Recommended Method
Based on a synthesis of well logs from the sampled Wyoming, MI area, the most common stratigraphy consists of alternating clay (gray, sandy, or hard) and sand (fine to coarse, occasionally water bearing) intervals. The sequence usually begins with a surficial soil or clay, underlain by alternating layers, with productive sand and gravel aquifers typically encountered between 20–80 ft deep. Deeper wells (150–250 ft) encounter thicker sequences of clay and sand, sometimes with boulders at depth. Most residential wells are screened in sand/gravel layers between 30–80 ft, supporting domestic yields. Static water levels are commonly 20–25 ft below grade. Most wells are drilled with rotary or cable tool rigs, PVC or steel casing installed, and bentonite or cement grout applied.
