Well Drillers Near Grand Blanc, Michigan

A geological estimate for the Grand Blanc area.

Detailed Summary

Based on an aggregate of representative well logs, the common geologic sequence in Grand Blanc consists of an upper clay unit (sometimes with boulders, stones, and thin sand/sand & gravel layers) from surface to about 100-120 ft, underlain by sand or sand & gravel lenses (20-60 ft thick), with additional clay or mixed lenses. Bedrock (sandstone, sometimes with shale) is encountered at 120-190 ft, and most wells are completed in the sandstone to total depths of ~160-280 ft. The static water level typically ranges from 20-65 ft. Typical household wells targeting 10+ GPM are completed at depths of 160-200 ft, while higher capacity wells may range up to 280 ft or more.
