Well Drillers Near Richland Center, Wisconsin

A geological estimate for the Richland Center area.

Detailed Summary

Based on well records from across Richland County in the vicinity of Richland Center, the most representative geological profile starts with a surface layer of clay, sandy silt, or sandy dirt (with or without gravel), becoming interbedded with silty or organic clay. This is typically followed by a thick sequence of shaley materials (often tan/brown, soft or hard), sometimes with thin limestone layers in the upper part of the sequence. Progressing deeper, alternating but dominated by hard shale and medium to hard brown or white sandstone units are observed. Sandstone becomes especially significant below 90–100 ft in most wells, comprising the principal drinking water aquifer. Shallower, high-yield unconsolidated sand/gravel aquifers occur in some areas but are not regionally extensive. Typical residential wells (5–15+ GPM) are completed in the upper to middle portions of the main sandstone unit, generally between 100 and 250 ft. High-capacity wells or deeper residential wells may extend 250 to 400 ft, accessing thicker, regional sandstones below more extensive shale units.
