Well Drillers Near Escanaba, Michigan

A geological estimate for the Escanaba area.

Detailed Summary

Unconsolidated surficial layers in Escanaba generally begin with a thin topsoil (1-2 ft), underlain by sequences of medium to fine sands (10-30 ft) and interbedded/clayey layers (40-60 ft total thickness). These are usually followed by compact 'hardpan', gravelly clay, or sand-gravel mixes. Groundwater is commonly encountered above 20-90 ft depth. The uppermost bedrock is dominantly limestone (often with interbeds of shale or sandstone deeper), beginning at 50-150 ft depending on location. Deeper wells may encounter further sequences of blue shale or consolidated limestones down to at least 225 ft, sometimes 400 ft where deeper drilling was reported. Most wells use rotary or cable-tool drilling and are cased (commonly steel or PVC) to around 50-144 ft, and are pressure-grouted with neat cement to ~100-140 ft. Static water levels average 12-55 ft below ground. Residential wells with 5-15+ GPM yields are most often ~105 ft, up to 150 ft; higher-capacity or bedrock wells may be 225-400+ ft.
