Well Drillers Near East Jordan, Michigan

A geological estimate for the East Jordan area.

Detailed Summary

Analysis of well logs from the East Jordan area indicates a most common sequence of: (1) a thin surface sand or gravelly sand layer; (2) thick deposits of clay, sandy clay, or clay with gravel/sand lenses; (3) an underlying coarse sand/gravel or, in western/central sections, limestone bedrock at greater depths. Domestic wells commonly tap the coarse sand/gravel aquifer or bedrock at depths between 40 and 80 ft for sufficient yield (5–15+ GPM), but some wells penetrate over 100 ft where more clay is present. Static water levels generally range from 10 to 60 ft below grade, with artesian conditions occasional near major surface waters. Rotary mud circulation is the standard drilling method, and bentonite slurry is the prevailing grout material.
