Well Drillers Near Harrison, Michigan

A geological estimate for the Harrison area.

Detailed Summary

Based on a synthesis of multiple wells across Harrison, MI, the most representative geological sequence begins with a surficial sand, sand & clay, or thin topsoil layer (often 1-5 ft), underlain by extensive zones of brown/red/yellow/gray clay or sand & clay mixtures (15–60 ft thick globally), sometimes with thin lenses of gravel or sand. The persistent, most productive water-bearing aquifer occurs as a coarse sand or sand and gravel unit found between 40 and 100 ft bgs, thickness typically 10–30+ ft, often preceded and followed by clay layers. Static water levels cluster between 12 and 25 ft, and the best producing wells use rotary or hollow rod methods and PVC or steel casing, typically 4–5 inches in diameter, set nearly the entire depth. Grouting is generally bentonite slurry or dry granular bentonite, and most wells use a screened interval positioned through the basal sand/gravel. A typical residential well needs to reach the bottommost sand/gravel, which is where reliable 10+ GPM supply is consistently found.
