The aquifers of the Missouri and Vermillion Rivers in Clay County, South Dakota are important sources of water for municipal and agriculture use. Nonincorporated residential developments in rural areas in southeastern South Dakota have greatly increased over the last fifteen years. With this growth the chance for septic system contamination of underlying shallow aquifers has greatly increased. The proper use of soils overlying and draining into the aquifers is critical in maintaining water quality. As a result of this concern for potential pollution hazards and septic system failures, a study was initiated to identify soil limitations for septic tank absorption fields. The bulletin and its maps are meant to point out potential problem areas and not provide very detailed site information. It is designed to serve as a guide for county and state officials as they plan the development of the county.
