Salt and storm water

Wisconsin winters cause us to rely heavily on salting our roads, parking lots and sidewalks. But high salt use causes Wisconsin’s lakes, streams and drinking water to suffer. The growing salt problem threatens our fish and other aquatic life, and our groundwater that supplies our drinking water. We can continue to keep our roads, parking lots and sidewalks safe by using the right amount of salt. Take action by participating in one of the winter salt certification trainings held throughout the state.
