The world’s largest sediment remediation project is currently taking place in northeastern Wisconsin at the Lower Fox River and Green Bay Superfund Site. The project began in 2008 and will ultimately result in the remediation of 7.5 million cubic yards of contaminated sediment.
Advanced Disposal has partnered with the project’s general contractor, Tetra Tech, to provide environmentally-sound waste disposal of approximately 3.4 million cubic yards of sediment contaminated by polychlorinated biphenyls (PCBs), a toxic substance and probable human carcinogen. From 1954 to 1971, several pulp and paper production facilities released PCBs into the Fox River directly or after passing through the region’s municipal wastewater treatment plants. PCBs have a tendency to sink and adhere to sediments along the river bottom, and the result was a contaminated area stretching for nearly 40 miles from the Lower Fox River through the bay of Green Bay to the point where it enters Lake Michigan. The waterways also contain other contaminants such as dioxins, arsenic, lead, mercury and the pesticide DDT, and the project’s remediation process will address these substances as well. … read more
