New Jersey Establishes PFAS Maximum Contaminant Levels for Drinking Water

New Jersey has established enforceable Maximum Contaminant Levels (MCLs) and Ground Water Quality Standards (GWQS) for three PFAS compounds in drinking water: PFOA (0.014 μg/L), PFOS (0.013 μg/L), and PFNA (0.013 μg/L). The state also has interim Ground Water Quality Criteria for ClPFPECAs (0.002 μg/L), PFPE-DCAs (0.0021 μg/L), and HFPO-DA/GenX (0.02 μg/L).
