Innovative new on-line particle sensor

Analytical Technology (ATi) has introduced the innovative laser-based C10/77 Particle Sensor, for the continuous on-line monitoring of particle counts in raw water, filter influent and filter effluent

Analytical Technology (ATi) has introduced the innovative new C10/77 Particle Sensor, for the continuous on-line monitoring of particle counts in raw water, filter influent and filter effluent.

Based on a laser light blocking principle, this novel sensor can provide particle count data over size ranges from two to 200 microns, with three 4-20 mA analogue outputs and an RS-232/485 digital output supplied as standard. ATi currently has over 75 of these monitors working in various water companies in the UK.

Turbidity monitoring of filtered potable water provides an excellent indicator of water clarity as well as a reliable measure of general filter efficacy.

Asahi Kasei's Microza Hollow Fiber Filter Membrane Technology Chosen for US Waterworks

The Microza™ hollow-fiber membrane filtration system has been selected for a new waterworks facility to serve the metropolitan area of Minneapolis, Minnesota, with full-capacity operation scheduled to begin in January 2011. Located in Fridley, the plant will have a water treatment capacity of 360 thousand m3/day. This will make it one of the largest drinking water plants in the US, and among the largest plants anywhere to utilize a pressurized membrane filtration system for water purification. Selection was concluded after extensive testing and evaluation by the Minneapolis Water Works, confirming the outstanding performance of the Microza™ system.

Membrane filtration offers many advantages over conventional water treatment by sedimentation and sand filtration, notably the ability to efficiently and reliably achieve high rates of removal of pathogenic microorganisms such as cryptosporidium. With stringent regulations for removal of cryptosporidium from drinking water supplies scheduled to come into effect in the US, the adoption of large-scale membrane filtration systems for water treatment is projected to grow substantially.

EPA Awards $5 Million in Safe Drinking Water Grants

10 universities received grants from EPA for research to develop better methods for detecting harmful organisms in drinking water, including viruses, bacteria and protozoa. The grants, awarded through EPA's Science to Achieve Results (STAR) research grants program, are aimed at ensuring that the United States has the safest drinking water in the world.

"These five million dollars in grant money are an example of how EPA puts science to work to protect human health," said Dr. George Gray, EPA's assistant administrator for research and development.

Every year, there are cases of gastrointestinal (GI) illnesses in the United States associated with drinking water. EPA's sponsored research will result in faster and more sensitive tests for local drinking water facilities to use in detecting pathogens. The sooner a contaminant is identified, the faster a facility can act to contain the problem, and thereby reduce any health risks to the public.

How we coped when water turned muddy

With the boil-water advisory still in effect in Vancouver, Burnaby and the North Shore, stores are being stormed by people looking for water treatment systems. But consumers need to look around to determine what's best for their health and their pocketbook.

The cheapest solution is boiling water, and that means a rolling boil for at least one minute, Vancouver Coastal Health's manager of health protection, Richard Taki, said in an interview.

But boiled water tastes pretty flat so Taki suggests letting it cool and then transferring the water back and forth between containers to give it some flavour.

Health Authority asks to protect water supply

Wednesday, 04 October 2006

Robson Valley Times

The Northern Health Authority is asking Valemount to upgrade its water system to be able to guard against cryptosporidium. Bruce Gaunt, the man in charge of drinking water with the health authority, wants the village to take the next step in water treatment.

“Despite the good quality of the water source, almost firsthand from the mountain, there is a risk of waterborne protozoa. Giardia is one that has been well identified. There is another one called cryptosporidium,” said Gaunt.

Gaunt said that Valemount suffered an outbreak of giardia in 1996. However the present system doesn’t guard against cryptosporidium.

He said that Valemount has done some work in preparation for the outbreak, now he’s asking them to take the next step.

Cryptosporidium is resistant to chlorination and it is only in recent years that there are treatments that can eliminate it.

“This is still a risk factor for the municipality and the need to deal with that as well,” he said.

He said that cryptosporidium is a pathogen in temperate water systems that can cause diarrhoea and cause a crippling illness to those with suppressed immune systems.

Cryptosporidium is endemic, meaning that just about any surface water source in the province likely contains it.

“If you ever been on a farm and had calves with scours, that is an attack of cryptosporidium,” he said

He said that so far, there hasn’t been an outbreak in northern B.C., but prior to 2000 there were outbreaks in Kamloops and Kelowna. He said that there was a widely known attack in North Battleford in 2001 and that Victoria and Kamloops are bolstering their water supply against the organisms.

“There comes a point when chlorination needs to be augmented,” he said.
He said that the number of tourists coming to Valemount is a good reason to treat the pathogen.

“We have rather a high preponderance of hotel rooms when we consider the population. It’s not like we’re just considering the population of Valemount. We have people coming enroute from Edmonton to Vancouver. Some of those travellers are not used to an organism challenge if they were to receive it,” he said.

“When you are dealing with drinking water more than with any other kind of intervention, you affect more people in a more profound way than anywhere else.”

He said that a dirty restaurant only affects people who eat there, but anybody who stops into town, especially if they stay overnight, are going to be impacted by the town’s water supply.

“How do you quantify what is relatively less risky when you are dealing with people from all walks of life and different communities passing through? If you have the ability to deal with a pathogen, a disease-causing organism, and we’re not doing it, we make ourselves vulnerable to having an outbreak,” he said.

He said that the village would be able to obtain substantial assistance for this.

“We have such cheap water anyhow; we tend to think that it is free. It isn’t free. There comes a cost to have water delivered to your tap under pressure.”

When municipalities begin to become concerned about the costs, Gaunt compares the cost of treating water to other utilities elsewhere in the country.

“It’s a good news story for Valemount. It’s a worthwhile program,” he said.
The Village of Valemount is taking the request seriously. At last Tuesday’s meeting councillors resolved to ask Urban Systems to pursue a planning grant for water system enhancements. Urban Systems had been developing a proposal for the village square concept under the provinces Infrastructure Planning Program; however, they will try to use another fund to continue that process.

Spray Park Remains Closed

(Geneva, N.Y.) - An Ontario County spray park that shut down last year after thousands became sick from contaminated water will not reopen this week as planned.

The Seneca Lake State Park Sprayground has installed ultraviolet lights to kill bacteria that infected visitors. The system has not been tested.

Officials hope to complete testing this week and reopen the park by the end of August.

Shedding light on water quality

The Chetek Alert

The recent flushing of the water system caught the attention of many Chetek residents, but the practice is standard operating procedure. What is new to Chetek's water treatment is the use of UV light treatments and the city's participation in a study.

In the last few weeks a rumor concerning the city's tap water began circulating. Claims that the city was forgoing chlorine treatments in place of UV light treatments had people questioning the safety of their water.

According to Director of Public Work Dan Knapp, the city of Chetek does not use a chlorine based water treatment system.

"We use chlorine only when we have been working on the lines to eliminate any potential bacteria that may have entered the system during repairs," stated Knapp.

Following the repairs to the water tower, chlorine was used to remove any bacteria that may have developed. The chemical was then flushed through the system, which resulted in a strong chlorine smell whenever the tap water was turned on. The flush of the system is also the reason behind the running hydrants spotted by residents.

What should be catching the attention of the city's residents is Chetek's participation in a unique water treatment study, which examines the risk of acute gastrointestinal illness and fever in children who drink water from municipal systems that use groundwater.

All city residents were informed my mail of the study which uses UV light purification in addition to the city's current methods of treatment. The WAHTER study, which is being conducted by the Marshfield Clinic Research Foundation and funded through federal dollars as part of the Safe Drinking Water Amendments in 1996, is the first of its kind in the world.

According to Mark Borchardt, the study's principal investigator and a scientist with MCRF's National Farm Medicine Center, the Environmental Protection Agency (EPA) commissioned the study after it was acknowledged that no one knew exactly how safe the surface and groundwater supply was under current treatment methods.

"When Congress approved the amendments they asked the EPA to conduct studies to estimate the incidence of waterborne disease in the United States.

This study is designed to estimate the proportion of illness in children due to drinking groundwater," Borchardt said. "It is amazing to think that no real studies have been completed until now."

In fact, the Federal Drug Administration has done extensive studies on the safety of food, but when it came to the nation's water supply the government had "no clue," stated Borchardt.

Groundwater has been perceived as pure, but between 1991-2000, more than two-thirds of the 163 waterborne infectious disease outbreaks in the U.S. were attributed to groundwater contaminated by viral, bacterial or disease-producing agents. While disease outbreaks are alarming, there are far more sporadic individual cases, and the source of these infections is not always clear.

The water sources identified as needing to be studied were ground and surface water. The federal governmental set aside $3 million for the research. The studies on surface water began first because it was believed that the greater source of contamination would be found here.

"The study was held in Davenport, Iowa. What they found is that there was only a small risk of contamination," Borchardt noted. "Considering the source of water is the Mississippi River, this was very good news."

Borchardt says that the findings are reassuring because it gave scientific proof to the fact that standard water treatment methods are being effective. However, the study used all of the funds the government had set aside delaying the groundwater studies.

Last year, Borchardt was awarded $1.8 million by the EPA for his proposal.

Lighting up Chetek's water

"Instead of installing a UV light system on individual household taps and asking people to only take water from this one source, we realized that people are exposed to water through many sources," the scientist explained. By treating a community's entire water supply with a Wedeco UV light system, the Marshfield researchers could better assess the impact of the treatments.

"I think one of the reasons this approach hasn't been taken before is because nobody believed they could get entire communities to participate, but they don't know Wisconsin," stated Borchardt.

Fourteen Wisconsin communities from a pool of 40 were selected to participate in the program. Criteria for selection was based on three factors: the city's water must come from a sand/gravel or sandstone aquifer, the number of wells feeding the communities was limited, and a sufficient number of families with children would be available to participate in the study.

"Test communities are being given a chance to use key technology free of charge," stated Borchardt. "This is equipment that is expensive to purchase and install, but it is being made available through federal funding."

The plan is that after six months, the two sets of communities will "cross over," meaning the ultraviolet light units will be moved to the original control communities. All 14 communities will be tracked for another six months.

Taking part in the study

After speaking with Knapp, Borchardt determined that Chetek would be one of the test communities because it met the main criteria. Currently, every person in the city is using and consuming UV light treated water. Seven control communities will continue current water treatment practices.

Surveillance for gastrointestinal illness and fever will be conducted among children in participating households.

In Chetek families are still needed to participate directly in the study by completing a health symptoms checklist four times over the next 12 months. Only 30 of the 62 families needed to produce statistically viable results have registered to be active participants in the study.

"Among the 14 communities in this study, over 1,780 people have already agreed to participate," Borchardt said. "In Rice Lake we had to turn people away."

The researchers are looking for households using city water with at least one child who is at least 6 months old and less than 13 years old. Participants are paid $100 per family if all study procedures are completed. In addition, at the end of the study a drawing will be held for one family from each study community to win a free two-night get-away at a Wisconsin Dells hotel and water park.

"You can't pay people enough for their time. We find that people participate because they are concerned about their kids and their health," noted Borchardt.

Borchardt added that the communities need to understand that there is no danger associated with the level of UV light being used in the study.

Ultraviolet disinfection uses a UV light source, which is enclosed in a transparent protective sleeve and placed in a water flow chamber. When ultraviolet energy is absorbed by the reproductive mechanisms of bacteria and viruses, the genetic material (DNA/RNA) is rearranged and they can no longer reproduce. The organism is then considered dead, eliminating the risk of contamination.

UV treatments disinfect water without adding chemicals. It does not create new chemical complexes, produce any bi-products, alter the taste, pH, or other properties of the water, or remove any beneficial minerals in the water.
For this reason, UV light treatments are also considered environmentally friendly. Studies show that ultraviolet devices are most effective when the water has already been partially treated, and only the cleanest water passes through the UV flow chamber.

In the U.S., chemical treatment with chlorine remains the primary method for disinfecting drinking water. However, chlorine can produce chemical by-products that have been linked to cancer. Such byproducts are also coming under stricter regulations in the new EPA rules for drinking water.

"If we were to try to introduce chlorine today with the protections in place from the EPA, we couldn't do it," Borchardt added. The EPA started including UV disinfection as an approved water treatment method in 1998.

When chlorine gas or sodium hypochlorite are used to disinfect water, they react with organic compounds in the water to form potentially harmful levels of the chemical by-products trihalomethanes (THMs) and haloacetic acids, both of which are carcinogenic and regulated by the U.S. EPA. Chlorine also fails to kill some infectious microbes, such as the protozoan parasite Cryptosporidium. Known as "Crypto," in the last two decades the parasite has become recognized as one of the most common causes of waterborne disease among people in the U.S., according to the Centers for Disease Control and Prevention. The organism, Cryptosporidium, caused a major epidemic infecting 400,000 people in Milwaukee through the drinking water in 1993.

Families wishing to become an official part of the study have until Wednesday, May 31, to contact the Marshfield Clinic Research Foundation toll-free at 1-877-233-7533 between the hours of 7:30 a.m. and 4 p.m.

LA County Aquatics Warns Commercial & Residential Swimming Facilities about Pool Health and Illness

5/11/2006
To: Metro Desk, Health and Features reporters
Contact: LA County Aquatics, 866-966-7665

LOS ANGELES, May 11 /U.S. Newswire/ -- Even the best maintained pools can spread illness. Since 1988, Recreational Water Illnesses (RWIs) connected with swimming pool have been on the rise. Last summer the splashpad-associated outbreak of Crypto affected almost 3,000 people in Seneca Lake, N.Y. In 1998, the waterpark outbreak of E. coli O157:H7 resulted in seven children having kidney failure, and one death.

The week proceeding Memorial Day has been designated as National Recreation Water Illness Prevention Week by the Centers for Disease Control and Prevention. LA County Aquatics will participate in this year's observance, which takes place May 22 - 29. The focus will be on operation and prevention tips for pool operators and pool patrons to encourage a healthy swimming experience.

Swimmers may wonder -- doesn't chlorine kills germs? It does, but it doesn't work immediately, and it takes time, says L.A.C. Aquatics. The good news is that outbreaks caused by E. coli O157:H7 appear to be rare if free chlorine levels are maintained at recommended levels throughout the pool. However, germs like "Crypto" (Cryptosporidium) are resistant to chlorine and can live in swimming pools many days. Crypto can be life-threatening and sometimes fatal in persons with compromised immune systems, persons who have received an organ transplant, patients taking certain immunosuppressive drugs or those who are receiving certain types of chemotherapy. Recreational Water Illnesses like Giardia, Shigella and E. coli O157:H7 are usually spread by accidentally swallowing water that has been contaminated with fecal matter. Even spas can spread a variety of germs (e.g., Legionella and Pseudomonas) that can cause skin and respiratory illnesses if disinfectant levels are not properly maintained. Furthermore, patrons may not associate their symptoms such as diarrhea and skin rashes, the most common RWIs, because the illness can appear days after swimming.

Having a Certified Pool Operator servicing your aquatic facility can be beneficial. However, many are not aware that all facilities serviced, public or private, located in the County of Los Angeles, are not only required to have a Certified Pool/Spa Operator or other approved certification, but are also required to be a certified Los Angeles County Pool Service Technician or Swimming Pool Apprentice Technician. Many health clubs, hotels, and residential facilities are not aware and may be in violation, according to L.A.C. Aquatics. Patrons should remember to ask questions of the pool staff. Are chlorine and pH levels checked at least twice a day? Are trained operation staff available during the weekends when the pool is most heavily used? What was the health inspector's grade for the pool after its last inspection? Also, says LAC Aquatics, patrons should remember to avoid swallowing or getting pool water in your mouth. Refrain from swimming when you have diarrhea. Take children to bathroom breaks and do not change diapers at poolside.

In recognition of National Recreation Water Illness Prevention Week, L.A.C. Aquatics is offering a free pool inspection including water balance analysis to facilities until May 31 (a $75 value). For more information call 866-966-7665 or visit: http://www.lacountyaquatics.com/poolsafety.htm

NY rules: UV disinfection at pool "spraygrounds"

Water Technology Daily

05.10.2006

SARATOGA SPRINGS, NY - As municipalities prepare to open public pools for the summer, the New York State Department of Health (DOH) has enacted a regulation that requires recirculated water in recreational pool "spraygrounds" to be treated with ultraviolet (UV) light, according to a May 9 report in The Saratogian.

Last year, the DOH forced small-city wading pools to renovate spraygrounds after an outbreak of Cryptosporidium sickened 1,800 people who had visited Seneca Lake State Park in Geneva, NY, as reported by Water Tech OnlineĈ in August 2005.

Officials in Saratoga Springs said they will not install a separate UV disinfection system at their four sprayground areas, but they plan modifications that will spray fresh, unrecirculated water from the city system, the report said.

Because the water will not recirculate, officials will install replacement nozzles to keep water use down, the report said.

Cryptosporidium causes intestinal illness with symptoms that include diarrhea, abdominal cramping, nausea, vomiting, fever and headache.

City faces new regulations for spraygrounds

CHRISTOPHER DIAKOPOULOS

The Saratogian

SARATOGA SPRINGS - The Department of Public Works is working to get the city's four "spraygrounds" open for play this year, despite new regulations from the New York State Department of Health requiring an additional water treatment system.

New regulations from the state Department of Health forced the city to close its four wading pools last year and renovate them as spray fountains. But with the outbreak of the bacteria cryptosporidium last summer at Seneca Lake State Park that resulted in more than 1,800 illnesses, the DOH changed the regulations again to include ultraviolet water treatment in addition to the chlorine system the city installed last year.

"We're trying to get ready for our opening and to meet the state standard," said WilliamMcTygue, director of Public Works. "We're not prepared to put in a separate UV disinfection system, but we are modifying our system to spray fresh water."

McTygue said the changes will bypass the chlorination system put in last year at the city's four parks at the West Side Rec fields, East Side Rec fields, South Side Rec and Geyser play area.

"It will be fresh water off the city system," McTygue said. "The DOH said that because we were recirculating the water, we couldn't do it without the UV and they didn't want to bend their new rule."

Assistant City Engineer Debbie LaBreche said the city required the bidder for the job last year, Concord Pools, to design the system to easily accept these changes in the future.

"We had input from DOH and we made sure we kept them abreast of what we were doing last year," LaBreche said. "We required Concord Pools to address DOH's suggestions, so when the regulations changes, this wasn't a big surprise."

Since the new design will be spraying fresh water off the city system, and then draining it to a waste pipe, the designs will use more water compared to the previous chlorination/recirculation system (similar to a swimming pool's system), but LaBreche said the replacement of some of the nozzles at the parks will keep the water use down.

"As long as we don't have any water restrictions, this will work," McTygue said.

According to the national Center for Disease Control, Cryptosporidium is a very common cause of waterborne disease. The intestinal illness caused by the bacterium, Cryptosporidiosis, carries symptoms including diarrhea, abdominal cramping, nausea, vomiting, fever, and headache. Until last year, New York had between 400 and 500 cases reported annually, according to the Department of Health.

Which Frenchman Thought of This?

The News-Banner
Opinion
May 1, 2006

Bottled water has always been a puzzle to me. Who came up with this idea? Why do Americans pay the equivalent of about $8 a gallon for something they can usually get for free down the hallway? How can a 12-oz. bottle of plain old water cost the same as or more than a Pepsi?

Can you envision that first entrepreneur approaching a group of investors or his local bank with his idea to take water, put it into 12-oz. plastic bottles, and sell it for $1 or more? Surely some thought he was nuts. But others were apparently smarter than me.

The first bottled water, at least as I recall, was all "natural spring" water or fresh from a "mountain stream." But, as a recent report revealed, much of the bottled water on the market today comes "straight out of the municipal water supply of Detroit."

What spurs me to get on this soapbox was an article I came across this week.

Some government office called the Natural Resources Defense Council studied every brand of bottled water they could find. Their tests showed that 22 percent of them did not meet the minimum standards for municipal tap water. It seems there are federal regulations that allow bottled water "to contain some contamination by E. coli, or fecal coliform, and don't require disinfection for cryptosporidium or giardi." Although few of us can explain just what those things are, I'd bet we all agree they don't sound good.

Americans consumed almost 26 billion liters of bottled water in 2005. There was also an article recently about gas prices that put part of the blame for high prices on bottled water. The resources needed to produce the plastic bottles for those 26 billion liters (not to mention the electrical power to fill them and the gasoline to distribute them) requires over 1.5 million barrels of oil, enough to fuel about 100,000 cars for a year.

Americans are not alone. In fact, we are somewhat behind many parts of the world in our bottled water consumption. This unexplainable phenomenon is not limited to our American shores.

Europeans are, at least by some accounts, the world leaders in per capita bottled water consumption. Which just proves my point. If the French think it's so cool, how good of an idea can it be?

Water compliance runneth low

Few public sources keep up with testing regulations
By Dan Stockman

The Three Rivers Filtration Plant has had just one minor violation from the federal Environmental Protection Agency in the past five years.

More than 300,000 people in Allen County depend on clean, safe water coming out of their taps every day for drinking, cooking and cleaning, but only a small minority of public water systems have complied with water testing requirements in the last five years to ensure water quality.

Of the 101 public water sources in Allen County, 75 systems in the last five years have had at least one monitoring or reporting violation, an analysis by The Journal Gazette found. Forty-six systems have had monitoring or reporting violations the U.S. Environmental Protection Agency deems "significant."

Twenty-four systems had health violations, according to the EPA, meaning contaminants in the water posed an imminent health risk.

Though most people think of public water systems as large, city utility systems, the state and federal government regulate nearly 5,000 systems in Indiana, including wells that serve mobile home parks, small schools and tiny cafes.

The violators included large systems such as Fort Wayne City Utilities' Three Rivers Filtration Plant and tiny ones such as churches and restaurants. One, St. Joseph Hessen Cassel Catholic School, racked up 55 significant violations in five years.

Cedar Creek Church of Christ Day Care in Leo-Cedarville had 29 significant violations; other systems had dozens of violations each.

Water systems are responsible for ensuring the testing is done, either through the Indiana Department of Environmental Management or a certified laboratory. For most small systems, this consists of filling bottles with water and sending them in.

If a test is not performed or the water does not pass the test, a violation is issued. Some tests must be performed monthly, others quarterly and some yearly. A large system such as Fort Wayne City Utilities must test daily.

The violations are issued and tracked by IDEM, then reported to the EPA. The Journal Gazette analyzed the data held by the EPA, which is available at www.epa.gov/safewater.

Experts said the number of violations may sound high, but not when you consider they are spread over five years.

Al Lao, section chief for compliance in the Indiana Department of Environmental Management's Office of Water Quality, said that although his office views every violation as "significant," on a monthly basis there are relatively few systems that are not monitoring their water properly.

At any one time, he said, there are usually fewer than 5 percent of the nearly 5,000 public water sources in the state that are not testing properly, he said.

"We require every system that has any violation ... to notify their customers what violation they have and what they are planning to do to correct the violation," Lao said.

Some of the violations accumulate quickly, Lao said, because an entire group of contaminants is monitored by one test. St. Joseph Hessen Cassel Catholic School, for example, in the third quarter of 2003 did not test for volatile organic compounds. Since that category covers 21different contaminants, the water system was deemed by the EPA to have 21 violations. IDEM does not view it that way, Lao said.

"We consider them to be one violation, because they missed one test procedure," he said.

Robert Herber, the principal of St. Joseph, pointed out that the violations were because tests were missed, not because of contaminated water. The school had one violation related to ensuring there is no lead in the water, but that has been resolved since 2003.

Herber said his concern is that parents will see the large number of violations and assume the water is unsafe, when that is not the case. Ensuring the water is safe is a top concern, he said, but just one of many responsibilities he has. Forty-two of the violations were from twice missing a 21-contaminant test.

"You're talking about children, and we should be extraordinarily safe in trying to protect them," Herber said. "As a parent, I want them to be safe when they go to school."

Cedar Creek Child Care, run by Cedar Creek Church of Christ, had 29 significant monitoring or reporting violations, all of them related to missed tests in 2004.

Jon L'hommedieu, a church member who oversees the testing, said he does not believe the EPA data showing 29 significant violations are correct.

"You start messing around with databases, anything can happen," L'hommedieu said. "I really do think something's been lost in the translation."

The violations were verified by IDEM, but some point out that sometimes the violation is IDEM's fault, saying that test results sent to the agency electronically sometimes get lost in IDEM's system -- resulting in a violation.

If there were problems at Cedar Creek Child Care, L'hommedieu said, they were all testing or reporting problems, as no contamination has ever been found in the water.

"That's key -- we've never detected a problem," he said. "As far as I'm concerned, the thing's totally safe."

He said there had been problems with "amateurs" trying to do the sampling before he took over and had it handled by a certified lab. The violations, which all occurred in 2004, could have come during the switchover, he said.

Phillippa Cannon, spokeswoman for the EPA's Region 5 office in Chicago, said ensuring the safety of the nation's drinking water rests upon self-testing. If those tests aren't done, there's no way to know the water is not contaminated.

"It's a self-monitoring system, and we rely on these systems to submit accurate and timely reports so we know their water is safe to drink," Cannon said. "That's just how the system works."

Ridgeview Mennonite Church in Woodburn has had three significant monitoring or reporting violations, and three non-significant violations in five years. The importance of that testing became clear when testing found coliform bacteria in the water, resulting in three health violations. The presence of coliform bacteria is a sign that the water may be contaminated with potentially harmful bacteria from feces. That requires chlorinating the well and flushing pipes to ensure the water supply is safe.

"We definitely don't want to do anything that's going to cause problems with anybody," the Rev. Lester Zehr said. "You definitely don't want your people getting sick."

On the other hand, while he wants to ensure the safety of his 75 church-goers, Zehr said the hassle and expense of meeting state and federal requirements is a burden.

For a while, the testing was free, he said, but is now about $30 per test. When tests have to be repeated, the cost adds up quickly, he said.

The EPA says a health violation, such as the three at Ridgeview Mennonite Church, does not mean those who drank or used the water got sick but that they were exposed to an "unreasonable risk of illness" or that the water wasn't treated to the extent EPA requires to prevent illness.

The federal Centers for Disease Control and Prevention statistics show 419 outbreaks of illness from contaminated drinking water between 1980 and 1998. But most of the estimated 511,000 people sickened in those outbreaks were from one case: the 1993 Cryptosporidium outbreak in Milwaukee.

Experts say the risk of thousands or even hundreds of thousands of people being sickened by one source is what makes testing so important. They also believe the number of people sickened is underestimated, because most healthy adults who contract a waterborne illness will have only mild symptoms and not report it.

AquaIndiana's north system, which serves 30,900 customers on the north side of Fort Wayne, had one health violation when coliform was detected in the water in September 2004, and one significant monitoring violation, in 2003.

Fort Wayne City Utilities, which serves 250,000 customers, garnered a non-significant violation in 2001 when it sent a certification in late.

Other systems with violations included the state-run rest areas on U.S. 30 near Arcola, both of which have had seven significant violations in the last five years. The Indiana State Police Post in Fort Wayne has had five significant violations and 12 non-significant violations in the last five years.

City goes ahead with spray park plans

By Mark Langlois THE NEWS-TIMES

DANBURY - City officials will push ahead with plans to create a spray park for Rogers Park although thousands became ill at similar parks in New York and Georgia.

Danbury leaders say the city's situation is different from the others.

The New York and Georgia parks didn't have treated municipal water and used reservoir water without treatment. They stored runoff from the sprayscape in tanks under the park and pumped it out again, so any contamination from people using the park was concentrated in the tanks.

That may have contributed to the sickening of 4,000 people near Seneca Lake in New York in 2005.

"When that was happening, we were following it carefully," said Danbury Health Director Scott Leroy. "The state of New York was making recommendations, and we are taking them seriously."

The Centers for Disease Control and Prevention said a similar outbreak in 1995 affected more people -- nearly 5,500 -- in Georgia.

"In New York, the water supplies are surface water supplies. What we have here is a municipal water supply that is filtered, treated and chlorinated," Leroy said.

Danbury wouldn't use holding tanks.

The state Department of Health's Recreation Water Supplies section doesn't have regulations for sprayscapes in Connecticut. The department said if the city recycles its water, state swimming pool regulations apply.

"We designed it to avoid those problems," said Danbury Mayor Mark Boughton. "There are 10,000 sprayscapes throughout the country and most are operating safely."

New York State's regulations say spray parks that recycle water must have county health department permits. Signs must be posted telling people with diarrhea to stay out of the water. The parks must have filters, and fences to keep animals out of the water park.

When New York completed its spray park regulations, officials said the bacteria that caused the diarrhea was found in storage tanks at the Seneca Lake water park.

While not recycling water is wasteful, the city must balance health needs with recycling goals, said Public Works Director Bill Buckley. "It's a balancing act we have to follow."

Buckley said plans for the sprayscapes at Rogers Park and at Highland Avenue Park will be forwarded to the state to make certain the city is following state guidelines.

The state is asking the city to maintain a chlorine level for water leaving the park of just under one part per million.

EPA Hopes New Rules Will Improve and Protect Drinking Water

(AXcess News) Washington - The Environmental Protection Agency said Thursday that it finalized two related drinking water protection rules - one that reduces the risk of disease-causing microorganisms from entering water supplies and the other that requires water systems to limit the amount of potentially harmful "disinfection byproducts" (DBPs) that end up in our drinking water.

Signed as the EPA enters the 31st anniversary year for the Safe Drinking Water Act, the rules were proposed in August 2003, and were developed from consensus recommendations from a federal advisory committee comprised of state and local governments, tribes, environmental, public health and water industry groups.

"Clean drinking water is a key ingredient to keeping people healthy and our economy strong," said EPA Administrator Stephen L. Johnson. "Over the past seven years EPA has worked collaboratively with stakeholders to develop regulations that will provide a balance between the need to disinfect drinking water and protect citizens from potentially harmful contaminants."

The rules are important public health measures that will decrease the incidence of gastrointestinal illnesses caused by microbial contaminants and reduce potential cancer risks associated with disinfectant byproducts in drinking water. Finalizing the two rules represents the last phase of a congressionally required rulemaking strategy under the 1996 Amendments to the Safe Drinking Water Act.

Long Term 2 Enhanced Surface Water Treatment Rule (LT2)

The "Long Term 2 Enhanced Surface Water Treatment Rule" (LT2), increases monitoring and treatment requirements for water systems that are prone to outbreaks of Cryptosporidium, a waterborne pathogen. Consuming water with Cryptosporidium causes gastrointestinal illness which can be severe in people with weakened immune systems, such as infants or the elderly and could be fatal in people with severely compromised immune systems, such as cancer and AIDS patients. LT2 will improve public health by reducing illness due to Cryptosporidium and other harmful microorganisms in drinking water.

The rule requires that public water systems that are supplied by surface water sources monitor for Cryptosporidium. Those water systems that measure higher levels of Cryptosporidium or do not filter their water must provide additional protection by using options from a "microbial toolbox" of treatment and management processes, such as ultraviolet disinfection, and watershed control programs.

The rule also addresses risks of contamination in systems that store treated drinking water in open reservoirs, where water quality can be compromised by exposure to outdoor elements. The rule requires open reservoirs to either be covered or receive added treatment.

Stage 2 Disinfection Byproducts Rule (Stage 2 DBP)

The "Stage 2 Disinfection Byproducts Rule" (Stage 2 DBP), was developed to balance the benefits and risks posed by drinking water disinfection. While disinfection is commonly known as one of the major public health advances of the 20th century, it also creates harmful byproducts that are formed when disinfectants, such as chlorine, combine with naturally occurring materials in water.

The final rule targets water systems that have the greatest risk of high DBPs by using more stringent methods for determining compliance. Under the rule, water systems are required to find monitoring sites where higher levels of DBPs are likely to occur and use these new locations for compliance monitoring. If DBPs are found to exceed drinking water standards at any of these new monitoring locations, water systems must begin to take corrective action.

The final rules will be published in the Federal Register in January. Pre-publication copies and additional information can be found on the EPA web site at: http://www.epa.gov/safewater/disinfection

Legal Settlement Forces Agency to Protect Millions From Dangerous Parasites, Toxic Chemicals in Their Drinking Water

WASHINGTON (November 17, 2005) -- Public health advocates today reached an important agreement with the Environmental Protection Agency (EPA) ending years of delays in setting new safeguards against germs, parasites and toxic chemicals in drinking water across the country. As a result of the agreement, filed in U.S. District Court in Washington, D.C., EPA will adopt three new rules for municipal water systems by next year ensuring cleaner drinking water for all communities.

"Today's settlement requires EPA to strengthen health protections for the tap water that tens of millions of Americans drink and shower in every day," said Erik Olson, a senior attorney at the Natural Resources Defense Council (NRDC). "EPA will have to stop its foot-dragging and issue new, stricter safeguards for our tap water to protect us from dangerous parasites and toxic chemicals that can cause cancer, miscarriages and birth defects."

Represented by Earthjustice, NRDC and San Francisco Bay Area Physicians for Social Responsibility negotiated the agreement with EPA to avoid a protracted legal battle. It provides an enforceable schedule for the agency to develop rules reducing levels of Giardia, Cryptosporidium and certain toxic chemicals in public drinking water. (For a copy of the filed agreement, see http://www.nrdc.org/media/docs/051117.pdf.)

The agreement filed today requires EPA to adopt three new rules.

First, the agency must adopt, by December 15, a new rule requiring treatment and monitoring for suppliers drawing from surface waters. This is to prevent Cryptosporidium and other parasites from contaminating tap water. According to the Centers for Disease Control and Prevention, Cryptosporidium is one of the most common causes of waterborne disease in the United States. In 1993, high Cryptosporidium levels in Milwaukee's drinking water supply sickened more than 400,000 residents. More recently, several smaller outbreaks have sickened hundreds of people.

Second, EPA agreed to adopt a rule limiting the acceptable level of toxins created by the drinking water disinfection process itself. Disinfection is necessary to remove bacteria and pathogens from water supplies, but without proper precautions it leaves behind byproducts that can cause cancer, and, potentially, miscarriages and birth defects.

Finally, EPA agreed to publish a rule no later than August 2006 requiring systems using groundwater to disinfect it when necessary.

"Americans will finally have the health protections that Congress told EPA to provide years ago," said Earthjustice attorney Jennifer Chavez. "This agreement will guarantee that the agency sets the necessary standards for drinking water that will reduce illnesses and protect public health."

After several serious outbreaks of waterborne diseases in U.S. cities, Congress amended the Safe Drinking Water Act in 1996 to, as EPA has stated, "provide strengthened protections to ensure that American families have clean, safe tap water." The amendments required EPA to adopt regulations to reduce microbial pathogens within a specific time frame, but the deadline for a number of the final regulations has come and gone. For example, the final rule for treating surface water sources was supposed to have been completed by 2000.

EPA estimates its surface water treatment rule alone would prevent more than a million illnesses and as many as 141 deaths annually. The agency estimates its rule for toxic disinfection byproducts would prevent hundreds from dying from bladder cancer, would reduce the incidence of other cancers, and could cut the number of miscarriages from 4,700 to 1,100 a year.

"Every year that EPA delayed on these rules, Americans' health was at risk from exposure to these parasites and toxic chemicals," said Dr. Bob Gould, a physician and president of SF Bay Area Physicians for Social Responsibility. "We are very pleased to hear that the agency will finally begin adopting rules that will protect our drinking water supplies, and we hope the agency will make good on its promise this time."

Water Park Visitors Sue: No Day At The Beach

Patrice Walsh (Ontario County, NY) 10/18/05 - A day at the park turned out to be anything but for hundreds of Rochester-area families who were among the thousands sickened after visiting the spray park at Seneca Lake this summer.

Toni Lynn Van Bramer remembers telling her four-year-old son Joshua not to drink the water at the spray park when they visited in August. A week later, both of them were sick with gastrointestinal symptoms.

Van Bramer said, "It ruined the rest of the summer...it took us two and a half to three weeks before we felt normal...I was afraid to take him anywhere to make anybody else sick."

Tim Springer was the only one in his family who did not go to the spray park at the end of July, but he wound up the sickest.

He said, "One by one [my family] started getting sick."

Springer ended up spending five days in the hospital, missing two weeks of work and losing 12 pounds after his wife and three children passed the illness to him.

He said the pain was so intense that, "I was in the fetal position in the hospital--on morphine."

Class Action Lawsuit

Tim and Toni Lynn are among the hundreds from Rochester who reported illnesses linked to the spray park. They are part of a planned class-action lawsuit against the state.

Attorney Paul Nunes said, "We think the facts will show this is a simple case of negligence."

Officials at the state attorney general's office had no comment on the legal action.

The park was closed down after the illnesses were reported.

State health department workers found that the water was contaminated with a parasite, but have not determined how the contamination occurred.

New Regulations In The Works
Spencer said this case isn't about money, it's about accountability.
"There's no amount of money you could give me," he said, "I wouldn't want to go through that again."

The concern now is future safety of similar spray parks. The state health department is working on new regulations for spray parks including one that requires parks to use ultraviolet light technology to kill parasites in the water.

Those specific regulations will be released at the end of November.

Those named in the suit are asking for money for pain and suffering, lost time from work, and doctors' and hospital visits.

Only those who contact attorneys can be part of any class action case.
