Well Drillers Near Brooklyn, Wisconsin

A geological estimate for the Brooklyn area.

Detailed Summary

Based on surveyed well logs, the generalized subsurface profile for the Brooklyn region (Dane/Rock counties, WI) consists of a surficial clay or fill layer (often 4-12 ft thick), underlain by sand and gravel (variable thickness commonly 10-60+ ft), sometimes interbedded with clay lenses. Below these unconsolidated sediments, wells typically encounter limestone/dolomite between ~40-130 ft (often with a shaly or sandy component), frequently grading into sandstone bedrock (sometimes alternating with dolomite/limestone) to final well depths of 125-258 ft. Static water levels are most often between 15-60 ft below surface, with residential wells to 120-150 ft and high-capacity/hicap wells ranging deeper but generally under 250 ft. Rotary mud circulation is the standard drilling method, with casing/grouting extending at least to bedrock or 110-180 ft.
