Each year, Tucson Water conducts thousands of tests on the drinking water we deliver to make sure it is safe. We provide customers with test results in our Annual Water Quality Report (also known as the Consumer Confidence Report or CCR).
The format for this report 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.
Listed below is the 2012 Annual Water Quality Report for the Main System (in English and Spanish), as well as 2012 Reports for Isolated Systems. Reports for previous years are available on the Annual Water Quality Reports Archive page.
