    conclusion that the St. Lawrence River sediment plume follows the southern shore of the estuary. The more sparsely distributed modern sediment deposits along the north shore tend to be derived from local sources. Introduction The upper estuary of the St. Lawrence receives sediment from a variety of sources, the major one. In highly urbanized areas, wastewater treatment plant (WWTP) effluent can represent a significant component of freshwater ecosystems. As it is impossible for the composition of WWTP effluent to match the composition of the receiving system, the potential exists for effluent to significantly impact the chemical and biological characteristics of the receiving ecosystem.

    We evaluated the potential of vegetation and sediment habitats in wetlands of the St. Lawrence River for developing a macroinvertebrate bioassessment program with reference conditions. During September , we collected macroinvertebrates in emergent vegetation and sediment in both fluvial sites (reference) and tributary-plume sites (impacted) in waters of the north and south shores of Lake. “Despite extensive dredging of the St. Lawrence River, the cleanup goals of 1 mg/kg PCBs, 10 mg/kg PAHs, and 1 μg/kg TDBFs were not achievable in all areas. As a result, a acre, 15 cell area, containing a range of PCB concentrations from mg/kg PCBs to mg/kg, was capped with the first layer of a three-layer cap to achieve.

    Metals sites as well as with the contaminated river sediment removal in the St. Lawrence River at General Motors. Further dredging is planned in the St. Lawrence River at Reynolds Metals during the summer construction season of Before, during and post-remediation monitoring is needed.
