Where this list comes from
Read on 2026-09-20 from 1 document published by Ohio Environmental Protection Agency. This page lists what those documents list — not necessarily every laboratory Ohio certifies — so check the official directory below before you rely on it.

Ohio EPA Laboratory provides some direct testing; many county health departments offer subsidized bacteria testing
How to choose one of these labs
- 1.Shortlist two or three: start with the labs in your own city above, because most drinking-water samples must reach the lab within 24-30 hours of collection
- 2.Verify certifications: confirm the lab holds current state certification for the specific contaminants you want to test (bacteria, nitrate, metals, VOCs, PFAS). Certification is per-analyte, and a certificate number on this page is a starting point, not a guarantee it is still current
- 3.Request pricing: call multiple labs to compare prices and turnaround times—costs vary significantly even within the same state
- 4.Schedule testing: follow lab instructions for sample collection, storage, and delivery
- 5.Review results: compare detected concentrations against EPA standards and take appropriate action
