Well Drillers Near Trego, Wisconsin

A geological estimate for the Trego area.

Detailed Summary

Based on synthesis of sampled logs, the dominant stratigraphy in the Trego region consists of upper fine to coarse sand (sometimes with silt or clay), underlain by sandy clay or hardpan in some locations, transitioning to thick, water-bearing sand and gravel layers that provide the main aquifer zones. Occasional hardpan, silt, or sandrock is present, but not widespread. The typical residential well targets the sand/gravel aquifer at 65–100 ft. High-capacity wells for agricultural/municipal use are usually not much deeper, as bedrock is rarely encountered before ~120–130 ft. Most wells use rotary mud drilling with PVC or steel casing and a cement or bentonite grout seal. Static water levels generally range from 10–60 ft below surface depending on local elevation and recharge.
