A generalized geologic profile for Glenwood City, based on multiple well logs, indicates the uppermost 40–60 feet is dominated by brown/tan clay, sometimes with thin organic soil or sand/gravel atop. Below the clay, a gray clay or mixed clay/limestone layer is often present, continuing to around 100–160 feet. From 100–180 feet, limestone or dolomite predominates and serves as the principal water-bearing formation for most wells. Where deeper drilling occurs (beyond 180 feet), sandstone or shaly units are occasionally encountered. Most residential wells providing 5–15+ GPM are completed in limestone/dolomite between 120–180 feet depth, with typical static water levels of 70–100 ft, though deeper levels exist in some areas.
