How many labs test for PFAS in Pennsylvania

25 labs on Pennsylvania's official drinking-water lab list are certified to test for PFAS. All 25 are named for PFAS on the list. The Pennsylvania list does not say which labs take samples from homeowners, so call a lab before you send one. 19 are located outside Pennsylvania.

The list is published by the Pennsylvania DEP - Laboratory Accreditation Program. List version on file: STALE - report dated 6/11/2024. Fetched 2026-10-29 (UTC).

Old list. This list is from PA DEP's bulk drinking-water reports printed June 11, 2024 (chemistry and microbiology; the microbiology file is named 06-13-2024). PA DEP's own private-well water-testing page still links these two June 2024 reports (checked Nov 14, 2026); its live lab search did not respond to us on Oct 29 or Nov 14, 2026. Labs may have been added, dropped or changed since then.

Before you send a sample, call the lab to confirm it is currently certified for the exact test and method, that it accepts samples from homeowners, and how to collect and ship them. Status can change between list updates.

Why test for PFAS in Pennsylvania

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 3,470,761 people in Pennsylvania 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: Pennsylvania.
