WASHINGTON - A wide range of pharmaceuticals that include antibiotics, sex hormones, and drugs used to treat epilepsy and depression, contaminate drinking water supplies of at least 41 million Americans, according to a 5-month investigation by the Associated Press National Investigation Team released today.

“Environmental Working Group's (EWG) studies show that tap water across the U.S. is contaminated with many industrial chemicals, and now we know that millions of Americans are also drinking low-level mixtures of pharmaceuticals with every glass of water,” said Jane Houlihan, EWG Vice President for Research. “The health effect of this cocktail of chemicals and drugs hasn't been studied, but we are concerned about risks for infants and others who are vulnerable. Once again, the press is doing EPA‘s work when it comes to informing the public about contaminated tap water.“

Environmental Working Group analysis shows that of the top 200 drugs in the U.S., 13 percent list serious side effects at levels less than 100 parts-per-billion (ppb) in human blood, with some causing potential health risks in the parts-per-trillion range. EWG calls on EPA to take swift action to set standards for pollutants in tap water that will protect the health of Americans nationwide, including children and others most vulnerable to health risks from these exposures.
