How many labs test for VOCs in Pennsylvania
38 labs on Pennsylvania's official drinking-water lab list are certified to test for VOCs. All 38 are named for VOCs on the list. The Pennsylvania list does not say which labs take samples from homeowners, so call a lab before you send one. 23 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.

Why test for VOCs in Pennsylvania
Volatile organic compounds come from fuel, solvents and their breakdown products, and because they evaporate they reach you through the shower as well as the tap. Read our VOCs 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.
