Detailed Summary

The representative geological profile for Muskego consists of a surficial brown/tan clay or sandy clay unit extending to approximately 15–25 ft, underlain by blue or stony clay to ~140 ft. Thin gravel, sand, or sandy clay lenses are sometimes encountered within the glacial sequence, generally between 110–146 ft. The glacial deposits usually overly competent limestone bedrock, which commonly appears between 140–190 ft. Most residential wells terminate in the limestone interval, with casing to or just into the rock. Static water levels vary (22–52 ft bgs), commonly around 30 ft. The typical depth for residential wells capable of 5–15+ GPM is 140–180 ft; high-capacity wells (municipal) must be over 1500 ft to reach the deep Cambrian-Ordovician sandstones. Outliers and deeper municipal stratigraphy are omitted to create a 'typical' Muskego residential profile.
