How to read these numbers

This page lists all 245 community water systems in New Jersey with UCMR 5 PFAS results, across 21 counties. We compare each one with our 0.5 ng/L PFAS-4 benchmark and with the 4.0 ng/L federal MCL for PFOA and PFOS, which applies from April 2029. UCMR 5 results do not indicate compliance or noncompliance with the PFAS drinking water standards. The samples come from entry points, with 3 to 4 ng/L reporting limits. New Jersey also enforces its own PFAS MCLs under N.J.A.C. 7:10 (table above). State agency: New Jersey Department of Environmental Protection (NJDEP), Bureau of Safe Drinking Water. State monitoring: quarterly compliance monitoring since 2021. Regulation data retrieved September 19, 2026.
