Well Drillers Near Grant, Michigan

A geological estimate for the Grant area.

Detailed Summary

Based on the synthesis of several well logs from the Grant, MI region, the representative geologic profile consists of an initial surficial sand layer (10–20 ft thick), an intermediate blue or gray clay unit (10–20 ft thick), and a main lower sand or sand and gravel aquifer, which is generally the primary water-bearing zone. This main sand aquifer frequently extends from roughly 30–35 ft below grade to the bottom of most residential wells in the 75–100 ft depth range. Thinner or additional clay lenses may also be present locally, but as a rule, this three-layered sequence dominates. Residential wells yielding 10–25 GPM are most often completed between 75–90 ft, with static water levels averaging near 30 ft below grade. High capacity wells (Type II public or irrigation) can be completed to similar or slightly deeper depths depending on demand, but rarely exceed 110 ft in this setting.
