On January 14, 2023, Pennsylvania adopted a final rule establishing a Maximum Contaminant Level (MCL) for perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) in drinking water. The final rule establishes an MCL of 14 parts per trillion (ppt) for PFOA and 18 ppt for PFOS. Pennsylvania joins a growing list of states to adopt MCLs. By comparison, New Jersey has adopted slightly lower MCLs for PFOA (13 ppt) and PFOS (14 ppt). Pennsylvania’s MCLs for PFOA and PFOS apply to all community, nontransient, noncommunity, and bottled, vended retail, and bulk water systems. Read more.
