SCOPE Surface water has a direct impact on environmental health, the ecosystem, recreational uses, and is a source for water consumption. Protecting surface water quality ensures availability of safe, clean water for all South Dakota citizens. Protecting water quality while allowing economic growth. Each water body in South Dakota is designated for beneficial use. The designated beneficial use(s) of the stream or water body water establishes the minimum quality standards. If a water body cannot meet those water quality standards it is designated as impaired.
Impacts to Water Quality Water quality is impacted by two primary methods: non-point and point source pollution. Non-Point Source
Non-point source discharges, such as stormwater, are the runoff from agriculture or urban environments that can also impact environmental health, ecosystems, and recreational uses, and is essential to protecting drinking water. Stormwater flood control is regulated through federal programs such as the National Flood Insurance Rate program (NFIP) through FEMA, and the NPDES program through the EPA. The NPDES is managed by the SD DANR, and NFIP is managed by participating communities. The management of drainage and stormwater runoff is a critical component in the recharge of an aquifer, which impacts receiving water bodies. Stormwater quality management occurs at the local level, within each community.
