Yes, at low levels. 1 PFAS was detected, all below EPA's 2024 limits.
Also detected, no federal limit: PFBS.
Woodmoor WSD is a public water system drawing on surface water, based in Monument, Colorado, serving about 18,031 people. Under EPA's Fifth Unregulated Contaminant Monitoring Rule it was tested for 29 PFAS and lithium 14 times across 5 sampling points between Feb 2024 and May 2025.
| PFAS | Detected | Highest | Worst point avg | EPA limit |
|---|---|---|---|---|
| PFBS Perfluorobutanesulfonic acid |
1 of 14 | 3.3 ppt | 0.8 ppt | none |
Not detected: ADONA, NMeFOSAA, NEtFOSAA, PFTrDA, PFTA, PFHpA, PFHxS, PFNA, 9Cl-PF3ONS, HFPO-DA, PFBA, 6:2 FTS, 4:2 FTS, PFHpS, PFUnA, PFHxA, PFDoA, 11Cl-PF3OUdS, 8:2 FTS, PFOS, PFDA, PFPeS, NFDHA, PFEESA, PFMBA, PFPeA, PFMPA, PFOA.
Lithium, tested in the same program: highest 31.8 ppb, detected in 14 of 14 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.
