Madison's drinking water meets all federal and state standards for health and safety

Postcards have arrived in mailboxes across Madison letting people know their drinking water meets or exceeds all federal and state standards for health and safety. The cards announce the release of the Annual Drinking Water Quality Report, which provides an overview of the tens of thousands of drinking water quality tests Madison Water Utility conducted in 2021.

Every home in Madison should have received a postcard, directing people to the following link so they can review the report in detail:

Madison Water Utility takes the quality of the city’s water very seriously, routinely collecting more samples and running far more tests than are required by the Environmental Protection Agency (EPA) and Wisconsin Department of Natural Resources (DNR).

Madison’s drinking water system is made up of over 900 miles of water main, 32 reservoirs and 21 active wells that draw water from a plentiful sandstone aquifer below the city. All Madison Water Utility facilities are monitored 24 hours-a-day, and drinking water safety tests are conducted daily at every operating well and reservoir in Madison.

To request a paper copy of the report, please call (608) 261-9299 (voicemail only)
