List of cities with pharmaceuticals in water
thanks
I
At least one pharmaceutical was detected in tests of treated drinking water supplies for 24 major metropolitan areas, according to an Associated Press survey of 62 major water providers and data obtained from independent researchers.
Only 28 tested drinking water. Three of those said results were negative; Dallas says tests were conducted but results are not yet available. Thirty-four locations said no testing was conducted.
Test protocols varied widely. Some researchers looked only for one pharmaceutical or two; others looked for many.
Some water systems said tests had been negative, but the AP found independent research showing otherwise. Both prescription and non-prescription drugs were detected.
Because coffee and tobacco are so widely used, researchers say their byproducts are good indicators of the presence of pharmaceuticals. Thus, they routinely test for, and often find, both caffeine and nicotine’s metabolite cotinine more frequently than other drugs.
Here’s the list of metropolitan areas, with the number of pharmaceuticals detected and some examples of specific drugs that were found, or where tests were negative, not conducted or awaiting results:

Tainted drinking water kept under wrapsMany researchers fear public would misunderstand, overreact to disclosureBy MARTHA MENDOZAThe Associated Pressupdated 7:10 a.m. HT, Mon., March. 10, 2008When water providers find pharmaceuticals in drinking water, they rarely tell the public. When researchers make the same discoveries, they usually don’t identify the cities involved.There are plenty of reasons offered for the secrecy: concerns about national security, fears of panic, a feeling that the public will not understand — even confidentiality agreements.“That’s a really sensitive subject,” said Elaine Archibald, executive director of California Urban Water Agencies, an 11-member organization comprised of the largest water providers in California.She said many customers “don’t know how to interpret the information. They hear something has been detected in source water and drinking water, and that’s cause for alarm — just because it’s there.”As The Associated Press documented in a five-month investigation, drinking water provided to at least 41 million people living in 24 major metropolitan areas has tested positive for trace amounts of pharmaceuticals.Reports don't reveal allMost Americans probably think they have a good idea of what’s being detected in their water. Federal law requires water providers to distribute annual “consumer confidence reports” that reveal levels of regulated contaminants. Providers are not, however, required to tell people if they find a contaminant that is not on a U.S. Environmental Protection Agency list. And there are no pharmaceuticals on the EPA list.In Philadelphia, the water department has not informed its 1.5 million users that traces of 56 pharmaceuticals or their byproducts — like the active ingredients in drugs to treat depression, anxiety, high cholesterol, fever and pain — have been detected in the drinking water, and that 63 pharmaceuticals or byproducts had been found in the city’s source watersheds.Initially balking at the AP’s request to provide test results, Philadelphia Water Department spokeswoman Laura Copeland said, “It would be irresponsible to communicate to the public about this issue, as doing so would only generate questions that scientific research has not yet answered. We don’t want to create the perception where people would be alarmed.”New York City water officials declined repeated requests for an interview and waited more than three months before participating in an AP survey, supplying information only after being informed that every other major city in the nation had cooperated.The AP learned that the New York state health department and the U.S. Geological Survey detected heart medicine, infection fighters, estrogen, anti-convulsants, a mood stabilizer and the active ingredient in an anti-anxiety medication in the city’s watershed upstate. And the city’s Department of Environmental Protection ultimately said that it does not test its downstate drinking water.Officials in Arlington, Texas, said pharmaceuticals had been detected in source water but wouldn’t say which ones or in what amounts, citing security concerns. Julie Hunt, director of water utilities, said to provide the public with information regarding “which, if any, pharmaceuticals or emerging compounds make it through the treatment process can assist someone who wishes to cause harm through the water supply.”Mayor Robert Cluck later said a trace amount of one pharmaceutical had survived the treatment process and had been detected in drinking water. He declined to name the drug, saying identifying it could cause a terrorist to intentionally release more of it, causing significant harm to residents.“I don’t want to take that chance,” Cluck said. “There is no public hazard and I don’t want to create one.”Ron Rhodes, water treatment plant supervisor in Emporia, Kan., explained why he wouldn’t disclose whether his community’s source water or drinking water had been tested for pharmaceuticals. “Well, it’s because of 9/11. We want everybody to guess.”How, Rhodes was asked, could it endanger anyone to know if Emporia’s water has been screened for traces of pharmaceutical compounds?“We’re not putting out more information than we have to put out,” said Rhodes. “How about that?”Milwaukee’s water department is an anomaly, posting on its Web site an 11-page detailed drinking water quality report that includes test results for 450 unregulated contaminants, including pharmaceuticals. While they found minute concentrations of cotinine, a nicotine derivative, they didn’t detect hundreds of other contaminants including estrogens and other hormones, acetaminophen and ibuprofen.When asked what power the EPA had to require public disclosure when pharmaceutical contamination is discovered in a water provider’s supplies, Benjamin H. Grumbles, the agency’s assistant administrator for water, said, “We work very closely with utilities across the country and we encourage them to share with their community information they find out about their source water.”But there’s no such requirement if the detected contaminant is not regulated under the Safe Drinking Water Act, he said in response to a question.'More work to do'Grumbles was asked how he thought water providers have been responding to the EPA’s “encouragement.”“I think we have more work to do,” he said.Several hours after the interview, Grumbles issued a statement: “As head of the National Water Program, I will do everything in my authority to make certain that public water suppliers inform their consumers if they detect pharmaceuticals in the drinking water.”It’s not just the water departments that have failed to disclose such information.The AP spoke with many scientists, federally funded researchers, university professors and private drinking water experts who have detected pharmaceuticals in drinking water, but would not say where they had obtained their samples.Archibald said her organization joined an American Water Works Association Research Foundation study with the understanding that secrecy would be assured.“We agreed ahead of time that no specific agency would be mentioned in terms of which place had detections,” Archibald said. She insisted that even she didn’t have the test results. “It’s all being held very carefully. Water agencies were assigned numbers so none of us would even know what was detected in each other’s water.”Robert Renner, the foundation’s executive director, said AWWARF study participants are routinely promised anonymity. “Being involved in a study, they don’t want this information blown out all over,” he said.Fearing public will overreactCiting confidentiality agreements, he declined to name the 20 different drinking water treatment plants around the U.S. where pharmaceuticals have been detected in water heading to more than 10 million people.“It’s a hard topic to talk about without creating fear in the general public,” Renner said.Some said those fears could lead to much larger problems than the actual contamination.Doctors “don’t want people to be afraid to take their medicine because of environmental concerns,” said Virginia Cunningham, an environmental executive for drug maker GlaxoSmithKline PLC.Utilities also generally only allow scientists to test their water if they ensure confidentiality. In order for research to progress, scientists “need the confidence of utilities and other public/private stakeholders to allow us access to waters which we can study without any negative implications for those stakeholders,” said Howard Weinberg, an environmental chemist at University of North Carolina. “Without this confidence, such research could not be undertaken.”John Vargo, program manager at the University of Iowa’s University Hygienic Laboratory, said he found traces of pharmaceuticals in the finished drinking water of several major Midwestern cities but, under terms of those contracts, he could not disclose their identity.Peter Rogers, Harvard University professor of environmental engineering, said improvements in detection techniques could help fuel fears among the general public.“We’re chasing this down to molecular-sized measurements, so the more you look, the more you find,” said Rogers. “I think the government and utilities are quite right to be very skittish about telling people their results. People will claim it is causing all sorts of problems. If I were a water utility, I would stop those measurements right away because if you measure something, it will get out, and people will overreact. I can just imagine a whole slew of lawsuits.”© 2008 The Associated Press. All rights reserved.
