Recommendations for safely eating fish from Ventura County's Lake Piru were developed by OEHHA for three fish species based on levels of mercury measured in fish sampled from Lake Piru.
Press Releases
OEHHA has adopted an updated public health goal (PHG) of 1 part per billion (ppb) for perchlorate in drinking water. This PHG updates the 2004 perchlorate value of 6 ppb. Perchlorate is known to block the thyroid’s ability to take in and process iodide, which is a nutrient essential to brain development, growth, heart function, and other systems.
The study is the first to consider the effects on people of long-term exposure to ultrafine particles and analyzed data from more than 100,000 middle-aged women whose health status was followed from 2000 through 2007.
Recommendations for the safe consumption of several fish species based on levels of methylmercury, the type of mercury that can be toxic to humans. Depending on the exposure level, methylmercury can harm the brain and nervous system of people, especially in fetuses and children as they grow.
The tool uses data on 12 types of pollution and environmental factors and seven population characteristics and socioeconomic factors to create scores for each of the state’s 8,000 census tracts.
The draft guidance manual summarizes three Technical Support Documents focused on non-cancer risk, cancer risk, and exposure assessment.

The fish advisory for Clear Lake provides information on fish and shellfish important to Tribal members and other fish consumers. Newly added species of interest to Tribal members include threadfin shad, prickly sculpin, mosquitofish, inland silversides, winged floater mussels, and Asian clams.
Health advisory recommendations for each of the fish species are based on levels of methylmercury and polychlorinated biphenyls (PCBs) in fish sampled from Little Rock Reservoir.
Fish Advisory For Vasona Lake and Camden Ponds: Trout Safe to Eat Daily: But Avoid Carp and Goldfish
Vasona Lake and Camden Ponds are part of the 150-acre Vasona Lake County Park in Los Gatos. The largest pond is stocked with rainbow trout. The advisory is based on data from the State Water Resources Control Board’s Surface Water Ambient Monitoring Program and the San Francisco Bay Regional Water Quality Control Board.
