7.02 Water Quality

This page includes data that provide two perspectives on water quality. The first data set, from the University of Wisconsin Population Health Institute, is based on data from the U.S. Environmental Protection Agency (EPA) on drinking water safety. The EPA measures drinking water safety in terms of the percentage of the population served by a community water system with reported violations of health-based EPA regulations. The second data set, from the Wisconsin Department of Natural Resources (DNR), includes the number of miles of rivers and streams and square miles of lakes and ponds impaired by water pollution, and the priority level of water pollution in these impaired waterways. Water pollutants include polychlorinated biphenyls (PCBs), phosphorus, sediment, mercury, ammonia, and polycyclic aromatic hydrocarbons (PAHs).

Notes

Waterways may have multiple pollutants. Priorities are based on Total Maximum Daily Loads (TMDLs) established by the Wisconsin Department of Natural Resources to measure the maximum amount of a pollutant that a body of water can receive while still meeting water quality standards. For the Surface Water: Impaired Lakes & Ponds (2014) chart, there were no data available for Outagamie.
