Well Drillers Near Onekama, Michigan

A typical residential well in the Onekama area is drilled to approximately 85 feet to ensure a reliable water supply of 5-15+ gallons per minute.

The static water level, or water table, is typically found around 12 feet below the surface in this region.

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.
