About Your Water Quality

WATER QUALITY UPDATE (August 30th, 2023): On Saturday, August 19th, 2023, customers were notified about a groundwater well that had tested positive for E. coli. The untreated water was not in service to customers. We are pleased to report that the problem has been corrected. We appreciate your patience.

Tucson Water's Water Quality and Operations Division environmental scientists, chemists, analysts, disinfection personnel, system and water treatment operators, and inspectors work together to monitor the quality of our drinking water at more than 200 wells, 61 reservoirs, 266 sampling stations, and 125 selected homes throughout the Tucson Water service area.
