California may become the first state to limit the amount of chromium VI in drinking water. The proposed safe level of the carcinogen would be .06 parts per billion. As LEO reports, Louisville does not meet that standard, even though the water will soon be in line with new federal regulations.

Louisville ranks 22nd out of 25 communities whose drinking water contains unsafe levels of hexavalent chromium, aka chromium VI (aka a major plot element in “Erin Brockovich“).

Today marks the release of a new study conducted by The Environmental Working Group (EWG), marking the first time such a study involving tap water contamination of chromium six has been made public.
