PFAS — EPA UCMR5 (2023–2025)
1 PFAS compound above EPA limits in City of Huntington Beach, CA
The EPA finalized the first-ever federal drinking-water limits for six PFAS compounds in April 2024. These numbers come straight from EPA's UCMR5 lab dataset — every U.S. system serving more than 3,300 people tested every PFAS sample at an entry point to its distribution system. PFAS not listed below were either tested and not detected, or not yet sampled.
PFOS (Perfluorooctane sulfonic acid)
● Over EPA limit (1.5×)below national p90 (19.900000000000006 ng/L across detecting U.S. systems)
