Perfluoroalkyl and polyfluoroalkyl substances (PFASs) are a broad class of fluorine-rich specialty chemicals. More than 4,700 PFASs are used in consumer, commercial and industrial applications. Well-studied members of the perfluoroalkyl family, including perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA), have been shown to be highly toxic. Use is shifting to alternatives to PFOS and PFOA, including shorter-chain perfluoroalkyl chemicals and polyfluoroalkyl chemicals. This report compiled existing Bay PFAS data collected by the RMP and other organizations, reviewed the classification of PFASs detected in the Bay using the RMP’s tiered risk framework that guides monitoring and management actions on emerging contaminants, and recommended a monitoring strategy for the RMP for PFASs. As a result of summary information presented in the latest Pulse of the Bay, the San Jose Mercury News published an article based on an RMP study of pesticide movement through Bay Area wastewater treatment plants. Fipronil is an insecticide that is of moderate concern for the Bay because levels in sediment are in the range of toxicity thresholds for freshwater aquatic life...
