Yes. EPA's final UCMR 5 results show Gordons Corner Water CO averaged 5.9 ppt of PFOA at its worst sampling point, 1.5 times the EPA limit of 4 ppt.
Also detected, no federal limit: PFHxA, PFPeA.
Gordons Corner Water CO is a public water system drawing on surface water, based in Marlboro, New Jersey, serving about 46,196 people, including Englishtown, Marlboro. Under EPA's Fifth Unregulated Contaminant Monitoring Rule it was tested for 29 PFAS and lithium 12 times across 4 sampling points between Dec 2023 and Sep 2024.
| PFAS | Detected | Highest | Worst point avg | EPA limit |
|---|---|---|---|---|
| PFHxA Perfluorohexanoic acid |
5 of 12 | 11.4 ppt | 3.9 ppt | none |
| PFOA Perfluorooctanoic acid |
6 of 12 | 8.2 ppt | 5.9 ppt | 4 ppt |
| PFPeA Perfluoropentanoic acid |
4 of 12 | 4.9 ppt | 3.4 ppt | none |
Not detected: PFMBA, PFUnA, 11Cl-PF3OUdS, 9Cl-PF3ONS, HFPO-DA, 6:2 FTS, 4:2 FTS, 8:2 FTS, PFPeS, PFEESA, NFDHA, ADONA, PFHpS, PFMPA, NMeFOSAA, PFBA, PFDoA, PFTA, NEtFOSAA, PFBS, PFOS, PFHxS, PFDA, PFNA, PFHpA, PFTrDA.
Lithium, tested in the same program: not detected.
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.
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.
