on rights-based population policies, pol-icymakers can ethically and effectivelyaddress population-related challengesby empowering women to make theirreproductive choices.

If most or all of these strategieswere put into effect, Engelman feelsthat global population might begin agradual decline before 2050. If thishappens, humanity’s undeniable re-sourcefulness should be able to achievesustainable development of natural re-sources, environmental protection, andhealth and prosperity for all.

If we are not able to control ournumbers, then ultimately nature will doit for us, but likely in ways too hideousand painful to consider. Europe’s his-torical plagues and, more recently, the1918 flu epidemic killed tens of mil-lions in a relatively short time span.These pandemics were all largely dueto overpopulation and a populaceweakened by war and malnutrition. Anincreasingly crowded world is onceagain facing these same issues.

4. Offer age-appropriate sexualityeducation for all students.

5. End all policies that reward par-ents financially based on the number ofchildren they have. Governments canpreserve and even increase tax andother financial benefits aimed at help-ing parents by linking these not to thenumber of children they have, but toparenthood status itself.

6. Integrate lessons on population,environment, and development intoschool curricula at multiple levels. Re-fraining from advocacy or propaganda,schools should educate students tomake well-informed choices about theimpacts of their behavior, includingchildbearing, on the environment.

7. Put prices on environmental costsand impacts. In quantifying the cost ofan additional family member by calcu-lating taxes and increased food costs,couples may decide that the price ofhaving an additional child is too high.

8. Adjust to an aging population in-stead of boosting childbearing throughgovernment incentives and programs.Population aging must be met with theneeded societal adjustments, such asincreased labor participation, ratherthan by offering incentives to women tohave more children.

9. Convince leaders to commit tostabilizing population growth throughthe exercise of human rights and humandevelopment. By educating themselves

Comment by Steve Davey

Recently, I was asked by friendsif I thought climate changeand global warming were themost important environmen-

tal issues humanity faced. They weresomewhat surprised when I said, no. Inmy opinion, overpopulation is the mainproblem we face as it is the root cause ofso many other issues.

Here are the facts. At the beginningof the 19th century, human populationis thought to have been about one bil-lion. By 1927, it had doubled, and by1960 it had reached three billion. Ac-cording to a United Nations report, theworld’s population reached seven bil-lion in October 2011.

According to some forecasts it willreach eight billion by 2030, and aroundnine billion by 2050. Incredibly, if the2010 global fertility rate of 2.52 birthsper woman continues, there are predic-tions that the human population couldreach 24.8 billion by 2150.

However, there is some hope that thisunsustainable growth can be avoided. Inhis new book State of the World 2012:Moving Toward Sustainable Prosperity,Worldwatch Institute President RobertEngelman outlines a series of steps andinitiatives that would lower birthratesand halt future population growth.

The book outlines nine strategiesthat could put human population on anenvironmentally sustainable path:

1. Provide universal access to safeand effective contraceptive options forboth sexes.

2. Guarantee education through sec-ondary school for all, especially girls.In every culture surveyed to date,women who have completed at leastsome secondary school have fewerchildren on average, and have childrenlater in life, than do women who haveless education.

3. Eradicate gender bias from law,economic opportunity, health, and cul-ture. Women who can own, inherit, andmanage property, divorce, obtain credit,and participate in civic and political af-fairs on equal terms with men, are morelikely to postpone childbearing and tohave fewer children compared to womenwho are deprived of these rights.

Seven billion and counting!

24.8 billion of us by 2150?

Human Resources

For another, the study provides an op-portunity to compare the differences inperspective between environmental pro-fessionals and employers. Earlier this year,ECO Canada completed a landmark re-port to determine environmental employ-ees’ level of engagement and expectationson preferred human resource strategies.To complement this research, the most re-cent study flips the focus around to envi-ronmental employers, and collects theirfeedback on the most essential employeecompetencies and HR practices requiredby their own organizations.

Much of the success of environmen-tal organizations depends on the spe-cialized skills and expertise of thepeople performing the work, making itessential for employers to be able to findand keep the right professionals. ECOCanada’s report helps environmentalemployers discover which employee re-cruitment and retention practices workwell, identify the most pressing HR chal-lenges that their industry faces, andlearn about effective new approaches. Ithas yielded a number of important andunanticipated findings.

What it takes to land a job, keep it and advance

During an initial phase of the study,environmental employers were pre-sented with this fundamental question:What does it take for environmental pro-fessionals to get a job? In their re-sponses, employers consistently referredto three major categories of employeecompetencies and attributes:

1. It was important for a potential em-ployee to possess “hard” competencies,including a relevant post-secondary de-gree or diploma, professional certifica-tions, long-term industry experience andstrong technical or scientific skills asso-ciated with certain disciplines.

2. Employers also strongly valuedspecific soft competencies, includinggood communication skills (especiallywriting), critical thinking, customerservice skills, business savvy, researchskills and technological capability.

3. Lastly, employers noted which per-sonality attributes they liked to see in a

Environmental industries aregrowing, environmental em-ployment is growing, and bothof these trends show no signs

of stopping in the near future. What isless well known is the speed at whichthis growth is happening.

Within a relatively short time, ECO(Environmental Careers Organization)Canada has observed a dramatic in-crease in environmental employment. In2007, the Profile of Canadian Environ-mental Employment study found thatmore than 105,220 Canadian businesseshired environmental employees, with atotal of 530,414 professionals perform-ing environmental work. By 2010, over318,000 organizations in Canada had en-vironmental workers on staff, and morethan 682,000 employees spent at least50% of their time on environmental ac-tivities.

Yet, while there is growing evidencefor the accelerating growth of environ-mental work, there continues to be onlylimited information available on thespecifics of environmental employment.Clearly, working in the environmentpresents an appealing and viable careerpath for numerous potential workers.But, what does it actually take to getone’s foot in the door? Moreover, howcan employees ensure their continuedcareer success at an organization oncethey have been hired?

These questions formed the basis ofECO Canada’s latest study on environ-mental employers, with an overall goalof providing the best possible insightinto what it takes to get a job, keep thejob, and get promoted.

Over the course of the study, it wasapparent that there would be a numberof important implications. For one, thestudy results have helped uncover anddebunk several popular misconceptionsabout environmental work. These in-clude the assumption that technical ex-pertise is more integral to environmentalwork than soft competencies, as well asthe belief that a passion for the environ-ment is a necessary and expected trait inemployees.

job candidate. They had a clear prefer-ence for workers who were goal-ori-ented, autonomous, capable of workingwell under stress, and team players, witha clearly evident “can do” attitude.

While these competencies and attrib-utes in general may not be surprising,their order of importance to environ-mental employers is. Intuition wouldsuggest that hard competencies, such astechnical or scientific expertise, wouldbe the most valuable to employers, sinceenvironmental industries are typicallycharacterized by rapid technologicalchanges and complicated regulatory re-quirements.

However, many employers in thestudy placed a higher degree of impor-tance on soft competencies and person-ality attributes. In their view, employeescan easily attain the necessary technicalskills, but a true talent for communicat-ing, client service and even businesssense is much more innate and therebyconsiderably harder to train for.

Not only did environmental employ-ers stress the importance of soft compe-tencies and personality, they also notedwhich sub-areas appeared to be in ex-ceptionally short supply. According tothese employers, there is a noticeablelack of adequate communication andbusiness ability in many employees.Communication, from grammar and

writing, to the ability to conduct criticalanalysis and write technical reports, wasan especially important concern forthem. This competency is essential be-cause employees working in environ-mental businesses often need to explainhighly technical processes to clients inlaymen’s terms.

In summary, the study arrived at akey message for environmental practi-tioners looking to maximize their careergrowth. In order to get a job, keep a joband thrive in the environmental sector, itis crucial for professionals to:• Be original thinkers.• Bring a “can-do” attitude to the job.• Be effective problem-solvers.• Demonstrate common sense.• Be curious and tenacious.• Love what they do.

Expanding on the last point about en-joying one’s work, environmental em-ployers provided a key observation. Thepreference for employees who clearlytook pleasure in their job was not quitethe same as a preference for workerswho demonstrated a passion for the en-vironment or environmental issues. Infact, employers placed a higher value ontheir staff’s ability to maintain objectiv-ity in their work. This is due to the needfor many environmental consultingfirms to provide independent and bal-anced assessments for their clients.

The business benefits of being an employer of choice

In addition to outlining which em-ployee competencies and attributes werethe most essential, environmental em-ployers also discussed the strategies thatthey used to retain existing employeesand become employers of choice. Formany, well-developed HR strategieswere not simply a “nice to have” or anextraneous cost to the organization. In-stead, such policies were seen as valuableinvestments directly linked to the overallsuccess of their company.

An informed and effective plan for be-coming an employer of choice helpedthese employers to attract desirable can-didates when hiring, as well as to driveengagement, retention and productivityamong their current employees. More-over, these strategies went well beyondsimply providing good salaries or bene-fits. In the experience of these employ-ers, much more was actually needed to

With the emergence of new industries and the continued expansion of traditional environmental activities, environmental employers are increasinglyhard-pressed to find and keep skilled practitioners.

engender long-term loyalty and retention. Accordingly, environmental employ-

ers described four different platformsthat they based their “employer ofchoice” practices upon:

1. Environmental leaders. In thisapproach, employers invest money andtime in their involvement as speakers,advocates and spokespeople for relevantenvironmental, professional or scientificorganizations. They strive to establishbrand-name recognition and credibilityas experts in their field for potentialclients and future employees. To meetthese objectives, employers who use thisapproach seek out professionals who arelikely to bring passion and commitmentto their work.

2. Remuneration. Here, companiesfocus on remuneration, making an effortto provide the best benefits, top or near-top pay, and matching RRSP contribu-tions. To complement this strategy,employers frequently emphasize howtheir organization also features integrity,a sense of meaning and accomplishmentin one’s work, and the feeling of beingvalued by the employer. More often thannot, this approach appeals to employerswhen they need to fill seasonal posi-tions, or when their work takes place inresource industries with less desirablework locations.

3. Flexible and like a family. Foremployers who understand the impor-tance of a changing work dynamic, thisstrategy caters to the flexible lifestyle

needs of all levels of employees. Com-panies rely on this platform to create afamilial atmosphere in their organiza-tion, with a strong emphasis on how theyprovide a safe, caring and positive placeto work. This approach works particu-larly well for smaller companies, al-though a growing number of largerbusinesses are also making an effort tobe more flexible and accommodatingwith their staff.

4. Launching pads. In this strategy,employers realize that they are not likelyto retain their employees for more thanfive years. As a result, these companiestry to provide as much training as possi-ble, along with a competitive salary andbenefits. At first glance, such an ap-proach would seem self-defeating. How-ever, there is one unexpected potentialbenefit for environmental consultants.Well-trained employees often leave tojoin companies that were previousclients. This could actually help the con-sulting firm’s client retention, sincesome of their clients now include formerwork colleagues.

Each of these four “employer ofchoice” strategies differs considerablyfrom the others, and as a result, eachpresents distinct advantages and disad-vantages to environmental employers. Toensure that they have developed the mosteffective approach possible, employersfrequently use a combination of all four,as opposed to focusing on just one.

Furthermore, environmental employ-ers in ECO Canada’s study also men-tioned a number of “insider” tips thathad worked well for them in their HRplanning. These strategies includedlooking at the engagement practices ofsuccessful companies, interviewing can-

didates that had actually turned down ajob offer, and listening to the feedbackof new hires.

Environmental employers can buildon these creative and effective HR tac-tics even further by adopting the engage-ment strategies that professionals prefer.

While employers believed that mentor-ship opportunities and the chance to trainfellow colleagues were effective ways toboost employee engagement, environ-mental professionals did not share thisperspective. For them, it was more im-portant that their employers supportedongoing professional development, pro-vided training in environmental or tech-nical topics, and hosted company eventsto highlight achievements.

For professionals, finding and keepinga job, and advancing in one’s career is notalways easy in an industry characterizedby rapid change and increasing skill re-quirements. Similarly, environmental em-ployers face significant challenges both infinding the right professionals to supporttheir business activities, and in keepingthis talent once they have found it. Forboth sides of the equation, ECO Canada’slatest study provides an important sourceof new information to ensure sustainablelabour growth in environmental industries.

For many environmental employers, soft competencies and personality attributes are paramount. In the view of these employers, professionals caneasily attain the necessary technical skills, but a true talent for communication,client service and business sense is much harder to come by.

duced or zero cost. Typically, workshoptopics are broad enough to provide anoverview and good understanding of afield, while detailed enough to allow par-ticipants to apply the information to theirwork. They are technical in nature and in-clude presentations by topic-specific ex-perts, speaking about relevant theory andcase studies.

Social events include mixers, holidayparties, sports and charity events. Again,these events are usually free of charge. Al-though at first glance it seems that a so-cial event is just that, it does offerparticipants a chance to improve their net-working and social skills, while meetingnew people and catching up with oldfriends. These skills are integral to manyprofessional roles, including sales andconsulting, but can be challenging tolearn. YP events offer a casual environ-ment for young people to interact withtheir peers in the industry.

Site tours and visits are another keyarea where YP committees provide an en-joyable way to learn about the industry.They can include visits to places like waterand wastewater treatment facilities, equip-

Young professionals can be de-fined as people in the envi-ronmental industry who areunder 35 years old, with less

than five or 10 years of industry experi-ence. Exact requirements will vary de-pending on the organization.

Many professional organizations in theenvironmental field offer young profes-sional (YP) committees that enable youngpeople to participate with others with sim-ilar work backgrounds, either by attend-ing events or even participating inplanning. For example:• American Water Works Association

(AWWA) National YP Committee• AWWA Sections YP Committees, e.g.,

Ontario Water Works Association YP Committee

• Water Environment Federation (WEF) Students and Young Professionals Committee

• WEF Section Committees, e.g., Water Environment Association of Ontario (WEAO) New Professionals (NP) CommitteeYPs include individuals in any line of

work, such as consulting, manufacturing,operations, equipment sales, contractingand more. Generally, their committeeshold seminars and workshops, socialevents and site tours. Many, if not all,events are not restricted to just YPs. In-deed, seasoned professionals are morethan welcome to attend, and encouragedto do so.

What is the value of participation?Young people who participate in events

associated with professional associationsgain hands-on experience and invaluableskills that sometimes cannot be learned onthe job or through coursework. Given thatevents are run by YPs and part of the tar-get audience is YPs, these events offer anon-intimidating environment for indi-viduals to move ahead in the industry anddevelop their skills outside the workplace.

Technical seminars and workshops or-ganized by YP committees are geared to-ward topics that interest young people andprovide an excellent means for profes-sional development, with the bonus of re-

ment manufacturing plants and powerplants. This provides a behind-the-sceneslook at facilities one rarely has the oppor-tunity to see.

Because YPs are new to their work,they have not yet had a chance to experi-ence the many processes and equipmentthat they work with. It is one thing to sizea pump in an office, but quite another tosee one running, or how it is built. Sitevisits provide YPs with context for theirwork and help with viewing the biggerpicture. They also offer an opportunity toask the guide, usually a senior operator ormanager at the facility, questions aboutthe process and equipment that may relateback to their projects or personal interest.Benefit to employers and the industry

In addition to all the personal benefitsto YPs, employers gain advantages fromencouraging their young (and seasoned)staff members to participate in YP events.

Many employers require personnel tocomplete a minimum amount of formalprofessional development annually in theform of conferences, seminars or courses.The costs can be a burden to professional

development budgets. Employers can takeadvantage of reduced rates for YPs andencourage their young staff to attend asmany free technical events as possible.This not only helps the company savemoney, but also shows employees that thefirm has an interest in their professionaldevelopment.

Similarly, firms are not always able toschedule site visits or tours due to logisti-cal constraints and conflicting schedules.YP committees tend to schedule site vis-its on weekends, understanding that week-day visits can be difficult to attend.Employers can use this as another inex-pensive (or free) opportunity for profes-sional development.

A key factor in adult learning is moti-vation, which can be in the form of socialrelationships, personal advancement orescape/stimulation. Site visits can provideeffective learning opportunities by satis-fying these motivators through providingnetworking opportunities, personal pro-fessional development and time awayfrom the office. They can be an inexpen-sive way to enhance learning among staff,allowing them to tie together work in the

office and the field. For even more benefit, younger staff

can be encouraged to participate in an or-ganizing committee. This provides a greatway to improve general and time man-

agement skills, as well as organization andcommunication abilities — all critical fora successful business. Moreover, word-of-mouth referrals and updates, or discus-sions about work, occur naturally amongYP committee members. They are an ef-fective way to market a product line orservice expertise.

Human Resources

YP committees help to bridge the gapand transition young people into theworkforce. Young professionals are the fu-ture of the industry, and success dependson them learning both the technical andsoft skills they need to move ahead.

How can you participate?Contact the local chapter of your pre-

ferred professional organization and askif they have a YP committee. If they do,contact the chair of the committee to getspecific information and join the mailinglist. If not, it would be worthwhile to findout why, and suggest that one be started.

The Internet is another great resource.Consider searching the terms “young pro-fessiona ls committee,” your city and theorganization of choice. Social media likeFacebook and Twitter can offer anotherangle at finding local committees andevents.

customer-owned portion of the plumbing,by detecting a constant flow of water.Such technology not only helps to con-serve water, but helps the customer avoidunnecessarily high water bills. 2. Continuous Acoustic Monitoring ofWater Mains via Valves. Leak detect-ing sensors that record sound vibrationsovernight are installed on water mainvalves or water services. Trained staffperiodically download the informationinto specially designed software to ana-lyze pipe noise for the sound of leaks. 3. GIS Analysis. Reviewing historicalleak information via GIS mapping helpsclearly identify leak-prone areas, whichtypically occur in smaller-diameter pipesinstalled more than 50 years ago. 4. Improved Pressure Control. Reduc-ing and modulating water pressure inwater systems lowers the amount ofwater leaking out of pipes and reducesstress on pipes, while still providing cus-tomers with needed supply. 5. Large Transmission Main Testing.Several complex methods are currentlybeing evaluated to detect leaks on largepipes, including inserting leak-findingsensors inside water pipes and sensingnoise transmitted by running water. 6. Leakage Control Zones. Some sys-tems are subdivided into separate “zonesof supply” monitored by master metersthat periodically measure water use in aparticular area. Higher-than-expectedwater flow in the middle of the night is atip-off that a certain spot requires furtherinvestigation. 7. Main Replacement Program. Watersystem data, especially main breaks, arecollected and evaluated to identify andreplace ageing mains.

Finding solutionsIn some cases, advanced metering in-

frastructure (AMI) and continuousacoustic monitoring (CAM) technolo-gies work to detect hard-to-find leaks ina timely manner and better managewater loss. AMI involves a two-waycommunication device that automati-cally collects and transmits consumptionand interval data from smart meters to a

Meeting current demand andsupplying water for futuregenerations are significantchallenges for the water

industry. Leak detection can signifi-cantly reduce consumption and ease thestrain on water supplies.

Deteriorating infrastructure, fluctuat-ing water temperatures, soil movement,vibrations and water pressure changesare just some of the factors contributingto water leakage. Not only do leaks ac-count for lost water, they can also allowcontaminants into the system that en-danger public health.

It is up to utilities and municipalitiesto adopt and implement technologies tomore effectively manage and conservewater supplies by developing methods todetect, locate and stop leaks. A leak de-tection program can be highly proactive,help water utilities automate water sys-tems, detect problem areas earlier, andprovide tools to monitor water use, pro-vide more accurate rates, and reduce de-mand.

Benefits of leak detectionIt is essential that this resource be cap-

tured, not only because it is becoming in-creasingly scarce but also because of theenergy used to produce it and its green-house gas footprint. Minimizing leakagehas many other benefits, including:• Extended life of pumping and

treatment facilities. • Improved operational efficiency. • Less disruption for business and

highways. • Lowered water system operational

costs. • Reduced potential for contamination. • Reduced potential property damage

and water system liability. • Reduced water outage events.

Technology in practiceWater industry experts have devel-

oped comprehensive water preservationand efficiency strategies, utilizing leakdetection technologies, including: 1. Automatic Meter Reading. Advancesin water meter technology can automati-cally record and report leakage within the

computer network. The utility then ana-lyzes this data to uncover irregularitiesthat likely signal a leak, meter tamper-ing or water theft.

By deploying these technologiesthroughout distribution systems, waterutilities are able to survey for pipelineleaks every day. The acoustic monitors,whether installed on the service line orplaced on valves in the distribution sys-tem, can relay data back through theAMI telemetry system to operatorsusing an analytic software package. Thesoftware processes data and alerts thesystem operator when a monitor is de-tecting a “noise” indicative of a leak.

Sophisticated vendor software dis-played via Web sites interprets changesand the magnitude of sounds to rankpossible source locations and to identifythe exact location of the leak. The leakcan then be repaired, or the infrastruc-ture replaced, as required. In the end,using these technologies to find leaksand better record water usage improvescustomer service, conserves water andkeeps rates down.

The effective use of technologies thatprotect water supplies and manage non-revenue loss also promotes the impor-tance of conservation among customers.Public awareness programs are crucialfor educating customers about how touse water more wisely. AMI data canserve as a communication tool for in-forming customers about their currentwater use patterns.

By detecting and repairing leaks, util-ities can save water and energy. House-holds and businesses can do their part byinstalling low-flow household faucetsand toilets, stormwater collection sys-tems, and timed or climate-controlled ir-rigation systems as a means of limitingwater usage. Becoming more informedabout water use habits will enable thepopulation to make better and more con-scious decisions about water use in thefuture.

Cover Story

Located in Toronto, SherbourneCommon is an innovative wa-terfront park that provides thepublic with green recreational

space along Lake Ontario in a former in-dustrial area.

This park features three large art sculp-tures that rise almost nine metres from theground. Known as “Light Showers”, thesesculptures combine water and lights tocreate a stunning visual piece. The waterthen flows through an artificial river ac-cessible to the public before discharge intoLake Ontario.

Environmental sustainability was animportant element in the design of the wa-terfront park. Water used in the art sculp-tures comes from either Lake Ontario, orfrom stormwater collected at the park.Stormwater runoff is stored in under-ground tanks that allow for sedimentationof suspended solids. Clarified runoff isthen sent for disinfection, before exitingthe water features.

Because the water features are accessi-ble to the public, water must be disinfec-ted in order to make it suitable for humancontact. Historically, a limit of 100CFU/100 mL of E.coli has been adoptedfor safe swimming in Lake Ontario. How-ever, the design limit for this project was10 CFU/100 mL of E.coli. This is espe-cially important because the area is sus-ceptible to combined sewer overflow(CSO) events during periods of intenserainfall which can increase the potentialfor microbial contamination in the park’swater supply.

In order to meet the disinfection crite-ria for this project, ultraviolet (UV) disin-fection was selected as the preferredprocess. With UV, no chemicals are used,which eliminates the formation of disin-fection by-products typically formedthrough chlorination. UV has the addedbenefit of inactivating chlorine-resistantprotozoa like Cryptosporidium and Giar-dia that are regulated to low limits. This isCanada’s first installation of UV for aneighborhood-wide stormwater treatmentsystem.

In the summer of 2011, Trojan Tech-nologies installed two TrojanUVFit™ re-

actors at the Sherbourne Commonstormwater treatment facility, located inthe basement of the park’s pavilion. Eachunit can operate at a flow rate of 70 L/s, al-lowing for 100% redundancy. Space hasbeen allocated for future expansion toallow installation of an additional reactorfor ultimate treatment of 140 L/s (with50% redundancy).

The TrojanUVFit is a closed-vesselsystem, available in multiple configura-tions to treat a wide range of flow rates.The streamlined hydraulic profile ofclosed-vessel systems disinfects effluentwithout head loss during the treatmentprocess. These benefits, along with UV’sability to provide chemical-free treatmentfor chlorine-resistant microorganisms,made this system an attractive option forthis application.

Each reactor features an automatic

wiping system to minimize quartz sleevefouling. This feature maximizes the UVoutput from the lamps and, along with au-tomatic dimming capabilities, reducesoverall power consumption.

Another key requirement for this proj-ect was the demonstrated performance ofthe UV system. The reactors have all un-dergone bioassay validation testing in ac-cordance with the Ultraviolet DisinfectionGuidelines for Drinking Water and WaterReuse (NWRI/AwwaRF, May 2003). This

third-party testing confirms the reactorsas sized to meet the project’s disinfectionlimits, and will perform consistently underreal-world conditions. They were vali-dated over a wide range of flow rates andUVTs. This allows for accurate and reli-able sizing based on empirical data whichis critical in reuse and stormwater appli-cations.

Instrumentation

missioning, two distinct programmablelogic controllers (PLCs) are installed onthe common Input/Output (I/O) set withineach control panel. The new PLC is thenconnected to its own SCADA interface,human machine interface (HMI) and/or athin-client SCADA node, depending onproject configurations.

Application loads are then developedfor each PLC and each respective sub-process by referring to the adjacentlegacy control. During the applicationdevelopment, the integration team lever-ages system integration advancements intechnologies and seeks to refine sub-processes. This is accomplished by re-ferring to the legacy control functionalityand utilizing the experience and famil-iarity of the operators.

Co-existence of legacy and new con-trol allows for a unique perspective fromplant operations. An operator and thesystems integration team can refer to thenew control interface side-by-side withthe legacy control system interface.Each system can be switched, seam-lessly, between control and supervisoryroles, and vice versa. Under PCS instal-lations, if an operator cannot easily findsomething within the new control inter-face, they can utilize the legacy systemas a fall-back option. Then, the integra-tion team can make adjustments during

Plant control systems consolidatethe physical assets of water andwastewater treatment facilities.When these systems go down,

the entire plant is affected. Preventativestrategies are impossible with integratedcontrol systems, as they rarely showwarning signs prior to failure.

As such, all municipalities should es-tablish a regimented replacement sched-ule for all integrated processor basedcontrol systems, based on a 15 - 20 yearlifecycle. The challenge with control sys-tems is that they completely engulf theprocess of every water or wastewater fa-cility and cannot be taken off line, with-out impacting process delivery, quality,and operations.

The key to upgrading legacy systemsis to provide an unwavering operationalacceptance, through a completely seam-less control transfer utilizing a ParallelControl System (PCS) approach. The dis-tinct feature of the PCS approach is theco-existence of both the legacy and thenew control system. This enables the in-tegration team to present a “real-time”side-by-side comparison of each controlsystem during the upgrade.

The installation process involves eachcontrol panel. The new control system istemporarily mounted beside the old con-troller. This is done so that during com-

the commissioning process.Once the systems are established, com-

missioning perspectives can shift towardsusing any technological advances. Thisprovides an opportunity to streamline ex-isting processes that may have been inap-propriately controlled through the legacycontrol system. These improvements canpositively impact plant efficiencies, re-duce chemical and power costs, while im-proving plant performance. Also, therewill be opportunities in advancements incommunications. For example, leveraginginternet communications through secureVirtual Private Network/Wide Area Net-work configurations makes data on allmunicipal infrastructure available any-where, and in real time, to central control,maintenance management and data ac-quisition systems.

The Parallel Control System ap-proach has proven that the ease and com-fort of being able to re-establish thelegacy systems during commissioning, iskey to establishing operator confidenceabout removing those systems, once thenew system is established.

Water Treatment

forming DBPs will be reduced, becauseless organic material will remain in thewater to react with chlorine. However,this process change eliminates the freechlorine residual from the filters andtherefore eliminates the ability to controlMn by IOCME.

In addition, without chlorine’s bio-logical suppression, the amount of bio-logical activity in the filter will increasesignificantly. Other treatment objectivesthat may cause a water utility to use bi-ologically active filtration (BAF) as partof its treatment process include stabi-lization of the water when ozone is used,removal of specific compounds such asammonia through nitrification, and re-moval of biodegradable contaminants inthe water.

If biological oxidation of Mn(II) canbe established in the filter bed, then Mncan be oxidized and retained in the filtereven in the absence of chlorine. Biologi-cal processes have been used in Europeand Canada for the control of manganese.

Research approachA Water Research Foundation project

on the subject consisted of the followingcomponents:

One of the most effective andcommon means of Man-ganese (Mn) removal inwater treatment plants is the

induced oxide-coated media effect(IOCME), which sequesters Mn on thefilter media in the presence of an oxidantsuch as chlorine.

IOCME controls Mn so transparentlythat some water utilities may not recog-nize that Mn is being removed. This is es-pecially true for utilities that do not havea significant Mn concentration in thesource water, but add Mn to the processthrough impurities in process chemicals,such as coagulants, or recycle flows.

The adsorption/oxidation mechanismassociated with Mn removal by IOCMEis well known. Oxidation of manganousMn [Mn(II)] by oxygen is a slow reac-tion at pH values below 9.5. Oxidationof Mn(II) by strong oxidants such aschlorine and permanganate are faster, al-though they are strongly dependent uponsolution conditions, such as pH and tem-perature.

If the application of a strong oxidantis terminated, filters can continue to re-move applied Mn(II) as long as Mnoxide adsorption sites are available.When these sites are exhausted, Mn re-moval will cease and the filters will passdissolved Mn directly to the filter efflu-ent. Moreover, the oxides of Mn can bereduced by organic material retained inthe filter bed or organic material in theinfluent water. This means that filter ef-fluent Mn concentrations can exceed in-fluent Mn concentrations.

Some utilities have experienced a sig-nificant release of accumulated Mn fromthe filter media, which decreases the aes-thetic quality of drinking water during thetransition period to a biological mode.

More stringent drinking water regula-tions for disinfection byproducts (DBP)have caused many water utilities to im-plement changes or consider implemen-tation of changes to move the initialapplication point for chlorine to down-stream of the filters. By moving the chlo-rine application further downstream inthe treatment process, the potential for

1. A literature search to expand uponprevious Water Research Foundationprojects to include literature relevant tothe understanding of the control of Mnby biological processes.

2. Surveys of several water utilitiesthat use BAF to gain a better under-standing of their Mn-control challenges,the treatment processes that they use attheir plants, and their operational expe-riences.

3. Collection and analysis of samplesfrom full-scale water treatment plants(WTP), a pilot plant, and a demonstra-tion plant to study and quantify a filter’sability to biologically remove Mn andthe relationship of metals coating on thefilter media to BAF.

4. Testing at a Philadelphia Water De-partment (PWD) pilot plant to deter-mine the impact of water quality andoperational factors on the ability ofgranular filter media to control Mn aftertermination of free chlorine from thewater applied to the filter.

minum-based). In addition, the initialoperation of filters in a biological modewas observed using the PWD pilot plantto mimic start up.

5. Testing with the Gold Coast Water(GCW) demonstration plant in Australiato determine the impact of several factorsthat may stress the effectiveness of BAFfor removing Mn. The factors investi-gated were elevated Mn loading, elevatedand reduced pH, and oxidation inhibitors(phosphate, nitrite, and ammonia). Alsostudied at the GCW demonstration plantwas the impact of sulfide contaminationon BAF.

6. Microbiological testing of thebiofilm from filters, which were oper-ated in a biologically active mode, tocharacterize the microbial communitiesin a general way.

Results/conclusionsThere are full-scale water treatment

plants that control Manganese using bi-ological aerated filter (BAF) technology.The biological filters at these plantshave a media with a well establishedMn-oxide coating. At one plant, the Mn-oxide coating appeared to have devel-

oped in the presence of both an abioticand a biotic process. At another plant,the Mn-oxide coating was the result ofbiological activity alone.

The investigations showed that themedia material had an effect on Mn re-moval. In a side-by-side comparison,Mn was removed significantly better bya granular activated carbon (GAC) filterthan by an anthracite filter. There wasmore Mn-oxide coating on the GACmedia than on the anthracite media.

Utilities that were unable to controlMn with BAF had little Mn-oxide coat-ing on the filter media. Pilot plant re-search was conducted to determine whatwould happen once chlorine was termi-nated. As expected, the filters were ableto control Mn for a period of time untilthe adsorption sites were filled. Whenthe sites were full, the media began torelease Mn.

The duration of the transition period(from chlorine termination to Mn re-lease) was shown to be generally a func-tion of pH and water temperature. Thehigher the pH, the longer the filter wasable to control Mn. Similarly, the

warmer the water, the longer the filtercontrolled Mn. It was also shown thatthe greater the Mn-oxide coating, thegreater the amount of Mn released to thefilter effluent and the longer it took toreach a new steady state condition.

An attempt was made to run the pilotplant filters continuously in a biologicalmode to promote the development of aMn-oxidizing biofilm. However, thebiofilm could not be established duringthe six-week duration of the investiga-tion. Previous research has indicatedthat the seeding of a filter is required,but often it occurs naturally from bacte-ria in the source water.

The principal investigators (PI) con-cluded that Mn-oxidizing bacteria mustnot have been present in the influentwater. If the bacteria were present, thePIs believe that the filter would have es-tablished a Mn-oxidizing biofilm withinsix weeks. Future research could test theefficacy of introduction of known Mn-oxidizing bacteria into a filter (seedingthe reactor).

developed at one site and then moved toanother.

The filter retained its ability to con-trol Mn. However, after an episode oc-curred that destroyed the biofilm, thefilter was unable to re-establish the mi-crobial population needed to controlMn. This was because the Mn-oxidizingbacteria were not present in the newsource water.

Gold Coast Water in Australia testedthe robustness of a biologically activeupflow filter using a demonstrationplant. The filter was stressed with highMn loads, phosphate, nitrite, and am-monia. It reflected the anticipated in-hibitory effects of these stressors byreduced Mn-removal performance, butwas still able to remove Mn. Only in thecase of sulfide, a true biofilm toxin, didthe filter’s biofilm lose its Mn-removalcapacity. Even in that case, the biofilmrecovered in 1 to 2 weeks. The demon-stration plant investigations also deter-mined that pH had an impact on Mnremoval. Of three test pHs, a pH of 7.9provided the best performance and a pHof 5.2 provided the worst.

Terminal restriction fragment lengthpolymorphism (T-RFLP) analyses of thebiofilm from biological filters proveduseful for comparing microbial commu-nities, but not for identifying specificMn-oxidizing bacteria. The results ofpolymerase chain reaction (PCR) testingshowed known Mn-oxidizing bacteriaPedomicrobium and Leptothrix to becommon in the filter biofilm. Correla-tion of the presence of these bacteria toMn removal or release was not part ofthe research.

Applications/recommendationsIt is important that utilities recognize

that eliminating the chlorine residual in thewater applied to filters, which have beencontrolling Mn, will likely cause a releaseof Mn from the filters to downstreamprocesses and/or the distribution system.The PIs recommend that utilities considerall alternatives to meet their treatment ob-jectives, before making the change fromIOCME to BAF for Mn control.

If chlorine must be eliminated, utili-ties should consider the source of the Mnin optimizing its control. For example, • If Mn is in the source water, consider

pretreatment using an upflow biological filter.

• If Mn is in the coagulant, consider a source for procuring the chemical that offers a product with less Mn, or an alternative coagulant that does not contain Mn.

• If Mn is in the sludge, process the sludge sooner to prevent the sludge blanket from becoming anoxic. Or eliminate the return of supernatant to the treatment process.Utilities intending to convert an ex-

isting filter, which was used to controlMn, to a biological filter should con-sider removing the media and replacingit with new clean media. Utilities wish-ing to improve the Mn-removal effi-ciency of existing biological filtersshould consider raising the pH of the ap-plied water. Enzymatic (intracellular)oxidation of Mn can be achieved in bio-logical filters at a pH of 6.5 or greater;increasing the pH above 7.0, increasesMn oxidation.

Effluent quality limits for mu-nicipalities discharging treatedwastewater into watershedshave become more stringent in

secondary treatment, followed by aSAGR.

SAGR processThe SAGR is an aerated gravel bed re-

actor, with a horizontal-flow hydraulicprofile. The module provides year-roundnitrification well beyond most total am-monia permit requirements for influentwater temperatures as low as 0.5oC

(32.9oF), making it ideal for post-lagoontreatment in cold climates. An added ben-efit of the process is effluent polishing toBOD5/TSS levels of less than 10/10mg/L. Test data from a demonstration fa-cility in Lloydminster, Saskatchewan,have also shown significant (90%+) re-duction of fecal coliform to less than 200CFU; in some cases this has eliminatedthe need for additional disinfection.

SAGR was developed primarily toprovide post-lagoon ammonia removalwithout abandoning existing lagoon treat-ment infrastructure. The performance pa-rameters and sizing for the process arebased on extensive testing performed onthe post-lagoon SAGR in Lloydminsterand a demonstration SAGR that was lo-cated in Steinbach, Manitoba.

The process can be utilized for nitri-fication following any secondary treat-ment process, including either aerated ornon-aerated lagoons. It is a clean gravelbed with a horizontal flow distributionchamber at the front end to distribute in-fluent wastewater across the width of theentire cell. The aggregate is submerged,

providing the necessary surface area forgrowth and attachment of a nitrifyingbiomass within the bed, and is sized tooptimize bacterial growth and hydraulic

flow. A horizontal effluent collectionchamber at the back end collects all thetreated effluent and channels it to thedischarge structure. Sizing of the bed isbased on influent flow and loading rates,expected influent water temperature,and the required rate of nitrification.

The SAGR process is very simple tooperate. There is no solids return tomonitor and adjust, or sludge to waste

and dispose of. The operations andmaintenance aspect of the process issimilar to the operation of a conven-tional diffused-air aerated lagoon. Theonly moving parts in the system are theblowers supplying oxygen to the SAGRprocess. A simplified control schememanages the day-to-day operation of theblowers. Blowers for the SAGR aresized to meet the oxygen requirementsfor nitrification and final BOD polish-ing only. This translates to significantenergy savings, that would otherwise berequired to run blowers for a conven-tional aerated lagoon system.

Mentone’s SAGR system consists of

two beds in parallel, with each bed han-dling 50% of the hydraulic loading. Noaeration was required in the lagoons tomeet the recommended lagoon effluentBOD5 feeding the process. It is esti-mated that over the long term, the oper-ator of the Mentone facility will spendan average of 30 minutes per day doinga systems check (visual inspection) andmaintenance.

It is estimated that 50% energy sav-ings are realized with this design com-pared to other systems achieving similareffluent quality. The trade-off is thehigher lagoon footprint required for thenecessary residence time. Since the ca-pacity was available at the onset of thesystem design, utilizing the existing in-frastructure was deemed the most cost-effective approach for Mentone. Usingthe existing lagoons provided cost sav-ings in both the construction and long-term operation and maintenance of thesystem.

Commissioning and performanceNelson Environmental Inc. provided

system commissioning and operationaltraining on March 24, 2011. Followinga two-week startup window, effluentquality from the Mentone facility is notonly meeting NPDES permit require-ments but is producing low effluent con-centrations averaging 6.5 mg/l BOD, 3

mg/L /TSS and 0.3 mg/L TAN year-round. The system design flow is 0.12MGD (454 m3/day).

The upgraded system in Mentone isan example of a cost-effective and effi-cient solution for WWTP operators inNorth America, who face the same reg-ulatory challenges and want to keeptheir existing lagoon system, whilemaintaining low operation complexity.

Water Treatment

volves boiling saline water and coolingthe purified vapour to produce virtuallysalt-free water. Three commonly usedthermal processes are:

1. Multi-stage flash evaporation(MSF). Incoming seawater in this processpasses through the heating stages. Beforereaching the first stage where flash-boil-ing occurs, it approaches the maximumtemperature using externally suppliedsteam. Fresh water is formed by conden-sation of the water vapour collected ateach stage.

2. Multiple effect desalination(MED). An MED unit evaporates sea-water in one or more stages at low tem-perature (< 70oC). Steam is condensedon one side of a tube wall while salinewater is evaporated on the other side.Energy used for evaporation is the heatof condensation of the steam. The MEDprocess is designed to produce distilledwater with steam or waste heat frompower production of chemical processes.

3. Vapour compression (VC). Me-chanical energy is used to compress thevapour to increase its pressure and tem-perature. Then this vapour is used as asource of thermal energy and the latentheat rejected during condensation isused to generate additional vapour.

4. Reverse Osmosis (RO) systems.In RO systems, saline water movesthrough a semi-permeable membraneunder high pressure. The large mole-

Desalination of seawater orbrackish water is a uniqueway to supply water fordrinking and industrial pur-

poses. In the oil and gas industry, saltwater is extracted along with the targetedoil and gas resources. In agriculture, sur-face or subsurface drainage water con-tains high concentrations of mineralsand salts that can be harmful to aquaticlife in receiving water bodies. In allthese cases, desalination systems can beused to reduce salinity and minimize ad-verse environmental impacts.

Installed desalination capacity aroundthe world has increased from 5 millionm3 in 1980, to more than 65 million m3 in2010. Municipalities, with 63% of in-stalled capacity in 2010, were the highestusers of desalination systems. Industrywas second, with 25.8%, followed bypower stations, irrigation, tourism andthe military.

Distillation and reverse osmosis (RO)are the most common technologies forproducing fresh water from saline orbrackish water. In 2010, about 60% ofthe installed capacity consisted of ROsystems, while about 34% were thermalsystems, and 6% were others.

An acceptable desalination plant isexpected to meet environmental regula-tions, be cost-effective in terms of con-struction and operation management,and have minimal costs associated withmonitoring and permit fees.

Despite the many benefits the tech-nology has to offer, there are concernsabout potential negative impacts on theenvironment, including concentrate andchemical discharges to the marine envi-ronment, emissions of air pollutants, andthe energy demand of the processes. De-salination plant waste includes high saltconcentrations, chemicals used duringpre-treatment and post-treatment, plantmaintenance and cleaning, and filterbackwash containing suspended solids,micro-organisms and organic debris,non-toxic and toxic metals.

Desalination processesThe thermal distillation process in-

cules of salt and other impurities cannotpass through the membrane, while thewater filters through.

5. Electro dialysis. Electro dialysis isan electrochemical process and involvesthe removal of salts by passing themthrough cation and anion membranes,leaving the water behind. This process ismainly used for brackish water.

Environmental issuesEnvironmental considerations are a

major factor in the design and imple-mentation of desalination technologies.All desalination processes generate alow-salinity product water and a high-salinity concentrate water. The mainlocal environmental impacts that arisefrom the desalination process are frombrine concentrates and from dischargesof chemicals in the desalination process.Energy intensity is also considerable, al-though resulting emissions of green-house gases should be examined on theinternational level (in relation to theKyoto Protocol). Local impacts areacute in comparison to global impactsand could thus be seen to be more sig-nificant.

From an environmental perspective,there are differences between seawaterand inland desalination plants. In addi-tion, thermal and RO systems have dif-ferent considerations and affect theenvironment differently. The common

factors that can be considered for all sys-tems are:

1. Impact on source water. Marinewater intakes can cause impingement andentrainment. That means both large ma-rine organisms like fish and/or smallaquatic organisms such as plankton, fisheggs and larvae can be trapped or en-trained with the intake water, causing in-jury and death to these organisms. Usingnear-shore wells can minimize this threat,but will increase energy consumption.

For inland plants, brackish ground-water is a common source for desalina-tion plants. Withdrawal of brackishgroundwater can harm the physical sus-tainability of the aquifer, with potentialfor subsidence or salt water intrusion.Especially when the aquifer is locatednear the sea or a water body with ahigher salt concentration.

2. Impact from concentrate. Brinewater produced by desalinationprocesses (sometimes referred to as re-ject water), is the main environmentalconcern. When the source water is sea-water, it requires exclusion of suspendedand dissolved solids. These solids are re-

jected with the unprocessed water, in-creasing its density and solids concen-tration, together with the chemicalsadded in the pre-treatment stage. If theprocess is thermal, the temperature ofthe reject water is higher than that ofseawater and can cause severe environ-mental impacts. In addition, increasingthe salinity of the seawater near the in-take can reduce the performance of thedesalination system.

Reject water from inland desalinationsystems is usually discharged into rivers,lakes or wells, and can have adverse en-vironmental impacts on the receivingwater body.

3. Issues with desalinated waterproduct. Not all constituents and con-taminants are removed during the de-salination process. This is more evidentin RO systems, because a small fractionof ions, especially monovalent ions suchas sodium and chloride, and dissolvedorganic molecules (e.g., some pesticidesor herbicides), can pass through to thepermeate water. Boron and bromide areexamples of two other potential contam-inants that can go through single-pass

RO desalination processes without beingremoved. Higher levels of boron maycause adverse health effects.

4. Impact from gas emissions. Theenergy used in the desalination processis primarily electricity and heat. Largeamounts of greenhouse gases are pro-duced by desalination plants due to highenergy requirements. RO technologygenerally requires less energy than otherdesalination technologies.

Mitigating environmental impactsDesalination projects require an envi-

ronmental impact assessment (EIA) studyto determine their impact on the environ-ment. The EIA considers all environmen-tal parameters and criteria. It evaluates thepotential impacts to air, land and marineenvironments and also proposes mitiga-tion measures to reduce them.

If a desalination plant is located nextto a power plant, desalination plant con-centrate can be mixed with the highervolume of hot cooling water that isbeing returned to the ocean. This dilutesthe brine and marginally lowers the dis-charge temperature so there is less of animpact on sea life. However, for inland

plants that are far from the sea, thismethod is usually not applicable.

It is also possible to co-locate the de-salination plant with wastewater treat-ment facilities so the brine can be mixedwith the freshwater discharge to achievea lower salt concentration. But in aridand semi-arid regions where water isscarce, even treated wastewater is valu-able. It is not advisable to lower thequality of the water, by mixing it with

highly concentrated salt water.Additives to feed water, including

pre-treatment or anti-scaling agents, areother sources of potential contaminationin reject water. Therefore, optimal use ofthese chemicals is critical to mitigatingthe negative environmental impacts.

Zero liquid discharge techniques areanother alternative in areas where surfacewater, sewer disposal and deep well in-jection are not possible, or are prohibited.

Reverse osmosis desalination system.

In this technique, solid waste from rejectwater is produced. It can be placed in alandfill but may pose environmentalproblems due to leaching of chemicalsand highly concentrated salt into ground-water.

Due to the similarity between seawa-ter desalination plants and power gener-ation plants in the intake and disposal ofwater from and to the sea, environmen-tal aspects of marine desalination sys-tems are known in some detail. Inlanddesalination, on the other hand, espe-cially with RO systems, needs morestudies and regulatory guidelines to pro-tect the environment.

Before starting a new project in in-land areas, knowledge of the environ-ment is essential. It can be obtainedthrough monitoring, data collection,comparison with similar projects, simu-lations and pilot studies.

tions normally have background chlo-ride concentrations of 15 mg/L, but withwinter road salt loading levels they werefound to be as high as 1,200 mg/L. At275 mg/L the concentrations are strongenough to pose a risk to aquatic biota ifexposed to these levels for four days orlonger.

The major implications of this type ofdamage to the ecosystem over long peri-ods of time include collapsing aquifers,severe degradation of water, and in somecases, total destruction of drinking andwell water sources.

EutrophicationAside from providing safe and

potable water for consumption, freshwater also plays a crucial role in mineralcycling that returns needed nutrients(phosphorus, nitrogen, oxygen and car-bon) into usable forms. These mineralsare cycled through water systems eitherthrough plant-animal interactions, orthrough seasonal turnovers that occur inspring and winter.

The availability of fresh potablewater in North America isoften taken for granted. How-ever, tests are now showing

that sodium chloride from winter salt ispresent in increasing concentrations infresh water sources.

Each year, Canada uses over 5 milliontonnes of road salt — sodium chloride(NaCl), magnesium chloride, potassiumchloride and calcium chloride — to im-prove the safety of winter roads. This in-evitably ends up in surface and groundwaterresources after snowmelt.

The serious concern with the ever-in-creasing use of road salts is that, if salin-ity were to continue to increase at itspresent rate, many surface waters wouldnot be suitable for human consumptionand would become toxic to fresh waterlife within the next century. This shock-ing prediction becomes more concern-ing as the years go by and no significantchanges are made to reduce the amountof road salts used.

As well as the abundant surface freshwater that Canadians enjoy, millions ofpeople depend on groundwater sources,aquifers and moraines as a main sourcefor drinking water, irrigation and indus-trial use. Damaging the quality of the re-maining water is exponentially increasingthe rate of aquifer destruction.

Road salt can spread up to 200 mfrom the road due to tire spray and snowremoval, and is absorbed into theground. This salt then seeps into theaquifers and moraines, causing signifi-cant erosion damage and mineral weath-ering that wholly destroys the structuralintegrity of the subterranean area. If thisoccurs, there is a risk of land subsidence,cracking of house foundations, and nat-ural drainage pattern change.

In Pine Creek, Ontario, investigationswere carried out to evaluate the conse-quences of road salting on undergroundwater sources. They found that 50% ofsalt applied to the roads accumulated inthe shallow subsurface and severely de-graded the quality of the region’sgroundwater. Groundwater concentra-

In a healthy body of water, there isturnover of colder and warmer layers ofwaters, mixing nutrients and oxygen.However, with high levels of salinity, thesalty water remains at the bottom due toits greater density, impeding the turnover.Without this important mixing process,oxygen supply in the water is significantlycut off to all organisms in that body ofwater, potentially leading to the collapseof the aquatic ecosystem. If the turnoverprocess is continually interrupted, it caneventually lead to eutrophication.

Species and individual eliminationWith constant seasonal influxes of

road salt in fresh water, a significant num-ber of species are being eliminated fromaquatic ecosystems. A test performed in26 ponds in Nova Scotia upholds this the-ory. The findings showed that the greaterthe chlorine (Cl) levels from the additionof NaCl, the fewer amphibian speciesthere were. Ambystoma maculatum (spot-ted salamanders) and Rana sylvatica

(wood frogs) were the key indicatorspecies due to their limited resilience todisturbances of their environment. The re-sult was that of the eight amphibianspecies identified, the maximum speciesnumber was six, and the minimum zero.The indicator species was the first to notbe found as Cl concentrations increased.

Although these results only includethe impacts of salt on amphibian biodi-versity, they can be extrapolated to manyother species. The elimination of a pred-ator or prey species in a pond or lakecreates a critical imbalance in theaquatic ecosystem and larger food web,changing the population levels of manyspecies significantly.

Alternatives currently usedIn Canada, a number of alternatives

to road salt have been investigated tohelp alleviate some of the aquatic dam-age. However, to date, these all haveother environmental impacts.

Calcium chloride has been used incombination with road salt because it isable to remain efficient at lower temper-atures. It emits heat as it dissolves,which melts the snow and ice faster than

NaCl can on its own. However, thiscompound is expensive and requiresgreater storage care as it must remaindry prior to release on the roads, in orderto remain efficient.

A salt-free highway topping has beendeveloped at Michigan Technology Uni-versity. This product is made of calciummagnesium acetate (CMA) and ground-up beer bottles; it is applied to roads be-fore a storm. The principle behind thismethod is that the ground glass from thebeer bottles provides a means of tractionfor vehicle tires. It has proven to workjust as efficiently as NaCl, and, duringthe trial in the Michigan area, it wasfound to eliminate some of the environ-mental consequences of NaCl.

However, it also interrupts turnoverand reduces the levels of dissolved oxy-gen in fresh water.

Grit has become a common additiveto the winter road maintenance schedulein order to provide more traction, whileusing less road salt. Although gritoccurs naturally and does not create thechemical and toxic changes that road saltdoes, it can be a significant nuisance.

Water Supply

In large quantities, grit has the abilityto block rivers and streams, interruptingthe natural flow of water and the migra-tion of fish. This occurs most often inroadside rivers and streams that draininto nearby bodies of water. Grit that istransported in the water flow increasesthe level of sediment floating in thewater, lowering the sunlight that canpenetrate through to the bottom. Thiscan impede the amount of photosynthe-sis that would otherwise occur. In turn,this reduces oxygen levels and can cre-ate difficult living conditions for plantsand animals alike.

When grit is ploughed off the roadsand piled up high in the drainage ditches,water cannot pass through. When this oc-curs, it is strongly correlated to lowerwater levels in underground systems,from which drinking water is drawn.

Using grit instead of or in combina-tion with road salt does not necessarilyensure the protection of fresh water andthe organisms within it.

crease road safety but has not been uti-lized. It is not as harmful to organisms,soil and water as the chemical applica-tions for de-icing. This compound has theadded benefit of increasing the absorp-tion capacity of oxide surfaces, which al-lows for healthier soil and greateragricultural productivity than NaCl.

A volcanic mineral marketed underthe name EcoTraction™ can also be usedto provide traction in the winter. The min-eral has a unique structure that allows itto absorb the thin layer of water on top ofice and embed itself firmly into the ice.It then acts like sandpaper, providing in-stant traction in the most slippery condi-tions. There are currently no knownnegative side effects of this mineral onwater, as it is inert and safe to ingest.

EcoTraction has not yet been used ona large enough scale to determine thelong-term implications. However, whatmakes this product significantly moreuseful as a winter road maintenanceproduct is its ability to adsorb toxinsfrom water and hold onto them, helpingto actively purify water for human con-sumption. When used correctly, 1 m3 of

EcoTraction can process up to 2,500 m3

of soiled water. The product is knownfor its ability to adsorb ammonia out ofwastewater.

There has yet to be a mineral or com-pound discovered with such high po-tential to maintain winter road safetywhile actually helping to protect the en-vironment.

Although a number of these alterna-tives have the potential to alleviate someof the stress on fresh water systemscaused by road salting, they are not usedbecause they are more expensive. Cur-rently, the main approach is to reducethe amount of salt used and to distributeit in a more efficient manner.

To achieve this goal, a number oftechnologies have been developed. Envi-ronment Canada has attempted to makesome modifications to the equipment forsafer distribution. It has installed a FixedAutomated Spray Technology (FAST)and an Advanced Road Weather Infor-mation System (ARWIS) that work to-gether to apply chemicals to roads in acalculated and controlled fashion.

This system has proven to be effective

in reducing accidents and traffic delays,and minimizing salt damage to the sur-rounding environment. However, as withall alternatives to road salting, these sys-tems have their own drawbacks, includ-ing the high cost of proper equipmentand training programs. While these sys-tems will use road salt more efficientlythroughout the winter, hundreds of thou-sands of tonnes will still enter the watersystem each year, threatening the futureviability of Canada’s drinking water.

Canada’s addiction to road salt iscontinuing to degrade water resourcesand damage plant, animal and crop cy-cles. It is imperative that we recognizethe deleterious effects that road salt ishaving on ecosystems across NorthAmerica and take steps to correct thisproblem.

The first of the forts was made upof a few wooden buildings, surroundedby a palisade, that was constructed bySamuel de Champlain in 1620 after hisdiscovery of the area in 1608. Cham-plain built a second fort, which he calledSt. Louis, in 1626. A third fort was con-structed in 1636 by Charles Huault deMontmagny who built over Champlain'ssecond fort during a 24-year construc-tion project, which included the firstchateau. The fourth fort was built in1693, followed by a new chateau thenext year. The Dufferin Terrace wasadded to the complex in 1879.

A 10m long section of 900 mm di-ameter perforated Solflo Max corru-gated HDPE pipe is tied in at the endand will vent any overflow, should thesystem reach maximum capacity.

Manhole heights ranged from 2 m to3.41 m. A clean stone cover was used towick away extraneous water. The system

was also covered with extruded poly-styrene insulation as well as a waterproofmembrane and an added geotextile pro-tective layer.

"This is a very innovative use of cor-rugated HDPE pipe," stated Tony Ra-doszewski, executive director of thePlastics Pipe Institute, Inc. "Mostly wesee its use in road work, under parkinglots and in other modern building proj-ects. For more than 200 years this was thehub of French and English rule in Que-bec and served as the official residenceand seat of power for most governors.”

The limited space and the age of thesite posed logistical challenges for theconstruction team, according to EricBlanchette of JES. "We had to make sure

all the pipe could fit between the newsupport columns. We couldn't use heavyequipment and it was like working in asmall basement. One advantage of HDPE

pipe is that it is light which made it easyto take sections under the Terrace.

"The other challenge was backfilling.We put in clean stone so we would havevoids between the stones that would takewater around the pipe. We surroundedthe whole system with non-permeablemembrane to protect and contain anywater volume inside."

The reason Parks Canada wanted aclosed-in stormwater retention systemwas because it would enable part of thearea under Dufferin Terrace to join themuseum. To protect this area and makeit possible for visitors to actually see andwalk around structures that date to the1600s, it had to be enclosed with wallsand windows. But by doing this,stormwater that used to come throughthe Terrace could no longer go into theground. This created an overflow of rainwater, which had to be detained before itflowed over the cliff and onto the housesand buildings below. The water had to beheld and later released at a specified rateinto the sewer system.

Champlain built on this site nearly400 years ago. With the new stormwaterretention system controlling waterrunoff and erosion, it will last for manyyears to come.

Biosolids Management

The Seymour-Capilano Filtra-tion Plant, which is part of theMetro Vancouver water supplysystem, is the largest of its

kind in Canada. Once it is running at fullcapacity, the facility will have the abilityto treat 1.8 billion litres of water per dayfrom the Seymour and Capilano water-sheds.

The challengeDewatering and sludge disposal are

two very important processes in thewater treatment cycle. The Seymour-Capilano Filtration Plant (SCFP) has adaily sludge handling and disposal ca-pacity of 80 tonnes.

Monitoring the screw conveyor’s mo-tion is crucial to keeping the sludge de-watering and disposal system runningsmoothly. If the screw stops because itbreaks or disengages from the motor,conveyance is interrupted and sludge be-gins building up in the conveyor system.

This type of stoppage can cause damageto the filter press, as more and moresolids build up.

Therefore, any interruption to thescrew’s motion has to be monitored andreported instantly. Operators can thentake immediate corrective action to pre-vent damage to the filter press and alsoto ensure that trucks are continuously re-ceiving the sludge. Monitoring the levelof sludge being loaded into the trucks isalso important.

The solutionThe SCFP uses process protection de-

vices from Siemens that consist of aMilltronics MFA 4p motion failure alarmcontroller and XPP-5 heavy-duty motionsensing probe.

The system detects any changes in themotion and speed of screw rotation. Ifthere is damage to the conveyor system,the alarm will stop the belt press and ma-chinery will not load any more sludgeonto the conveyor. The controller alsosends an alarm to the control system,which will shut down the press.

industrial applications including screwconveyor flights, tail pulley shafts, drivenpulleys, motor shaft sensing, belt or dragconveyors, bucket elevators, fans, andpumps.

The system works in conjunctionwith a Milltronics MSP-12 probe, whichcan be installed into new processes orretrofitted into existing equipment.

To keep truck load-outs efficient, the

plant uses non-contact ultrasonic levelmeasurement. This system consists of anEchomax XPS-15 transducer, mountedabove the filling area, and MultiRanger100 mounted at eye level to monitor lev-els of sludge while trucks are being filled.When a truck is filled to its maximum ca-pacity, a MultiRanger 100 notifies the op-erator, who then moves the truck awayand brings in the next one to fill.

With the help of these process pro-tection devices, plant staff are immedi-ately aware of problems and can react tothem quickly.

Case Study: Birchdale residentialcommunity

The proposed Birchdale residentialcommunity in North Courtice, Bow-manville, Ontario, was slated for devel-opment by both the local and regionalofficial plan processes. An environmen-tal assessment was carried out, resultingin recommendations for transplantinglocally uncommon plants.

The environmental consultant recom-mended that each locally rare plant bepotted and transplanted by hand. HenryKortekaas & Associates recommendedan alternative method using a skid steerto transplant “slabs” of vegetation. Slabs

During the development con-struction process in Ontario,if a site’s vegetation is lo-cally common in an ecologi-

cal sense, the standard practice is toremove all, or at least most of it. Maturewood lots, stream valleys and locally un-common vegetation are usually retainedas stipulated by approval agencies.

The development approval process isslow, and many vegetated sites or urbanedge farms are scheduled for developmentyears in advance through a municipality’sofficial plan process. There are “landbanks” owned by developers and whatwas once farmland now lies fallow.

Meanwhile, the former farm fieldsare being regenerated by early succes-sional woody plant species. Over time,significant portions of the site becomere-vegetated. After 10 to 20 years, thedeveloper’s earthmoving equipment fi-nally arrives and significant areas ofyoung vegetation are removed. However,there are alternatives.

For example, today's earthmovingtechnology can relocate significantswaths of young, existing vegetation.Large rubber-tired loaders with modi-fied steel buckets can now be used totransplant large areas of early succes-sional, understory plants, small woodedareas or even small streams. Wholeecosystems and their seed banks can bemoved if warranted. This will ensure thatcommon or rare plants and their ecolog-ical communities are relocated as a com-plete, functioning ecosystem.

Granted, plants cannot be too large,and soil depth and moisture conditionsmust be just right for this kind of relo-cation to be successful. The quality, typeand depth of soil and subsoil, as well asthe timing of transplanting, are ex-tremely critical. Late fall, winter or earlyspring are the best times to move plants,as they are in their dormancy period, andweather and temperature conditions arebest. Site conditions will also dictatewhen plants can be moved. Winter trans-planting when the ground is just frozenfor 10 to 12 in. is best. Machines canmove over the frozen ground, while still

of plants, with their entire root systemsintact, were moved to an appropriate lo-cation having generally the same or bet-ter soil, moisture, light and orientationconditions as the original site. The plantslabs were roughly 3 x 6 ft, with a topsoildepth of 8 to 10 in. In many cases, depthof topsoil and organic conditions wereimproved by this method, because theslab was placed over existing topsoil thathad been scarified.

etation of sugar maple and white ashsaplings. The site sloped towards a golfcourse pond, which had effectivelydrained the perched water table. This re-sulted in drier conditions for the maturemaple-beech-oak woodlot. It had beenstressed over the past seven to eightyears, resulting in the decline and deathof many of the mature trees.

The solution was to move the under-story vegetation to preserve the woodlot.

Existing understory vegetation was com-posed of young sugar maple saplings,avidly racing to the light openings left inthe canopy by the dead or dying trees.They were growing in sandy loam soilsabout 8 to 10 in. thick over subsoil ofsand and gravel. They can be moved, notindividually, but in slabs of frozen soil,roots and plants that are 12 – 16 in. thickby 8 ft by 8 ft. Prior to the removal of themature woodlot, as part of the develop-

ment process, large, rubber-tired frontloaders can move much of the understoryvegetation that is regularly cut down.

Native tree saplings tend to growmore successfully if moved in this man-ner, rather than through transplanting in-dividual trees using pots. This is due totheir extensive, intertwining root sys-tem. The intent is to place the slabs ofsaplings in their final location if possi-ble. If necessary, temporary holdingareas can be designated for the saplings,which can then be moved again whenthe heavy construction is complete andreceiving areas are ready for planting.

The slab technique of transplantinghas been used in several other projects,resulting in a more successful preserva-tion of natural vegetation while achiev-ing significant cost savings. Largeearthmoving equipment can, if used inan appropriate manner, provide verypositive environmental benefits.

be Class 1 or 2) that are close to exist-ing established industries. Identificationof an area as Class 4 requires formalconfirmation from the land-use planningapproval authority for the area.

Mechanisms for designating Class 4areas have been left to municipalities todevelop. Some “suggested” methods ofimplementation range from official plandesignations, inclusion in the zoningbylaw, down to a simple letter from thechief planner. Existing Class 1 and 2areas cannot be re-designated as Class 4areas, unless they are torn down and re-developed.

The 2010 version of the draft guide-line also included a Class 5 designation,for areas adjacent to airports or heavilytravelled rail corridors. This was deletedfrom the 2011 draft, and the definitionof ambient background noise was alsoaltered to provide a method to allow railand aircraft noise to be considered. It isuncertain whether the Class 5 designa-tion will return in the final guideline, orif the revised ambient background cal-culation methods will remain in the final

The Ontario Ministry of the En-vironment is in the process ofreplacing its existing noiseguidelines for industrial ap-

provals and land use planning. The ex-isting stationary (industrial) noiseguideline Publications NPC-205 andNPC-232, and that for Land-Use Plan-ning (LU-131), are to be replaced witha new combined comprehensive guide-line, called NPC-300.

NPC-300 drafts were circulated inNovember 2010 and April 2011, and thenew guideline is set to be approved thisyear. The draft guideline contains severalchanges and additions that will affectnew infill development, and how indus-tries determine compliance.

On the whole, the new guideline willbe helpful in assessing industrial noiseimpacts on new developments; however,some specific types of noise sources andindustries may be adversely affected.Readers are urged to review the drafts tosee how they may affect their own opera-tions. Although the new guideline is stilla draft, concepts from it are already beingused in some development applications.

This article focuses on how the draftguideline addresses “stationary” indus-trial noise. The assessment techniquesfor road, rail and aircraft transportationnoise for new residential developmentwill remain largely unchanged.

New area classificationsAs in the original predecessor publi-

cations, the NPC-300 guideline limitsdepend on the sound characteristics ofthe area where the receptor is located,with designated classifications princi-pally distinguishable on the basis of theamount of man-made noise present. Theexisting “Class 1 – urban,” “Class 2 –semi-rural” and “Class 3 – rural” areaclassifications from the original guide-lines remain, with Class 3 being themost stringent.

A new area classification, Class 4,has been created, which has higher (lessstringent) guideline limits. This designa-tion is intended for infill residential de-velopments (areas that would otherwise

document.New definitions for points of

receptionStationary (industrial) noise must be

evaluated at all noise-sensitive points ofreception. The definition of point of re-ception has been expanded significantly,and borrows heavily on the conceptsfrom Publication LU-131. For existingresidences, points of reception include:• Outdoor ground level amenity spaces

within 30 m of a facade and at a height of 1.5 m.

• Balconies and elevated terraces, if they are the only outdoor area for the occupant, are greater than 4 m deep and are unenclosed.

• The plane of windows associated with noise-sensitive spaces.

Guidance is also provided on points ofassessment for “zoned for future use”land uses:• Where a building is approved under

Section 41 of the Planning Act, or where a building permit has been issued, but where construction has not begun, the point of reception is at the

centre of the proposed building and at heights representing noise-sensitive windows.

• If the location is a noise-sensitive vacant lot, where no planning or building approvals have been provided, then guidance is given depending on the lot size. The point of reception should also be consistent with the surrounding zoning and typical building pattern in the area.The latter definitions are focused on

urban and suburban land uses, and offerlimited guidance on assessment in ruralareas. For example, most agriculturalzonings allow for residences to be con-structed. It is unclear from the definitionif a “house” must therefore be assumedto exist on all agricultural lots, evenwhen one is not anticipated (for exam-ple, where an individual farm owns sev-eral lots). This could affect ruralindustries, such as grain dryers and feedsuppliers (and other agri-businesses)and pit and quarry operations. It is to behoped that this will be clarified in thefinal document.New guideline limits and assessment

time periodsThe draft NPC-300 guideline pro-

vides new guideline limits. Like the pre-vious guidelines, limits are provided forsteady and varying sound (cumulativenoise from fans, HVAC units, trucks,etc.), as well as impulsive noise (ham-mer hits, trucks coupling or uncoupling,punch presses, pneumatics, etc.). Unlikethe previous NPC documents, the guide-line provides separate limits at outdoorpoints of reception and planes of win-dows of noise-sensitive spaces. The lim-its for steady and varying noise areshown in Table 1.

The limits for Class 1, 2 and 3 areasremain essentially unchanged, and as-sume open windows. The new Class 4limits are +5 dB higher for outdooramenity spaces, and +10 dB higher forthe plane of noise-sensitive windows.The higher window limits are meant toreflect the concept that the windowswould remain closed, and that air condi-tioning would be provided for these re-ceptors.

It is particularly important to notethat, unlike the predecessor land-use ap-proval guideline LU-131, the draft NPC-

Noise Pollution

300 limits do not distinguish betweendaytime and night-time points of recep-tion for windows. The daytime guidelinelimits will need to be met at former

“night-time” points of reception, such assecond-storey bedroom windows. Thiswill affect industries that have previ-ously relied on having “daytime” opera-

tions only, and that relied on berms andnoise walls to provide noise mitigation.Such facilities include many pits andquarries, warehouses and ancillarytransportation facilities. These facilitiesmay require significantly higher (andwider) earthen berms and noise walls tomitigate noise levels.

Revised noise limits are also providedfor impulsive noise sources. Again, thelimits are now provided at outdoor pointsof reception and at the plane of noise-sensitive windows. The limits for “spe-cific impulsive sounds” in NPC-205have been removed. This may affectcompliance at some metal working op-erations, and their noise guideline limitsmay decrease by 5 dB (become morestrict) during the night-time period.

In addition, the new limits replace theprevious definition of “frequent” versus“infrequent” impulses. This essentiallydefined infrequent activity as fewer than20 impulses occurring in a two-hourtime frame. The new guideline has asliding scale, depending on frequency ofimpulses per hour, which are shown inTable 2. The new lower limits and cor-

Table 2: Exclusion Limits for Impilsive Sound (LLM(1hr) Values, dBal)

responding number-of-impulse thresh-olds will again potentially affect indus-tries that previously relied on the“infrequent” categorization. Exampleswould include industries relying onheavy trucking, with transport truckcoupling and uncoupling, and those re-lying on outdoor storage of products,which may generate impulses whenbeing moved.

The sound level limits for emergencyequipment during non-emergency peri-ods, such as normal testing and mainte-nance, have also been relaxed (made lessstringent). Examples include emergencyelectrical power generators used forstandby power. The new limits for suchequipment would be 5 dB higher thanthe values in Tables 1 and 2.

Predictable worst-case scenariosThe “predictable worst-case sce-

nario” that is the subject of the assess-ment has been clarified. Regular, routineoperations and equipment are to be in-cluded. “Infrequent” events are also in-cluded, if the operation of the equipmentoccurs twice a month or more, for atleast half an hour on each occasion.Routine testing and maintenance ofemergency equipment are also part ofthe assessment, but are subject to theless stringent +5 dB limits.

The 2010 draft noted that for land useplanning assessments, the potential fu-ture expansions of the industry shouldbe taken into account, either by review-ing the industry’s corporate plans, orbased on the restrictions in its Compre-hensive Certificate of Approval. Thislanguage is missing from the 2011 draft,although apparently this does not repre-sent a policy shift at the MOE.Receptor-based mitigation methods

Unlike in NPC-205 and 232, recep-tor-based noise mitigation measures arenow allowed to be used by the industryin assessing guideline compliance. Ac-ceptable methods include:• Receptor-based outdoor noise control

measures, such as berms and barriers.• Receptor-based site planning noise

control measures, such as height restrictions and interior layouts.

• Receptor-based “on-building” noise control measures, for buildings in Class 4 areas.The April 2011 draft suggests that,

whenever receptor-based noise mitiga-

tion measures are used, they should besubject to a three-party, legally bindingagreement. This would be between thedeveloper, the municipality and the in-dustry, registered on title, to ensure theirinstallation and maintenance. Concernhas been raised on implementation, andwhether this incorrectly places the in-dustry in an approval role. The 2010draft only required a legal agreementwith the industry, when at-source miti-gation was to be installed.

Receptor-based “on-building” noisecontrol measures could include suchthings as sealed windows (where al-lowed under the Ontario Building Code,or OBC), barriers on portions of bal-conies, or blinder walls that shield theaffected windows. An innovative ap-proach provided in the guidelines is theuse of an “enclosed noise buffer” bal-cony. An “ENB balcony” is essentiallyan enclosed solarium that overlaps theaffected windows. It can be equippedwith operable exterior windows, andmust be less than 2 m deep. The facadeseparating the balcony from the indoorsmust include exterior grade walls, win-

dows and doors meeting OBC minimumrequirements. The concept is illustratedin Figure 1. ENB balconies may only beused for high-rise, multi-tenant build-ings in Class 4 areas.

The proposed NPC-300 guideline ad-dresses many of the uncertainties and in-consistencies in the previous NPC-205,232 and LU-131 guidelines. The new,higher guideline limits and receptor-based mitigation measures may make in-fill and brownfields redevelopmenteasier. This will help industries maintaincompliance, developers build, and mu-nicipalities meet the objectives of On-tario’s Places to Grow Act.

Uncertainties remain as to how thenew guidelines will be implemented,and how the transition from the currentNPC guidelines to the new guidelinewill be addressed. This will be importantfor the industries noted above, whereguideline changes may affect their com-pliance status.

sources, Niagara Peninsula ConservationAuthority, Niagara Escarpment Commis-sion and Enbridge Pipeline Inc., developeda remedial solution that would meet the re-quirements and needs of all stakeholders.

The solution required a life cycle costanalysis approach that accounted for allenvironmental, social and economic im-pacts and aspects associated with the re-quired treatment objectives. This triplebottom line evaluation determined thatan onsite wetland treatment systemwould meet the treatment objectives,minimize long-term operational and

maintenance costs, and incorporate thenatural characteristics associated withthe surrounding riparian habitat.

There are generally two types of con-structed wetlands that could have beenimplemented to provide treatment: afree-water surface (FWS) system or asub-surface flow (SSF) system. How-

The Rice Road Landfill servedthe communities of Thorold,Pelham and Fonthill in the Ni-agara Region of southern On-

tario from 1949 until it was closed in1986. It was built in a deep ravine that ispart of the headwater area of TwelveMile Creek, which is the only cold-waterfishery in the region.

To maintain the hydraulic connectionbetween upgradient lands and TwelveMile Creek that was originally providedby the ravine, a corrugated steel pipe(CSP) was installed in the ravine duringthe early days of landfill development.

In 2000, leachate-affected dry-weather baseflow and stormwater fromthe CSP were identified as adversely af-fecting surface water conditions inTwelve Mile Creek. Un-ionized ammo-nia and phosphorus discharges were ofparticular concern.

The City of Thorold, the owner of thesite, has a population of approximately18,000. The closed Rice Road Landfillis the only waste management facilitywithin the City’s jurisdiction, therefore,resources for management of the reme-diation project were not readily avail-able. As a result, the City looked topublic-private partnership models wherea turnkey approach could be utilized toappropriate risk, optimize schedule andmaximize project value.

It was determined that the City’sgoals could be achieved with a projectdelivery package consisting of: a) Project design and approvals;b) Project management;c) Construction and procurement; andd) Operations, maintenance and

management.To develop and implement a solution,

the City retained Integrated MunicipalServices (IMS), a subsidiary of theWalker Environmental Group, and its de-sign/build/operate project team, consistingof Urban and Environmental Management(UEM) and Aquatic Sciences Inc. (ASI).The project team, in cooperation with reg-ulatory authorities such as the Ministry ofthe Environment, Ministry of Natural Re-

ever, mosquito habitat was a concernwithin the area, so the FWS system wasnot seen as desirable in this situation. Bykeeping flows sub-surface, odour con-cerns could be eliminated (particularlyas oxygen status is kept high via the im-plementation of a free draining system).Also, keeping flows within a porousmedia offered a significant level of ther-mal insulation, that has allowed for con-tinued operation during cold periods.

Formal experimentation by the U.S.Environmental Protection Agency andEnvironment Canada, at Niagara-on-

the-Lake in the early 1990s, demon-strated that SSF wetlands could operatesuccessfully during extended periods offreezing weather. These experimentswere based on very successful cold-cli-mate research that had been undertakenin Norway.

wetlands demonstrated that vegetativethatch from cattails and/or bulrushesfurther insulates wetland cells from theimpact of cold air. It is also beneficial tocreate wetland cells that are as deep aspossible, to allow for the storage of ther-mal energy.

With these points in mind, the proj-ect team determined that the Rice Roadwetland treatment system would best bedesigned as a sub-surface vertical flowwetland. It required a design whichwould reduce un-ionized ammonia andtotal phosphorus loading from leachate-affected stormwater coming from thesite. It was also determined that an SSFwetland should minimize or negate ad-verse cold weather impacts on biologi-cal activity and hydraulic efficacy.

Designing the wetlandFlows discharging from the landfill

were assessed to determine optimal con-figuration for the treatment wetland.Water quality/quantity analyses showedthat baseflow discharging from the land-fill was highest in terms of contaminantconcentrations and long-term, cumula-tive loadings. It was decided that the in-fluent to the wetland system would bevolumetrically controlled to accept thepeak spring baseflows. The target base-flow rate entering the wetland systemwas set at 13 m3/day.

A combination of weir and orificecontrol was utilized at the inlet to thewetland structure to assure appropriatebaseflow influent rates. The wetland sys-tem was further protected through the

design and implementation of a systembypass weir.

Since Twelve Mile Creek is a partic-ularly sensitive waterway, stringent ef-fluent objectives were set. Totalphosphorus limits were set at 0.03 mg/Land un-ionized ammonia concentrations

were not to exceed 0.02 mg/L for flowsof 13 m3/day.

fuel or electricity. The design was basedon a first-order plug-flow reactor model,which resulted in a total wetland surfacearea of 1,100 m2 over three cells in se-ries, each with a 0.67 m depth.

The design strategy required a treat-ment media consisting of a medium-to-coarse sand with a porosity of approx-imately 30%. An evaluation was con-ducted of locally available materials todetermine a suitable media. Several ma-terials were evaluated, including an un-washed, well-graded native sand, awashed, uniform filter sand, a uniformcrushed limestone manufactured sand,and a uniform crushed limestone, 1/8-inch chip.

Laboratory analysis of the four mate-rials included porosity, grain size analy-sis and coefficient of uniformity. Basedon this analysis, it was determined that a2:1 blend of filter sand and 1/8-inchcrushed limestone chip, respectively,would provide an optimum porosity, co-efficient of uniformity and effective sizefor use in the SSF wetland treatmentsystem. Both materials could be sourcedlocally to maintain the economic viabil-

wetland cells, a pair of primary treat-ment chambers were specified to re-move solids and any oils, grease or“floatables” that might cause the cells’porous media to become clogged. Soilbearing capacity estimates indicated thattwo 12.5 m3 concrete tanks (pre-fabri-cated septic tanks) could be used for thispurpose.

Construction of the wetlandDue to the lack of available land, the

SSF wetland system was sited at the bot-tom of the north slope of the landfill,within a valley that contained a seasonalcreek. Developing the treatment systemwithin this valley created several chal-lenges. A work permit was requiredfrom the Ministry of Natural Resourcesand construction was only allowed be-tween May 30 and September 1. Thesoft, saturated organic soils, with a lowbearing capacity were another chal-lenge. A geotechnical assessment wasrequired to ensure these soils would sup-port the system infrastructure, as well asto ensure that construction activities

would not affect the steep side slopes ofthe ravine.

An additional complication was thatof having to cross the Enbridge Pipeline

across an active inter-provincial 24-inchcrude oil pipeline and an inactive 18-inch pipeline. All necessary approvalsand engineering were needed to ensureconstruction activities did not affect thepipelines.

Staging of the entire construction ef-fort had to be closely coordinated as siteaccess was only available via the southend of the ravine. This, combined with thesoft soil conditions, required the use ofgeosynthetics and temporary access roadconstruction to allow heavy equipment tooperate on the soft organic soils. A 90 mtemporary access road underlain by anon-woven geotextile was constructedthroughout the length of the ravine.

Heavy equipment worked off the endof the road, and as construction pro-gressed, the road was removed to makeway for the SSF wetland treatment sys-tem. Specialized, six-wheel-drive articu-lated haul trucks were needed totransport excavated soils out of the val-ley and treatment media back in for usein the wetland cells.

Following design and approvals, theSSF wetland was fully constructed

within two months in late 2005 at a costof $200,000, including design, approvalsand construction. It was commissionedin February 2006.

Operations and performanceThe certificate of approval (CofA) is-

sued by the Ministry of Environment setdischarge limits on biochemical oxygendemand (BOD5), total suspended solids,un-ionized ammonia, total phosphorus,dissolved oxygen and pH. These param-eters are sampled every second week inthe raw influent, primary effluent andtreated effluent for compliance pur-poses. The CofA initially requiredweekly sampling of these parameters,but due to consistently good perform-ance, the MOE has authorized a reducedsampling frequency.

These same locations, plus the sys-tem bypass, are also sampled every sec-ond month for a longer parameter setthat includes additional conventional pa-rameters and metals. Iron, a commonlandfill-related metal, is reduced frominfluent concentrations of 20 mg/L totypically less than 0.03 mg/L in thetreated effluent. This is well below the

provincial water quality objective forsurface waters of 0.3 mg/L.

In addition to water quality sampling,influent flow, effluent flow and bypassflow are continuously monitored at thesite using battery-powered level meters.Operation and maintenance includeswinterization with a 0.5 m straw thatchblanket over the upstream 30% of eachcell, periodic removal of invasivespecies, flushing and cleaning of theweir and sediment chambers as required,twice-yearly exercising of valves, andflow-meter maintenance.

Since 2009, Integrated MunicipalServices and the City of Thorold haveutilized the wetland treatment system asan outdoor learning opportunity. Stu-dents from Niagara College’s Ecosys-tem Restoration and EnvironmentalTechnician programs have been onsite tolearn how the wetland functions and toexercise their newly acquired skills andeducation in a practical setting. Most re-cently, the students have assisted withthe winterization of the wetland, con-ducted plant inventories, and helpedwith the management of invasive speciesand the improvement of habitat features.

In the future, the wetland will featuresignage for future student education andoverall public awareness about the im-portance of the wetland treatment sys-tem and all its features.

Following a brief startup period, thetreatment wetland at the closed RiceRoad Landfill has provided consistent re-moval of ammonia, phosphorus and otherparameters listed in the site CofA. Thisincludes excellent cold-weather perform-ance. A new investigation has begun atthe site to examine the feasibility of in-creasing the peak flow rate through thetreatment system, to reduce the frequencyof wet-weather bypass events.

Veolia introduces a newMBR

Veolia has introduced Memthane®, ananaerobic membrane bio-reactor.

Developed by Veolia’s subsidiaryBiothane, it combines Biothane’s anaer-obic biological wastewater treatment andPentair X-Flow's ultrafiltration (UF)membrane separation process.

Memthane can be used to treat highstrength, high solid wastes found in in-dustries such as distilleries, dairies(whey), bio-ethanol producers and in-stant coffee plants, which were previ-ously considered untreatable from aneconomic standpoint. It produces a highquality effluent that can be dischargeddirectly to the sewers or often easilyreused. Nutrients can be recovered forfertilizer production. With a COD re-moval efficiency of >98%, this powerfulgreen energy source can make plants en-ergy self-sufficient, reducing depend-ency on costly fossil fuels.

Tervita markets new wastedisposal technology

Tervita Corporation has entered into anagreement to license and market a newtechnology that will treat evaporatorblowdown in a more responsible, sus-tainable and cost-effective way for steamassisted gravity drainage (SAGD) opera-tors .The technology, called THi-pHEC™(Treatment of High-pH Evaporator Con-centrate) was developed by Veolia WaterSolutions and Technologies. Evaporatorblowdown is the remaining waste solu-tion after produced water has beentreated.

Many SAGD operations produce waste-water that contains dissolved silica main-tained in a high pH solution. This wastesolution is not suitable for typical deep wellinjection and is currently disposed of incaverns. Tervita’s new treatment will re-move silica from the wastewater and createa solution that will meet criteria for Class1b disposal and a dry solid suitable forClass 2 landfill disposal.

Tervita is currently engineering a pilotplant for this technology and expectsconstruction to be complete by April2013, with plans to move to a SAGD

American Water receivesgrant for monitoring project

American Water has received a grantfrom the Water Research Foundation toconduct a joint research project withUtah State University to measure the fre-quency of backflow through residentialwater meters. The project is titled, CaseStudies to Identify Occurrence, Accu-racy and Causative Factors of ReverseFlow as Measured by Meters.

By examining and quantifying therate of residential backflow occurrencesit will be easier to determine if there areany associated public health risks. Amer-ican Water and the Utah State Universitywill monitor the occurrence of backflowas reported by “intelligent” water metersand determine the accuracy of these me-ters as they flow in reverse. The water in-dustry will benefit from this research byunderstanding how often water flow inresidences reverses itself and it will helpdevelop ways to investigate and mitigatethese occurrences.

Ontario proposes protection for the

Great Lakes

The proposed Great Lakes ProtectionAct and Great Lakes Strategy look toarm Ontario with tools and resources torestore and protect the Great Lakes. TheGreat Lakes Strategy outlines six goalsto establish priories for future action:empower communities; protect water;improve wetlands, beaches and coastalareas; protect habitats and species; en-hance understanding and adaptation; andensure environmentally sustainable eco-nomic opportunities and innovation.

Working with the Great Lakes Strat-egy, the Protection Act would:

• Provide new tools for the Ontariogovernment to protect Great Lakesbeaches, wetlands and other coastal areas.

• Authorize the Minister of the Envi-ronment to set targets, and authorize thedevelopment and implementation of ini-tiatives to address particular Great Lakesproblems.

• Establish a Great Lakes Guardians’Council which would be led by the Min-ister of the Environment and includeother ministers with Great Lakes re-sponsibilities, as well as representativesfrom First Nations and Métis communi-ties, Ontario ministries, municipalities,environmental groups, the science com-munity, farmers, industry, recreation andtourism sectors.

Report will help protectwater resources

Nova Scotia will be better able to protectwater resources with a watershed assess-ment report released by the province andDalhousie University.

"This study meets a goal in Water ForLife, our water resource managementstrategy,” said Sterling Belliveau, Envi-ronment Minister. “It will help us focusour efforts on the water supplies that areat the most risk to protect them today andfor future generations."

The provincial watershed data inven-tory in the report is the first of its kind inNova Scotia. The province invested$29,000 in the Dalhousie University re-search project, and staff from the depart-ments of Environment and NaturalResources participated in the study. Thesecond phase of the project will gathermore data on the province's water man-agement practices and report on the in-formation at a local level.

Climate change projectsnearing completion

Projects have been undertaken by the At-lantic Climate Adaptation Solutions As-sociation to increase the ability ofcommunities to prepare for the effects ofincreased flooding and land degradationlikely to take place due to projectedchanges in the region's climate. Fundinghas been provided by the government ofNew Brunswick, Natural ResourcesCanada and municipal partners.

Of the six projects chosen in 2010 inconjunction with provincial officials, twoare nearing completion, while the otherfour are in progress and will be madepublic this fall. The first phase of the

studies, including collection of data,mapping, analysis and risk assessments,is complete and the next phase, whichwill include community engagement,will begin in the weeks to come.

A study based in the Tantramar regionof New Brunswick, focuses on the risk totheir infrastructure. The project highlightsthe areas most vulnerable to flooding.“This information, along with climatescenarios, paints a very clear picture fromwhich planners and decision-makers mustdevelop adaptation solutions at the locallevel,” said Tracey Wade, with the Tantra-mar Planning District Commission.

Another of the projects is in GrandFalls, New Brunswick. Adaptation solu-tions within the town will provide offi-cials with the knowledge and toolsurgently needed to mitigate erosion is-sues along all three major watercourseswithin municipal boundaries.

All of the data collected will be sharedand discussed at a November 15 – 16 con-ference in Fredericton, New Brunswick,hosted by the Atlantic Climate AdaptationSolutions Association.

Canada and Saskatchewanworking together

Canada's Environment Minister PeterKent and Saskatchewan's Minister of En-vironment Ken Cheveldayoff have an-nounced that they are working towardsan equivalency agreement on coal-firedelectricity greenhouse gas regulations.

The agreement would avoid duplica-tion of effort and regulations to controlgreenhouse gas emissions. As long asprovincial regulations achieve an equiv-alent or better environmental outcome,federal regulation would not apply. Bothministers stressed the importance of al-lowing Saskatchewan flexibility in re-ducing GHG emissions, including cleancoal and carbon capture and storage.

Saskatchewan is the second provinceto work with the Government of Canadaon an equivalency agreement for coal-fired electricity regulations, with theGovernments of Canada and Nova Scotiahaving made a similar announcementearlier this spring.

In August 2011, the federal govern-ment proposed new regulations for theelectricity sector that will apply a strin-gent performance standard to new coal-fired electricity generation units andthose coal-fired units that have reachedthe end of their economic life. Final reg-ulations are expected to be publishedlater this summer.

Tackling emissions from coal-firedelectricity generation, which represents11 per cent of Canada's total greenhousegas emissions, will go a long way towardsmeeting Canada's target of a 17 per centreduction in total greenhouse gas emis-sions below 2005 levels, by 2020.

Shell Canada fined for releasing sodium bisulfite

Shell Canada pleaded guilty in PeaceRiver, Alberta, for releasing a substanceharmful to fish into fish-bearing waters.The company was fined a total of$225,000.

The offence relates to the spill of achemical solution, mainly containingsodium bisulfite, into the Peace River onAugust 28, 2009. The release was causedby a drain valve being left open on achemical tank system while it was beingfilled. The open drain valve emptied ap-proximately 12,500 litres of the chemi-cal into the Peace River.

The company was fined $22,500 forthe offence and was also ordered to pay$202,500 to the Environmental DamagesFund (EDF) to be used to promote theconservation and protection of fish andfish habitat in the Peace River.
