Background

The Lower Fox River, located in northeastern Wisconsin, begins at the Menasha and Neenah channels leading from Lake Winnebago and flows northeast for 39 miles where it discharges into Green Bay and Lake Michigan. Approximately 270,000 people live in the communities along the river. The river has 12 dams and includes the highest concentration of pulp and paper mills in the world. During the 1950s and 1960s, these mills routinely used PCBs in their operations which ultimately contaminated the river.
