Latest News: California Sets the Lowest Notification Levels for PFAS in the Country

The California State Water Resources Control Board, Division of Drinking Water (DDW), has accepted the Office of Environmental Health Hazard Assessment’s (OEHHA) recent recommendation on new lower Notification Levels (NLs) for PFOA and for PFOS. On August 23, 2019, the DDW announced it established notification levels for PFOS and PFOA at 6.5 parts per trillion for PFOS and 5.1 parts per trillion for PFOA. These new levels are set at the lowest levels at which they can be reliably detected in drinking water using currently available analytical detection methods.
