Why test for PFAS in Maine
EPA's 4.0 ng/L limits for PFOA and PFOS cover public water, not private wells, and its May 2026 proposals to roll back four other PFAS limits are not final. Read our PFAS explainer.
About 660,497 people in Maine used private wells in 2015, by the USGS estimate of people on domestic self-supplied water. [1] Federal limits are written for public water systems, not private wells, so testing is up to the owner.
For tests that depend on your home (farms nearby, old plumbing, a new baby), use the which-tests checklist. When results arrive, check your numbers against EPA's limits. State guidance, county data and every lab: Maine.
