Unformatted text preview: By Jeff Donn, Martha Mendoza and Justin Pritchard Associated Press Writers March 9, 2008 Editor's note: First of a three-part series. A vast array of pharmaceuticals including antibiotics, anti-convulsants, mood stabilizers and sex hormones have been found in the drinking water supplies of at least 41 million Americans, an Associated Press investigation shows. To be sure, the concentrations of these pharmaceuticals are tiny, measured in quantities of parts per billion or trillion, far below the levels of a medical dose. Also, utilities insist their water is safe. But the presence of so many prescription drugs and over-the-counter medicines like acetaminophen and ibuprofen in so much of our drinking water is heightening worries among scientists of long-term consequences to human health. From California to New Jersey In the course of a five-month inquiry, the AP discovered that drugs have been detected in the drinking water supplies of 24 major metropolitan areas from Southern California to Northern New Jersey, from Detroit to Louisville, Ky. Water providers rarely disclose results of pharmaceutical screenings, unless pressed, the AP found. For example, the head of a group representing major California suppliers said the public doesnt know how to interpret the information and might be unduly alarmed. How do the drugs get into the water? People take pills. Their bodies absorb some of the medication, but the rest of it passes through and is flushed down the toilet. The wastewater is treated before it is discharged into reservoirs, rivers or lakes. Then, some of the water is cleansed again at drinking water treatment plants and piped to consumers. But most treatments do not remove all drug residue. And while researchers do not yet understand the exact risks from decades of persistent exposure to random combinations of low levels of pharmaceuticals, recent studies which have gone virtually unnoticed by the general public have found alarming effects on human cells and wildlife. We recognize it is a growing concern and were taking it very seriously, said Benjamin H. Grumbles, assistant administrator for water at the U.S. Environmental Protection Agency. Members of the AP National Investigative Team reviewed hundreds of scientific reports, analyzed federal drinking water databases, visited environmental study sites and treatment plants and interviewed more than 230 officials, academics and scientists. They also surveyed the nations 50 largest cities and a dozen other major water providers, as well as smaller community water providers in all 50 states. Key findings Here are some of the key test results obtained by the AP: Officials in Philadelphia said testing there discovered 56 pharmaceuticals or byproducts in treated drinking water, including medicines for pain, infection, high cholesterol, asthma, epilepsy, mental illness and heart problems. Sixty-three pharmaceuticals or byproducts were found in the citys watersheds. pharmaceuticals or byproducts were found in the citys watersheds....
