Detailed Summary

Based on multiple well constructions in and around Reedsburg, a representative geological profile consists of an uppermost clay or sand and gravel layer, commonly 5-20 feet thick but locally extending to 40-60 feet as sandy and silty materials. This is typically underlain by a sequence of sandstone units (often medium hard, brown or red), occasionally with thin interbeds of clay/silt or minor limestone and shale. The main aquifer for residential supply is the sandstone, which is generally encountered between 40 and 120 feet and may extend deeper. Casing is typically set through unconsolidated material and into the top of bedrock (40-65 feet). Water is usually obtained from sandstone at depths of 60 to 120+ feet, with static water levels commonly 5 to 70 feet below ground surface. Rotary mud drilling with cement or bentonite grout is standard. High-capacity wells may be constructed deeper into the sandstone sequence.
