Well Drillers Near Maple, Wisconsin

A geological estimate for the Maple area.

Detailed Summary

Wells in the Maple region typically encounter an initial layer of sand or dirty sand from surface to about 10–20 ft, followed by a substantial zone of clay, hardpan, or silty material extending to approximately 70–100 ft. Below this, bedrock is most commonly encountered, with either basalt/trap rock or sandstone being observed stretching down to reported depths of 180–300 ft. The first significant water-bearing unit is usually the sand/hardpan-capped upper bedrock, often basalt. Static water levels are shallow to moderate (15–50 ft), but deeper bedrock wells frequently report water tables below 70–100 ft. A typical residential well supplying 5–15+ GPM is completed at around 80–140 ft, sometimes deeper for basalt wells. High-capacity or slow-yield (≤1 GPM) wells may reach 200–300+ ft, reflecting persistent, thick, low-porosity basalt. Casing typically extends through unconsolidated units, ending just at the bedrock interface.
