Protecting water quality and balancing the competing demands on this limited resource for current and future generations is important for the health of the environment, welfare of our citizens and the economic well-being of our state. Water quality standards are established to protect the five use classifications: drinking water supply, recreation, aquatic life, agriculture and wetlands.

Here you can view data on:
  • Percent of rivers, streams, lakes and reservoirs that meet Clean Water Act standards
  • Amount of contaminated water from hazardous waste sites and mining sites treated per year
  • Number of Colorado residents served by public drinking water systems that are not in compliance with uranium and radium standards
