SACRAMENTO, Calif. – California environmental health officials are recommending stricter limits on a carcinogen in drinking water whose dangers became more widely known after the 2000 film "Erin Brockovich."
Scientists with the state's Office of Environmental Health Hazard Assessment said Friday water systems should have no more than 0.02 parts per billion of hexavalent chromium. That's down from their 2009 recommendation of 0.06 parts per billion.
