Meeting Water Quality Standards
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
. All of these analytical measures ensure that the water reaching your home is safe to drink.
