Public health goals (PHGs) are concentrations of drinking water contaminants that pose no significant health risk if consumed over a lifetime. The Office of Environmental Health Hazard Assessment (OEHHA) establishes PHGs, which are used as the health basis for the development of California's primary drinking water standards. OEHHA also reviews and updates existing PHGs. This public notice provides an update on PHG reviews in progress and announces the initiation of reviews for three chemicals: chlorobenzene, 1,1-dichloroethane, and trichloroethylene.
