NEW YORK, NY April 04, 2008 —The city's Department of Environmental Protection says trace amounts of pharmaceuticals in New York's water supply do not pose significant health risks.

At a City Council hearing, Deputy Commissioner Paul Rush said, among other drugs, New York tap water contains very minute amounts of caffeine and ibuprofen.

RUSH: A person would have to drink 1 million glasses of water to get the dose of one over-the-counter ibuprofen tablet or the caffeine in one cup of coffee.

REPORTER: Committee Chairman James Gennaro says the effects of long-term exposure to low levels of pharmaceuticals are still unknown. He's calling for regular tests of the city's drinking water.
