Known ‘Probable Carcinogen’ Found in Drinking Water of 31 Cities Across U.S.

December 20, 2010

(ChattahBox U.S. News)—Do you remember the chemical that was present in the drinking water in the movie “Erin Brockovich,” causing the townspeople to contract various illnesses? It was hexavalent chromium, and it could be coming to a faucet near you.

The Environmental Working Group recently analyzed the drinking water in 35 U.S. cities and found hexavalent chromium in 31 of them, the Washington Post reports. The chemical was declared a “probable carcinogen” in 2009, and the EPA is currently considering whether it should set a limit for how much of the chemical can legally be present in drinking water.

California has already proposed setting a limit of the amount of the chemical that can be present in its drinking water, the Post notes. Hexavalent chromium was used as an industrial chemical for years, and can leach into groundwater and make its way into the water supply.
