Well Drillers Near Ludington, Michigan

A geological estimate for the Ludington area.

Detailed Summary

Based on synthesis of representative well logs from Ludington and adjacent townships, the typical stratigraphy consists of an upper sand or sandy loam (including topsoil), underlain by sequences of clay (often red, sometimes with sand/gravel interbeds). The thickest and most consistent confining unit is clay, generally overlain or underlain by varying sand layers. The main aquifer tapped for residential supply is most commonly a medium to coarse sand or sand/gravel unit found below a persistent clay layer, typically at depths of 50-80 feet, but sometimes as deep as 110-125 feet. The static water table is generally between 13 and 41 feet below grade, with most residential wells yielding 12-20 GPM at total depths averaging 78 feet. High-capacity (public or flowing) wells are deeper (~103-125 feet) to maximize gravel/sand aquifer thickness. The region is developed almost exclusively with rotary (mud) drilling, with PVC or steel casing and bentonite slurry grout.
