Hexavalent Chromium found in drinking water

Hexavalent chromium, also known as chromium-6, first gained notoriety when the film "Erin Brockovich" highlighted the plight of Hinkley, California, where the groundwater had been contaminated. Now the first publicly available national survey on the contaminant from Environmental Working Group reveals that Hinkley isn't alone.

Laboratory tests commissioned by EWG have discovered that the chemical is present in the tap water of 31 out of 35 U.S. cities tested, or 89 percent. Norman, Oklahoma; Honolulu, Hawaii; and Riverside, California returned the highest levels of contamination.

According to EWG, the National Toxicology Program concludes that hexavalent chromium drinking water contamination shows "clear evidence of carcinogenic activity" in laboratory animals, and that a recent review by the EPA found its presence in tap water "likely to be carcinogenic to humans."

Although in 2009 California began setting in motion proposed limits for the amount of the chemical allowed in tap water, the EPA has yet to set a legal national limit and doesn't require utilities to test for it.

Thats very disturbing, CCA wood which contains hexavalent chromium is also all over the place. It was banned 5 years ago however it still exists as decks, children's playgrounds ect. There is no safe disposal of this wood and the toxic arsenic and chromium leach into soil and water and stays there. The inorganic arsenic enters the food chain, im not sure whether the hexavalent chromium does as well.
