Detailed Summary

Based on synthesis of sampled well logs, the most representative geologic profile in the Genoa, WI region features: an initial 3-10 ft of topsoil/dirt/clay, followed by 10-100+ ft of soft to hard shale. In various logs, there may be intermittent limestone or limerock with crevices, and in some cases, a basal sandstone or sandrock. The typical residential well accessing 10+ GPM is cased to ~100-120 ft and completed in the upper shale or underlying limestone or sandstone where present. High-capacity wells may penetrate much deeper into shale or limestone layers. Static water levels range from 35-90 ft below surface. Most wells employ rotary mud drilling and are sealed with neat cement grout.
