Over 95 percent of Wisconsin’s municipal water utilities are meeting safe drinking water standards.
According to a report from the state Department of Natural Resources, there were 449 violations of safe water standards at just over 100 of the state’s eleven-thousand-500 systems in 2018.
The report says more than half the systems were among the over 95-hundred licensed campgrounds, parks, motels, restaurants, churches, and other public service businesses that aren’t considered a primary source of public drinking water. Some of the contaminants included bacteria, nitrate, arsenic, and radionuclides.
