Well Drillers Near Nekoosa, Wisconsin

A geological estimate for the Nekoosa area.

Detailed Summary

Based on synthesis of the well logs, the predominant geology in the greater Nekoosa region is a thick, predominantly sandy surficial sequence (20–40+ ft), occasionally underlain by a clay or silty layer (about 5–15 ft thick), and then returning to sand/gravel below. Some higher capacity wells in regional logs extend deeper (to ~80 ft) and may terminate in or on weathered sandstone. Most domestic (residential) wells are completed between 30–45 ft with screens set in clean sand or sand/gravel. Static water levels range from 13 to 32 ft but average about 17–20 ft. Construction is almost universally by rotary-mud with 6 in. steel or poly casing, and a bentonite or cement grout is typical. Sufficient yields for residential purposes (5–15+ GPM) are consistently achieved in the screened sand/gravel interval. High-capacity irrigation wells are typically set to 75–81 ft and may involve sandstone.
