Detailed Summary

Averaging data from multiple wells in the Two Rivers/Manitowoc region, the representative geological sequence consists of: 65-80 feet of clay (in some cases with zones of fill in the uppermost part), often subdivided with interbedded hardpan or sandy clay; a transition (10-55 ft thick) of sand & gravel/ sand & clay/gravelly clay lenses sometimes split by minor hardpan or more consolidated clay; and finally, limestone/dolomite bedrock from roughly 120–200+ ft. Most residential wells are completed around 130–165 ft to ensure reliable yield (generally ≥10 GPM), while higher capacity wells or those targeting deeper bedrock may extend to 200 ft or more.
