Well Drillers Near New London, Wisconsin

A geological estimate for the New London area.

Detailed Summary

Based on the synthesis of typical well logs from New London, the prevalent stratigraphic sequence consists of: a thin organic-rich soil layer, underlain by clay (often with stones or gravel), transitioning to sand and gravel or more massive sand (sometimes interbedded with clay), then locally a thick clay interval or firm hardpan, followed by sandstone (soft-to-firm), and in some areas underlain by limestone or crystalline basement (granite) at greater depths. Casing commonly extends through unconsolidated material to just into the bedrock. Static water level is generally found between 20 and 92 feet below ground surface. A typical residential well for sustainable yields of 5-15+ GPM is completed at 100-150 feet, often targeting the sand or upper bedrock aquifers. Higher capacity wells (or those requiring more drought protection) may be drilled deeper, up to 200-275 ft or more, especially where deeper sandstone or bedrock units are present.
