Water Quality and 401 Certification
Water Quality Standards for Wetlands
Water quality standards are an effective tool available to States to protect the overall health of their wetlands resources and the valuable functions they provide, including shoreline stabilization, nonpoint source runoff filtration, wildlife habitat, and erosion control, which directly benefit adjacent and downstream waters. Water quality standards, including designated uses, criteria, and an antidegradation policy can provide a sound legal basis for protecting wetland resources through State water quality management programs.
Water Quality Criteria and Standards Program Information related to water quality, biological, aquatic, and wildlife criteria and state water quality standards. Includes three Watershed Ecological Risk Assessment case studies.
