Detailed Summary

Representative residential and municipal wells in the Onekama region most frequently encounter a surface layer of fine to medium sand with local gravel, followed by alternating sequences of sand, sand with clay, and layers of silty or gray/brown clay. Deeper stratigraphy generally transitions into thick, contiguous clay, capped by water-bearing sands or sand-gravel units at greater depths (>80 ft). Very deep wells (>250 ft) may encounter massive sand aquifers below thick clay. Static water levels are typically shallow (10-20 ft below grade) in most household wells, though can be significantly deeper in select locations (e.g., >100 ft). Wells achieving 5–15+ GPM are commonly completed at 50–110 ft, screened in the basal sand/gravel aquifers encountered below the principal clay sequence. High capacity municipal wells may require drilling 200–500+ ft, depending on local variations and increased clay thickness.
