Well Drillers Near North Prairie, Wisconsin

A geological estimate for the North Prairie area.

Detailed Summary

In the North Prairie region, the predominant geological profile consists of a surface layer of sand and gravel, typically extending 30–60 feet deep, underlain by alternating clay (including hardpan) and sand/gravel layers to approximately 100–130 feet. Shallow bedrock is commonly limestone or dolomite, beginning between 90–130 feet, with major shale (especially blue and gray, often described as hard) present from 80–280 feet in deeper wells. Deeper limestone/dolomite layers can extend from 150 to over 400 feet in high capacity wells. Residential wells yielding 5–20+ GPM are generally completed between 100 and 200 feet; deeper completions (to >400 ft) are rare but occur for higher capacity or dual aquifer settings.
