Traver Well Drilling
Vassar, MI48768
Vassar region household wells typically penetrate thick glacial clay and gravel overburden, followed by shale, sandstone, and minor limestone layers, with residential wells generally completed within sandstone or sandstone/limestone units between 140–170 ft. Water is usually encountered at 12–35 ft below grade.

Recommended Method
Analysis of representative well logs around Vassar shows a consistent sequence of glacial sediments (sand, gravel, clay, and stones) to around 90–110 ft depth, followed by alternating shale and sandstone bedrock units, sometimes with thin limestone interbeds. The most common sequence is a clayey or clay-gravel overburden, then shale, and the main aquifers used in household wells are commonly in sandstone or combined sandstone/limestone intervals between 120–170 ft. Static water levels are typically 12–35 ft below ground surface. Yields for residential use (5–15+ GPM) are reliable in this range.
