Chromium 6 Impact

CR6In our previous post on the CA Chromium 6 proposal, we shared that CDPH has officially proposed a Maximum Contaminant Level of .01-milligrams per liter. The proposal is open for public comment, and the public is beginning to do just that.

The Board unanimously supported a resolution urging the state urging the state to rethink plans to further limit Chromium 6. The metal is found naturally in the Coachella Valley’s drinking water as a result of erosion of a type of serpentine rock that’s found along the San Andreas Fault. Supervisor John Benoit said: “It certainly is a noble effort to make sure we have the cleanest drinking water available. But this is a standard that is not applicable anywhere else in the nation.”


Benoit also said the California Department of Public Health should undertake a more thorough cost-benefit analysis before moving toward implementation. State health officials have estimated the average ratepayer would only see a $64 spike in water costs — a figure that “severely underestimates the cost impacts to Coachella Valley” residents. And Riverside County is not the only county that would face rate increases if the proposed MCL becomes mandatory.
