Geology & Depth
Wisconsin's glacially-shaped landscape has thick drift deposits in the north and east, with sand and gravel providing productive shallow aquifers. The Driftless Area in the southwest was never glaciated and has Cambrian-Ordovician sandstone and Silurian dolomite bedrock with fracture-dependent yields.
Most residential wells in Wisconsin are drilled to 145 feet, with a typical range of 30–400 feet. Water table depth: 20-80 feet in glacial deposits; 50-300 feet in bedrock formations; the Cambrian-Ordovician can be tapped at 100-1,000 feet.
Permits & Licensing
Wisconsin requires all water well drillers and pump installers to be licensed by the Wisconsin DNR. The program includes rigorous examinations. No homeowner exemption — all wells must be drilled by licensed contractors.
Permit authority: Wisconsin Department of Natural Resources (DNR); all wells must be constructed by licensed well drillers and pump installers. Expect $25-$100 in permit fees.
Primary Aquifer
Sand and Gravel Aquifers / Cambrian-Ordovician Sandstone Aquifer / Silurian Dolomite Aquifer. About 27% of Wisconsin households use private wells, with the highest rates in the rural northern and western counties.
Best drilling months: April through November; northern Wisconsin frost depths of 5+ feet limit winter access severely.
Common Water Quality Concerns
Wisconsin well water commonly contains: nitrate, arsenic in northeastern counties, radium in deep sandstone, iron, manganese, hardness. A comprehensive water test after drilling (typically $150–$500) will identify which treatments, if any, your well needs.
