Important News: Chromium-6 Is Widespread in US Tap Water

Cancer-causing chemical found in 89 percent of cities sampled!

Laboratory tests commissioned by Environmental Working Group (EWG) have detected hexavalent chromium, the carcinogenic “Erin Brockovich chemical,” in tap water from 31 of 35 American cities. The highest levels were in Norman, Okla.; Honolulu, Hawaii; and Riverside, Calif. In all, water samples from 25 cities contained the toxic metal at concentrations above the safe maximum recently proposed by California regulators.

The National Toxicology Program has concluded that hexavalent chromium (also called chromium-6) in drinking water shows “clear evidence of carcinogenic activity” in laboratory animals, increasing the risk of gastrointestinal tumors. In September 2010, a draft toxicological review by the U.S. Environmental Protection Agency (EPA) similarly found that hexavalent chromium in tap water is “likely to be carcinogenic to humans.”

In 2009, California officials proposed setting a “public health goal” for hexavalent chromium in drinking water of 0.06 parts per billion (ppb) to reduce cancer risk. This was the first step toward establishing a statewide enforceable limit. Despite mounting evidence of its toxic effects, the EPA has not set a legal limit for hexavalent chromium in tap water nationally and does not require water utilities to test for it. In 25 cities where EWG’s testing detected chromium-6 — in the first publicly available national survey for the contaminant — it was found in concentrations exceeding California’s proposed maximum, in one case at a level more than 200 times higher.

At least 74 million Americans in 42 states drink chromium-polluted tap water, much of it likely in the cancer-causing hexavalent form. Given the scope of exposure and the magnitude of the potential risk, EWG believes the EPA should move expeditiously to establish a legal limit for chromium-6 and require public water suppliers to test for it.
