About 6,442 households in Ashtabula County, 16% of the county, rely on a private well. Nobody tests that water unless the owner does.
About one in 6 households in Ashtabula County relies on a private well, around 6,442 homes. Outside the towns with public water, wells are the norm here.
The rules that apply in Ashtabula County are set at the state level in Ohio. New wells must be tested before use, and nothing is required at sale. Some counties and townships add permits or setbacks of their own, so check locally before drilling. The state's own recommendations are below.
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).
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.
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.
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.
The nearest certified lab is Geauga County Department of Water Resources in Chardon, about 27 miles from the county center, and it accepts samples from homeowners. There are 3 more within 40 miles, listed below with what each tests for.
