Detailed Summary

Synthesizing well logs from the Allenton region, the most representative geological profile begins with surficial sand, clay, and gravel deposits extending from the surface to roughly 70-90 feet, followed by alternating sand/gravel and clay-silt lenses. The uppermost consolidated bedrock is typically limestone or dolomite starting near 70-90 feet. Some deeper wells reach dolomite/shale and, rarely, deep sandstone. Most residential wells are completed at depths of 120-200 feet targeting the limestone/dolomite aquifers, providing sufficient yield for domestic supply. High-capacity wells may be completed at greater depths, sometimes over 350 feet if targeting deeper sandstone or fractured dolomite.
