Description:
Pilot biomonitoring and monitoring studies were conducted at the Saginaw Confined Disposal Facility (CDF), Saginaw Bay, Lake Huron, during 1987 to develop methods to assess the potential for magnitude of 1) contaminant transport from the dike interior to the outside environment, 2) impacts of CDF disposal on the water column and sediments, and 3) impacts of CDF disposal on aquatic biota living in the outdike zone. olychlorinated biphenyls (PCBs) were selected for study due to their presence in the sediments of the Saginaw River/Bay ecosystem. athematical model of near-field contaminant transport through the dike is expected to be small, amounting to less than 0.25 kg of PCBs after 5,000 days of simulation. athematical model of the far-field impacts of CDF transport was also constructed. odel predictions indicate that the incremental increase in steady-state, water column PCB concentrations in Saginaw Bay is expected to be approximately 0.05 mg/L per kg of PCB transported from the CDF. iomonitoring program was developed to assess contaminant transport through dike walls and its impact on contaminant concentrations in biological tissues. istinct transport of contaminants through the dike walls was not demonstrated using the biomonitoring approach.
