Well Drillers Near Calumet, Michigan

A geological estimate for the Calumet area.

Detailed Summary

Across Calumet and surrounding areas, well logs typically show an upper unconsolidated sequence largely consisting of alternating sand, gravel, and clay layers, between 30 and 60 ft thick, sometimes with boulders or cobbles. Below this, wells commonly encounter a consolidated bedrock zone, most often described as sandstone (occasionally listed as 'Freda Ss', red/soft) or basalt ('broken' or hard). The transition to bedrock usually occurs near 40–60 ft, with some variation depending on local glacial deposits or proximity to Lake Superior. Drilling is often by cable tool or rotary methods, with typical casing set into bedrock. Most residential wells reach total depths of 90–130 ft for reliable supplies of 5–15+ GPM. Deeper bedrock wells (especially in basalt) may extend to 150–200+ ft, though not all high-capacity yields are assured at these depths. Static water level is usually between 8 and 25 ft below grade, occasionally artesian.
