Well Drillers Near Randolph, Wisconsin

A geological estimate for the Randolph area.

Detailed Summary

Based on reviewed well logs in the Randolph area and nearby communities, the typical subsurface profile starts with thin clay (often with gravel/silty materials), followed by a significant massive limestone/dolomite layer, and then a thick, water-bearing sandstone formation that serves as the main aquifer. Occasional shale interbeds may be noted in the transition from limestone to sandstone. The most common drill method is rotary with mud circulation. Residential wells typically reach depths of 120–140 feet to access sufficient, reliable yields. High-capacity wells often extend deeper to optimize yields from the sandstone aquifer.
