Well Drillers Near Lapeer, Michigan

A geological estimate for the Lapeer area.

Detailed Summary

Synthesizing the Lapeer well log sample, the most prevalent geological sequence is: (1) surficial clay layer (≈20–25 ft), (2) followed by thick intervals of gravel, sand, and/or stony gravel to ~40 ft, (3) alternating clay, sand, or sand/gravel to ~60–100 ft, (4) transition into shale and/or sandstone, sometimes layered with minor limestone, from ~70–100 ft downward—bedrock aquifers being the primary water source to full depths between 150–300 ft. The most reliable aquifers appear to be sandstone or mixed shale/sandstone, with static water levels consistently between 4–30 ft below grade and high pump test yields (12–60 GPM). Residential wells commonly achieve 5–15+ GPM at 125–170 ft. Rotary mud drilling predominates, with PVC casing set to near bedrock and bentonite slurry grouting standard. This composite ignores isolated thicker sand or limestone intervals less frequently documented.
