How the Ohio list marks public samples (whole list). Not stated. The list covers public drinking-water certification.
Before you send a sample, call the lab to confirm it is currently certified for the exact test and method, that it accepts samples from homeowners, and how to collect and ship them. Status can change between list updates.
Why test for lead in Ohio
On a private well, lead almost always comes from the metal the water touches on its way to your glass, and corrosive water decides how much. Read our lead explainer.
About 1,861,023 people in Ohio 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: Ohio.
