Well Drillers Near Shawano, Wisconsin

The typical Shawano area well profile consists of a surficial sand/sandy clay unit, locally developed clay or clay/gravel, and a deeper sequence of glacial material or shallow consolidated limestone and sandstone, with most productive residential wells finished in sand or shallow sandstone/limestone at about 40-130 feet.

Detailed Summary

Based on synthesis of multiple well logs, Shawano's typical geological profile is a sequence beginning with a sand or sandy/silty clay unit at the surface, often followed by layers of clay, gravel or silty sand. In the east and center, limestone or dolomite bedrock is commonly encountered at approximately 70-125 ft, while in other areas unconsolidated sands dominate to total well depths around 50-130 ft. Sand and sandy aquifers are the principal residential sources. Water levels are generally 15-80 ft below grade. For higher capacity/municipal wells, holes may be drilled to 140-305 ft, sometimes into bedrock, but most residential wells meet yield requirements at 50–130 ft.
