The Department of Environmental Protection in New York City has detected trace levels of prescription drugs and personal care products in the city’s drinking water supply. The Department of Environmental Protection tested the drinking water for 72 compounds, including antibiotics and prescription drugs. The tests found 14 drugs and personal care products at least once. None of those substances, however, was detected at dangerous levels. “For most of these detected compounds, a person would have to drink at least tens of thousands of glasses of water a day to get one effective dose of the substance or to meet a toxicity threshold,” said the Department of Environmental Protection in a statement. There is still concern that the drinking water could be dangerous, however, and renewed calls for regular “take back” days that will safely dispose of unwanted or unused prescription drugs.
