Many American’s use prescription medications. A 2004 government report stated that almost half of the American population takes at least one prescription medication. Many others take more than one. Anti-depressant medication, hormonal medication, antibiotics and others are turning up, in an unlikely place, in our drinking water. The municipal tap water that flows from our faucets contains residues of prescription drugs.

Here are some of the key test results:

• Officials in Philadelphia, Pennsylvania, 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 city’s watersheds.

• Anti-epileptic and anti-anxiety medications were detected in a portion of the treated drinking water for 18.5 million people in Southern California.

• Researchers at the U.S. Geological Survey analyzed a Passaic Valley Water Commission drinking water treatment plant, which serves 850,000 people in Northern New Jersey, and found a metabolized angina medicine and the mood-stabilizing carbamazepine in drinking water.

• A sex hormone was detected in the drinking water of San Francisco, California.

• The drinking water for Washington, D.C., and surrounding areas tested positive for six pharmaceuticals.

The situation is undoubtedly worse than suggested by the positive test results in the major population centers. (full story)
