Detailed Summary

The majority of water well logs from Sioux Falls show a consistent near-surface layer of fill (often silty sand or clay, sometimes with minor gravel), followed by a zone of interbedded silty sand and clay or glacial outwash (SM/CL), typically grading into a thicker, coarser, well-sorted sand or sand/gravel layer below about 9-13 ft. This basal aquifer (coarse sand or sand/gravel) is unconfined, water-bearing, and most residential or monitoring wells are set at 15 to 22 ft. Static water levels typically range from 6 to 15 ft below surface. One-off occurrences of bedrock or deeper gravels are rare within the urban area and not considered representative. Residential wells seeking 5-15+ GPM typically target the coarse sand/gravel aquifer at 18-22 ft.
