Each year, Tucson Water conducts thousands of tests on the drinking water it delivers to make sure it is safe. The results are published in the Annual Water Quality Report (also known as the Consumer Confidence Report or CCR).
Above is the 2013 Annual Water Quality Report for the Main System and the reports for our 10 isolated systems. A Spanish-language version of the Main System report is also available. If you would like a paper copy of any of the 2013 reports, call 520-791-2544 or e-mail WQinfo@tucsonaz.gov.

Annual reports for previous years are available on the Annual Water Quality Reports Archive page.
The format for Tucson Water's Annual Water Quality Reports follows guidelines set by the United States Environmental Protection Agency (EPA) as part of the Safe Drinking Water Act. The EPA requires all public water providers to deliver this information to all customers on an annual basis in a single report that provides water quality data to the public in an understandable manner.
