Ohio has about 1 million homes using private wells. Since property owners are responsible for the well water quality, annual water testing for homes with private water supplies is recommended. Many private laboratories in Ohio will analyze water from public and private water supplies. This publication lists laboratories willing to accept water samples from the public for testing. These water testing laboratories are approved by the Ohio Environmental Protection Agency and Ohio Department of Health (as of 2021 at epa.ohio.gov/Portals/28/documents/labcert/Combined-Lab-List.pdf). The list includes the names of laboratories in various counties of Ohio, addresses, phone numbers and websites. The Laboratories are certified to conduct certain types of chemical analysis and are labeled accordingly.

Check the fact sheet Household Well Water Testing AEX 314 (ohioline.osu.edu/factsheet/aex-314) on what to test for and how to collect a water sample. Other publications on water testing and water treatment can be found online at setll.osu.edu.
