Per- and Polyfluoroalkyl Substances (PFAS)
Welcome to the Water Boards' Per- and Polyfluoroalkyl Substances (PFAS) webpage
This webpage provides a general background on PFAS, information on where PFAS data is being collected across the state, announcements for current Water Board events, links to past Water Board events, and links to other state entities implementing efforts on PFAS.
The Water Boards' PFAS Team is a group of technical and support staff within the State Water Board Divisions of Drinking Water and Water Quality, and the Regional Water Quality Control Boards. A primary objective of the Team is to provide information and data that is easily accessible and understandable.
This webpage provides a central point where information is communicated to the public regarding PFAS investigative actions conducted, and the results from those actions.
