Well Drillers Near Strum, Wisconsin

A geological estimate for the Strum area.

Detailed Summary

Based on the synthesis of several well logs in the Strum region (western Wisconsin, Trempealeau/Eau Claire counties), the typical well encounters a very thin topsoil or clay layer (<1–12 ft), followed by sequences of brown sand, fine/medium sand, and sometimes gravel to about 40–80 ft deep. Most commonly, this transitions to brown/gray/green sandstone, ranging from 40 to over 200 ft. In certain locations, an intermediate shale or claystone zone is present. Deeper wells (>100 ft) commonly penetrate firm to hard sandstone of varying color (brown, green, gray) with occasional shale. Static water levels and common yield (5–15+ gpm) indicate that residential wells can typically be completed in the upper to middle sandstone units. High-capacity wells often extend deeper within these consolidated sandstones.
