Episode 16

The cold winters in Wisconsin always bring with them temperatures in the single digits, snowfall, and icy roads. Wisconsinites respond by applying a liberal amount of salt to roads and sidewalks to prevent people and vehicles from slipping. But once the ice is melted, where does the salt go? Host Rose Daily and guest Allison Madison explore the negative impacts of salt on our built world, natural environment, and human health, as well as what we can do to fight salt pollution.
