The Dubuque Water Department provides high-quality water that is in compliance with all standards set forth by the Environmental Protection Agency. Over two hundred tests a day are performed by water treatment plant operators.

In addition to these tests, the Dubuque Water & Resource Recovery Laboratory performs over 120 bacteriological analyses of our drinking water on a monthly basis. Other compliance-related testing is performed by the University of Iowa Hygienic Laboratory and Keystone Laboratories. All of these analytical measures ensure that the water reaching your home is safe to drink.
