Well Drillers Near Lake Ann, Michigan

A geological estimate for the Lake Ann area.

Detailed Summary

Based on synthesis of sampled well logs from the Lake Ann region, the most representative subsurface section includes: a thin topsoil/sand layer, followed by a sand and gravel unit, then interbedded clay and sand/gravel sequences, often with repeated alternations. The primary aquifer is commonly a medium to coarse sand/gravel unit. Clay layers are prevalent between 30–120 ft, with sand or sand/gravel again prevalent below. Average residential static water level is about 35–55 ft; typical residential wells target the main sand/gravel aquifer at 80–110 ft, while higher capacity/irrigation wells extend to 200–270+ ft and target deeper sand/gravel. Most wells use rotary drilling with bentonite slurry grout and PVC casing.
