Detailed Summary

Wells in the Hortonville region characteristically pass through a thin surficial clay (or clay with gravel or sand admixture), grading into limestone/dolomite and prominent sandstone aquifers. These carbonate and sandstone bedrock units alternate with typical first significant limestone/dolomite bedrock appearing between 10 to 45 ft, underlain by alternating sequences that may transition more than once with depths. Overall, groundwater is typically sourced from limestone/dolomite or sandstone at depths between 90 and over 200 ft for high capacity. Wells consistently use rotary-mud circulation, with surface casing extending to the base of unconsolidated material (~40–100 ft), and are sealed with neat cement or mud grout. Static water levels mostly fall in the 35–90 ft range. Given pump test yields, a reliable residential well (5–15+ GPM) is generally achieved by 130 ft, while high-capacity installations target depths of 180–230+ ft.
