PFOA and PFOS Notification Levels: In May 2016, the United States Environmental Protection Agency (U.S.EPA) issued a lifetime health advisory for PFOS and PFOA for drinking water, advising municipalities that they should notify their customers of the presence of levels over 70 parts per trillion in community water supplies. U.S.EPA recommended that customer notifications include information on the increased risk to health, especially for susceptible populations. In June 2018, California’s Office of Environmental Health Hazard Assessment (OEHHA) recommended interim notification levels for PFOA (based on liver toxicity, as well as cancer risks), and for PFOS (based on immunotoxicity). OEHHA made these recommendations following its review of currently available health-based advisories and standards and supporting documentation. After independent review of the available information on the risks, the Water Board Division of Drinking Water (DDW)established notification levels for PFOS and PFOA (13 parts per trillion for PFOS and 14 parts per trillion for PFOA), as well as a single health advisory response level which offers a margin of protection for all persons throughout their life from adverse health effects resulting from exposure to PFOA and PFOS in drinking water. When possible, DDW recommends removing the source from service or providing treatment when the concentration exceeds a notification level. DDW recommends removing the source from service when the concentration level cannot be reduced below the response level of 70 ppt.
