Well Drillers Near Cadillac, Michigan

A geological estimate for the Cadillac area.

Detailed Summary

Based on synthesis of multiple well logs from Cadillac and adjacent areas, the representative geological profile begins with a surface sequence of sand (often up to 40–50 ft), sometimes mixed with silt or clay. This is typically underlain by alternating lenses of clay (commonly gray or red, thickness 10–50 ft) and sand or gravel (thickness 10–60 ft), with the most productive and persistent water-bearing zones found in medium to coarse sand (sometimes labeled as sand & gravel) between approximately 65–150 ft. Some deeper wells encounter multiple sand and clay aquifers to depths exceeding 200 ft. The static water level is generally observed between 70–100 ft below grade for typical residential wells. The most common drilling methods are rotary mud or cable tool, with PVC or steel casing set through surficial unconsolidated units and terminating in water-bearing sand. Grouting is most commonly with bentonite slurry or cement. A typical residential well yielding 10–15+ GPM is completed at 100–160 ft, while high-capacity wells may extend to 180–220 ft or more.
