Water Quality Standards

New Mexico’s Water Quality Standards, codified at 20.6.4 NMAC, define water quality goals by designating uses for rivers, streams, lakes and other surface waters, setting criteria to protect those uses, and establishing antidegradation provisions to preserve water quality. The Standards are adopted by the Water Quality Control Commission (WQCC), then approved by the United States Environmental Protection Agency (US EPA) under the federal Clean Water Act (CWA). 

Contact  Jennifer Fullam, Standards Coordinator, with any questions about WQS activities.
