Well Drillers Near Holmen, Wisconsin

A geological estimate for the Holmen area.

Detailed Summary

Holmen and greater La Crosse County wells predominantly encounter a thick brown sand or sand-and-gravel unit from land surface to between 60 and 130 feet. A minority of wells (especially to the south/east) may encounter sandstone or shaley sandstone beneath the unconsolidated aquifer, but most household supply wells are completed within the sand/gravel. Static water levels are variable, most commonly ranging from 10-90 feet below ground surface, with pumping levels for 10+ GPM commonly 20-110 feet. Casing typically extends to near the bottom of the sand/gravel, with screen or open intake at the base. Rotary mud circulation is the most common drilling method. The most reliable geology is: thick unconsolidated brown sand/sand-gravel, locally with clay-rich cap, over possible sandstone/shale at greater depths.
