Is there PFAS in Delray Beach Public Water System water?

Yes. EPA's final UCMR 5 results show Delray Beach Public Water System averaged 28.7 ppt of PFOS at its worst sampling point, 7.2 times the EPA limit of 4 ppt.

Delray Beach Public Water System is a public water system drawing on groundwater, based in Delray Beach, Florida, serving about 69,754 people. Under EPA's Fifth Unregulated Contaminant Monitoring Rule it was tested for 29 PFAS and lithium 1 times across 1 sampling point between Apr 2023 and Oct 2023.

Every PFAS detected

Not detected: PFTA, NMeFOSAA, NEtFOSAA, PFTrDA, PFHpS, PFUnA, PFPeS, PFEESA, PFMBA, PFMPA, 8:2 FTS, 4:2 FTS, 6:2 FTS, HFPO-DA, 11Cl-PF3OUdS, PFDoA, PFNA, PFDA, NFDHA, 9Cl-PF3ONS, ADONA.

Lithium, tested in the same program: not detected.

What the EPA limits mean here

In April 2024 EPA set enforceable limits of 4 ppt for PFOA and PFOS, 10 ppt each for PFHxS, PFNA and GenX, and a hazard index of 1 for mixtures. Utilities were given until 2029 to comply. In May 2026 EPA proposed keeping only the PFOA and PFOS limits and moving that deadline to 2031. Until that proposal is final, the 2024 limits stand.

Compliance is judged on a running annual average at each entry point, so we show the average at this system's worst sampling point next to its single highest result. UCMR 5 results do not by themselves put a utility in or out of compliance.

What you can do at home

Two routes work for PFAS. For drinking and cooking water only, a reverse osmosis system certified to NSF/ANSI 58 with a PFOA/PFOS reduction claim is the cheapest proven option. To treat every tap and shower, a whole-house carbon system with enough contact time works, but check that the maker has PFAS test data, not just a marketing claim.
