GRAND CANYON, AZ — During the early morning on Thursday November 9, 2023, our water system did not provide adequate levels of chlorine in the water being used from Roaring Springs.
As a result, our water was not disinfected as the Arizona Department of Environmental Quality (ADEQ) requires. Therefore, our water system violated a treatment technique standard for maintaining adequate disinfection for water delivered to customers from Roaring Springs. As our customers, you have a right to know what happened and what we did to correct this situation. After this problem was identified, Operators immediately notified the State Drinking Water division and Grand Canyon started the process to identify the source of the failure. The source was identified, and adequate chlorination was restored on Friday morning, November 10, 2023.
