Well Drillers Near De Pere, Wisconsin

A geological estimate for the De Pere area.

Detailed Summary

Based on synthesis of well construction reports for De Pere and adjacent areas, the most representative profile begins with a surface interval of clay or sandy clay (~20-50 ft thick), often with underlying sandy gravel (to 60-110 ft), transitioning into limestone/dolomite which can extend for several hundred feet. A substantial shale layer is commonly present, frequently below 50–70 ft and continuing for several hundred feet (when deep drilling occurs), occasionally separated into upper and lower limestone units. At greater depths (commonly ~300–650 ft, where deeper drilling is performed), sandstone is encountered. Shale is more variable but generally appears as a major confining layer within the limestone sequence. Water yields are variable but strong, with static levels from 10 to 420 ft and typical residential wells completed between ~60 and 220 ft depending on yield needs.
