PFAS above EPA’s limits in West Virginia.
The short answer
10 utilities serving 99,088 people, as they report it, had a location averaging above a limit, most often PFOA (8) and PFOS (2). The largest is Parkersburg Utility Board, whose highest PFOA average was 29 ppt, 7.3 times the limit. The furthest above is Lubeck PSD, at 22 times the PFOA limit.
These are EPA’s survey results, not violations: the limits take effect April 26, 2029, and compliance will rest on each utility’s own monitoring. EPA has proposed changes to the rule; as of Oct. 13, 2026, none is final.
