PFAS in New Mexico drinking water: EPA’s final survey results
EPA’s national PFAS survey (UCMR 5) tested 81 of the community water systems that serve homes in New Mexico. 11 found at least one of 29 PFAS above the laboratory reporting level, and 1 had a PFOA or PFOS sampling-location yearly average at or above EPA’s 4.0 ppt limit. Samples were collected from January 2023 to March 2026.
Data as of EPA UCMR 5 final release, August 2026 (file dated Aug 28, 2026) · EPA SDWIS 2026Q2 (file dated Jul 9, 2026). How we build these pages
PFBS was the compound New Mexico community systems found most often: 4 of 81 tested systems measured it above the reporting level.

The largest New Mexico system with a detection, Epcor Water New Mexico INC Clovis, serves 41,066 people and found 1 of the 29 compounds.
Which PFAS were found most often in New Mexico
Each row counts the New Mexico community water systems where that compound was measured above the reporting level at least once. A detection is a measurement, not a violation: most of these compounds have no federal limit.
