Well Drillers Near Kewaskum, Wisconsin

Typical Kewaskum area wells encounter 2 to 4 unconsolidated layers dominated by sand, gravel, clay, and silt, occasionally underlain by limestone or dolomite bedrock. Residential wells commonly tap sand and gravel aquifers within the first 80–130 ft; high-capacity/municipal wells may encounter deeper or more extensive clay and bedrock layers.

Detailed Summary

Based on synthesis of sampled well logs from Kewaskum and vicinity, the most representative geological profile begins with a surficial sequence of interbedded sand, gravel, clay, and silt, typically extending to about 85–135 ft. In some locations, clay zones can be significantly thicker (up to nearly 300 ft in deep wells), but most domestic wells access water from the coarse sand and gravel units above or just below the thickest clay. A hard limestone/dolomite bedrock is occasionally reached below unconsolidated materials at depths >80–250+ ft, with some deep wells penetrating hundreds of feet of clay before meeting fractured limestone. A typical residential well producing 5–20 GPM is usually completed in the sand and gravel aquifer at 70–130 ft. Static water levels generally range from 5–55 ft below ground surface.
