Well Drillers Near Sparta, Wisconsin

A geological estimate for the Sparta area.

Detailed Summary

The representative Sparta-area geological profile comprises an unconsolidated surficial layer (sand, sandy loam, or clay) usually 10–21 feet thick, underlain by a moderately thick to very thick interval of saturated sand (where deep alluvium/glacial fill is present) or direct transition into sandstone bedrock. Sandstone is the persistent and dominant water-bearing formation, usually encountered from 18–21 feet and extending to well depths beyond 90–115 feet. Minor, localized clay or clayey sand or occasional gravel may appear between the unconsolidated surface and the main sandstone aquifer. Groundwater is generally encountered within the sandstone at moderate static levels. The average casing depth is 55–60 feet, and residential wells are typically completed between 73–117 feet. Rotary - Mud Circulation is the prevalent construction method, with cement or neat cement grout use for sealing.
