Well Drillers Near Wausau, Wisconsin

A geological estimate for the Wausau area.

Detailed Summary

Analysis of a cross section of well logs throughout the greater Wausau region reveals a highly consistent geology. Most residential wells begin with a surface clay layer, ranging from 3 to 20 feet, sometimes mixing with sand or gravel and occasionally underlain by a thin decomposed or weathered rock interval. Below this, virtually all wells encounter fractured Precambrian granite to the full depth drilled (typically ~180–300+ feet, depending on yield and location, but sometimes deeper for high-capacity or low-yield sites). The static water level is usually 10–40 ft below ground, and productive residential wells commonly end in the granite at 180–260 ft, though site-specific yields can require deeper drilling.
