Detailed Summary

Across representative well construction logs in the Whitelaw and broader Manitowoc region, the prevailing geological profile from ground surface to typical well depth is: a thin surficial layer (topsoil, hardpan, or gravelly sand); a substantial sand layer (sometimes gravelly); a thick clay (often red, blue, or sandy); and then a transition to limestone bedrock, which forms the main water-producing zone. Some variability in clay color/composition and presence of gravel/sand is present, but the most persistent sequence is sand over clay over limestone. Residential wells commonly terminate in or just below the limestone, with high yield (5–15+ GPM) at depths between 100–150 feet. High capacity wells may extend deeper depending on bedrock characteristics.
