Well Drillers Near Kalkaska, Michigan

A geological estimate for the Kalkaska area.

Detailed Summary

A representative Kalkaska County well profile displays an upper section of brown/yellow sand, often with inclusions of gravel or some loam, extending commonly down to 40–50 ft. Underlying this, many wells exhibit one or more clay layers (yellow, tan, gray) between 3–40 ft thick, separating distinct aquifer sands. Coarse, water-bearing sands or sand/gravel units are the main aquifers, encountered both above and below the intervening clay. In deeper areas, brown or gray clay and gravel appears at 120–245 ft depth, with a final coarse sand/gravel aquifer present to total depths of up to 260 ft. Most residential wells are completed at 40–90 ft, while some are drilled deeper for greater yield (up to 260 ft).
