Lower Fox River PCB Clean-Up

Northeast, WI

In 2004, The Boldt Company was chosen by the Wisconsin Department of Natural Resources (WDNR) to oversee a 15-year dredging and capping effort, aimed at significantly reducing the hazards of polychlorinated biphenyls -- commonly known as PCBs -- from the lower Fox River.

Between 1954 and 1971, nearly 690,000 pounds of now-banned PCBs were released into the 39 miles of the Fox River that runs between Little Lake Butte des Mortes near Neenah, north to Green Bay, of which approximately 60,000 pounds of PCBs remained in the river's sediments. These hazardous PCBs were a by-product of carbonless paper manufacturing, which bound to the river sediment particles and eventually sank to the riverbed, where they were eaten by tiny organisms and passed on to fish, wildlife and eventually; humans.

As Technical Oversight Manager, the goal for The Boldt Company is to successfully help the WDNR achieve the remediation objectives, listed in the Record of Decision, providing input, assisting in the monitoring of project activities, and facilitating collaboration between key players. These include the firms deemed responsible for the contamination, their consultants and contractors, and governmental agencies.

Leveraging experience gained from large project collaborations with a knowledgeable and experienced team of consultants, as well as Boldt's project management expertise, Boldt's role is to:

  • Review input on all topics concerning cleanup activities, as well as samples taken from yet-to-be remediated river sections
  • Offer technical input and support for the evaluation of proposed remedies and offers alternatives
  • Confirm cost estimates and proposed schedules for all aspects of the remedial action
  • Participate in sessions designed to develop new remediation techniques
  • Provide status reports to multiple government officials, as high-level as the Governor

By the end of 2010, more than 2,200,000 cubic yards of sediment had been remediated (dredged, capped, covered) resulting in the remediation of approximately 16,000 pounds of PCBs. In addition, the project has surpassed a million work hours without a single lost-time incident
