Beach closures, fish kills, green lakes. They are unfortunate signs of summer in Wisconsin. A big reason: untreated animal waste. Large dairies can produce as much waste as a small city. It's not only hard to deal with, it's dangerous if it gets into our water. Animal manure is one of the biggest sources of water pollution in Wisconsin. Now, some of Wisconsin's largest dairies are suing the state, trying to limit oversight of the way they handle animal waste. Wisconsin Manufacturers and Commerce quietly filed the lawsuit just before Memorial Day weekend on behalf of the Wisconsin Dairy Alliance, a lobbying group representing a number of large concentrated animal feeding operations (CAFOs). In this episode, Amy talks with Clean Wisconsin water and agriculture program director Sara Walling and attorney Evan Feinauer to find out what the lawsuit means for Wisconsin's water resources and public health.
