Detailed Summary

Based on synthesis of the provided well logs from the Hartford, Richfield, and adjacent Washington County region, the typical geological profile consists of surficial sandy and/or clayey layers, followed by repeated, thick, coarse sand and gravel intervals occasionally separated by hardpan or clay seams. Most residential wells are completed within these unconsolidated deposits, which frequently extend from the surface down to depths ranging from around 60 feet to over 325 feet. The most common sequence starts with a mixed sand and clay or clayey gravel near the surface, transitions to alternating bands of sand/gravel and clay/hardpan several times with increasing depth, and generally terminates at or just above 300–325 feet with coarse gravel or sand. Static water levels typically range from 10 to 150 feet, depending on topography and location, and 5–15+ gpm is commonly achieved at depths of 60–200 feet, while high-capacity wells are finished deeper within continuous sand/gravel aquifers.
