A new study released by the Associated Press found there are small amounts of prescription drugs in the state?s drinking water.

According to the study, New Jersey is not alone. The study also found drinking water supplied to 41 million Americans contains small amounts of drugs. The study found prescription drugs and over-the-counter medicines in water systems.

United Water says its water is cleansed at treatment plants, but those treatments don?t remove all drug residue.

?It?s not something that is regulated and that we test for in normal testing procedures,? Sonja Clark, of United Water, says. ?However, it is something we are going to look into, but EPA and DEP do not require us to test for these products.?

Clark adds that the water supply is safe and the concentrations of pharmaceuticals are far below the levels of a medical dose.

Meanwhile, 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. They found a metabolized angina medicine and a mood-stabilizing drug in drinking water.
