Well Drillers Near Ashippun, Wisconsin

A geological estimate for the Ashippun area.

Detailed Summary

Based on regional well logs, the typical Ashippun-area geological profile begins with a surficial clay (with cobbles and gravel) unit, typically 5-10 feet thick, followed by a sand and gravel aquifer extending to depths of about 40-60 feet. Some wells encounter secondary clay/gravel or clayey sand layers below, and in deeper locations, a transition to limestone/dolomite bedrock occurs, commonly starting between about 120-130 ft depth but occasionally documented deeper. Residential well screens are most often set in the sand and gravel aquifer above any bedrock, which provides sufficient yield for typical household demands. The static water table generally sits between 18 and 64 feet below grade, with drawdown typically moderate. The most common drilling method is rotary with mud circulation, and casings are set just above or into bedrock, grouted with cement or granular bentonite.
