Well Drillers Near Gaylord, Michigan

A geological estimate for the Gaylord area.

Detailed Summary

Synthesizing the provided well log samples from the Gaylord, Michigan region, the representative subsurface geology consists of a shallow cover of topsoil (1 ft), underlain by unconsolidated sand (often 5–10 ft, variable in color), transitioning into mixed sand and gravel or sand and boulders layers (extending to approximately 40–45 ft). In some wells, interbedded clay or clayey sand occurs at intermediate depths (30–65 ft). The principal aquifer zone is a thick, coarse sand and gravel unit beginning around 40–50 ft and extending to typical well bottoms (90–110+ ft depths). Static water levels are usually observed between 8 and 80 ft below grade. Wells consistently use steel casing to roughly the base of the primary aquifer, with screens set in coarse sand/gravel. The majority of domestic wells tested yield 10–15 GPM at pumping depths between 60 and 100 ft, though higher yields (20–45 GPM) and deeper wells (up to 145 ft) are documented. Rotary drilling with mud circulation is standard; bentonite or cement grout to 25–75 ft is typical.
