Well Drillers Near Greenleaf, Wisconsin

A geological estimate for the Greenleaf area.

Detailed Summary

Based on an aggregation of well logs sampled from the Greenleaf area and surrounding townships, the most representative geologic sequence begins with a widespread clay layer (sometimes interbedded with sand or gravel), usually between 15 and 165 ft thick (average ~80-90 ft). This is commonly underlain by a thin hardpan/compact till layer (~2–8 ft), which transitions to a persistent bedrock aquifer comprised chiefly of limestone or dolomite. The bedrock aquifer typically begins between 40 and 170 ft below ground surface and continues with high consistency to drilled depths of 120–330 ft in most wells. Sandstone is observed in some deeper locations starting around 400–500 ft and extending much deeper, but is not present in all logs. Typical residential wells achieving 5–15 GPM or more are drilled 120–180 ft deep, with high capacity wells or those seeking deeper sandstone aquifers extending to 300–500+ ft.
