Tucson Water is committed to producing and delivering drinking water that is clear, clean and secure for our customers and the community. Our drinking water meets all federal National Primary Drinking Water standards.
Water Quality and Operations Division chemists, planners, analysts, disinfection personnel, system and water treatment operators, environmental scientists, and inspectors work together to monitor the quality of our drinking water at more than 400 wells, reservoirs, sampling stations and homes throughout the Tucson metro area and surrounding communities. We test for 150 different chemicals and microbes and report the information to the Arizona Department of Environmental Quality, the U.S. Environmental Protection Agency, and to our customers.
