Well Drillers Near Mio, Michigan

A geological estimate for the Mio area.

Detailed Summary

Based on sampled well logs from Mio, Michigan and its vicinity, a representative geologic profile begins with surficial sands (often medium to fine) extending down to variable depths (usually 15–25 ft, but occasionally as deep as 40–50 ft). This is typically underlain by a thick clay or clay-rich sequence (60–250+ ft in deeper wells), sometimes with interbeds of gravel or sand. Coarser sand and gravel—a primary aquifer—occur either above and/or below the main clay. In most deep residential and high-capacity wells, the screened interval targets these lower sand and gravel horizons, starting at approximately 80 ft to over 270 ft below grade. Very shallow wells (under 40–50 ft) draw from the upper sand layer, but these are less typical for higher yields and are mostly jet or hand-driven types. Most drilled wells in the area utilize rotary drilling with mud or bentonite slurry grouting, and PVC or steel casing is common. The static water level can be quite variable, but 5–40 ft is typical in shallow settings, reaching >100 ft in deeper, confined/deep gravel aquifers.
