Well Drillers Near Croswell, Michigan

A typical residential well in the Croswell area is drilled to approximately 80 feet to ensure a reliable water supply of 5-15+ gallons per minute.

The static water level, or water table, is typically found around 40 feet below the surface in this region.

Synthesizing the available well log records for the Croswell, MI area, the local geology is best described as a multi-layered glacial sequence. The near-surface is often a thin topsoil over brown or yellow sandy clay, followed by a thick interval of massive or stony gray clay, occasionally interbedded with silt or isolated sand lenses. In many cross-sections, thin to moderate beds of clean sand and/or gravel (sometimes water-bearing) appear at shallow to moderate depths (20-40 ft), but the main aquifer is a thicker, water-productive sand, sand/gravel, or fine sand unit at approximately 60-120 feet below grade. This basal unit typically supplies the best yields (5-20+ GPM for residential use) and is the most commonly targeted interval for screened well completions. Deeper massive clays may continue below, based on deeper wells south and west; however, the greatest reliance is on this intermediate sand/sand-gravel horizon. Grouting (typically with bentonite slurry) is often used to at least 40-100 ft, with PVC or steel casing set nearly to screen depth.
