Detailed Summary

Based on the reviewed well logs for the Amherst region and adjacent townships, the general stratigraphy consists of a thin layer of topsoil or clay at the surface, followed by a thick, largely unconsolidated sand or sand & gravel sequence. Occasional lenses of fine sand, silt, or clay may be present, especially below 40–60 feet. The main aquifer for domestic and irrigation use is a medium-coarse sand or sand & gravel layer, typically found from 30–100 feet. Residential wells supplying ~10–25 GPM generally complete in this zone at 80–105 feet. Casing is typically set to about 60–100 feet, terminating above or within the primary aquifer, with screen material across the coarser zone. High-capacity irrigation wells are set deeper but access the same dominant aquifer system.
