Yes, even in the US we have to think about what we are doing to ourselves, and our drinking sources........
"These emerging contaminants were hard to detect without the finely tuned equipment developed recently. The first nationwide survey, conducted in 1999 and 2000, found hormones in about 37 percent of the streams surveyed and caffeine in more than half.
The only testing in the Potomac, done in Washington in 2002, found low levels of caffeine, plus the insecticide DEET and chemicals produced when a body breaks down nicotine. There were also a few suspected endocrine disruptors, including chemicals found in hand soap and household cleaners.
As of now, little is done to test for these chemicals — either in river water or in drinking water. The U.S. Environmental Protection Agency has not set standards, saying more research is needed to determine which contaminants are harmful and what levels are unsafe."
