Annual Drinking Water Quality Report

Madison Water Utility adheres to the highest state and federal drinking water standards. We routinely collect more samples and run more tests than are actually required by the EPA and DNR -- thousands of tests every year. Those test results are reflected in our Annual Drinking Water Quality Report, showing Madison's water once again meets or exceeds all federal and state standards for health and safety.
