Well Drillers Near Dexter, Michigan

A geological estimate for the Dexter area.

Detailed Summary

In the Dexter region, most wells encounter a sequence beginning with a surficial sand, loam, or clay layer (typically yellow/brown, ~5-25 ft thick) followed by interbedded layers of sand/gravel aquifer material and clay (both soft and hard) down to 60–80 ft. From 60–90 ft, cemented sand/gravel, sandstone, or compacted clay may appear, especially in deeper wells. Bedrock, generally as sandstone or limestone, is reported at ~85–136 ft. Most residential wells (5–15+ GPM) are screened in the major sand/gravel aquifer lying between 40 and 90 ft. Static water levels range from 15 to 35 ft below grade. Modern construction prefers rotary drilling, with 4–5 inch PVC or steel casing, and bentonite slurry grout to the top of screen or bedrock.
