By Tom Dauey
A Hamlet without the Prince —
or an omelette without eggheads?
Our local baker used to bake real bread, not the
counterfeit mush which imitates the staff-of-life
while tasting like damp cotton wool. His whole wheat loaves were baked
in ovens; they were a feast to the eyes, the olfactory senses and the palate. Best of all you could savour them without sin, for his bread was good for you. One day I noticed the loaves were coming out of the ovens much dar ker than normal. They still looked delicious, hut I asked the baker if he had changed his ingredients? He answered his bread was unchanged, except that he now added a little caramel dye. Why? "To make the loaves look more natural!", he exclaimed.
I realized then that we had gone from the Age of Aquarius to the Age of the Vicarious. Culinary cosme tics were being used to fake what was already the real thing. Literally and metaphorically this was a deli cious irony; the intrinsic was being
Minister Ruth Grier listed 25 groups which she has invited to participate in the Advisory Committee for her proposed Bill. Lawyers predominated with four groups advising the Committee; in fact legal representation comprised an astonishing 16 percent of the Advisory Committee. With such generous input from this learned profession, this Bill might yet emerge as The Lawyers' Welfare Act.
Other groups included Green peace, Friends of the Earth, Pollu tion Probe, Northwatch, Energy Probe, Great Lakes United and the Federation of Ontario Naturalists, all activists to be sure,but disparate in their aims and objectives. Some combine impressive scientific exper tise with genuine altruism; a few are Luddites hiding their deep suspicion of all technology with green makeup.

Federation,the Air and Waste Man agement Association(AWMA)and the Ontario Section, American Water Works Association(AWWA). With a combined history total ling some 200 years, these groups comprise some of the most expert and experienced environmental talent in the country. They are conspicuous by their absence in the proposed Advisory Committee. If this is not exactly a Hamlet without a Prince, then it might be an ome lette without eggheads.
There are many other examples. Recently in Florida, a woman, on observing a magnificent sunset, tinged with the magenta hue of the sub tropics, exulted that the view was "just like Technicolor". The stampede to embrace all things Green has further blurred the distinction between perception and reality. In environmental situa tions, public perception is frequent ly distorted by certain media reports and newscasts written by scientific illiterates.
when typhoid and other lethal water borne diseases decimated popula tions in Ottawa and Toronto. Such sicknesses are now rare events on
this continent,a fact due more to the water treatment professionals who removed the sources of the diseases, rather than the medical professio nals who treated the effects.

hiding their deep suspicion of aii technology with green makeup. One Canadian figure who fought tenaciously for better water quality was Dr. Berry, a world renowned scientist and engineer and the only person ever to be elected president of both the AWWA and the WPCF.
Seven decades ago hefoughtfor bet ter drinking water and waste treat ment against political apathy and vested interests. It is doubly ironic that Mrs. Grier's ministry has igno red the expertise available from the environmental professional associa tions he once spearheaded in Onta rio. For her ministry was created from the former Ontario Water Re sources Commission which Dr.
Berry dominated for many years as its top scientist and chief engineer. The legacy of environmental expertise from Dr. Berry and other pioneers is still available from the professional groups he led so many years ago. It is sad if Mrs. Grier is unaware oftheir existence. It will be

Air
Pollution
By Keith C. Heidorn. PhD.. ACIVi'
The Three Ages of Air Pollution Regulation
Regulation of air pollution
has evolved over history through three major phi losophies. Initially, and for much of man's history, the phi losophy of air pollution regulation was the Age of Ignorance. By the turn of the Twentieth Century, the seeds of the second age, the Age of Dilution were sown.
But as we
began to realize that the Earth's environment had only a finite capa city to absorb the wastes of man's activities, we were forced to develop a new philosophy and bring in the third age, the Age of Exclusion. The Age of the Philosophy of Ignorance(the use ofthe term "igno rance" derives more from the verb
"to ignore" than from "ignorant") evolved through three phases — phi losophies which still prevail in the thinking of some. The first phase was characterized by the phrase "Everybody has the run of the river". That is, all have an equal right to dump whatever they wish into rivers, the seas and the atmos phere to the full extent of their abi lity. Later, the prevailing thinking was "Pollution is the sign of a heal thy industry"(i.e. a sign of wealth) and, as a result, most governments took no legislative action. In a last ditch attempt to keep the Philoso phy ofIgnorance alive,the head-inthe-sand attitude of We need more studies was instituted.
The first serious attempts by gov
ernments to control air pollution came with the Age ofthe Philosophy of Dilution and its catch phrase "Dilution is the Solution to Pollu
tion". In this Age,legislative action was taken to reduce the concentra
tion of pollutants locally in an attempt to avoid acute health effects in the population or severe damage to crops,livestock or materials. This philosophy often instituted controls such as taller stacks, greater plume rise and greater distances to sensi tive receptors rather than pollution control devices or process reform. While such measures dramatic
ally reduced the local concentra tions of target pollutants, it was soon apparent that some of these measures brought on other prob lems such as acid precipitation. As the technology to measure trace com pounds improved and medical and biological research found adverse effects from a growing number of chemicals, it became obvious that Exclusion is the only Solution to
Pollution; thus ushering in the cur rent Age ofthe Philosophy ofExclu sion.
Under this philosophy, legisla tion has been introduced to reduce
emissions either in the stack, at the process level, or by banning a che mical from use. The problems of long-range transport, bioaccumulation, chronic effects and global impacts have come to the forefront, not only in the thinking of the regu lators but in the minds of the popu lation at large. The first air pollution regulation in Canada was enacted in Toronto in 1907 to restrict the combustion of
fuels. Ontario's first legislation was the Damage by Sulphur Fumes Arbi tration Act which did nothing to control or restrict sulphur emissions but recognized the economic impact
fined a method for observing black smoke. In 1963 and 1967, revisions to the Act gave the Province control over air pollution matters to ensure equality ofregulation across the Pro vince. The revisions also establis
hed the Certificate of Approval pro cess.
Also in 1967, the regulation now known as Regulation 308 was first enacted. This regulation defined point of impingement air quality standards and the mathematical
models by which to calculate the point of impingement concentra tions. In addition, the Air Pollution Index and the desirable ambient air
quality criterion were defined. The passage ofthe Environmental Protection Act in 1971 consolidated
the legislation for air, water and waste under the newly created Ontario Ministry of the Environ ment. Included under this Act was
In order to ensure
that the Installed control
equipment performs to standards, In-stack
emission monitoring may be mandated.
Regulation 308, the currently enfor ced regulation for the control of air contaminants. It is,in large part, a declaration of the Philosophy of Dilution. While not explicitly man dating the use of pollution control equipment, it may be argued that the Regulation, with its requirement that sources meet point of impinge ment concentration standards,does force the use of pollution control equipment in some cases. However, as written, the act allows for stack
ofpollution damage and the need for redress.
By 1955 the Province of Ontario, now conscious ofthe effects of pollu tion, formed a Select Committee of the Legislative Assembly to review air pollution. Although the findings concluded that air pollution was a serious health hazard, that pollu tion was a problem to farmers and that pollution control was worthy of attention, the 1957 report was typi cal of the later phases of the Age of Ignorance. The report recommen ded control ofrailroad and shipping pollutant emissions and the prohi bition of domestic incineration. It
also fingered the internal combus tion engine as a major source of pol lution. It is interesting to note, however, that industrial sources were given a back seat to transpor tation sources in this report.
In the Select Committee report were the seeds of pollution control. In 1958,the passage ofthe Air Pollu tion Control Act gave emission con trol responsibility to municipalities, outlined an appeals process and de

height to be increased as a means of meeting the point of impingement standard. While increasing the stack height reduces local concen trations, it does little to reduce the overall burden on the environment.
In the best of circumstances, this rather uniformally increases the concentration ofthe pollutant over a wide area. However,for pollutants which react together in the atmos phere such as the precursors to pho tochemical smog or acidic precipita tion,increasing stack height may be more detrimental to the environ
ment than lower emission heights. Regulation 308 also implicitly addresses the pre-emission control of particulate matter through the control of visible emissions from a
stack. The means or degree of parti culate control is not set forth other
than the prohibition that the efflu ent plume must not exceed a maxi mum darkness or opacity to light. continued overleaf

potentially adverse levels under weather conditions conducive to pol lutant buildup. However, as more knowledge of the effects of environ mental pollution was acquired, it became apparent that the regula tion had no long-term or long-range considerations,did notinclude depo sition of pollutants or their chemis try. The permitting of a source by Regulation 308 is taken in isolation of other sources around it using mathematical models considered to

rating system which is designed to account for changes in the know ledge base. The basis for a chemi cal's rating will include its toxicity, persistence and bioaccumulation in the environment as well as its poten tial for transport through the envi ronment.
Controls may be strict — perhaps either the lowest achievable emis
sion rate(LAER)for the most hazar dous pollutants or the best available control technology economically achievable (BACT-EA) for pollu tants of lesser hazard. In order to ensure that the installed control
equipment performs to standards, in-stack emission monitoring may be mandated. Whereas Regulation 308 was originally intended for stack emissions, CAP will cover all emission sources including those
emissions considered as fugitive sources, those from which pollu tants escape from vents, doors,con veyors, etc.
The current Certificate of Appro val, strictly an approval to con struct, is issued for the life of the operation approved, barring altera tions to the process or emission mechanism. Under the proposed CAP Certificate of Approval pro cess, a Certificate of Approval for Construction will be followed by a Certificate of Approval for Opera tion which, unlike its predecessor, must be renewed every 10 years. In order to ensure that even with
the required emission controls, ambientlevels ofall pollutants resul ting from the accumulation of emis sionsfrom a number ofsources with in an airshed do not exceed ambient
air quality standards, state-of-theart mathematical models will be used to estimate airshed concentra

Water leakage is a con

A water leak detection program normally in volves some type ofsonic evaluation which depends on an operator's abil ity to hear and identify leak sounds on the water mains. Sonic leakage detection is hased on the principle that high pressure water leaking from a water system through an opening or break in the main into an area of atmospheric pressure sets up

In recent years computer hased "corre lation type" instruments have gar nered prominence. Applied correct ly, these instruments can provide additional capabilities for an expe rienced operator. The advantages ofleak noise cor relation over previous sonic methods are numerous, particularly in the pinpointing application. The correlation principal uses sound similarity, not the position of maxi mum leak noise intensity, as the basis of operation. Water or any other fluid, escaping from a pressu rized pipe provides a characteristic noise which is propagated at a con stant velocity in both directions away from the leak location.

This sound is transmitted along the

ding the pipe but the energy is quic kly dissipated. This first sound is considered the search sound and is
useful in systematically searching an area to determine the presence of leaks. By using highly amplified sonic instruments these sounds can
be heard on valves, hydrants, curb valves and other contact points on the system. The second sound created by a water leak is often referred to as the
impact sound. This is caused by the leaking water, under high pressure, striking the soil in the leak area.The third sound is the fountain sound, which is caused by water circulating in water, usually in a cavity in the soil adjacent to the leak. Both the second and third sounds are in the
times. The computer based correla tor then progressively delays one signal relative to the other while continuing to compare the simila rity between them. This enables the correlator to measure the difference in travel time ofthe leak noise to the
respective sensors. By determining the velocity of sound for the particu lar pipeline under test and using the distance between the sensors, the correlators can accurately compute the leak position. A built-in formula allows the correlator to compute the actual distance ofthe leak from both
sensors and displays the distance on a highly visible screen. Effective water leakage detection programs are as much dependent on proper procedures as on good qua lity instruments. Leak detection personnel must have a knowledge of the system design and pipe mate rials as well as an understanding of the influencing factors to sound attenuation.

system. For effective results, leak detection personnel must be flexible in their approach and be prepared to adjust procedures depending on the design and field conditions encoun tered. For optimum results, a fourstep approach is recommended when conducting a water leakage detection program. Step one is the leak search proce dure which involves systematic lis tening at all contact points, such as hydrants and valves, on the water distribution network.
When sec
tions of non-metallic piping are pre sent in the search area, it will be necessary to listen at grade directly over the pipe with a combination of soft surface and hard surface micro
phones. The test interval will nor mally be about one metre or every step along the pipe run. Listening at grade will also be necessary on long sections of metallic pipe withoutcon tact points. Sounds at suspect loca tions noted during the search pro gram will be logged as to location, frequency and intensity. Step two involves a more detailed evaluation of the suspect locations and is normally scheduled at night when water use, traffic noise and other ambient background noise is at a minimum on the system. This is the verification procedure and esta blishes the actual existence of a leak
and its approximate location. In numerous situations, the leak can actually he pinpointed during the verification program. Steps one and two are normally referred to as leak search operations.
Steps three and four are normally referred to as leak pinpointing opera tions. Pinpointing is defined as establishing the actual leak location and is not yet an exact science. Well trained leak survey personnel will achieve a high level of success but some dry holes will be inevitable. Higher levels of success are being realized with the advent of leak cor relators based on the leak noise cor
relation technique. Step three is the actual leak pin
pointing procedure and normally involves the use of a computer dri ven water leak correlation unit. The actual location ofthe verified leak is

by a variety of procedures using the portable search instruments. In some situations, the confirmation
procedure is more accurate and adjustments are made to the corre lated location. The intent of step four is to reduce the chance of dry holes and permit leak repairs in a one cut operation. Once step four is completed, the leak location can be marked for repairs and duly repor ted on the proper reportforms.When leak sounds can only be detected at one contact point on a water system, correlators cannot be used to pin point the leak source. This is com monplace on non-metallic systems which are poor conductors of sound. Several correlator manufacturers
provide hydrophone sensors as optional accessories. These sensors are inserted into hydrants with spe cial adaptors and detect leak fre quencies transmitted directly in the water. Leakage frequencies or sound waves, travel well in water and can often be detected a conside rable distance from the leak source. Sound waves from the same leak
travelling along the pipe wall or through the soil,tend to attenuate or diminish rapidly as they move away from the leak source. Hydrophone sensors offer improved sensitivity to leak noise detection as the sensor is
inserted directly into the water core. The correlation procedure to pin point leaks is quick and easy to use. Valves or hydrants indicating sounds on either side of the suspec ted leak position are located and sensors attached. If accelerometers
are used,these are attached magne tically to the outside of the pipe or fitting. If hydrophones are being used, they are connected to the hydrant and the valve opened. The pipe distance or length between the

detected by traditional sonic and correlation procedures. These leaks often occur as hydrostatic test fai lures during new construction or upgrading projects. They tend to occur more frequently when nonmetallic pipe materials are being used. A tracer gas procedure using helium has exhibited a high level of success in locating such leakage. The procedure involves dewatering the section under test and inserting a mixture of5% to 10% helium in air at one end of the section. A relief is
kept open at the opposite end to allow the helium to flow through and fill the section. When helium is
detected at the reliefend,the reliefis closed and the section is pressurized to a pre-determined pressure. Helium is one of the true noble gases being completely inert and non-toxic. It can be used on any type of enclosed continued overleaf 19

The most costly waste of treated water is leakage on below ground water distribution systems. Un accounted-for water in the range of 10% to 30% is commonplace on many municipal water systemsin Canada. Lossfactors ofthis magnitude would bankrupt many industries as this represents a direct loss of finished product. Our apathy towards water over the years has resulted in a complacent acceptance of such losses as being normal and there fore acceptable. This attitude must change as we can no longer allow the lifehlood of our environment to

What MISA has achieved — what lies ahead A former Director of Water Resources
for ttie Ontario Ministry of ttie Environment, Jim Bistiop piayed a major role in the development of the Municipal & industrial Strategy for Abatement. ES&E asked him to review what has become one of
Canada's most progressive pieces of environmental legislation.
Ontario's MISA program

It began with a sustained attempt to open up the regulatory process to the public, to industry, and to the vari ous environmental public interest groups. This process, while admi rable in its intent, inevitably resul ted in a regulatory process that could not be all things to all sides, and inevitably disappointing to some degree to all concerned.

The main issues that led to MISA what philosophies were incorpora ted into it, and what it was intended were: to accomplish.

In early 1985 the Liberals were elected, in a coalition with the New Democratic Party and Jim Bradley became the Minister of the Envi
ronment. He brought with him a zealous commitment to environmen tal care and an action-oriented team
of well-prepared, experienced, exe cutive assistants. It was clear that
the time was right for some new approaches to environmental man agement.

This need crystallized in August 1985 when Dow's Samia operation lost 55,000 L. of perchlorethylene into the St. Glair River, and Ontario added the blob to its environmental lexicon. This event also fast-tracked
MISA into being. While June 1986 was the official birth month of
MISA, August 15/85 was the like liest date of conception. MISA was now well and truly launched. MiSA'S MISSION

With the monitoring regulations now promulgated for the industrial sectors, MISA is now entering the critical phase — setting effluent limits. To speed up the process, MOE decided to adopt a generic issues resolution process. This is possible because of the technical and procedural insights gained from the consultative approach in the development of the Monitoring Regulations. From the extensive dialogue with each ofthe 10 JTC's,it is clear that there are many issues that are common to all sectors, and rather than deliberate each issue at

away from regulatory programs in Ontario.
Early in 1990, the Liberal Cabi net appeared to be divided over the economic and political importance of environment generally and the Ministry ofEnvironmentin particu lar. This led to a well-reported rift

Using economic means for environmental ends
Whenitcomesto economics, there are basically two
kinds of environmental ists. On the one hand there are the
"back to the earth" group, some times typified by the attitude ofCBC television luminary David Suzuki. Apparently, this group wants no thing less than to shut down the modern economic process as we observe it and to retrench to a less industrialized and less active eco
nomy which would produce much less but consume much less of our
natural resources and other things. In fact, recognizing that many peo ple in the world are still at a subsis tence level, some of these environ mentalists claim we should stop the level of economic growth in the world where it is now and redistri bute what we have rather than
There are other indicators that environmentalism and economic
advance are reconcilable. Larry Solomon advocates private owner ship of forests as the only way to effectively save them and the envi ronmental amenities that they pro vide. That privatizing forests does not necessarily rule out economic development but only ensures a rational approach to the utilization ofthe resources can be seen from the activities of the National Audubon
Society in the United States. The society has a beautiful wildlife sanc tuary in Vermilion Parish, Louisi ana,called the Rainey Preserve.The main purpose of the preserve is to provide protection for migrating snow geese, but it also provides a habitat for other birds, alligators, mink, and armadillos.

The Rainey Preserve also has stocks of natural gas. Rather than arguing against the exploitation of this resource as the Audubon Society
has done in other areas where the
natural gas has existed on publicly owned land, in its own reserve the society worked out an arrangement with a private company to drill for the natural gas. The reason was quite simple. At the peak of the last oil price boom, natural gas produc tion from the reserve was providing about $1 million per year in income that the Audubon Society could use to pursue other environmental objec tives. A clear example of a reconci liation between economic and envi
ronmental objectives. Close scrutiny by the society en sured that the drilling caused no negative effect on the environment and apparently caused no change in the behaviour ofthe geese which are co-users of the reserve. There are
other examples in Michigan where the society has collaborated in pro jects on its lands. Canadian envi ronmentalists could take a few

The impact on Lake Ontario was difficult to predict. Monitoring in the lake indicated that while the young mussels are now present along much of the shoreline, the densities, parti cularly on the Canadian side, were less than may have been expected. Higher densities and older mussels appeared at most commercial ports and docks, which may mean an acce lerated infestation rate in 1991, hel

Canal, have all reported significant numbers of zebra mussels in their waters.
All indications are that by late 1991, few areas in the lower Lakes will escape the effects of the mussels and much of the lower Lake Huron
and Michigan shorelines, particu larly along shipping channels, will also see mussels. Lake Superior, Upper Lake Michigan, and Huron may be the only major areas to escape the full impact of the mussel
in 1991 with only minor infestation of shallower embayments near ship ping ports. RESEARCH EFFORTS
When the impact ofthe zebra mus sel was initially felt in 1989, little information was available regarding its biology, or protocols for its control in industrial or municipal settings. The use of chlorine was well docu
mented, however, in fairly general terms which often failed to discuss
the affect of temperature, pH, and other water quality parameters which greatly alter effective treat ment concentration and duration. Initial treatments in North Ame
rica were based on European litera ture; however, reports of effective chemical concentrations vary from as low as 0.5 ppm total residual chlo rine to greater than 2 ppm in a wide variety of protocols from continuous to pulse dosing. This information
only added to the confusion. As industry became aware of the potential problems associated with the mussel, requests for chlorination of service water systems came in to the Ontario Ministry of the Environment with increasing freq uency. Initially these treatments were granted approval on an expe rimental basis in order to learn more
about this process and to keep badly

Physical control ofthe zebra mus sel is usually difficult. Heat has been attempted at several US utili
regard to the zebra mussel problem. However, following a zebra mussel symposium held at the University of Guelph, both Ministry of National Resources and Agriculture Canada began to move. The result was that the MNR was now the lead agency in dealing with this problem and that Agriculture Canada has dee med the zebra mussel a pest and chlorine as the only chemical regis tered for its control. The concerns about the effect of wholesale use of chlorine and the
potential for environmental damage, led the MOE to require industry to apply for a Certificate of Approval for dechlorination facili ties at sites using this chemical for zebra mussel control. Chlorine must now be controlled
in industrial effluents, at virtually undetectable levels (.01 ppm requi rement,.002 ppm objective). While attaining these levels is relatively simple, the technology to analyze for residual chlorine to these levels in industrial effluents on a conti
nual basis, has been difficult if not impossible to find. Crab sampling for amperometric analysis under clean laboratory conditions appears to be a most reliable method for industrial sites. The concern about the formation
of chlorination by-products such as trihalomethanes and other chlori
nated organics, and the difficulties with meeting MOE guidelines, has led industry into the search to mini mize chlorine use and to find alter
nate chemical and physical means to control the mussel.
Ontario Hydro, with an obvious vested interest, has been the lead agency in Canada since early 1989. Hydro, as part of a larger Lake Erie utilities group which includes many utilities in the US, has initiated research on just about every concei vable avenue for zebra mussel con
trol. Much of this work is on-going and the results are just now being
put together. However, the list of potentially useful chemicals in cludes; Hypochlorite, Chlorine diox ide,Chloramines,Potassium perman ganate, Bromine, Hydrogen per

Those that can, may be able to keep some areas mussel free without the use of chemicals.
New research in the area of hydroacoustics seems promising. Several frequencies have been found that will cause mortality in zebra mussel larvae and will crack the shells or
cause migration of young adult mus sels. Further research is underway to upscale these devices. The use of electricity to keep in take structures and grates mussel free is also under investigation,how ever, field testing has yet to he com pleted.
In addition to these physical and chemical controls, a number of new or newly named surface coatings have been marketed to prevent mus sel infestation. For the most part, these surfaces appear to slow the infestation rate;however,physicalclean
ing is still eventually required. BIOLOGICAL MONITORING The tremendous amount of re
search activity may soon provide a clearer picture, better defining mus sel control programs and alternate control methods. The uncertainty
caused by the often contradictory information now available, regar
ding exact treatment protocols and potential effect of the physical and chemical characteristics of the in
coming service water, underscores the fact that a sound biological moni toring effort is undoubtedly the most important component of any zebra mussel control program.
Also ofimportance is an external and internal inspection of intake structures and pipes which may be the first areas of the service water
system to feel the impact of zebra mussel infestation. Often a 48" pipe is drawing water through a crib with 6" slots; or an older pipe may already have structural damage or heavy sedimentation and become restricted by mussels within 6-8 months of infestation. These ins
pections help to define the time table for mussel control programs. Understanding the biology ofthe mussel is critical to understanding the best ways to control it. For example, attempting to control the zebra mussel once water tempera ture is below 12°C is an exercise in
futility. The mussel has such a low metabolic rate in cold water that it
does not have to filter chemically treated water for long periods of time. Treatment at cold tempera tures may take as long as 3-4 weeks, while taking only 3-4 days above 20°C, regardless of the amount of chemical used.
There are many aspects of the mussel's biology which can be mani pulated or taken advantage of to keep a system mussel free while reducing chemical costs and mini mizing environmental impact. As research continues for a chlo

Water Treatment
Upgrading the Waskatenau WTP
In the spring of1989,Associated
Engineering was asked by the Village of Waskatenau, Alberta to evaluate options to meet imme diate and future water supply and treatment needs. Its WTP, built in 1964, was assessed to have adequate capacity, but not the durability, to fulfill the Village's projected water demands.
"The 25 years of operation had taken their toll on the piping, pump, and electrical components which all exhibited signs of severe wear and corrosion,"says Associated Engine ering project manager Barry Vallance."The masonry walls and roo fing system were also in need of rehabilitation."
Faced with a choice of upgrading the existing plant or building a new one, the Council of the community 60 km northeast of Edmonton deci
ded to upgrade. Renovation began in January 1990 to upgrade the manuallyoperated facility to a semiautomated plant. Upgrading con sisted of replacement of all existing piping, fittings, valves and of all existing gravity filtration system components including the under-
drain. Existing electrical works were replaced with new electrical, control and instrumentation com
ponents to automate the backwash and sludge blow down operations.
The chemical feed system was re placed with new units. The existing aerator was retrofitted and a new
rapid mix system was installed. For a new look,the plant building was refaced with split-face block over new vapour barrier and insula

The upgraded facility began pro ducing potable water for the Village by the end of May. "A challenging part ofthe project was to provide residents with pota ble water during the construction period," says Barry Vallance. "The contractor, Nason Construction

Alberta's approach to meeting Canadian drinking water quality guidelines
The public's perception of, and confidence in, the safe-
ness of municipal drinking waters deteriorated signifi cantly in the 1980s as evidenced by the dramatic increase in the sales of
bottled water and point of use treat ment devices. It is the responsibility of federal, provincial and municipal governments, public health profes sionals as well as municipal consul tants to ensure that well co-ordinated
and integrated drinking water qua lity control programs are developed and implemented. Such programs should not only result in the produc tion of drinking water meeting the drinking water quality guidelines, but should also provide the safe guards and assurances that collec tively will convince an informed pub lic thattheir drinking water isindeed safe. Such a safe drinking water program can be sub-divided into five major elements. Figure 1 shows these five major elements, which taken collectively, and recognizing that there are overlaps and strong interrelationships between each ele ment, represent the type of compre hensive and effective regulatory pro gram necessary to ensure the provi sion of safe drinking water on a consistent basis.
In Alberta, responsibility for the regulation and control of municipal drinking water systems resides with Alberta Environment. The follow

Number and Types of Systems Water Supply and Treatment Systems In Alberta
Ensuring the adequacy of water supply and treatment systems from a design and process standpoint is considered a major element of any comprehensive safe drinking water program. Changes in technology, development of new and more strin gent drinking water quality guide lines, or just a better understanding of the limitation of certain techno
logies can be expected to result in continued changes to what consti tutes an "adequate" water system.
The proper operation and maintenance of
water supply and treatment systems Is an essential part of any effort...
Every effort must be made to ensure that existing water supply and treat ment systems are as "adequate" as possible based on today's guidelines /standards while also considering possible future changes in guide lines/standards.
The following activities are under taken in Alberta to achieve this
Application of Drinking Water Quality Guidelines The Guidelines for Canadian
Drinking Water Quality are notlegal ly enforceable standards unless adopted as such by the appropriate provincial, territorial or federal agency. In Alberta, the guidelines have been adopted, through the Alberta Clean Water Act legislation as the quality standards applying to municipal water supplies. For this reason. Alberta has a strong inter est in ensuring that the Guidelines are practical and implementable and 42

any permanent works. •issuance of Licence to Operate for the water supply and distribution systems.
In general, new requirements or standards are applied to a specific facility as part of an already plan
In Alberta
The number and type of munici pal waterworks systems in a given jurisdiction will partly determine the significance and impact of any changes in drinking water quality guideline limits or treatmentrequire ments.
In 1989 there were 271 munici
pally owned water supply systems in Alberta serving cities, towns, vil lages, summer villages and ham lets. Another 33 municipalities in the province were served by regional water supply systems or received waterfrom another municipality.In addition,there were in excess of400 non-municipally owned water sys tems serving developments such as schools, metis settlements, mobile home parks,provincial parks,water co-ops, commercial/industrial esta blishments,etc. Approximately twothirds of the municipalities utilize surface water as a supply source and these surface water supply systems serve over 1.8 million people. In general, groundwater is used as a water supply source in smaller muni cipalities and non-municipal deve lopments and serves approximately 300,000 people. The remainder of the 300,000 people in the province are served by private water supply systems such as wells,cisterns receiv ing trucked water, or dugouts. Supply and Treatment System Operation The proper operation and main tenance of water supply and treat ment systems is an essential part of any effort to ensure the on-going sustained production and delivery of the best quality drinking water that can possibly be produced. Eval uations ofperformance ofwater treat
ment plantsindicates that good oper ator training results in improved drinking water quality. Cost sum mary data on drinking water treat ment technologies also indicates that annual operating costs can rep resent a significant portion of the

total annualized cost, i.e. capital and operating costs, of treating drinking water. It is, therefore, important that regulatory agencies have programs and activities that promote, encourage, and to some extent, ensure the good operation
and maintenance of water supply systems.
In Alberta, the following activi ties related to the operation and maintenance of water supply sys tems are undertaken by Alberta Environment:

a specific concern/problem (e.g. two lead monitoring programs were re cently undertaken — one involving private residences and the other in volving schools). One of the issues created by com prehensive and ever-expanding drink ing water quality guidelines is the frequency at which drinking waters should be sampled and which para meters should be analyzed to deter mine compliance with the guide lines. In Alberta, compliance moni toring requirements for municipal water supply systems are partially established by legislation. Chemical quality must be moni tored at least once per year for well
To augment the province's basic compliance monitoring program, a comprehensive drinking water qua lity monitoring program entitled "Drinking Water Survey" was ini tiated in 1978. This monitoring pro gram analyzes over50 Alberta drink ing waters for an extensive number and type of substances and is simi lar in concept to Ontario's Drinking Water Surveillance Program. The purpose of this monitoring program is to evaluate the"quality" ofAlberta drinking waters in relation to guide line limits and also to obtain base line data which can be used to assess
long term trends or changes in drin king water quality.

Establishing reasonable and appropriate monitoring require ments for water supply facilities is perhaps one of the most difficult tasks ofa regulatory agency.Alberta Environment considers monitoring to fall into one ofthe following gene ral categories: (1) operational monitoring conduc ted by municipalities to control/ monitor the performance of water treatment processes;
(2) compliance monitoring conduc ted by municipalities to determine compliance with regulatory quality standards/guidelines; (3) compliance monitoring conduc ted by regulatory agencies such as

All sampling associated with the Drinking Water Survey is conducted by Alberta Envi ronment and all samples are analy zed by the Department's Alberta Environmental Centre Laboratory. Based on the results from the
Drinking Water Survey and other monitoring programs, drinking water quality throughout the pro vince is considered very good. Very few organic compounds have been detected in Alberta drinking waters with the exception of trihalomethanes.

Health and Safety Plans for Environmental Projects
Environmental consultants
or corporate in-house staff anticipating an environ mental project for industry in Canada are wise to include an expli cit Project Health and Safety Plan in their initial proposals and work plans. Such a Plan recognizes moral and legal responsibilities of the employer, and his contract employers, to protect their workers from hazardous exposures and plans for appropriate liability man agement during the project.

(1) what type of manufacturing pro cesses and storage occur at the site now and occurred in the past; (2) what is the environmental and health and safety compliance his tory of the site; (3) who are the neighboring waste generators; and (4) what is known of the geology, water table and prevailing weather,
include: •Identification of contaminants in
environmental media (e.g., soil, groundwater, air). •Measurement of contaminant con centrations in these media.
•Estimates of boundaries of sprea ding plumes, rates of spread. •Evaluation of leakage from under ground tanks,leaching from dumps. • Bioaccumulation, bioconcentra-
tion in plants and animals. •Remediation activities, e.g., opera ting purge wells, excavation. Depending on the contaminants, the media and the type of environ mental project, such activities may expose workers to potentially hazar dous materials. Most of the hazar dous materials encountered are not
covered by WHMIS, so there is no material safety data sheet to inform workers of health hazards and pre cautions to take.
The person preparing the propo sal or work plan for an environmen tal project may already know what
the site hazards are. If so, this sim plifies preparation of the Project 46
Project Health & Safety Plan. Design this Plan directly into the initial project proposal or work plan. State what are the anticipated or likely toxic contaminants, health effects from overexposure,appropri ate precautions(work practices, per sonal hygiene practices and facili ties,respirators and other protective gear), and emergency equipment to be provided (e.g., vehicular tele phone, portable eyewash, first aid supplies, fire extinguishers). In all cases the precautions have to be sca led to the anticipated degree of
which could influence contaminant
spread. Second, obtain a visual picture, past and present, by obtaining site plans and, if possible, visit the site. If available, regional maps and aerial photographs can be useful. During the first site visit, if authori zation and budget allow, take a few key environmental samples for ana lysis. These may be very helpful in customizing the proposal or work plan, and its health and safety com ponent, to match the problems of that site.
Third,phase the proposal or work plan into (1) a preliminary investi gation as the subsurface or its biota are first probed,(2)followed by focussed, more detailed testing to charac terize the contaminants of major concern and their spread, (3) then remedial operations. Now you are ready to design the
the project. Make sure that sufficient budget is estimated to cover anticipated costs. Itiseasierto justify an itemi zed budget. Insert a qualifier that if unexpected hazards are encounte red for which precautions are not in place, the work must be stopped,an expert consulted for proper precau tions and the Plan and its budget corrected, so it is safe to proceed. The Project Health and Safety Plan must clearly define the chain of command, both during routine operation and in emergencies, and this information must be included in
worker training. It is important to distinguish who will serve as the health and safety expert for the pro ject. In addition, it is important to provide for one or more site health and safety officers. Someone fulfil ling the role ofsite health and safety officer must be on site at all times
during field environmental opera tions. State clearly who has autho rity to stop work and to allow resump tion of work, on grounds of health and safety. An important part of the plan is air monitoring during site opera tions, to estimate hazards to wor
kers and the nearby public. Most environmental projects last firom a few days to a few weeks, but some involve on-going field work for many months. The usual air sam pling methods ofindustrial hygiene can be used when a potential expo sure is to continue for many months and the possible chemical toxic effects are from long-term,low level exposures.

The Hagersville Tire Fire Investigation
The Hagersville fire created
thick clouds of smoke, oily
and other contaminant streams and waste resi
dues. Fire fighting operations also added several thousand cubic
metres of wastewater runoff. People living up to 3 kilometres of the fire were evacuated from the surroun
ding rural and agricultural area. It has been called the worst tire fire in
Canada,consuming more than 13.9 million tires in 17 days,in February 1990. Monenco Consultants Limited
was retained by the Ontario Ministry of the Environment (MOE) in late March 1990, to conduct environ mentalimpactinvestigations and to design a remedial action plan for the site. Additional tasks consisted of
interim site and project manage ment,including delineation and re covery of subsurface oils. The work was completed in a record-breaking 10 weeks. This included: hydrogeological sampling, air quality moni toring, public consultation, and recommendation of site cleanup cri teria. Gore & Storrie Limited, under subcontract to Monenco, evaluated waste management and wastewater treatment issues and interviewed local residents.
Monenco's site investigation was focused on the actual burn area. Several shallow (air rotary) holes were drilled across the limestone
terrain and chemical testing was undertaken on the shallow soils and solid waste residues which remai ned after the fire. Extensive use was
made oflaptop computers at the job site for data collection and report generation in order to meet the demanding study schedule. Subsur face monitoring results, such as water table configuration and oil distribution were tabulated, plotted onto base maps, and interpreted by staff within 24 hours of collection.
The wide range of contaminants present in air, surface water and groundwater,soil, and wastes at the site required one of the most com prehensive reviews of cleanup crite ria ever undertaken in Canada. For
example, 43 organic and inorganic criteria for three different end land
uses were developed by Monenco for soils, using a proprietary computer risk assessment model called
"AERIS" (Aid for Evaluating the Redevelopment of Industrial Sites), which was developed in 1989 jointly by Monenco and Senes Consultants. Soils and other solid wastes were
then classified by Gore & Storrie by leachate toxicity testing. Surveys by Monenco and Gore & Storrie showed that the key public issues consisted of contaminant
levels and cleanup plans, health and safety, government manage ment ofthe crisis, compensation for affected residents, and community image indirectly tainted by intense media scrutiny of the environmen tal tragedy. There was a clear prefe
rence within the community,articu lated by the Public Liaison Commit tee,to undertake a local cleanup and avoid shipping the remaining pollu tion to other jurisdictions. Under existing procedures, assessment of and payment for compensation claims may take several months. To date, the largest costs arising from the fire have been associated
with management of the contami nated water. During the fire, 2,700 cubic metres were trucked to Missis-
sauga for emergency storage. This water was later returned when the
City of Mississauga refused to treat it. Portable on-site wastewater treat
ment facilities were erected by OHM of Canada under the supervision of Trow, Dames & Moore in early March 1990. Initial treatment para meters consisted of mono and polycyclic aromatics, phenolics, and metals. Approximately 7,500 cubic metres of water were treated and
released to Sandusk Creek on a spo radic basis before being discontin ued. Subsequent detailed analyses and criteria development identified additional parameters of concern such as ammonia, benzo(a)pyrene, and N-nitrosodimethylamine. Wastewater (19,500 cubic metres as of May 1990) presently is being stored in unused sewage lagoons in the nearby village ofTownsend.The

public would prefer on-site treat ment and subsequent release to Nanticoke Creek, in comparison with other options such as haulage to commercial treatment and disposal facilities or lagoon treatment. The cost of commercial transportable facilities for 12 months was estima
ted at $7 to $8 million. A fixed faci lity with reduced but adequate capa city, however, would cost less than half as much.
Monenco's extensive preliminary testing indicated that the area re quiring cleanup was restricted lar gely to the burn area. Solid wastes consist of approximately 20,000 cubic metres or 38,000 tonnes of tire residue, unburned tires, and conta minated soils exceeding MOE's draft soil cleanup guidelines for zinc, benzene, and henzo(a)pyrene. In addition, 12,000 to 50,000 litres of oil may be floating on the water table in portions of the same area. The solid wastes require treat ment or disposal, but are not consi dered to he hazardous wastes. Recy cling opportunities appear to be limi ted because of the extreme hetero
geneous nature of the wastes and the presence of chemical contami nants. Based on available informa
tion, two remedial concepts were recommended by Monenco. One involved excavation and disposal of waste in regional landfills. The other involved construction of a
trench-and-cap vault in the burn area. Capital costs for both con cepts have been estimated at about $10 million.
The total cost for extinguishing the fire and controlling the site was estimated by the MOE at approxi mately $30 million. Five youths have been charged with arson in connection with the incident. ES&E 49

High-tech systems provide potable water to Canadian forces In the Persian Gulf Zenon to the Department of Natio nal Defence(DND). The Advanced Double Pass Reverse Osmosis Water
Purification Units(ADROWPU)are used by the Army and the Ship board Reverse Osmosis Desalina
tion(SROD)units are on board the Canadian naval vessels. It was not until WWI that armed
forces were known to have provided water purification equipment in the battlefield. These early systems used simple sand filtration followed by chlorination. In WWII, water puri fication techniques varied with the theatre of operation. In Europe, where there was an abundance of
fresh(albeit polluted)water,conven tional treatment techniques such as batch coagulation, diatomite filters and chlorination were used. In the
Water borne disease has caused more deaths than all the wars of recorded
history. In past wars, more soldiers have lost their lives by disease than by armed combat.Dur ing the American Civil War, for example, disease related deaths greatly outnumbered battle casual ties. John Adams of the Continen
tal Congress once wrote "disease has destroyed ten of us where the sword of the enemy has killed one." Statistics for the major conflicts of this century show that the average number of hospital admissions for disease were three times more than
those due to enemy action. The greatest single cause of battlefield disease has been found to be conta minated water.
The supply of high quality pota ble water is therefore a fundamental
priority for any military action. Ground troops need water for drink ing, food preparation, laundry and personal hygiene. Navalforces have the same needs for their shipboard crews with the additional require ment for clean water for the produc tion of steam for the ship's turbines or for the cooling of diesel powered engines. Given the many con straints and hazards of military operations,meeting these water sup ply needs is a challenge. As recent events in the Middle East illustrate, this challenge can be much more difficult when there is a threat of
Nuclear, Biological or Chemical Warfare(NBCW)agents. Not only
Pacific theatre, where fresh water was scarce, distillation of seawater was necessary.
must a military water supply sys tem be capable of removing these NBCW contaminants from the raw
water source, but it also must be able to accommodate increased demand
since large quantities of water are used in the decontamination ofequip ment and personnel that have been exposed to this type of attack. Fortunately,the Canadian Forces are thought to have the most advan ced water purification systems avai lable anywhere. These systems are currently in use in the Persian Gulf supplying clean water for both the CF-18 Fighter operations and the Canadian naval vessels. At press time,additional equipment has been delivered and is enroute to provide water for the Canadian Field Hospi tal being deployed to Saudi Arabia. These military products use state-ofthe-art Reverse Osmosis (RO) sys tems technology developed in Canada and are manufactured by Zenon Water Systems Inc., Burling ton, Ontario. Reverse Osmosis is a pressure driven membrane separation tech nology. Membranes are used to solve a wide range ofenvironmental problemsfrom the treatment ofindus trial wastewater to the production of ultrapure water. This technology is ideal for military water supply sys tems since it is energy efficient,com pact, inherently rugged and, when properly designed into an integra ted system, is easy to operate and maintain. There are currently two different systems being provided by
Environmental Science & Engineering, March 1991
Today, the Canadian Forces ful fill a number of roles which include
commitments to NATO, United Nations peacekeeping and emer gency response. These commitments mean that they must plan for opera tions anywhere in the world and must have sufficient water purifica tion equipmentto support these ope rations. This equipment must pro vide high quality water under a variety of climatic and operational extremes. For example, in desert areas a soldier requires a minimum of 15 to 25 litres/ day and planners typically estimate needs of60 litres/ day per person on average. The raw water source may be "fresh", brack ish or seawater. In addition to the
threat of NBCW contaminants, the raw water may be highly polluted, turbid, coloured or have extremes in pH. The ADROWPU developed by Zenon for the Canadian Forces is
designed specifically to meet these requirements. The unit is totally self-contained and is designed to fit an International Standards Orga nization (ISO)container for ease of transportation. Itis fully-integrated with a feed pump, pretreatment fil ters, spiral wound RO membranes, and post chlorination. The ADROWPU is self-powered by an integral diesel generator and can be easily configured in-situ for single pass or double pass operation depend'ZENON Water Systems Inc. 55

With the demonstrated success of
reverse osmosis desalination sys tems for land installations, came a growing interest in the use of this technology for the shipboard supply of potable and boiler feed water. This technology was pioneered in Canada by Zenon with its Seagold line of SHOD systems for marine and coastguard shipping. DND first became interested in the technology due to its many operational benefits over conventional evaporation sys tems. The primary benefit is an estimated 50% decrease in operation al costs due to an overall reduction

In the past, this obviously limited the range and scope ofnaval operations since ships were constrained by the availability offresh water atfriendly ports. With the introduction ofsteam propulsion came the use of thermally driven desalination techniques such as flash evaporation or distillation. Although these techniques have been perfected and made more effi cient over the years,thermal energy is required, scaling from salt conti nues to be a problem and operating costs are considered to be high.

Detect problem bacteria or algae with easy-to-use BARTs The Biological Activity and Reac tion Tests(BART'^) provide a con venient way to detect the presence of bacteria or algae before excessive growth plugs and corrodes pipes and damages expensive equipment. BARTs are completely self-contain ed, and require no costly instru ments or apparatus, so they can be used in the laboratory or on-site. BARTs are easy to use, even for those with no testing experience. Simply fill the BART tube with water sample,incubate at room tem perature and compare observed reac tions to a reaction comparator chart

and impartial manner. Since the continuous proper oper ation of a water supply system is an essential aspect of providing safe drinking water, it is important that there be a strong and co-operative link between the regulatory agency and municipalities with respect to facility operation and maintenance. The above abatement activities are
considered to forge such a link. For example, the inspection activities result in regular and direct contact between the regulator and the muni cipality and results in the establish ment of specific operational related contacts. To be effective, this con tact should be seen by the municipa lity as beneficial. In this regard, abatement staff are environmental
engineers and technologists who, through their training and field acti vities, develop considerable exper tise in the operation of water supply systems and can provide helpful and useful advice to facility opera tors. ES&E

Collecting flow proportional samples has never been easier. SIGMA's new Streamlineâ&#x201E;˘ subcompact and standard sized samplers are flowmeters too: generate reports via hand-held interrogator Until now, monitoring flow and collecting flow proportional samples required two units â&#x20AC;&#x201D; a sampler and a flowmeter. Not any more. Streamline puts the flowmeter inside its new subcompact sampler: an easy-to-carry unit with room to spare in tight manholes. And only Streamline can handle the full range of sampling applications. One controller fits a subcompact and a standard sized base with nine composite and multiple bottle choices.
The new Streamline stores the time and date samples are taken, plus daily flow minimums, maximums and averages; total flow, cumulative average, cumulative total and flow chart. The RS232D serial interface allows data transfer to a laptop or hand-held interrogator. The interrogator can hold data from up to 9 samplers and interfaces with any IBM compatible PC or dot matrix printer for sampling/flow reports. Streamline's Delta C Liquid Sensing System is self-adjusting and nonfouling, eliminating sample volume calibration and guaranteeing repeatability independent of varying heads at the intake. Streamline starts watertight; stays watertight: electro mechanical components are sealed in a NEMA 4X 6 housing and both keypad and display are protected by a waterproof polyester membrane.
