Water Quality

The District regularly checks its water for contaminants and is required by federal and state regulations to test for 166 constituents. Trained staff collects samples from wells, storage facilities, points in the distribution system, and residents’ homes. The samples are analyzed by State licensed laboratories. The test results are reported to the District and the State of Arizona. The District works closely with the Arizona Department of Environmental Quality (ADEQ) to ensure all water quality standards are met.
