This month the State Water Resources Control Board posted the first results of testing for perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) for nearly 600 drinking water supply wells. This testing was performed as part of a comprehensive effort to assess the presence of harmful per- and polyfluoroalkyl substances (PFAS)—coined “forever chemicals—in water systems and groundwater statewide.

California's Phased Investigation Approach to PFAS
Last month the Division of Drinking Water and the Division of Water Quality announced the State Water Resources Control Board’s phased investigation approach to PFAS. It is the intention of the Board to begin the investigation by collecting PFAS detection data at 31 airports and 252 municipal solid waste landfills. These facilities have the potential to impact over 1,320 surrounding drinking water wells and drinking water sources.
