Public health goal establishes a long-term objective for the reduction of arsenic in California's drinking water. Arsenic is one of the most toxic substances commonly found in drinking water, and it occurs naturally in many parts of the world, including California.

OEHHA has issued two fish advisories concerning elevated levels of mercury in certain fish from five reservoirs and portions of the Bear and South Yuba rivers and Deer Creek in the Northern Sierra Nevada foothills, and from Black Butte, Stony Gorge and East Park reservoirs.  The advisories contain guidelines for consumption of bass, channel catfish, trout and other fish species.

OEHHA conducted an exhaustive analysis of all available scientific studies on the health effects of arsenic. The proposed PHG of 4 parts per trillion is based upon studies of hundreds of thousands of patients in Taiwan, Chile and Argentina with lung and bladder cancers associated with elevated levels of arsenic in drinking water.
