Well Drillers Near Hammond, Wisconsin

A typical Hammond-area well penetrates layers of topsoil, clay (sometimes with sand or gravel), sand/gravel, and thick limestone/dolomite bedrock. Residential wells (5-15+ GPM) are usually 100-130 ft deep; high-capacity or deep wells may reach 150-180+ ft.

Detailed Summary

The most representative geological profile for Hammond and surrounding areas, based on a synthesis of local well logs, consists of an uppermost layer of topsoil and/or clay, occasionally interbedded with sand or gravel. This is followed by a zone of clean sand and gravel (or sand/gravel with clay), which transitions to a competent limestone/dolomite bedrock that typically serves as the primary aquifer. The clay/sand/gravel zone thickness varies but is frequently between 15-60 ft before entering the limestone/dolomite aquifer. The static water table is typically found between 30 and 100 ft below grade, with wells completed in limestone commonly yielding 10-15+ GPM. Standard residential wells are 100-130 ft; deeper or high-yield wells extend to 160-180 ft or more.
