Wisconsin Drinking Water Systems Have Sterling Pass Rate

Wisconsin has the most public drinking water systems in the entire country, and almost all passed the standards in the state’s latest water report. The Department of Natural Resources this week released their Annual Drinking Water Report for 2023. The state has 11,206 systems statewide. The report said in part, “During 2023, more than 99% of Wisconsin’s public water systems provided water that met all the health-based Maximum Contaminant Level standards for regulated contaminants. Only 70 systems experienced MCL exceedances. Exceeding a maximum contaminant level does not necessarily mean that consumers experienced adverse health effects from drinking the water, but it does require a water system to notify consumers and take action to correct the problem.”
