Old list: check before you rely on it
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's currently certified for the exact test and method, that it accepts samples from homeowners, and how to collect and ship them. Bacteria samples have short holding times. Status can change between list updates. To check a status, contact the Pennsylvania certification program.
