Detailed Summary

Representative Platteville regional wells begin with a shallow clay layer, grading into Galena limestone, then Upper Platteville dolomite. This is followed by the Trenton (McGregor) limestone and a thick St. Peter sandstone aquifer. A minority of deeper wells encounter a basal shale (Readstown), and/or lower dolomite (Prairie du Chien) beneath the St. Peter. The majority of residential wells target the Trenton or the upper to mid St. Peter sandstone for reliable yields (5-30 GPM). Most bedrock wells are constructed to between 180 and 260 feet; high-capacity or deeper exploratory wells may extend to 330+ feet.
