Synthesizing well logs across Kewaunee County, the most representative geologic profile begins with a substantial interval of clay (sometimes with stones or gravel), extending from the surface to approximately 30-140 feet, depending on local conditions. This is frequently underlain by a discontinuous sand and/or gravel or stony interval of moderate thickness (ranging from 10 to 40 feet), acting as a transition to the underlying limestone/dolomite bedrock aquifer. The bedrock limestone is universally encountered and constitutes the primary water-bearing formation. Casing generally anchors into the top of bedrock, with wells completed open-hole in limestone. Static water levels are highly variable but most commonly range from 15 to 100 feet below ground surface. Wells producing 5–40+ GPM for a residential setting typically reach 100–165 feet, with high-capacity systems extending to 200+ feet as needed. All wells are constructed by rotary mud circulation with a cement or clay slurry grout seal.
