At a glance

Water test for a new wellRequired

Under OAC 3701-28 a permit from the local health district is required before a well is drilled or altered. When the work is done, the owner asks the health district for the final inspection, and a sanitarian collects the water sample: total coliform, E. coli and nitrate. The system is approved only when the sample passes (4 or fewer total coliform per 100 mL and no E. coli for a well without continuous disinfection).

Water test when a home is soldNot required statewide

No statewide requirement. Most local health districts offer a real-estate evaluation of the well on request (a visual inspection plus a bacteria and nitrate sample), and some lenders ask for one. Ask the county health district for its fee and turnaround.

What the state recommends

ODH recommends a total coliform and nitrate test every year, and every time the water changes in taste, color or smell, after flooding, or after any work on the well or pump. Add arsenic, iron and manganese, hardness and sulfate at least once, and PFAS or methane where local conditions call for it.

Free or low-cost testingAvailable

No statewide free program. Several county health districts run their own labs (Erie, Logan, Mahoning, Canton City among them) and sell bacteria and nitrate tests at cost; others sell bottles from a certified lab. OSU Extension fact sheet AEX-315 lists labs that accept samples from homeowners.
