Calif. Takes First Moves to Limit ‘Erin Brockovich’ Chemical

California has emerged as the first state to advance limits on hexavalent chromium in drinking water, a contaminant linked to cancer first made famous by Erin Brockovich’s advocacy efforts.

The California Water Resources Control Board’s Drinking Water Program on Monday unveiled a proposal to set a “maximum contaminant level” (MCL) of 10 parts per billion, or ppb, in water.
