Series: CAFOs, Manure And Water
Wisconsin's wealth of freshwater is foundational to the state's agricultural economy. As livestock farms in the state grow ever larger in the 21st century, their impact on this resource is growing. The largest of these farms are termed concentrated animal feeding operations, often called CAFOs. These farms with hundreds or thousands of animals not only require more water, but they also produce colossal amounts of manure. Managing this livestock byproduct is a major undertaking. Manure can serve as a resource for fertilizing crops or for generating energy. At the same time, this waste regularly enters surface and groundwater, contaminating wells and wildlife habitat. How manure is handled is a focus of policymaking, and its increasing volumes can contribute to contentious relationships between CAFO operators and their neighbors.
