Well Drillers Near Mt Calvary, Wisconsin

A geological estimate for the Mt Calvary area.

Detailed Summary

An analysis of representative well logs from Mt Calvary and surrounding areas in Fond du Lac County indicates a consistent subsurface profile. The shallowest layers are predominantly clay (often red or gray) with interbedded sand or gravel seams. This unconsolidated zone commonly extends to depths of 20-40 feet. Below, a thicker sequence (extending from roughly 30-120 feet) of mixed gravel, sand, and clay occurs, sometimes showing gradational contacts. At approximately 90-120 feet, all wells encounter competent limestone or dolomite bedrock which is the principal water-bearing unit in the region. In deeper wells (particularly east of Mt Calvary), additional units such as shale or, more rarely, sandstone, may occur beneath the limestone. The typical static water level is between 15 and 85 feet below ground surface, varying with local elevation and land use. Most successful residential wells (providing 5-15+ GPM) are completed at depths of 90-130 feet within the limestone aquifer, whereas higher capacity/community wells may be drilled deeper if thicker limestone or deeper aquifers are present.
