Well Drillers Near Gladwin, Michigan

A geological estimate for the Gladwin area.

Detailed Summary

Based on a representative sample of Gladwin County well logs, a typical geological cross-section begins at the surface with a thin sand, topsoil, or sand/clay/gravel mix, immediately underlain by several thick clay units occasionally interbedded with sand or sand/gravel. Coarse sand, sand & gravel, or sandy clay units commonly provide water-bearing aquifers, typically between 60–150 ft, used for residential supply. In deeper wells (>150–200 ft), thick clay, shale, and sandstone formations are observed, forming the base of the glacial drift and defining deeper aquifer zones. Static water levels typically range between 10–26 ft below grade for most residential wells. The rotary drilling method with PVC casing and bentonite slurry grout is standard. The most probable yield-producing aquifers for residential supply are the coarse sand or sand/gravel units (generally 70–150 ft deep). High-capacity or bedrock wells may target sandstone or sand/gravel zones at greater depths (down to 280–400 ft).
