately $10 per week for the family. Municipal systems can deliver some 5,000 litres of treated tap water, to the same house, for about $2.50 per week or .05 cents per litre. All figures are approximate as some municipalities charge much less than $2.50 per week and the price of bottled waters varies widely. Depending on both the brand and size of the containers, the CAC report states that bottled water prices range from about 35 cents to almost a dolllar per litre.

She goes on to say:As our water becomes pro gressively less safe to drink, our survival is threatened.

Ms. Kates stated, without pre senting even fragmentary evidence, that the water supply comes more and more to resemble a sewer. Per

Everything... when that name is

Sewers and water pipes in the older parts of many cities are deteriorating badly. Original brick, clayware, concrete and castiron pipe in frastructures are corroding and collapsing at an

alarming rate.

Traditional methods of repair, involving excava tion and replacement, have proved both prohibitively expensive and extremely disruptive to traffic and

pedestrians. The cost factor and enormity of the task have left regulatory agencies and municipalities with an almost insurmountable problem. Similar difficulties are also being encountered in

modern industrial and manufacturing concerns. Gas, petro-chemical and other process industries are faced

with lengthy and expensive shut-down every time they need to replace corroded and leaking pipes, located underground or in other inaccessible areas.

In 1971 a British engineer, Eric Wood,invented a revolutionary way of repairing damaged pipes. The process allowed existing pipes to be made sound by relining them while still in place - hence the name Insituform. His invention was timely. By cutting out the major expense factors associated with conventional pipeline repair or replacement (i.e. by excavation), Insituform offers considerable direct savings. An indirect bonus is gained through the virtual elimination of disruption caused by large-scale excavation and its accompanying dirt and noise. Another important factor is the saving of time, which can be particularly critical in an industrial situation. The system can be used on otherwise inaccessible sites and installation takes as little as 24 hours to

complete. Dubbed "a pipe within a pipe", it provides much more than just a lining. When in place, new Insituform tube actually increases the structural strength of the original pipe, and will bridge gaps in broken sections. Not only can it improve flow capac ity, owing to a smoother pipe wall, but it is also resist ant to abrasion and chemical corrosion.

Since its first commercial use, in 1973, Insituform has been used successfully in over 40 countries. Over

2,000 kms of pipe have been renovated by the patented process, equivalent to the distance from London to Leningrad or Paris to Athens. As with most great inventions,the system is simple in operation. First, the site is surveyed and a full assessment of the damaged pipeline is produced, pro viding details of the internal dimensions and profile. From this basis the tailor-made Insitutube can be

manufactured. Existing connections are also premeasured and recorded at this stage. A tube, com posed of a polyester-fibre felt sleeve, is coated on the outside with polyurethane and impregnated from the inside with a liquid thermosetting resin. This Insitu tube, tailored to the exact diameter and length of the damaged pipe, is inserted into the pipeline through an existing manhole or other access point. (Cont'd.)

The McAvity name on our hydrant is our customer's guarantee of operational excelience. It's been that way since 1903 when we first began manufacturing hydrants for the Canadian market.

It remains that way today — as evidenced by our contemporary-styled M-67 hydrant, offering proven traditional features plus the latest innovations in design, materials and manufacturing. The McAvity M67 is your assurance of: • A superior, four-section breakaway flange, for quick on-the-spot repair • Needle bearing gives minimal operating torque • Bronze-to-bronze contact, between seat and casing, that ensures easy removal of the seat • Lubrication access without dissassembly • The M67 is manufactured to meet, or, exceed, AWWA G-502 specifications and is also U.L.C. and F.M. approved.

The Human Energy Behind Nuclear Energy Dr. Eva Rosinger is the Director, Waste Management Concept Review, with Atomic Energy of Canada Limited (AECL). She is responsible for managing ail aspects of the review of AECLs concept for used nuclear fuel disposal. Dr. Rosinger has an M. So. degree in Chemical Engineering and a PhD in Chemistry, and has been involved in the radioactive waste program since 1976. Dr. Rosinger is seen here at the used fuel storage bay at Gentiiiy 2 Generating Station in Quebec.

"The nuclearindustry hastaken responsibilityfor its used fuel from day one. We do know how to handle it. Used nuclear fuel represents only a small fraction of all toxic wastes produced by industry."

"Nuclear reactors produce very little used fuel. The total amount in Canada by the year 2000 would fill only three Olympic size swimming pools." Permanent Disposal "Since 1978, members of Canada's scientific and engineering community, government depart ments, universities and private industry have been working together on a multi-barrier concept of disposal.

The new process has applica tions in many industries where H2S gas is an unwanted by product, but especially in the treatment of 'sour' natural gas or crude oil, according to Prof.

mineral slurry by forcing air into the slurry and allowing the hubbies that rise through the slurry to carry the minerals to

J.W. Smith.

the surface. (One way to visual

This new process is especially important to Alberta, Canada's primary gas and oil producing province, because half its sulphur emissions come from natural gas treatment plants. Current technologies to remove H2S are expensive, com plicated and may only reduce the gas to just below legal levels.

ize a flotation cell is to imagine

These levels are well above the odour threshold and result in

complaints from residents living near the treatment plants unless the residual gas is burned. Burning H2S, however, produces a sulphur emission which adds 40

to acid rain.

To build their system. Profes sor Smith and students Bob Barton and Tim Giles started with a model of a flotation cell similar to those used in the

mining industry. Mining companies use flotation cells to recover minerals from a rock/

an enormous kitchen blender.

The glass portion of the blender constitutes the flotation cell; the chopping blade is comparable to the cell's impeller, which draws air into the slurry and creates the hubbies that carry the miner als to the surface). Professor Smith has modified

the standard flotation cell by filling it with a highly active catalyst that speeds the conver sion to water of the hydrogen in the H2S. At the same time the

sulphur in the H2S is converted to solid sulphur, which floats to

the surface of the cell where it can be skimmed off. He also increased the amount of natural

gas being drawn into the flota tion cell to more than twice the amount of air intake used in the

mining process. The bubbles of natural gas created by his system are tiny and highly sheared by the speed of the impeller. As a result,there is better contact with the catal

yst and thus faster and more efficient oxidation than in con ventional contactors.

The process will pay for itself. Smith says, in plants which can extract and sell more than 10

tonnes of sulphur per day, although it will most likely be used in smaller applications where its compact size is important. In pilot tests, the process has been demonstrated to require less capital expenditure and lower operating costs than cur rent methods. Unlike other pro cesses, Smith's invention does not get clogged by impurities or recovered sulphur.
