A Public Health Goal (PHG) is the level of a drinking water contaminant at which adverse health effects are not expected to occur from a lifetime of exposure. The technical support document presents the scientific information available on the toxicity of perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) and the calculation of the proposed PHGs.

OEHHA performs major risk assessment and hazard evaluation activities relating to chemical contaminants in drinking water. These activities include developing health advisories, Public Health Goals for chemical substances in drinking water, Notification Levels, and providing toxicological assistance for chemical monitoring activities for the drinking water supply. The program also provides education to the public and other governmental agencies on drinking water contamination and drinking water regulatory standards development.

OEHHA announces the release of its final Human Right to Water Framework and Data Tool (CalHRTW 1.0)—comprised of an interactive web tool and report, Achieving the Human Right to Water in California: An Assessment of the State’s Community Water Systems.
The updated Public Health Goal of 0.003 parts per billion (ppb) is based on carcinogenicity and is set at a level of risk of one additional cancer case per one million persons exposed over a 70-year lifetime.
The draft technical support document presents the scientific information available on the toxicity of 1,2-dibromo-3-chloropropane (DBCP) and the calculation of the updated Public Health Goal (PHG). The proposed updated PHG of 0.003 parts per billion (ppb) is based on carcinogenicity and is set at a level of risk of one additional cancer case per one million persons exposed over a 70-year lifetime.
