Hexavalent chromium, also referred to as chromium-6, 1st gained notoriety when the movie “Erin Brockovich” highlighted the plight of Hinkley, California, wherever the groundwater had been contaminated.

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