still far from balanced.“In the early 1990s

there was a real push to get women studying en-gineering and non-tradi-tional elds and I thin that helped a lot,” said Hill. The environmental industry seems to have more women wor ing as operators, technicians, or engineers, which Hill at-tributes, in part, to com-panies dealing a lot with government clients.

“Government has been very open to promotion and loo ing at companies and services with blinders on,” said Hill. “ They are not loo ing at gender or race when they select services and people.”

Indicators of that push in the 1990s are evident when loo ing at the com-position of female politicians. Of the 11 women who have served as rst minis-ters (premiers and prime minister), over half too of ce in the past si years, with the rst, ita ohnston, premier of rit-ish olumbia, ta ing of ce in 1991.

This snowball effect of women gain-ing leadership roles can be seen in the associations which represent and bring together STEM professionals and sales-persons.

ennifer ose, manager, special pro -ects, engineering and public wor s with the City of Vaughan organized this year’s International Women’s Day event for the Ontario ublic Wor s ssociation. She noted that ust within O W , women are serving as president of the associa-tion, with increasing fre uency. etty Matthews-Malone with iagara egion, is the current president.

“This shows that women are valued, not only in the wor place, but in a public wor s association,” said ose. “Events li e the Women’s Day couldn’t be held without full board support.”

or women wor ing in a still male dominated industry li e public wor s, getting together with peers to share challenges and e periences are invalu-

trending topic circulating in social media and news sites on the days surrounding Women’s Day this year, was

attention on women in science, technol-ogy, engineering and math careers, also nown as STEM.

International Women’s Day, held on March 8, celebrates the accomplish-ments of women, dating bac to 1908 when 15,000 women marched in New

or City, demanding shorter hours, bet-ter pay and voting rights.

In late March, I watched my brother participate in the itual of the Calling of an Engineer at Western University in

ondon, Ontario. While I was e cited at seeing my younger sibling move to-wards becoming a professional engineer, I was intrigued by the demographics of his classmates, speci cally the paucity of female students.

While women aged 5- ma e up 66 per cent of university graduates in non-STEM programs, they only account for 23 per cent of engineering graduates. Furthermore, according to Statistics Canada, that group of women engineers ma es appro imately 5000 less annual-ly than their male peers.

Obviously there is wor to be done. Yet efforts towards gender equality, which ramped up in the 1990s are show-ing their results. Nearly 40 years ago, when my grandmother, Sandra Davey was secretary-treasurer of the Water En-vironment ssociation of Ontario, there was only one female member in the association. Now, not only do women ma e up roughly 20 per cent of WE O’s membership, but many serve on the as-sociation’s board.

I spo e with WE O resident Chris-tine Hill, .Eng. who is a senior e ec-utive with XCG Consultants. She said that, upon graduating university in 1989, only three per cent of Professional En-gineers Ontario members were women, a shortfall which was targeted by gov-ernment and the industry. Currently, out of PEO’s 77,460 licence holders, 7,736 are female, which is a large increase yet

able said ose.“The spea ers are usu-

ally re ecting bac on their own careers and lives and these stories are often quite inspiring,” said ose.

Despite improvements and progress in attitudes towards women, they still can come up against barri-ers and insults.

I spo e with Michelle yle who is in her nal

year of mechanical engineering at West-ern University. She stressed the open-ness towards women in school and in her internship placement, but she had once been told by an older man she quic ly noted that he was not an engineer—that it was her loo s, rather than her e per-tise, which had granted a placement.

s a whole however, far more oppor-tunities and outreach programs e ist now than 30 years ago, or even ve years ago.

“There are a lot of opportunities out there for women,” said Lyle. “Even since high school, you see more adver-tisements and e posure of programs.”

Engineers Canada has a “Women in Engineering” webpage, and states that their organization is “dedicated to in-creasing the participation of women in the engineering profession.”

Professional Engineers Ontario also has a Women In Engineering Group, who are active in going to high schools and en-couraging young women to thin about a career in science and technology.

For industries and professions which are worried over a looming labour short-age, educated and s illed women are an immense resource. While there is a gen-der wage gap, STEM careers, especially engineering, carry higher relative sala-ries, ample opportunities and low unem-ployment gures.

Li e many social ustice issues, strides in equality deliver economic bene ts.

Cover Story

It’s anything but black and white. Some, while seeing the world in 20/20, only see themselves. Others may look to the world with a clear

vision o how they can bene t those around them – even when they them-selves are losing sight. Such is the case for Jim Gehrels, founder of Lifewater

anada, a non ro t humanitarian orga-nization that helps people in developing countries.

Gehrels has never let an obstacle get him down. He is legally blind, having only ve degrees of sight due to an incurable genetic disease. In 1993, he used his experience as a hydrogeologist and made a trip to Kenya with Life-water International. It was during this trip that Gehrels discovered Lone Star Drills, and made the decision to start his own non-pro t.

Founded in 1995, Lifewater Cana-da is run by professional well drillers, hydrogeologists, environmental spe-cialists and nurses who volunteer their time and energy to equip the rural poor in Africa and Haiti with portable Lone Star drill rigs and other simple equip-ment. Lifewater Canada also trains workers to build wells and washrooms at orphanages, clinics, schools and vil-lages where people have been drinking from stagnant swamps without access to indoor toilet facilities.

To run a successful operation, Life-water Canada focuses on keeping costs down. In addition to being run completely by volunteers, it uses sim-ple technologies and donor funding to make projects affordable. Lifewater Canada also trains local workers and encourages community participation in construction projects.

A shared visionGehrel’s rst well-drilling journey

was to Liberia, a country in West Af-rica, where despite an ongoing civil war, he joined a group of volunteers and helped drill wells to provide clean drinking water and save lives.

During our rst visit to Liberia, we saw people drinking out of gutters, salty swamps and shallow holes in their back

yards,” he said. “All the piped water had been cut off due to the civil war.”

Due to this devastation, Gehrels be-gan his initial water program in Libe-ria’s capital Monrovia. Equipped with the Lone Star LS100 drill, Gehrels be-gan drilling wells at major street inter-sections and common market locations to give residents access to safe water. It was this drilling success that sparked Lifewater Canada and would lead to 25 trips to Kenya, Nigeria, Haiti and Libe-ria and more than 700 wells.

“I remember calling Lone Star re-

garding the drill during that rst trip,” Gehrels said. “While on the phone, Lone Star mentioned they shared the story of my journey in Liberia with a foundation. The foundation was so im-pressed that it paid for the drill rig. It was an incredibly moving moment and reaf rmed the work I was doing.”

Gehrels emphasizes that it’s the kind of bond the two companies have shared from the very start and maintained to this day. Designated leaders in Libe-ria, Haiti, Kenya or Nigeria can contact Lone Star at any time, and the company will ship whatever is needed for them to repair a drilling rig and invoice Lifewa-ter Canada. It’s a connection based on trust and common vision.

The right tools Throughout the years, Lifewater

Canada has made a signi cant invest-ment in its partnership with Lone Star Drills. The company currently owns a drill in Kenya, one in Nigeria, two in Haiti and four in Liberia. The drills

Lifewater Canada has brought clean water to thousands using low cost drilling technology

“During our first visit to Liberia, we saw people drinking out of

gutters, salty swamps and shal-low holes in their back yards,”

Jim Gehrels, founder of Lifewater Canada, trains new workers in Liberia how to safely drill water wells. A strong component of Lifewater’s program is local involvement at every level.

Joe Qua Qua, head driller, has nine years of experience operating the LS100 by Lone Star Drills. He and the team are drilling a well for a village near the Bensonville Highway in Liberia.



Training includes classroom and theory on topics such as hydrogeology, business planning, disease transmission and equipment maintenance. Much time is spent one-on-one, providing practical, hands-on experience in the

eld, including hand pump repair drill training, such as when to stop drilling, how to handle unexpected problems, drill bit selection and how to proper-ly manage drilling uid water quality testing careta er and pump repair tech-nician training and community health and hygiene.

In each community that Lifewater anada visits, the company also wor s

with local leaders to develop a water supply agreement. This agreement sets forth a program that addresses local needs and capacity, and designates a well or washroom careta er and a repair technician. For each well project, Life-water also leaves the required tools with the local village chief.

Helping handsAlong with Lifewater’s volunteers

and the local people trained through the water program agreement, sponsors are a huge part of the success and af-fordability of Lifewater anada’s wor . “Without a project sponsor, a well that could cost $3,500 to drill may as well cost millions in grass hut villages where the people are only ma ing a dollar a day,” Gehrels said.

Despite Gehrels’ fading vision, his clarity for Lifewater Canada has

brought clear water to thousands of grateful people.

“On behalf of the elders and people of ar in oma village, there are hardly enough words to express our gratitude for the gift of life that was given to us by your group,” read a letter from the Sar-in oma Well Committee to Lifewater.

“Every time clean water starts to come out of our wells for the rst time is li e a miracle,” Gehrels said. “ ou

see this water turn from mur y brown to crystal clear, and then you see the joy on the people’s faces. People begin dancing and celebrating, and their joy is contagious and a reaf rmation of all the wor that we’re doing.”

Water Treatment

Brantford, Ontario Holmedale water treatment plant (WTP) is located between the Hol-medale Canal and the Grand

River and supplies water to a popula-tion of 90,000. The original plant dates back to the early 1900s. Several up-grades took place over the past century, but none of the components of the old WTP are currently in operation.

The City is now operating a com-pletely new water treatment facility, as a result of the following signi cant upgrades:

1999: Phase 1 - addition of a new low-lift pumping station and prelim-inary treatment facility, featuring the

cti o high-rate clari cation process.2004: Phase 2 - addition of a new

residue management facility, featuring thickening, dewatering and residue dis-posal processes, as well as upgrades to an existing 17 ML reservoir.

2012: Phase - new ltration facili-ty, chemical systems building, chlorine contact tank, administrative building and high-lift pumping station.

Commissioning of the new 100 M/d WTP in May 2012 was the culmination of the City’s decade-long upgrade of the water treatment plant. This brought it up-to-date with current water quality regulations and prepared it for future, stricter regulations.

R.V. Anderson Associates Ltd. was commissioned by the City and complet-ed both Phase 2 and Phase 3 upgrades.

Higher water quality goalsThe Grand River is a challenging

source of raw water, particularly since Brantford is located in its lower water-shed and downstream of many other communities and installations. Histor-ically, the WTP experienced seasonal-ly high ammonia levels, and taste and odour (T&O) complaints. Also, there is a potential for source water contamina-tion from upstream agricultural run-off, wastewater discharges and chemical spills.

Brantford was faced with the dual

challenge of unpredictable raw water quality, and providing safe, aesthetically pleasant drinking water to the popula-tion. In addition, the City was experienc-ing signi cant operational expenditures to deal with emergency situations result-ing from spills and other events.

To help achieve current and future treated water quality goals, a multi-bar-rier approach was selected, including:• Ozone system: a two-unit ozone gen-

erator system, with hydrogen peroxide quenching system and two ozone con-tact tanks with a total capacity of 2,200 m3. The Peroxone system is designed to assist with the biological filtration process, and provide T&O treatment through advanced oxidation.

• Deep-bed biological filters: eight cells (with surface area of 6 m x 13 m) de-signed for a filtration rate of 8 m/h, with one cell out of service.

• Chlorine contact tank (two cells) with total capacity of 5,200 m3, for primary disinfection.

• UV light disinfection reactors (two on duty plus one stand-by) for secondary

disinfection at a dose of 20 mJ/cm2. The design allows for a fourth unit to be installed in the future, as well as the UV units to be replaced with larger ones for future advanced oxidation treatment process implementation, without superstructure or piping mod-ifications.

• Chemical systems (new and upgraded existing), such as hydrogen peroxide, fluoride, activated silica, ammonia.Brantford wanted to achieve the

best water quality, while optimizing the use of automated control and staff operations and maintenance. A SCADA system provides full information and access system to the WTP operators. A pilot plant was constructed to help with nal design, and currently remains in operation to help staff optimize the treatment process.

Water Treatment

to provide the WTP with disinfection credits. Instead, it was sized to be able to treat most operating conditions (not the worst case) with two duty ozone generators. There is ample room to add up to two more units in the future, if needed. Ozone assists with the biolog-ical ltration, T O reduction, reduces the formation of trihalomethanes and haloacetic acids, keeps the bromate for-mation below 10 mg/L, enhances disin-fection (although no disinfection credit is given) and reduces coagulant use.

The lter design allows for slow ltration to assist biological activity. owever, the lters and the entire plant

could produce up to 154 ML/d if they were operated at a ltration rate of ap-pro imately 1 m/h, with one lter out

of service. Hence, the WTP has spare capacity, if required.

igni cant contact time for disin-fection is provided by the ed volume (5,200 m3) two-cell chlorine contact tank (CCT). Conversion to chloramines is done at the end of the CCT, by addi-tion of ammonia. The supplemental UV disinfection system would automatical-ly switch on under speci c conditions (generally winter) when low water tem-perature and pH level reduce the disin-fection ability of chlorine. It can be used during events when higher ammonia levels are present in the source water.

The plant is designed to operate at any range of ow between 35 and 154 ML/d, with no superstructure changes or modi cations. ll emergency and

When septic systems are near fresh water lakes and rivers, ocean reefs, and potable water source protection zones, attenuation of phosphorus (P) is required. Also, receiving

soils must be iron-rich, preferably with high aluminum or calcium contents, to adsorb and mineralize phosphorus.

Reactive dissolved phosphorus passing through iron-rich ‘B-horizon’ soils binds chemically to iron oxides and ultimately forms iron-phosphate minerals. These reactions can be very quick. Because Fe-P minerals have very low solubility constants under both aerobic and anoxic conditions, dissolved phosphorus below septic system leach elds is removed from the hydrologic cycle and kept out of groundwater and adjacent surface water bodies. Two comprehensive reviews of phosphate in groundwater are Robertson et al. 1998 (septic systems) and Domagalski & Johnson 2012 (agriculture).

Where natural iron-rich soils are not available, methods to remove P include aluminum sulphate in the septic tank, or electrolysis of metallic aluminum to form a occulent sludge and physically separate P from the sewage. This will ultimately be treated elsewhere. Sewage can also be passed

through iron-rich slag and other reactive materials to attach permanently as detailed in Hutchinson & Jowett (1997) and Heufelder & Mroczka (2006). However, these methods have not generally proven useful for residential-scale systems.

This article details the results of a new technique, using the Waterloo EC-P ™ (patents pending), that mimics the P-removal ability of natural iron-rich soils. Iron is dissolved directly into the sewage to react with P and be removed as mineral precipitate in subsequent soil leach elds, or other

ltration components. The advantage over natural iron-rich soil is that both P

and Fe have already chemically bonded in ne particulate form, before they enter the soil leach eld. They migrate together to the ltration component and all they need to do is precipitate onto soil or sand surfaces, or onto synthetic

ltration media like foam. The technology is abiotic, thus temperature independent, and is largely independent of water characteristics, with no adverse effect on pH.

The volume of mineral precipitate accumulating in the upper 0.3 – 0.5 m of soil is small, It has been calculated at

continued overleaf...

There is almost universal ac-ceptance in the site assess-ment industry that the cer-ti cate o analysis rom an

accredited laboratory gives an accurate estimation o the concentrations o each parameter in the samples submitted. There are good reasons or this. ll ac-credited labs are regularly checked by an outside agency, which sends out per-ormance testing samples twice year-

ly. It also conducts quality audits on a regular basis to ensure the lab’s quality control system is both written down and being adhered to.

The certi cate o analysis issued by the lab lists the concentration o each parameter, the government’s accept-able limit or that parameter, the e-porting etection imit or the lab method used, and the lab’s in-house quality control results. It also lists the date samples were taken and received, and the date the certi cate was issued. It ags against any anomalies or de-partures rom accepted protocols and provides a host o other in ormation. Even a single sample sent to the lab produces a si -to-eight page certi cate o analysis. o what could be wrong with that n ortunately, lots

Does the sample sent to the lab have the same concentration o contaminants as the area o the site it was taken rom

ne thing is or sure, contaminants in soil are never evenly distributed and every site is di erent. The consultant’s ob is to nd out where they are and

then to remove them. It is how this is currently being done that desperately needs attention.

There are two problems that must be addressed be ore the results received rom the lab can be accepted as reli-

able estimates o the levels in the eld. The sample sent to the lab should be a representative sample o the area being sampled; and the lab should get a rep-resentative sample out o the bottle to run the analyses. ctually, there is an even more undamental problem that

needs to be addressed. Is it possible or lab-sized samples weighing ~100 grams to be representative o many tonnes o soil?

These questions are essentially being ignored and the reason seems tied to the act that either the legislators orgot to

address the problem or it was an in-convenient truth” that had no easy an-swer. ntario’s rown elds egulation 1 0 says that the consultant shall gather representative samples...” but gives no indication how this should be done. dditionally, it says the consul-tant shall set Data Quality Objectives, which outline the overall level o un-certainty that a Quali ed erson will accept in collecting eld data in order to develop a onceptual ite odel.”

gain it gives no instruction as to what is acceptable.

Worse than that, regulations instruct consultants to sample soil piles by tak-ing at least one sample every 50m3 or, i importing ll to a site, at least one sam-ple every 150 m3. That’s one lab sample every 0-100 tonnes o soil or piles and one lab sample or every 50 tonnes o

imported ll. Even i sample numbers are quadrupled, results are still not even in the statistical ballpark.

recent court-case in Ontario illus-trates the problems with this approach.

dig-and-dump site cleanup was un-derway, when the rovincial Environ-mental O cer drove by and noticed a lump o black goo alling into a dump truck rom an e cavator bucket. The in-spector called in, climbed up the truck and grabbed a sample o the goo. res-to nalysis o the goo showed it to be un t or dumping with the rest o the hundreds o tonnes o soil in the local land ll to which it was being hauled. The company was charged and ned 1 5,000

The appeals court re used an appeal because the rown elds egulation does not speci y the size o sample to be taken. This decision should make every consul-tant, contractor and site owner very ner-vous indeed It is also very un air.

liquids, which can be adsorbed and ab-sorbed by the soil. Common examples of solid particulates are from sand-blasting operations, where lead paint is removed from steel equipment and falls onto the soil. Sand-blasting material itself can be a major source of contaminants, since older material was produced from nick-el-re ning slag.

The most common example of liquid contaminants would be from gas sta-tions, where fuel spillage around pump islands or leakage from storage tanks and delivery lines, contaminate the soil. In no case does the contaminant uni-formly distribute itself throughout the soil. Rather, it follows a variety of path-ways of least resistance, depending on the soil types. It is up to the consultant – usually with very limited historical information – to estimate, or guess, how the contaminants are spread across the site, both horizontally and vertically.

There is a gaping chasm in sampling requirements between what is necessary for contaminant distribution and what legislation deems necessary. Sending a

100-150 gram sample from a borehole to the lab for contaminant analysis and

expecting the answer to be an accurate description of what’s in the many tonnes

of soil around the borehole is not just faulty, it is insane.

For example, 5-10 grams from sam-ple bottles are taken for metal analysis, but only 1-1.5 grams of this are actually analyzed after pulverizing. Three-to-four grams are sent in a separate bottle for VOC analysis or for BTEX/F1 anal-ysis, and ~10 grams are taken for PAHs. These sampling and analysis rules fol-low the Regulation’s recommended pro-tocols. However, they are a clear indica-tion of what happens when you choose to ignore the most fundamental rule of soil sampling: “make sure your sample is representative of the whole.” If the sample sent to the lab is not representa-tive of the area from which it was taken, no amount of careful analysis at the lab will produce a meaningful result.

Real-life scenariosBefore being redeveloped as a ware-

house, a former metal fabrication site used sand-blasting and paint-spraying for many years, and is to undergo a Phase 2 environmental site assessment. It is unknown where the blasting sand was dumped, so the consultant drills a number of boreholes and collects sam-ples into laboratory-provided bottles. Screen analysis indicates that the site soil is coarse sand with an average parti-cle size of 1 mm3. Samples are collected into 100 mL soil jars and submitted for

analysis. The lab screens the soil through a 2

mm sieve, discards the +2 mm fraction, then withdraws 5 - 10 grams from the bottle, pulverizing this to pass through a 300 μm (0.3 mm) sieve. Yet, how many soil particles were taken from the sam-ple bottle for pulverizing?

If all the soil particles, including the lead paint particles, are perfect 1 mm cubes, then 1 cm3 of soil, approxi-mately 1.5 grams, contains a maximum of 1000 particles. In reality, due to air-space, there are about half this number or 500 particles. So, if the lab withdraws a 7 gram sub-sample from the bottle for pulverizing to minus 300 μm before withdrawing a cut for analysis, there are 3,500 particles in the sample. Here’s where it gets interesting.

Assume the true lead concentration in this area of the site is 600 mg/Kg (Five times the allowable Ontario limit of 120 mg/Kg).

If just one of the 3,500 particles is lead paint, the lab certi cate will report the lead concentration as 1620 mg/Kg. This is more than 13 times the true val-ue. One cubic-millimeter of lead, one “soil” particle, weighs 11.34 mg. There-fore, 11.34 mg of lead in a 7 gram sam-ple represents a concentration of 1620 mg/Kg of lead. If two particles of lead are present, the lab will report 3240 mg/Kg and if no lead particles are present,

the lab will report a “non-detect.” How-ever the true value for the area is 600 mg/Kg!

A 7 gram sub-sample can be pulver-ized to the consistency of ne our, but it won’t correct seriously wrong results. Furthermore, it is impossible for any 7 gram sample to give you a correct re-sult because the sample is too small to be able to produce the correct answer!

In order to have a hope of getting the correct answer, the sample size analyzed would have to be at least 18.9 grams, with only one lead particle in the sam-ple (11.34 mg lead in 18.9 g of sample = 600 mg/Kg). For the lab analysis to indicate something close to a correct re-sult, the sample size should be 50 - 100 grams and all of it should be analyzed for lead. The problem is, of course, that labs cannot handle anywhere close to these sample sizes. So many consultants are left scratching their heads when du-plicate samples from the same location produce widely different results.

What needs to be done?The lead limit in soil is 120 mg/Kg.

For cadmium in a potable groundwater

site it is 1.9 mg/Kg and for benzene it

is 0.32 mg/Kg. Trying to get meaning-

ful results at these levels from small soil

samples is futile. The analysis results of-

ten disagree by well over 100 per cent as

shown in the examples of site cleanups,

where duplicate soil samples were taken

for analysis. Table 1 shows PAH results

Combustible dust explosions in two British Columbia saw-mills in the winter of 2012 led to WorkSafeBC, the B.C.

Safety Authority, and Fire Marshall re-quiring and enforcing compliance with regulatory requirements. Owners, engi-neers, contractors, and suppliers associ-ated with facilities that have combusti-ble dust hazards will need to follow the WorkSafeBC directives.

While there are many wood dust and wood working facilities in British Co-lumbia, WorkSafeBC requirements are for “combustible dusts.” This includes agriculture products, chemical dusts, metal dusts, plastic dusts and carbona-ceous (coal, peat and cellulose) dust.

This article outlines requirements as they relate to heating, ventilation and dust collection systems. Combustible dusts are de ned by the ational Fire revention Association ( F A) as, “a nely divided combustible particulate solid that presents a ash re hazard or explosion hazard

when suspended in air.”A de agration (a subsonic explosion)

hazard exists when there is an approxi-mately 3 mm layer of dust on horizontal surfaces, or suspended in air at a concen-

tration in excess of 40g/m3.In most industrial facilities with com-

bustible dusts, mechanical dust collec-tion systems are installed to capture and reduce the accumulation of dust to avoid

Alberta’s oil sands producers have become a major driver of Canada’s economy. How-ever with nancial rewards

have come environmental costs associat-ed with production. These can generally be divided into two categories: air pol-lution, and water or tailings ponds con-tamination.

It currently takes over three barrels of water to produce one barrel of crude oil. According to the Canadian Association of Petroleum Producers, current oil sands fresh water usage is approximately 170 million cubic meters per year. This is just over 43 per cent of the City of Toronto’s consumption in 2010. Since our water re-sources are limited and shrinking, recy-cling is necessary. This is precisely what tailings ponds are designed for – to act as recycling deposits for water reuse in the primary stages of bitumen separation.

The oil sands process is simple in concept. Bitumen is washed from the sand using hot water and solvents. It then

oats to the surface, where it is skimmed off for further re ning.

This process produces tailings water that contains residual oil, heavy metals, sand, solvents and very ne particles of clays called nes. Tailings water is sent to a pond where it is reused in the pri-mary extraction phase, thus reducing the volume of fresh water needed.

However in the tailings ponds, water is contaminated with residual oil, and remaining toxic solvents accumulate through continuous recycling. Heavy metals also accumulate during recycling, and the low suspended gravity of nes keep them suspended in water, some-times for years.

Federal and provincial governments, as well as oil sands producers, recognize the environmental repercussions. The Alberta Government, through the En-ergy Resources Conservation Board or Alberta Energy Regulator, issued Direc-tive 074 in 2009, which set out emission compliance regulations for oil sands pro-ducers. In 2013, it reported that, “com-

panies failed to comply with pre-existing agreements to limit the amount of water used in tar sands extraction and process-ing, as well as the amount of polluted water that ends up in the region’s grow-ing toxic tailings ponds.”

That is not to say that the companies have not been working towards solving the emissions problems. In fact, Suncor has spent over $1.3 billion on its TRO™ tailing management process. This pro-cess captures nes and many of the other contaminants through occulation. Floc cake is then dried and used as land ll in

the mined areas, which are then fertil-ized, seeded, treed and returned to forest.

In 2012, fourteen oil sands produc-ers formed the Canada’s Oil Sands Innovation Alliance, in order to col-laboratively explore and implement in-novative concepts to solve the tailings pond problem. The alliance has identi-

ed tailings ponds as their environmen-tal priority area.

In Northern Alberta alone, there are over 176 km2 of tailings ponds, contain-ing an estimated 187 billion gallons of liquid. The Pembina Institute estimates the cost of cleaning them, at $8 to $10 billon. Everyday, producers increase the contents of these ponds by 52,630,000 gallons and expect production to increase over 40 per cent in the next 20 years.

This massive problem is being ad-dressed by the producers and they formed the Canadian Association of Petroleum Producers (CAPP) to supply information to the public. In November 2013, CAPP published the 2013 Responsible Cana-

3 Fs approach helps solve Alberta’s tailings pond problems By Jack Schneider, Sr.

dian Energy Report. The report details industry performance in key areas such as the environmental priority area and is intended to promote and enable industry performance over time.

Hydro Processing‘s technologies have applications in a variety of industries, but the most compelling area is tailings pond remediation. The “3 Fs” approach to the problem ill be a signi cant fac-

tor in cleaning up existing ponds and “clean as you go” methodologies going forward. Patented technologies for Flo-tation, Flocculation and the building of a Froth Cap, require low cost energy inputs, have no moving parts, are easily retro tted, and cost-effective.

Hydro Processing’s Flotation reactor has proven capabilities in separating ex-tremely low amounts of oil from water. These reactors can be installed to cap-ture residual oil in water destined for tailings ponds. The nano and micro-size bubble reactor is able to capture nely dispersed oils and oat them in a tank for skimming, or into a boomed pond area for further collection. This will re-duce the oil in the pond and increase the plant’s primary recovery.

Similar reactors will be used to dis-tribute Flocculant in order to capture and retain nes and sand. Hydro Pro-cessing’s reactors have proven extreme-ly ef cient in the distribution of occu-lants, due to the nature of the centrifugal forces residing within the chamber. As a result, distribution becomes almost in-

Setting the Standard in Quality

Fuel oil product in a sump pit is a unique situation. The remediation approach that will be needed to restore the environment back to normal will also have to be unique.

Finding the source of the contamination and completing the remediation of impacted soil and water will require the combined knowledge of an experienced team of environmental professionals with knowledge of the most up-to-date regulatory requirements.

Rochon Environmental determines the source of the environmental contamination so that the best remediation approach can be implemented without recourse.

Getting the environmental remediation done right the first time minimizes liability, helps restore the environment and gets our clients’ lives back to normal.

Emergency response: Available 24 hours a day, seven days a week.

Once the pollutant is consumed, the bacteria die, as there is no more food for them to subsist on. The pond is then able to find its own natural environmental balance.

A toilet fueled by the sun is be-ing developed to help some of the 2.5 billion people around the world lacking safe and

sustainable sanitation. It was unveiled in India recently. The self-contained, wa-terless toilet, designed and built using a $777,000 grant from the Bill & Melinda Gates Foundation, has the capability of heating human waste to a high enough temperature to sterilize it and create bio-char, a highly porous charcoal.

According to project principal inves-tigator, Karl Linden of the University of Colorado Boulder, the biochar can be used to both increase crop yields and sequester carbon dioxide, a greenhouse gas.

The project is part of the Gates Foun-dation’s “Reinvent the Toilet Challenge,” an effort to develop a next-generation toilet that can be used to disinfect liquid and solid waste, while generating useful end products, both in developing and de-veloped nations.

The awards recognize researchers who are developing ways to manage

human waste that will help improve the health and lives of people around the

world. Unsafe methods to capture and treat human waste result in serious health problems and death. Food and water tainted with pathogens from fecal matter cause the deaths of roughly 700,000 chil-dren each year.

Linden’s team is one of 16 around the world funded by the “Reinvent the Toi-let Challenge” since 2011. All shipped their inventions to Delhi, where they were on display for scientists, engineers and dignitaries.

The CU-Boulder invention consists of eight parabolic mirrors that focus concentrated sunlight to a spot no larger than a postage stamp on a quartz-glass rod connected to eight bundles of -ber-optic cables. Each of these consists of thousands of intertwined, fused bers. Energy generated by the sun and trans-ferred to the ber-optic cable system can heat the reaction chamber to over 315 degrees Celsius, to treat the waste ma-terial, disinfect pathogens in both feces and urine and produce biochar.

Biochar can be used in agricultur-al areas to hold in nutrients and bring more stability to the soils. According to

Linden, a soil mixture containing 10 per cent biochar can hold up to 50 per cent more water and increase the availabili-ty of plant nutrients. It can also be used as fuel, providing energy comparable to that of commercial charcoal.

Linden says that, while the idea of concentrating solar energy is not new, transmitting it exibly to a customiz-

able location via ber-optic cables is the really unique aspect of this project. Tests have shown that each of the eight

ber-optic cables can produce between 80 and 90 watts of energy, meaning the whole system can deliver up to 700 watts of energy into the reaction chamber.

In late December, tests at CU-Boulder showed the solar energy directed into the

reaction chamber could easily boil water and effectively carbonize solid waste. The current toilet has been created to serve four to six people a day. However, a larger facility that could serve several households simultaneously is under de-sign, with the target of meeting a cost level of ve cents a day per user set by the Gates Foundation.

The CU-Boulder team is now apply-ing for phase two of the Gates Founda-tion grant to develop a eld-worthy sys-tem to deploy in a developing country based on their current design. They will also assess other technologies that may enhance the toilet system, including the use of high-temperature uids that can collect, retain and deliver heat.

Other institutional winners of the grants range from Caltech to Delft University of Technology in the Neth-erlands and the National University of Singapore.

The most common way to introduce the air to the DAF unit is via a recycle pump system. A fraction of the treated water leaving the unit is recirculated to the inlet. Within this loop air is intro-

duced to create micro-sized air bubbles.Older DAF systems had a big satu-

ration tank, where pressurized air was introduced and mixed with the recycle pump ow. odern systems use multi-stage centrifugal pumps, that are able to tolerate a certain amount of air owing right through their impellers and cham-bers. This eliminates the need for a big, pressure-rated saturation tank. Air is usually injected right at the pump, and it does most of the air/water mixing.

The recirculation pump pressurises water to approximately 6 bar and sat-urates it with a controlled amount of air. Saturated recirculation water is col-lected in a recirculation tank and dis-tributed at points underneath the DAF unit. Small air bubbles are formed by means of sudden depressurisation of the recirculation water with ball valves. The small size of the air bubbles (30-0 micron is essential for the ef cien-

cy of the otation unit. This air is what

Wastewater

A typical anaerobic digester in a municipal wastewater facility processes human waste, FOG (fat, oil, and

grease), and other organic material, and heats this sludge to about 38°C. The heated sludge creates biogas, a methane gas mixture (CH4-CO2) containing a signi cant amount of water apor. aily and seasonal temperature ariations can affect the density of the water apor.

arm temperatures cause ery small water particles, while cool temperatures create large ones with increased water entrainment in the pipe.

eliable ow measurement is the leading indicator of digester operation and health. Historically, wastewater fa-cilities ha e ignored digester data, be-cause the information was unreliable.

ow that ow meter manufacturers are focusing on the unique requirements of the wet gas en ironment, plant opera-tors can learn to trust ow meter data. They can then use digester production information to a oid upsets and ta e pre-empti e correcti e action.

Measuring biogas in digesters and other wet gas applications

Typically, wet gas measuring appli-cations remo e water and then use any

ow meter that can measure a dry ow or elocity. Two common methods ha e been employed to alle iate the issue of condensation affecting ow meter per-formance:1. Mechanical refrigeration systems/

desiccant dehumidi er systems, wor by remo ing moisture through absorption or adsorption. They typi-cally ha e a high initial cost, a mod-erate-to-high maintenance cost and operational energy costs.

2. The heat tracing method raises the process ow temperature by warm-ing biogas pipes. This eeps the wa-ter apor in smaller particles, while lowering the CH4-CO2 concentra-tion. hen installed in a Class , i-ision or 2 area, these systems ha e

an o erall high cost, e en though the initial cost and maintenance/opera-

tion costs can appear moderate. For example, a modest three digester system would consume o er 2, annually in energy costs. Based on

. / h for a cm pipe with cm of insulation co ering 4 m, rais-ing the pipe temperature ° would require of heat.

hen considering any ow meter-ing technology, additional requirements beyond the initial de ice should be in-cluded as part of the o erall cost of the de ice. Biogas applications typically in-

ol e low elocities, which is one of the ma or criteria in selecting a ow moni-toring technology.

Ultrasonic meters are an option, but their typically high purchase price has essentially bloc ed them from the mar-et. n addition, they require bypass

plumbing and periodic tear-downs for cleaning. hile ultrasonic de ices in-trinsically measure actual ow or e-locity, they must be pressure and tem-perature corrected for mass ow, which is the required measurement to meet regulations.

Thermal ow meters are frequently used because of their ease-of-installa-tion and low ow capabilities. Howe er,

they are sensiti e to moisture in the ow stream, and additional processes must be used to control condensation. n consid-ering product life cycle and functionality issues, insertion thermal meters are gen-erally the technology of choice.

The Nature of Biogasn consistently warm temperatures,

water particle si e is less than 2 mi-crons. ater-saturated biogas has a mbar partial pressure that represents . per cent water in the methane mix at sea le el air pressure ( mbar). ater apor fogging density, or liquid water

content (LWC) in g/m3, is proportional to the cooling rate in a pipe. The heat used in a thermal sensor is typically enough to apori e the particle.

When the biogas pipe coming from the digester cools to less than 21°C, saturated water partial pressure drops to 2 mbar, or 2. per cent water apor. As the pipe cools, particles con erge and get larger (with many of these contacting the ther-mal sensors). en more particles con-tribute to the liquid ow along the bottom of the pipe. The increased fog that forms in cooling biogas piping is the root cause for false high ow measurements with

It is important to note that the heated sensor is well below the 537°C auto-ignition point for methane gas. Liquid impacting the hot sensor is immediately vaporized to steam. The power required to vaporize the water at a given ow rate is de ned by the LWC, gas velocity, and sensor effective area.

Figure 2 compares three different thermal meters installed on a digester, where red is the biogas temperature, blac is the dry ow, blue is the Kurz WGF, purple is the Kurz standard me-ter, and orange is a popular thermal competitor. During the warmest part of the day, all the wet gas meters converge and are reading about six per cent high compared to the treated dry ow meter. During cooler periods, the readings sep-arate out and start over-reporting at var-ious levels. Separation is related to the LWC condensation density in the pipe, which is highest at lower temperatures.

Conclusioneliable and accurate ow meters

Plant operators can adjust sludge and

FOG dosing to achieve more consistent gas production, alter biogas production to maximize electrical savings based on daily utility rates change, and minimize gas aring. With cost-effective, reliable wet gas ow measurements, they can be ready to accurately report biogas sourc-

Wastewater Pumping

Every day, one third of lift sta-tions have intermittent and ab-normal occurrences. These in-clude bouncing starters, faulty

check valves, low pumping capacity at a critical time, unreliable level sensors or badly programmed PLCs. Would you prefer to know when a problem is intermittent, or when the station isn’t operating anymore? This article will explain how easy it can be to analyze every aspect of the most popular type of lift station.

The USEPA wrote in their Collection Systems Technology Fact Sheet – Sewer Lift Stations that “power costs account for 85% to 95% of total operational and maintenance cost”. Very few munici-palities use this valuable information to evaluate the pumps at their lift stations. With the right tool, getting the appropri-ate data is simple, inexpensive and can be done in-house. Analyzing the data is where you should spend your money, if you don’t understand how a lift station is supposed to run.

Most of what is wrong within a pump station affects the pumps! Since the most expensive element is the cost of the elec-tricity running them, it makes sense to use the current used by the pumps as the primary way to monitor them.

If the current from each leg is not properly balanced, then the pump will wear faster, and use more electricity at a higher temperature to deliver less capacity. If the current is substantially lower or higher on the same leg for all the pumps, then the voltage supplied to all the pumps is probably the cause. Current tells when the pumps start and stop, and, therefore, their run times and number of starts. The volume between the start and stop level allows calcula-

If the remote terminal unit (RTU) isn’t properly programmed, if the pumps do not alternate properly, or if starters are chattering, the pumps will be affected, and this will be recorded through the current sensors.

Power consumption per pump can be

calculated using a voltage sensor or en-

of the pumps and duration of operation, the volume pumped can be determined. When you divide this by the power con-

is the number of liters pumped per watt of electricity.

Four main elements are needed to properly analyze a lift station: electrical current recorder and sensors, smart soft-ware, a means to calculate the volume of the wet well, and some basic knowledge and experience with lift stations.

The electrical recorder must be small

panel. Battery operation is required, where AC is not available. Memory ca-pacity of the recorder should be for a minimum of one week, but preferably one month, with a sampling rate of one second.

The sequence of operation of the pumps is one of the most useful pieces of information for lift station diagnostics.

Setting up the monitoring system in-volves the following steps:

1. Install the recording hardware. Measuring phase current is best. Voltage only provides information about the qual-

ity of the electricity supplied. It is fairly inexpensive to install current sensors per-manently at each lift station.

2. Measure the well. The information required is the volume between the oper-ation levels (high and low) of the pumps. If the station uses floats, they should be clean.

Volumetric formulas are used to cal-

between the high and low levels must be entered as a constant. The average pump run time per cycle is directly affected by the distance between the levels.

Measuring high and low levels in the wet well takes more time than installing or removing the rest of the hardware. It is critical to the analysis and must be done

analyzed periodically, then measuring the levels should only be done if the re-sults are different than expected. A con-

should stay relatively constant. If you see a variation on all the pumps by the same percentage occurring at the same time, it is a sign that the levels have to be mea-sured again and proper data re-entered in the calculation software.

3. Recording. After three cycles, you already have enough data to generate a report, but this is not enough to know if the lift station is operating properly. A minimum of two days or more is re-quired to make a decent analysis. A week is even better, especially if you can cap-ture a rain event.

4. Download the data. Downloading via cellular modem is simple and fast and allows remote monitoring of the lift sta-tion. If you have a SCADA system, it is very useful to see the time difference be-tween what is reported by the recorder in real time, and what the SCADA system is displaying.

5. Data analysis. This is where knowledge and experience become price-less. If you use Excel to analyze the data, use one line per event. This format is the easiest to understand.

Many diagnostics can be done with these tables, but it is your knowledge and

experience regarding lift stations that ill help o g re o t hat is rong

When you see that two pumps are al-ways starting and stopping at the roughly the same time (within a few seconds), it often indicates a problem with level switches When you see the capacity of a pump and its phase current dropping, it can be related to the impeller, an obstruc-tion at the pump inlet or the check valve of the other pump

This is the easiest and fastest way to as-sess the operation of a pump station and the safety margin of the pumps’ capacity during normal ow in the station

When the height of the bars is not sta-ble, then the station is probably pumping into a force main t is especially import-ant to look at the pump capacity during rain events because their capacity is usu-ally lower, while the in ow is higher Therefore, the safety margin is smaller then expected

Ultimately, the pump station analysis system that you will use should provide you with a summary report similar to Table 1 and calculate the annual energy savings that would be obtained by using

the pumps at their maximum ef ciency (ef ciency of the best pump)

Tuning pump station performance is not only about measuring ow ccu-rate operational data can provide key information for I & I studies, and hy-draulic modeling, as well as lift-station ef ciencies

Water System Pumping

A high lift pump station at one water supply plant has four constant speed pumps. Two pumps have a rated capacity of 900L/s @ 85m total dynamic head (TDH) and two a rated capacity of 350L/s @

82m total dynamic head. In order to maintain serviceability, the distribution system must maintain an operating pressure of 70m TDH.

At present, both the large and small high lift pumps are operating with a higher pumping capacity to match the sys-tem head curve as well as the required operating pressure. In order to maintain the required system pressure and satisfy the required ow condition, the e isting pumps need to be controlled by throttling the discharge valves. This results in wasted energy consumption.

Throttling the valve at the pump discharge introduces ad-ditional head loss to the system. This elevates the system head curve above the required operating pressure and at the point of intersection of the pump curve and demand line. The dis-tribution system is thus supplied with increased head or pres-sure, but the pump is operated at a lower ef ciency rate. rom an energy ef ciency standpoint, additional head loss reduces the amount of water being pumped but increases total energy consumption and costs.

ystem head- ow curve and pro ected design years de-mand are shown in igure .

The system head curve is represented by the total dynamic head versus ow for all ow rates within the pro ected design year. Total dynamic head is made up of two components; stat-ic head and dynamic head losses.

The high lift pumps draw water from the clearwell, dis-charge to the distribution system and ll the elevated reser-voir.

Static head is equal to the vertical lift between the clear-well and reservoir. Dynamic head losses are the friction losses through the watermains from the plant to the elevated reser-voir and high lift pump discharge piping and ttings. Dynam-

ic losses can be determined for the pro ected year ows using distribution model analysis.

Design Alternativesour alternative scenarios were evaluated, in order to de-

termine feasible electricity optimization solutions for the pro-ected design years. The methodology employed in the evalu-

ation of the alternatives included:• Generate the combination of pump curves that will meet the

demands of the system head curves, minimum operating pres-sure for each alternative, and for each pro ected demand de-sign year scenario.

• Demonstrate the hydraulic performance for each operation and determine the alternative that would minimize energy use.

• Perform present value of power cost analysis and maintenance of variable frequency drives for pro ected design years and capital cost estimate for each of the alternatives.

Alternative oneIncorporate two small or mid-range pumps operating in

parallel to meet 5yr. demand, one large pump to meet 0yr. demand, one small pump and one large pump operating in parallel to meet 5yr. demand and two small pumps and one large pump operating in parallel to meet 25yr. demand. The system operating curves simulated with pro ected design years are shown in igure 2.

The calculated cost of e cess power consumption with Al-ternative , due to throttling for different pro ected demand years, is shown in Table .

Energy optimization designs evaluated for high lift pumping stations By Jahangir Chowdhury

35-Energy Effic Pump Design.indd 50 3/27/14 1:03 AM



Alternative twoIncorporate one large pump to meet 5yr. demand, one large

pump to meet 10yr. demand, two large pumps operating in parallel to meet 15yr. demand and two large pumps operating in parallel to meet 25yr. demand. The system operating curves simulated with projected design years are shown in Figure 3.

The calculated cost of excess power consumption with Al-ternative 2, due to throttling for different projected demand years, is shown in Table 2.

Alternative threeThis alternative incorporates the same number of pumps

in operation for different demand years as in Alternative 1, with additional VFD units to each pump. No throttling to the discharge valve is required and, therefore, there is no excess power cost. The system operating curves simulated with pro-jected design years are shown in Figure 4.

Alternative fourThis alternative incorporates the same number of pumps

in operation for different demand years as in Alternative 2, with additional VFD units to each pump. No throttling to the

discharge valve is required and, therefore, there is no excess power cost. The system operating curves simulated with pro-jected design years are shown in Figure 5.

Present value costsThe calculation of present value cost of each of the alter-

natives depends on the assumptions made regarding the cost of additional power, as well as those costs not common to all alternatives. Life cycle costs common to all alternatives are not presented in this analysis. In determining power costs over the projected life cycle period, it assumed an increase for power at 5% per year and an annual interest rate of 4% per year.

Table 3 summarizes the present value of power cost analy-sis and maintenance of VFD units for 5 yr. projected demand. It also summarizes capital cost estimates for pumps and VFD units for each of the alternatives. Similar analysis was carried out for 10yr., 15 yr., and 25yr. projected demand and the re-sults are presented in Figure 6.

Conclusion Alternative 1, which consists of a combination of small

or mid-range and large pumps is a less expensive alternative up to the 15 year design period. However, it becomes a more expensive alternative by the end of the 25 year design period.

Alternative 2, which uses large pumps, requires the least initial investment, but becomes the most costly alternative over the entire design period.

Alternative 3, which adds VFD units to the pumps used in Alternative 1, is an expensive alternative over the entire

design period and an unacceptable alternative. Alternative 4 which adds VFD units to the pumps used

in Alternative 2 is more expensive up to the 10 year design period but is the least expensive in the long run. Therefore, Alternative 4 can be seen to be the most desirable alternative in terms of cost and energy optimization.

tance from water body (36.5m to 5000 m), change was observed for toluene, ethylbenzene, xylene and PHC F1 only. All other petroleum related parame-ters did not change from the applicable SCS.

When generating PSS for ground

water, change was observed for BTEX, PHC F1 and Pb, when adjusting the depth of the water table. With respect to hydraulic conductivity values, only toluene, ethylbenzene, xylenes, and PHC F1 changed. For distance from water body, only toluene, ethylbenzene,

xylenes, PHC F1 and Pb changed. The parameters PHC F2 to F4 remained un-changed from the SCS throughout the sensitivity study.

In addition, the sensitivity analysis looked at changing fraction of organic carbon (FOC) values at the water table to soil source and upper 0.5 m. During the analysis, no change was observed in ground water PSS for all petroleum related parameters from the SCS. There were changes observed in soil PSS when changing FOC values. In some in-stances, more stringent PSS compared to SCS were generated.

Implementation of RMM can pro-vide PSS greater than the SCS values. The Modi ed Ecological Protection (MEP) measure changes the compo-nent values for mammals and birds by 1000 and plant and soil invertebrates by 1.9.

Energy from Waste

Biogas is a ‘good news’ sus-tainability story for farmers, municipalities, food proces-sors and for quality of life and

the environment. Biogas is a renewable energy technology that is on the verge of major growth in North America. It can be a source of technology transfer, job creation and rural economic devel-opment.

he reliability, e ibility, economic and environmental attributes of biogas should be recognized and supported through a suite of strong policies in all Canadian provinces. Biogas creates re-liable energy regardless of the weather - in the form of heat, power, and pipeline quality gas that can be used for trans-portation (i.e., natural gas fueled vehi-cles), household heating, or industrial, commercial and institutional processes.

Biogas is distinct from other non-hy-dro based renewable energy sources. It can reliably produce power during times of system peak demand, and can be stored during periods of e cess pow-er or surplus base load generation by electricity systems. In addition, biogas systems located on rural electricity dis-tribution systems utilizing synchronous generators have demonstrated positive impacts. They provide stable voltage support in areas of voltage lag, thus im-proving power quality.

ther bene ts of biogas generated electricity include controlled power factor, reduced line losses, improved voltage control on rural feeders, and increasing service stability of electrical

supply to local homes and businessesDestruction of harmful pathogens

and methane, reduction of odours, rural grid support through voltage regulation, and the provision of reactive power, are e amples of biogas bene ts. In addition, it can be used in a combined heat and power (C ) con guration, as well as injected into the natural gas distribution network to offset the use of fossil fuels.

In May, 2013, the Biogas Association contracted with Kelleher Environmental to carry out a Canadian Biogas Study to identify e isting, available metrics which support the bene ts of biogas energy. The potential for biogas produc-tion from agricultural digesters, land ll gas, digestion of source separated or-ganics from residential and commercial sources, and from wastewater treatment plants across Canada, was estimated, as well as the energy, environmental, eco-nomic and social community bene ts of increasing biogas energy production.

Biogas can be converted to biometh-

ane (also called renewable natural gas - RNG), a growing commodity in Europe, the US and Canada. It has the potential to reduce greenhouse gas (GHG) emis-sions from transportation, and provides a range of additional bene ts.

The energy potential of the ve sources of biogas energy evaluat-ed in the Biogas Study is estimated at 810MW or 2,420 Mm3/year of RNG for all of Canada. The relative contribution of biogas to the total estimated energy generation potential value from the ve

Study identifies significant benefits to biogas development in Canada By Maria Kelleher

major sources addressed in the study is presented in Table 1 and Figure 1.

Realizing the full potential of biogas development would lead to development of up to 1,800 separate construction pro-jects, with an estimated capital investment of $7 billion and an estimated economic spin-off of up to $21 billion to the Canadian economy. These construction projects could create 16,800 construction jobs for a period of one year and up to 2,700 on-going long-term operational jobs. In addition, over 100 new and expanded companies, including biogas system designers and developers, equipment suppliers, laboratories, etc., could be supported through an expanded biogas sector.

This gure does not include the many construction com-panies, building supply companies, mechanical and electrical contractors and suppliers who would bene t from biogas pro-ject development.

The number of estimated jobs and investment involved with development of biogas projects in each of the ve sec-tors included in the Canadian Biogas Study are summarized in Table 2.

Barriers to biogas project development in CanadaThere are a number of barriers to realizing the full poten-

tial of biogas energy. Some are common to all biogas projects and some are unique to speci c waste streams.

Financing of projects is challenging due to a reported lack of familiarity with the technology by nancial institutions. Many more full scale facilities need to be constructed in Can-ada to address this barrier. Financial institutions need to be able to “kick the tires” of existing facilities to have a comfort level that their investment is secure.

Wastewater treatment plant biogas projects are sometimes not developed to their full potential as energy generation is not seen as the “core business” of plant operating staff. When budgets are set, other capital projects generally receive more attention than biogas recovery projects.

Receiving approvals for interconnections with the electric-ity system are slow and expensive. Some plants simply waste energy rather than trying to sell it into the electricity grid.

Except for Ontario, feed in tariffs or revenues available for electricity from biogas facilities are not at a level which makes most biogas projects related to electricity generation economically viable.

Biogas projects related to processing of source separated organics need to compete with composting which is generally less expensive. However,the price gap between the two tech-nologies narrows at capacities of more than 60,000 tonnes/

year. This is the amount typically produced by a Green Bin program in a city of 300,000 households, or a population of 1 million. Also, low prices of natural gas present challenges for the RNG industry.

Finally, policies in provinces and municipalities across Canada are not suf ciently supportive of biogas projects. This could be changed through procurement speci cations which require RNG fuelled trucks or other requirements to support production of more renewable natural gas.

The study concluded that development of biogas projects in Canada has potential to create signi cant bene ts, including GHG reduction, as well as creating a stable, reliable, dispatch-able energy source which can be used locally.

Chemistry

During site assessment and reclamation, chemical an-alysis is relied upon to quantify contaminant con-

centrations. This information is crucial for comparison with guideline values, establishing remedial action plans, as-sessing risk, and verifying that remedial targets have been met.

When dealing with relatively un–complicated sites with known sources and clearly identi ed contaminants, this use of data can be suf cient. owever, it shows its limitations on complicated sites involving multiple contaminants of unknown age and origin. Also it de-creases in usefulness with every variable encountered.

By using forensic chemistry, it is pos-sible to simplify complicated sites by revealing the history, origin and nature of contamination. Some examples of the details which forensic chemistry can provide include, but are not limited to:• Characterization of unknown contam-

inants.• Identification of secondary sources.• Separation of contamination from

multiple sources.• Delineation of plumes within plumes

from multiple release events.• Establishing timelines of contaminant

release and migration.• Age dating of weathered hydrocar-

bons.All of this data allows for a better

understanding of a site, prior to deter-mining a remediation or risk manage-ment strategy.

Techniques of forensic chemistryThe forensic process is an integration

of site assessment, laboratory analysis and data interpretation, and is different for each scenario. A diverse toolkit is available, from modeling software to analytical methods. The key to the ef-fective use of forensic techniques is the selection of the appropriate combination for each site and chemical of concern.

The strength of forensic interpreta-tion relies on the method established ear-ly on in the assessment process. These

include long-run GC-FID analysis to resolve hydrocarbon peaks, comparing biomarkers in fuel oil, comparing the ratios of chlorinated volatile chemicals, or contrasting chromatogram curves. In-dividually, data from each analysis does not provide enough information to make conclusions. Therefore, forensic meth-ods must rely on multi-faceted approach-es to evaluate speci c data.

An example of a common use of for-ensic chemistry is to separate fuel oil losses of different ages. Analytical data for this type of process might include concentrations of biomarker chemicals, ratios of hydrocarbon fractions, presence or absence of volatile species and also reviewing the chromatograms for gross differences.

Site conditions, activities on and off the property, depth of contamination and groundwater ow, all are very important. Differences in conditions throughout a property can lead to vast differences in the degrees of weathering of organic contaminants, or ushing and mobiliz-ation of soluble chemicals. Therefore, details of the site conditions at each sam-pling point must be considered, during a forensic review of analytical results.

length ratios; mass fractions of BTEX components, and the identified species; the concentrations of the biomarkers pritstane and phytane in comparison with their uncomplicated analogues; and a model of hydrocarbon concentra-tions and elevations.

The benefit of this method was that, with the exception of the long-run test to quantify the biomarkers, all of the ne-cessary data had been provided with the standard GC-FID analyses conducted during remediation and delineation.

In coordination with the lab, the chro-matogram for each hydrocarbon analy-sis was provided. A review of these was conducted, irrespective of the samples’ location. The conclusion was that four different types of hydrocarbons were present throughout the site.

Each sample result had been re-ported as concentrations of each hydro-carbon fraction. These fractions were converted to a percentage of the TPH concentration for every sample. These ratios could then be compared to liter-ature values for fuel oils, as well as to

each other. By separating the samples into groups with similar ratios, it could be seen that there were three different iterations of weathered fuel oil located throughout the property.

To measure a degree of weathering, the ratios of C17/pristane and C18/phy-tane were evaluated for select samples. As these biomarkers are resilient to nat-ural attenuation, it was anticipated that samples with a low ratio would be older than those with a large ratio. A result of the review indicated that the hydro-carbons which appeared weathered had extremely small ratios. Those near the source had ratios approaching 1. BTEX components were only encountered in less weathered samples.

Finally, all of the analytical data, along with sample elevations, were plot-ted in a three dimensional model. It cal-culated the anticipated hydrocarbons in the space between the sampling points. When this model was overlain on a dia-gram of the site, three fuel oil sources were clearly visible. One was at the fuel oil tank which leaked. Another one was

underneath the furnace. The third one originated from beneath the shared wall with an up-gradient neighbour.

At the conclusion of the project, the use of forensic chemistry, along with conventional site assessment tech-niques, provided sufficient detail to split the responsibility of the remedi-ation amongst the different parties. This saved the client money and permitted closure with the regulatory agency.

ConclusionWhen assessing contaminated sites,

forensic chemistry can be an invalu-able tool. By approaching every project with the anticipation of unforeseen con-taminants of concern, there have been countless times where the use of these tools has permitted cost savings, reduc-tion of liability or superior characteriz-ation of a site.

Water Treatment

• Effluent quality monitoring to ensureproper operation and thallium removalprior to groundwater discharge.• Placement of water treatment residuals(spent zeolites and suspended solids) in ahigh-capacity lined pond.

Inflow rate to the storage ponds willvary seasonally. Total average annual flow

is expected to be approximately 16 m3/hr.The typical treatment flow rate will be 18m3/hr, which will partially fluidize zeolitesin the columns, but still provide adequatecontact time. If inflow rates do not provideenough water to meet minimum treatmentsystem flows, treatment will be temporar-ily suspended until water is available.

Initial influent water quality will besimilar to the range of concentrations pre-dicted by the mixing model. Influent con-centrations will decrease over time due toimproving mine water quality.

Pilot testing and previous full-scale op-erations have shown that zeolites will ad-sorb more thallium when exposed tohigher concentrations, as is typical withadsorbents. To maximize thallium load-ing, zeolite in each column will be trans-ferred backward (upstream) periodically,with fresh material being loaded into Col-umn 5 (the effluent or downstream end ofthe system), and material from Column 1(the beginning or influent end of the sys-tem) being discarded.

It is anticipated that zeolite will betransferred by slurrying it with treatedwater, and pumping it from one columnto another. Influent concentrations may bemanaged by adjusting source flows to in-crease removal efficiency.

Project Management

Engineers, technicians, and de-signers have always had to travel to where their projects are located. Whether it is a

major construction project, or a collab-oration on a wastewater system, design engineers may spend anywhere from a few days to months at a time away from their normal of ces. ome consulting engineers spend virtually all of their time traveling from one project to the next.

The computing power a mobile engi-neer needs has been dif cult to come by. Today, some high-end laptops can make acceptable engineering workstations. Many of these Mobile Workstations or Mobile upercomputers give users the requisite power and computational ca-pabilities they need to complete their projects and assignments, gather data,

process data and manipulate complex models. The problem with many of

these workstations is that they can be rather large, heavy and cumbersome.

There are several ways of supple-menting a laptop for engineers who trav-el, but need more horsepower for their work. One is cloud computing, which allows the client to control processing that is done on a remote server or serv-er cluster, accessible through the Web. A second option is to take advantage of local computing power, by joining the network at the current work location. Then, the engineer can connect to the

home of ce network via the nternet. However, connecting to the local

network, if there is one available, opens the door to security issues on both sides of the connection. For the engineer, it is necessary to protect the intellectu-al property being developed. Joining a new network provides an entry point into the system. For the local network, whether a partner’s or a customer’s, let-ting a system not under its direct control

become part of the network may not be suitable for the organization’s security policies.

A third option is beginning to emerge. t involves not only engineer-ing laptops as client workstations, but “thin clients”, which are computers that depend heavily on other computers, and their server, to ful ll their computation-al roles. To bring this hardware togeth-er, engineers are utilizing a full- edged computer network and at least one serv-er with enough scalability, capacity and performance to take on many different types of design requirements and proj-ects, including analysis and simulation. The idea is to take your entire comput-ing environment with you, including servers, workstations, thin clients and network infrastructure.

This is not as dif cult as it may sound. Most professionals already carry a laptop with them that could serve as a low-to middle-end engineering work-station replacement. Routers need only be as large as the number of Ethernet ports they have, and cabling can be pur-

chased inexpensively at their destina-tion, or shipped separately.

The server might be a more challeng-ing prospect. At the heart of the engineer-ing-on-the-go or server-on-the-go con-cept is the Mobile Server. It is a capable engineering server that can provide the computational back end for design and low- to mid-range analysis and simula-tion tasks. While it might be odd to think of a laptop as a server, what really mat-ters is the power of its components.

Eurocom has begun coupling its EUROCOM Panther 5SE Mobile Serv-er with teams utilizing thin clients. A Panther 5SE Mobile Server is an all-in-one, 12lbs (5.5kg), easy to carry around system based on Intel Xeon E5-2600 v2 processor technology with integrated display, keyboard and built-in internal battery (UPS).

The Panther 5SE is designed for world wide deployment and easy net-work set up. It is easy to transport, move around and relocate, as it can t into a single carrying bag because of its all-in-one, compact design.

The Intel Xeon 12-core processors include exceptional multi-tasking capa-bility and additional L3 cache for speed-ing up data and instruction transfers. Being upgradeable, the system can also

incorporate up to two NVIDIA Quadro, GeForce or AMD Radeon graphics pro-cessing units. These can also be used to execute applications designed to make use of fast GPUs. While these systems often only offer 32 GB of memory and 6 TB of RAID 0/1/5/10 storage, that’s enough for many types of functions.

With a series of Thin or Zero clients

to provide the computational and graph-ics capabilities of a high-end worksta-tion, project teams are combining up to 10 or even 20 thin clients, that are basi-cally being powered by the Panther 5SE and its massive scalability, capability and robustness.

Together with engineering laptops, these servers can form the backbone of a network that can serve many de-sign engineering and lower-end analysis functions. In addition to computational resources, it can provide centralized and protected access to other networks and the Internet, enforce security policies, provide access to storage, and offer a number of other functions.

Engineers can now take their own full network with them on project de-ployments. An individual can put a server and an engineering workstation laptop in a carry-on bag, and have the beginnings of a network set up on-site within a few minutes.

A small city in the U.S., with a population of about 8,000, began upgrading its waste-water treatment facility in

2003. The new mechanical treatment facility was constructed near a housing de elopment and treats in uent primar-ily from residential customers. Less than 5 per cent is from commercial and industrial sources. The activated sludge, extended aeration system han-dles a ow of 8 ,000 gallons per day.

Average in uent biochemical oxy-gen demand (BOD) is 185 mg/L, with total suspended solids (TSS) of 1 mg/L. Mixed liquor suspended sol-ids (MLSS) are kept at approximately 4,000 mg/L. Ferric chloride is add-ed for phosphorus control. f uent is then processed through clari ers for solids removal. Biosolids generated at the plant are aerobically digested and stored in a covered tank located at the plant.

Two, 19 ft. deep earthen aeration ba-sins were also designed to provide ow equalization. An intermediate pump

station releases a constant ow and causes water levels to rise and fall in-side the basins. Disinfection is achieved with ultraviolet (UV) light.

In 2003, after considering several types of aerators, eight 15 HP high-speed oating aerators with stainless steel oats were purchased and in-stalled. Unfortunately, the oat systems began corroding at the water line. In addition to oat problems, the aerators also suffered from constant mechanical failures. The sales/service agreement with the manufacturer required replac-

ing the above- and below-water seal packs every six months.

With their mechanical problems con-tinuing to worsen, operators were then instructed to change parts every three months. When that didn’t work, it be-came every month. Costs mounted. Re-placing a shaft alone cost $2,500, plus bearing and seal costs. When it was sug-gested that all of the aerator parts be re-placed at the factory every six months, at an additional $20,000 a year, the city

nally decided it was time for an up-grade.

After a little research, the city chose Aeration Industries’Aire-O2 Triton® process aerator/mixers. They have few wearing parts and the water-lubricated bearing allows smooth operation with-out arti cial and manually-applied lu-bricants. The unit features an on-board regenerative blower that can be pro-grammed to be cycled on and off, de-pending on dissolved oxygen levels and other optional process control require-ments. Turning the blower off allows for mixing only and denitri cation, as well as additional energy savings.

Also, the oat system is constructed of a molded low-density polyethylene with a UV inhibitor. This eliminated

oat corrosion problems.With the amount of money saved on

parts and energy every year, the city was able to purchase the rst replacement

With their mechanical problems continuing to worsen, operators were

Triton. As the budget allowed, eventual-ly all the aerators were replaced.

Records kept by staff revealed that, before they upgraded their treatment plant with Aire-O2 Tritons, the waste-water treatment plant used about 37 kWh of electricity per day. After the upgrade, it only uses 17-19 kWh per day. This is a 50% savings! The aera-tor/mixers are designed to perform at a lower speed of 900 rpm, which allows for larger mixing propellers and more ef cient oxygen transfer.

The project stretched out over nine years and two construction phases. However, the city now has a fully op-erational wastewater treatment facili-ty, with an upgraded system that has slashed maintenance and electrical costs.

There are a few options on the mar-ket for surface-mounted mechanical aerators. It is always recommended to examine options by reviewing websites, calling for references and checking up on plants that have the equipment in op-eration.

It is also advisable to choose the ap-propriate aeration technology for your application. Not all aeration systems are ideal for all treatment plants. In some cases, very small volumes or extremely large and deep volumes of water may be served best by the use of submerged dif-fused aeration systems, as long as main-tenance is kept up.

Aeration Industries provides a pro-cess aerator with the ability to mechan-ically isolate aeration and mixing from mixing alone for nutrient removal. The typical engineered solution involves multiple aerators set up to work as a

exible system. It can be automatically operated by a programmed PLC at the master control panel.

For example, the linkage between the aerators and dissolved oxygen probes can provide signi cant energy savings, by ef ciently maintaining the appropriate oxygen levels according to the load entering the plant. In addition, the use of an automated oxygen reduc-tion potential system allows for precise denitri cation control. This is important in meeting strict nitrogen ef uent levels

Chemicals can help control biological growth and min-eral precipitation, but only mechanical ltration can re-

move the tons of suspended solids that every cooling tower grabs from the atmosphere each year. A thin layer of mineral deposits, the thickness of only a few sheets of paper, can have dramatic negative effects on cooling ef ciency.

o overcome inef ciencies, more water has to be pumped, which means higher utility costs and lower pro t. f spray nozzles plug, someone has to manually remove and replace or clean them.

Automatic self-cleaning lters can solve most of these issues. Capital costs will be higher than manual bag or car-tridge lters, but operational costs will be at a minimum, and human error is taken out of the equation.

wo basic ltration systems are most often utilized. he rst is side stream ltration. hen protecting heat exchangers, chillers, compressors and cooling jackets, this method is the most economical, while still meeting perfor-mance expectations.

ypically, - of the full ow is pulled off the main line as a side stream and run through a lter. ypically, side stream ltration will usually main-tain the concentration of total suspend-ed solids (TSS) at a steady low level to protect heat exchange surfaces from deposition. The percent of full ow used in side stream ltration will be deter-mined by cooling system volume, TSS loading, ltration degree required, and type of suspended solids.

Sometimes, it is desirable to pull the side stream off the main header after the supply pump, lter the side stream and then re-introduce the ltered water into the main header. A booster pump will be necessary to add energy back to the side stream ow to overcome system losses in the ltration process. (See igure ).These losses show up as pressure losses due to valves, piping, ttings, ow-stream direc-tional changes and velocity losses.

Figure 1. Side stream filtration with booster pump.

f the main supply pump has excess capacity, the side stream can be taken from the main header downstream of the pump, run through the lter and dis-charged back to the cooling tower basin. This utilizes existing horse power and requires no booster pump. See igure .

A third side stream scenario, often called a kidney loop, uses a small dedi-cated pump to take water from the cool-ing tower basin, run it through the lter and back to the tower basin. See igure 3. This system is totally independent from the main cooling system and can-not negatively interfere with the cooling

process. An example of this type of side stream lter is shown in igure . The particular lter skid shown will handle a cooling system of up gpm ( gpm through the lter).

ANNOUNCEMENT

Raymond J. Wilcock appointed Executive Director of

the Corrugated Steel Pipe Institute (CSPI)The CSPI Board of Directors is pleased to announce the appointment of Raymond Wilcock as its Executive Director, effective April 1, 2014. Mr. Wilcock replaces David J. Penny, who will then assume the role of Director Emeritus.

Over the past two decades, Mr. Wilcock has held progressive, senior executive po-sitions at several corporations, including those of V.P., General Manager, V.P. Opera-tions, and CFO at Armtec Limited, a diver-sified provider of materials and solutions to infrastructure markets.

“From the experience garnered during his various executive roles in our industry, Ray brings to CSPI exceptional knowledge and a deep understanding of all aspects re-lated to the strategic position of our prod-ucts in the infrastructure, agricultural, forestry and mining markets,” says Kenzie MacPherson, President of Atlantic Indus-tries Ltd. (AIL), a CSPI member company.

“I am extremely excited about tackling this new challenge and I look forward to renewing relationships as well as estab-lishing new ones,” says Mr. Wilcock. “As an

industry veteran, I’ve worked closely over the years with CSPI and other industry bodies on a number of major projects, in-cluding serving on the MTO Gravity Pipe Design Guidelines Committee and on the Ontario Road Builders Association Board of Directors. One of my strengths is stra-tegic planning and, as CSPI continues to evolve through technical innovation from R&D findings, I hope to channel those de-velopments through aggressive marketing of new CSP products to educate the mar-ketplace regarding their significant cost/benefits to owners,” he concludes.

“I’ve known Ray for more than 30 years, and can assure you he’s passionate about corrugated steel pipe and the heavy construction industry, and will bring vast knowledge and continued enthusiasm to CSPI,” says David Penny, “and I look for-ward to working closely with him during our transition period.”

Specifying

As industries recognize grow-ing numbers of new prod-ucts entering the Ontario marketplace, it is increasing-

ly important to determine the consisten-cy of product performance and quality. The 2006 Edition of the Ontario Build-ing Code addresses numerous products and required Test Standards, which are designed to pro ide speci c le els of product quality and performance.

In an effort to provide a monitoring mechanism that will assure the product quality we require, the Standards Coun-cil of Canada has approved a number of Testing Agencies that are deemed quali ed to perform the required testing procedures to satisfy the existing Test Standards.

There is debate within Ontario mu-nicipalities, on the differences between products which are “Tested”, vs. prod-ucts which are “Listed.” This article

highlights and clari es some of the mis-conceptions regarding what is required, why it is required and how to avoid po-tential liabilities.

Tested ProductsFor a fee, manufacturers have the

option of submitting product samples to a recognized testing agency to have them “Tested” or “Listed” to a speci ed standard. At the time of submission, the manufacturer may be required to indicate

their request for “Testing” or “Listing”. If a product is submitted for the purpose of “Test Only”, the testing agency has the liberty to perform the testing procedure in a manner required by the client (man-ufacturer).

It is important to note that in the case of a “Test Only,” the testing agency would not be required to adhere to the speci c testing procedure identi ed by the actual standard.

After completing a “Test”, the testing agency provides the client with docu-mentation that identi es the results, stat-ing that the results are based on a “Test” and do not imply that the product is List-ed or Certi ed.

When a product is submitted for “Test Only”, the results are based only on the products or materials that have been “Tested” for that report, and will not be subjected to any follow-up examinations to determine subsequent material quali-

Understanding the difference between “Testing” vs. “Listing” By Mike Speziale

45-Listing vs Testing.indd 68 3/28/14 1:05 AM

Poland’s territory is significantly divided into agricultural and woodland areas: 61% of the country territory belongs

to the first, 31% to the latter. Most of the agricultural areas in Poland are ecological farms, whose area tripled over the ten-year

period ending in 2012 reaching 35 thousand hectares. Polish farmers improve as well their ability to manage the wastelands,

contributing to reclamation of significant part of the land. The challenge of limited water resources promoted and motivated

a more reasonable and steadily decreasing use of water in Poland – between 2000 and 2012 water consumption in Poland

fell by 2% both in industry and agriculture. The process is accompanied by improvements in the water supply network, wa-

stewater treatment plants and sewage networks, constantly growing bigger and more efficient. Last but not least, 32.5% of

Poland’s area is protected as national parks due to its value and biodiversity as national parks. All 23 national parks in Poland

are listed by the International Union for Conservation of Nature, 9 are considered by UNESCO as biosphere reserves and one

belongs to World Heritage. Poland belongs as well to the Nature 2000 program which aims at protection of important lands.

Environmental protection in Poland involves a great

deal of innovative solutions and ideas. With implementation of

GreenEvo – Green Technology Accelerator, a tool introduced by

the Polish Ministry of Environment, young businesses in the field

have better chances to obtain financial and promotional support

and accomplish the most edge-cutting ideas. The new strate-

gy of Ministry of Economy “Innovativeness and Efficiency of the

Economy – Strategy for 2012-2020. Dynamic Poland” stresses the

importance of green technologies, balanced energy production

with green energy sources and the creation of green workplaces

by 2020. Additionally, program GEKON – Environmental Concept

Generator, is an important step: it provides financing on all stages

of research, development and implementation of an innovation.

Poland also participates in the Environmental Technologies Ve-

rification program of the European Union – a new initiative that

helps eco-friendly technologies be tested by creating a network

of developers and Verification Bodies or testing laboratories.

Polish environment protection is divided into three

main areas: public sector (incl. central government, provincial and

municipal bodies); economic sector – enterprises, financial institu-

tions, insurance institutions and non-commercial institution and

households. The investment in environment protection in Poland

is also co-financed through banks and grants from international

assistance, e.g. European Union funds as well as the Polish state

budget through the National and Provincial (Voivodship) Funds

for Environmental Protection and Water Management. Poland’s

expenditure on environmental policy are between 0.6% - 0.8%

of GDP each year and 0.2% on water management. In 2009-2012

the amount was 66.2 billion PLN (24.0 billion CAD), while for 2013

-2016 it is 63.5 billion PLN (23.1 billion CAD).

Polish experience proves that it is possible to effectively

reduce the pollution while maintaining a high economic growth.

Since 1988 Poland has reduced harmful emissions by more than

30 %, and is continuing this process in subsequent years. Poland

has made a big step towards reducing the emission of greenho-

use gases. Total emission of CO2 was reduced by over 30 % com-

pared to the value from 1988, NOx - over 40%, SO2 - 75 % and the

PM - 80%. Also the emissions of heavy metals and exhaust fumes

as well as the amount of wastewater have been reduced while the

Polish industrial production in this period almost doubled.

In Poland, the amount of energy produced from rene-

wable energy sources is steadily growing. According to data from

the Central Statistical Office in Poland (GUS) electricity generated

from renewable energy in 2012 accounted for 10.6 % of the natio-

nal gross electricity consumption. The energy produced from so-

lid biofuels amounted to 56.4 % of the total electricity production

from renewable energy sources in 2012. The amount of electricity

generated from other renewable sources for 2012 were: 28.1% for

wind power, 12% for solar energy and 3.3% from biogas.

ty, performance or consistency. Since follow-up examination is not required for a “Tested” product, there is no way of determining any changes in material consistency or product performance, that may occur between the time of “Testing” and the time of production.

On occasion, manufacturers have dis-tributed excerpts of “Test” documents that are several years old. Unfortunate-ly, some authorities have been led to be-lieve that the “Tested” product was equal to that of a “Listed” product. It is well known that information taken out of con-text, or documents that are incomplete, can prove to be misleading.

Listed ProductsWhen a product is submitted to a test-

ing agency with the intent of receiving a erti cation or “Listing”, the testing agency is required to be much more dili-gent in determining the material charac-teristics and performance capabilities.

In order to “List” a product or materi-al, it is necessary for the testing agency to follow the precise testing methods identi-

ed by the Test Standard. In doing so, the testing agency is required to monitor and record all pertinent data throughout the testing program, in order to determine the product’s compliance with the Stan-dard. Once the testing process has been completed, the testing agency provides the manufacturer with documentation in-dicating the results.

If the product receives a positive re-sult, meaning that it satis es the require-ments stipulated within the Standard, it is then eligible to be erti ed Listed.

Clients who undertake “Listed” ex-aminations, are subject to ongoing fol-low-up production and performance examinations that will determine the consistency of compliance. By “List-ing” a product, the manufacturing fa-cility, material compound and product performance all face random “Testing” by the “Listing Agency.” If any changes are identi ed when the “Testing” takes place, Certi cation could be lost. The cost for “Listing” a product is substan-tially higher than the cost of “Testing.”

Each time the Agency visits the man-

ufacturing facility to con rm product sta-bility, there are associated costs charged to the manufacturer. When a third-party “Testing Agency” publishes a “Listing”, the documentation will indicate that there be speci c identi cation markings on the product, for example, the name of the “Listing Agency” accompanied by their logo and the required “Test Stan-dard”. In addition, in most cases it will require that the product bear a summary of the test results, such as ame-spread rating, smoke classi cation, etc.

By examining the differences between products that are “Tested” vs. “Listed,” factors that may potentially compromise the objectives of the Ontario Building Code may be uncovered.

There is no doubt that the issues within this article will require increased scrutiny on the part of inspectors, and in-creased costs incurred by manufacturers.

owever, the bene ts to public safety are signi cant.

Support for Lake Winnipeg projects reaffirmed

The Government of Canada has reaf-rmed more than million in previous

funding for communit stewardship projects that have helped to restore the health of Canada’s sixth-largest lake.

ast ear, the Global Nature und declared Lake Winnipeg the “Threat-ened Lake of the Year”, citing large amounts of blue-green algae. Phospho-rus and nitrogen from agricultural and sewage run-off have caused larger and more frequent algae blooms which im-balance the lake’s ecos stem and can be toxic to humans.

This funding is part of the Lake Winnipeg Basin Initiative (LWBI), which supports stewardship projects, scienti c research and monitoring, and trans-boundar management efforts to improve water qualit in Lake Winni-peg. The LWBI was launched in 2007, and has provided million in funding for projects including wetland resto-ration, innovative wastewater treatment, new agricultural practices, and research.

duce the amount of coal used by more than 4,500 tonnes every year, reducing greenhouse-gas emissions by approx-imately 7,000 tonnes as a result. The amount of biomass available for use is expected to increase by 7,600 tonnes an-nually as a result of the funded projects.

Sixteen grants will help farms convert from coal to renewable biomass energy. The other four recipients are processors who will use the funding to improve capacity and ef ciency in their businesses.

Manitoba has committed to use coal and petroleum coke (petcoke) tax revenues to help coal users convert to biomass. The province implemented

orth merica s rst coal heating ban on January 1, 2014. If an approved con-version plan is submitted by June 30, a grace period to comply will extend to July 1, 2017.

These grants also support the prov-ince’s bio-products strategy, created in 2011 to encourage the development of value-added processing in rural and northern Manitoba’s agriculture and for-estry sectors.

Since 2000, Manitoba’s population has increased by 11 per cent, the econo-my has grown by 31 per cent but green-house-gas emissions are down by two per cent. This information is from the recently released 2012 provincial cli-mate change report.

New water legislation introduced

British Columbia Environment Minister Mary Polak has introduced legislation that will update and replace B.C.’s cen-tury-old Water Act with the new Water Sustainability Act. It will be brought into effect in spring 2015, once sup-porting regulations are developed and

nali ed. Input from individual British Columbians, irst ations organi ations and stakeholder groups contributed to the Act.

According to the provincial govern-ment, “the new Act will, most notably, bring groundwater into the licensing system, and will expand government’s ability to protect sh and a uatic envi-ronments.” It will make improvements

Reinvent the Toilet Challenge

More than 45 exhibitors representing 15 nations met in New Delhi recently, showcasing innovative products and ap-proaches that aim to bring safe, afford-able and sustainable sanitation to the 2.5 billion who lack access to sanitation.

Co-hosted by the Department of Bio-technology and the Gates Foundation, exhibitors featured projects to stimu-late discussion among a diverse group of stakeholders working to improve global sanitation. Teams created and displayed toilets that are not connected to water, sewer or electricity; improve the collection, treatment and disposal of human waste; address behavior change; and raise awareness of this critical issue for governments, stakeholders and local communities.

For a look at the solar power toilet developed for the challenge by the Uni-versity of Colorado Boulder, see page 40.

We’re fortunate to live in Canada, one of the world’s great nations. Accordingly, it is incumbent upon all of us who work in water/soil management to protect our abundance of precious resources, for our children and for generations to come.

We can all participate in this stewardship by improving the products, innovations and technologies used to manage our infrastructures and other resource related sectors to maintain our standard of living, while ensuring Canadian industry remains globally competitive.

That underscores the importance of the jobs we all do, day in and day out. Which is why CSPI created In The Trenches – an online industry newsmagazine for sharing information and new ideas. For many of us, its title may be a metaphor; but, it also re ects the reality that, regardless of whether we operate a backhoe, analyze water and soil, or sit at a computer creating things, we really are all in this together.

That’s why CSPI and its members encourage everyone in the industry to openly share their news, knowledge, successes and insights of how to do things better for less. Sharing knowledge empowers us all to succeed in making a better Canada.

We’re all members of this vital industry sector. And membership has its responsibilities.

For more news from In The Trenches visit us at cspi.ca
