Yes, at low levels. 1 PFAS was detected, all below EPA's 2024 limits.
Also detected, no federal limit: PFBA.
Bethesda WSC is a public water system drawing on surface water, based in Burleson, Texas, serving about 33,441 people, including Burleson, Cleburne, Mansfield, Fort Worth. Under EPA's Fifth Unregulated Contaminant Monitoring Rule it was tested for 29 PFAS and lithium 24 times across 10 sampling points between Feb 2025 and Nov 2025.
| PFAS | Detected | Highest | Worst point avg | EPA limit |
|---|---|---|---|---|
| PFBA Perfluorobutanoic acid |
4 of 24 | 5.9 ppt | 2.9 ppt | none |
Not detected: PFHxA, PFUnA, 11Cl-PF3OUdS, 9Cl-PF3ONS, ADONA, HFPO-DA, 6:2 FTS, 4:2 FTS, 8:2 FTS, NEtFOSAA, PFHpA, PFTrDA, PFTA, NMeFOSAA, PFDoA, PFDA, PFOA, PFOS, PFHxS, PFBS, PFPeS, NFDHA, PFEESA, PFPeA, PFHpS, PFMPA, PFMBA, PFNA.
Lithium, tested in the same program: highest 68.6 ppb, detected in 15 of 24 samples. EPA's health-based screening level is 10 ppb.
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.
