New limits for 8 organics in tapwater.

New limits for 8 organics in tapwater

The Environmental Protection Agency (EPA) has just announcedfinal standards for the eight most prevalent volatile organic-chemical pollutants in tapwater. The new limits, which go into effect Dec. 31, 1988, involve benzene and vinyl chloride-- both known human carcinogens--and several probable or possible carcinogens, such as carbon tetrachloride and trichloroethylene. While environmentalists had pushed for limits on these chemicals, many, like Jacqueline Warren of the Natural Resources Defense Council in New York City, are not satisfied with the standards. She says the vinyl chloride limit of 2 parts per billion, for example, is about 20 times higher than what EPA has suggested can be removed by activated carbon filtering-- an available technology.
