Well Drillers Near Yale, Michigan

A geological estimate for the Yale area.

Detailed Summary

Based on synthesis of regional well logs, the representative geological column for Yale is: (1) a thin layer of topsoil/clay (1-10 ft); (2) a thick sequence of dense clays and/or clay mixed with sand or gravel extending through at least 30-45 ft; (3) interbedded, water-bearing sand and sand/gravel units typically found from 45-105 ft; (4) in some wells, further sequences of clay, silt, and gravel may extend to ~175 ft; (5) at greater depths (100-200+ ft), some wells encounter shale or sandstone. Water supply for most residential applications comes from sand and sand/gravel layers between 60-105 ft. Static water levels generally range from 5 to 55 ft below ground. Drilling methods are predominantly rotary (mud/cable tool), wells are grouted with bentonite/cement to between 75-160 ft, and typical casing is steel or PVC to just below the major aquifer.
