Detailed Summary

Analysis of representative well construction logs from Bruce, WI indicates a typical stratigraphy consisting of an upper zone of clay or hardpan, with intermixed sand and gravel layers. Below these unconsolidated materials, wells commonly penetrate into harder formations, either granite or sandstone, which serve as the main aquifers for residential supply. Clay and clay-gravel mixtures predominate the uppermost 30-70 feet, followed by clean or dirty sand/gravel zones of varying thickness. Where present, bedrock (granite or sandstone) is typically encountered from 70 to 160 ft. The most common drilling method is rotary with mud circulation, with steel or plastic casing set across unconsolidated zones. Most residential wells suitable for 5-15+ GPM can be constructed to depths between 60 and 120 ft, though some require greater depths (up to 160+ ft) to reach sustained yields or stable formations.
