Water Quality Standards

The Water Quality Control Commission is responsible for adopting water quality standards for surface water and ground water in Colorado. These standards (including use classifications, narrative and numerical standards, and antidegradation provisions) are set forth in specific Commission regulations (see "Current Water Quality Standards" link below). Standards are used for assessing the quality of Colorado waters and for establishing regulatory requirements for activities that may impact water quality.
