Melville, NY · Public samples: ask the lab
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.
