Well Drillers Near Windsor, Wisconsin

Windsor and neighboring regions typically have overburden of clay, sand, and gravel (often in multiple thin layers), underlain by a major sandstone aquifer. Limestone/dolomite is found either above or as interbeds within the sandstone in some wells, with occasional shale streaks. Residential wells most commonly terminate in sandstone at 125–180 ft depth, with static water levels reported between 21–75 ft below ground and typical yields above 10 GPM.

Detailed Summary

A generalized geological profile for the Windsor, WI region (based on synthesis of recent well logs) is as follows: The uppermost material consists of a variable thickness (8–20 ft) of clay, often sandy or mixed with gravel, sometimes including surface fill. This is frequently underlain by lenses of sand, sandy gravel, or silty sand to depths of 30–50 ft, occasionally interbedded with peat or soft clay layers, especially in lower/valley areas. Beneath the overburden, a prominent sequence of sandstone begins, usually extending from about 40–65 ft to 125–180 ft, sometimes containing thin beds of shale or shaley sandstone (notably 60–130 ft). In several wells, limestone or dolomite beds are observed either immediately above or within the upper sandstone (commonly around 10–60 ft and/or 110–170 ft). While some locations report hard limestone/dolomite at depth, the regionally persistent and productive groundwater aquifer is the sandstone. Typical residential wells (supplying 10–20+ GPM) are completed into sandstone around 140–180 ft total depth, with static water levels most commonly observed between 40–75 ft below grade. Deeper high-capacity wells (irrigation/municipal) may extend to 200–300+ ft but have similar geologic layering. All sampled wells were constructed by rotary drilling with mud circulation and grouted with neat cement or mud.
