Well Drillers Near Somerset, Wisconsin

Typical Somerset area wells encounter a surficial sand/gravel or clay unit, transitioning to clay with gravel/cobbles or hardpan, then lime/limestone or sandstone bedrock at depth. Most productive aquifers are found in these consolidated layers below roughly 90-150 feet.

Detailed Summary

The most common geologic profile for wells in the Somerset, WI region begins with a surface layer of clay, sand, or sand and gravel, typically extending 25-120 feet. Below, a transition to dense clay with cobbles/boulders or a hardpan layer is encountered, extending to approximately 140-200 feet. The primary aquifer zone is most often found in either hard limestone or sandstone ('sandrock'), generally from 140-220 feet. Some wells may encounter limerock yellow hard, limestone, or white/hard sandstone at these depths. Static water levels vary, but are typically between 60-145 feet below ground, with residential well yields (5-15+ GPM) usually achieved between 95-200 feet depth, and high capacity wells often completed near or just below the main bedrock aquifer. Casing is typically set to just above the consolidated aquifer layer, and bentonite or cement grout is installed to similar depth. Drilling is by rotary mud circulation or similar method.
