Wisconsin’s drinking water is facing a growing crisis of nitrate contamination. That’s according to a new report by the Alliance for the Great Lakes. Nitrates are commonly caused by fertilizers, manure, and agricultural runoff. They can be harmful to people at high levels. In Wisconsin, agriculture accounts for 90% of nitrate contamination - but communities are often left footing the bill for cleanup.  

Angela Blatt is the senior agriculture policy manager at the Alliance for the Great Lakes, and she joins me now to talk about the report.
