Detailed Summary

A representative geological sequence for Frederic, Wisconsin, based on well logs, consists of an upper sand or sand/gravel layer, underlain by alternating clay and coarser granular units (sand, gravel, silt). In a few deeper wells, a hardpan, silt, or occasionally a weathered bedrock is hit at greater depths. Most productive residential wells are completed in the main sand/gravel aquifers above any hardpan or silt encountered, with static water levels commonly between 6 and 59 feet and estimated well yields exceeding 5-15 GPM. Wells are mostly rotary-drilled, cased through the unconsolidated zone, and grouted from surface to casing tip.
