Water Well Drilling Contractors in Ohio

Geology & Depth

Ohio's glaciated western two-thirds has thick drift deposits with productive sand and gravel buried valley aquifers — remnant channels of ancient rivers. The unglaciated southeastern quarter has Pennsylvanian-age sandstone, shale, and coal-bearing bedrock with lower yields and more variable water quality.

Most residential wells in Ohio are drilled to 140 feet, with a typical range of 30–400 feet. Water table depth: 20-80 feet in glacial buried valleys; 50-300 feet in southeastern bedrock.

Permits & Licensing

Ohio requires water well drillers to be registered with ODNR. Drillers must pass an examination covering well construction standards. Homeowners may install their own wells but must follow all construction standards and file completion reports.

Permit authority: Ohio Department of Natural Resources (ODNR), Division of Soil and Water; county health departments issue construction permits in some areas. Expect $25-$150 in permit fees.

Primary Aquifer

Glacial Buried Valley Aquifers (Great Miami, Scioto, Miami Buried Valleys) / Pennsylvanian Sandstone Aquifers. About 18% of Ohio households use private wells, concentrated in Appalachian southeastern Ohio and rural western Ohio.

Best drilling months: March through November; mild winters in the southern counties allow some year-round work.

Common Water Quality Concerns

Ohio well water commonly contains: iron, hardness, hydrogen sulfide, manganese, brine contamination near old oil and gas wells, bacteria. A comprehensive water test after drilling (typically $150–$500) will identify which treatments, if any, your well needs.
