California health officials propose to lower the limits of a heavy-metal often found in drinking water. Health Care Reporter Pauline Bartolone has more from Sacramento.

The California Department of Public Health proposes a regulation that would reduce the allowable level of ‘chromium-6’ in water to five times less than it is now. 

Chromium-six is carcinogenic. The substance is both naturally occurring, and leaks into the water supply from industrial hazardous waste areas.

Two major environmental groups have filed suit against the California State Department of Public Health for what they call a failure by the state to set rules for the safe amount of a toxic chemical in drinking water. Hexavalent chromium, also known as chromium-6, gained widespread attention as the chemical that sickened residents in the film Erin Brockovich.
