The California Environmental Protection Agency released a draft report in July 2021 which would set a science-based safe level—called a public health goal—of 0.007 part per trillion (ppt) for perfluorooctanoic acid (PFOA) and 1 ppt for perfluorooctanesulfonic acid (PFOS) in drinking water. The proposed public health goals are much lower than those set by the EPA on a federal level in 2016 (70 ppt for PFOA and PFOS, individually or combined).
