Detailed Summary

Synthesis of well logs in the Decatur, MI region shows a consistent stratigraphy of surficial clay (often intermixed with sand), transitioning to significant sand and/or gravel aquifers which are the main target for residential and high-capacity wells. Typical wells encounter alternating clay and sand/gravel beds, with coarsest and most productive layers at depths of 80-130 ft. Residential wells for household use are usually screened between 90-110 ft, yielding 10-15+ GPM. Static water levels are typically 30-80 ft below grade. Rotary mud drilling is the standard method, with PVC casing and bentonite slurry grouting predominating.
