Detailed Summary

The representative geological profile for Williamston and adjacent areas begins with an upper layer of sand, clay, and gravel, ranging to about 50-70 feet. This is followed by alternating layers of gravel, sand, and dense clay, giving way to thick sequences of shale (often gray, black, or white), commonly interbedded with sandstone and occasionally limestone in the deepest sections. This profile generally supports productive residential wells at 120-180 feet for yields of 10+ GPM, with higher capacity wells completed deeper into the bedrock, down to 220-420 feet where sandstones and some limestones increase yields.
