Detailed Summary
Analysis of well logs for the Jefferson region reveals a common stratigraphic sequence: a thin layer of topsoil, underlain by thick glacial clay, followed by a significant sand and/or gravel aquifer beginning around 60–120 ft, and then sandstone or bedrock often reached between 280 and 350 ft. The most productive residential wells for reliable yields (5–15+ GPM) are generally completed in the sand/gravel or basal sandstone intervals at 130–300 ft, with static water levels typically 15–25 ft below ground.
