Is there PFAS in Nj American Water - Washington/oxford water?
Yes. EPA's final UCMR 5 results show Nj American Water - Washington/oxford averaged 7.1 ppt of PFOS at its worst sampling point, 1.8 times the EPA limit of 4 ppt.
Nj American Water - Washington/oxford is a public water system drawing on groundwater, based in Cherry Hill, New Jersey, serving about 10,719 people, including Oxford, Port Murray, Washington, Broadway. Under EPA's Fifth Unregulated Contaminant Monitoring Rule it was tested for 29 PFAS and lithium 12 times across 6 sampling points between Feb 2023 and Aug 2025.
Every PFAS detected
| PFAS | Detected | Highest | Worst point avg | EPA limit |

Lithium, tested in the same program: highest 18.7 ppb, detected in 4 of 12 samples. EPA's health-based screening level is 10 ppb.
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. See the best filters for PFAS and how PFAS removal works.
