Detailed Summary

Based on averaging lithological descriptions and depths from multiple wells, the representative stratigraphy includes: (1) a surface layer of sand or sandy clay (sometimes with gravel), (2) zones of clay or silt interbedded with sand and/or gravel, and (3) a thick, regionally extensive sequence of sandstone, often light brown or gray and hard, starting typically between 60-100 feet and extending to well bottoms between 114-160 feet. Static water levels typically range from 28-90 feet below surface, and most area wells encounter sufficient water yield at depths of approximately 90-135 feet. The sandstone aquifer is the primary water-producing zone.
