Yes, at low levels. 1 PFAS was detected, all below EPA's 2024 limits.
Also detected, no federal limit: 6:2 FTS.
West Wilkes Wtr Association INC is a public water system drawing on surface water, based in Millers Creek, North Carolina, serving about 12,573 people, including Ferguson, Millers Creek, North Wilkesboro, Purlear, Wilkesboro. Under EPA's Fifth Unregulated Contaminant Monitoring Rule it was tested for 29 PFAS and lithium 8 times across 2 sampling points between Feb 2024 and Sep 2025.
| PFAS | Detected | Highest | Worst point avg | EPA limit |
|---|---|---|---|---|
| 6:2 FTS 6:2 fluorotelomer sulfonic acid |
1 of 8 | 8.2 ppt | 2.1 ppt | none |
Not detected: PFOA, 4:2 FTS, PFBA, HFPO-DA, ADONA, 9Cl-PF3ONS, 11Cl-PF3OUdS, PFUnA, PFHxA, 8:2 FTS, PFDA, PFHpA, PFOS, PFNA, PFHxS, PFBS, PFTA, PFTrDA, NEtFOSAA, NMeFOSAA, PFDoA, PFHpS, PFPeA, PFMBA, PFEESA, NFDHA, PFMPA, PFPeS.
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.
Levels here are under EPA's limits, so no treatment is required. If you want them lower anyway, a certified reverse osmosis system under the sink handles drinking water, and a whole-house carbon filter also takes out the chlorine or chloramine your utility adds.
