Well Drillers Near Grand Rapids, Michigan

A geological estimate for the Grand Rapids area.

Detailed Summary

Synthesis of representative well logs indicates the prevalent Grand Rapids region sequence is 15–25 ft of clay at the surface, followed by alternating sand/gravel (often 20–50 ft thick) and additional clay or sandy clay. Below 40–60 ft, wells often encounter coarser sand and gravel layers, typically used for water supply. In the deepest (100–150+ ft) wells, a few logs encounter limestone or sandstone bedrock. The most common water-bearing zones are major sand or sand/gravel strata between 25 and 90 ft. Static water levels are typically found at 15–50 ft below grade. A standard residential well for 5–15+ GPM is usually completed between 60–100 ft, with high-capacity wells extending to deeper sand/gravel or into the top of bedrock, around 120–160 ft total depth. Thin gravels or varying silt are noted but are less consistent and omitted in this generalization.
