On December 31st, the California Environmental Protection Agency’s Office of Environmental Health Hazard Assessment (OEHHA) released a revised draft Public Health Goal (PHG) that represents a stricter limit than what was previously proposed for hexavalent chromium, also known as Chromium VI, in drinking water. The PHG is intended to be used by the California Department of Public Health as a guideline when setting reasonable maximum contamination level standards for drinking water.

The original goal of .06 parts per billion (ppb) was of significant concern to manufacturers and water purveyors in the State. The new goal of .02 ppb is even stricter.

OEHHA says that the change is due to consideration of early-in-life exposures for cancer potency. Chromium VI was made famous by the “Erin Brockovich” film more than a decade ago.

The draft document and other related information is posted on the OEHHA website at: www.oehha.ca.gov/water/phg/chrom123110.html. They will be accepting public comments until 5PM on January 31, 2011.
