What is PFAS?

PFAS — “forever chemicals” — are synthetic compounds that accumulate in the body and are linked to cancer, liver damage and immune effects. In 2024 the EPA set enforceable limits of 4 parts per trillion each for PFOA and PFOS. These are the only nationwide PFAS measurements, from the EPA’s UCMR-5 program.
