Well Drillers Near Jackson, Michigan

A geological estimate for the Jackson area.

Detailed Summary

A representative Jackson County geologic section begins with variable surface coarse gravel and sand (0–20 ft), progressing through additional sand and/or sand with gravel layers (to ~80 ft), and locally with lenses of gray clay or silt (rarely >15 ft thick). Most wells penetrate into a soft to hard sandstone unit beginning between 40 and 80 ft, commonly extending to total depths of 95–150 ft. Lithologic units below the primary sand/gravel aquifer may include gray shale or limestone, with water typically produced from the sandstone/bedrock zone. Most residential wells are completed at 100–135 ft with yields of 10–15+ GPM. High-capacity wells may extend deeper into bedrock. The dominant drilling method is rotary (mud circulation) with PVC casing grouted with bentonite (usually to casing depth, ~90–115 ft).
