Water Quality Standards
National Information
Regional Information
Water quality standards are the foundation of the water quality-based pollution control program mandated by the Clean Water Act. Water quality standards define the goals for a water body by designating its uses (recreation, aquatic life, drinking water, industrial, agriculture), setting criteria to protect those uses, and establishing provisions to protect waterbodies from pollutants.
The major responsibilities of the Region 8 Water Quality Team are to:
- Assist states/tribes with development of new/revised water quality standards and implementation procedures, including providing comment letters on proposed water quality standards.
- Review and take action on new or revised state/tribal water quality standards.
- Consult with U.S. Fish and Wildlife Service on water quality standards approvals subject to the Endangered Species Act.
- Participate in national policy formulation.
