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.

The Great Lakes-St. Lawrence River system (Laurentian Great Lakes) extends more than km inland from the Atlantic Ocean to almost the midpoint of the North American continent.
The basic character of the Great Lakes was established during the last glacial retreat in North America, some 10–12 thousand years ago (Hough ).
Relating macroinvertebrate community structure to environmental characteristics and sediment contamination at the scale of the St. Lawrence River Article (PDF Available) in Hydrobiologia (1) Parasites were examined in yellow perch, Perca flavescens (Mitchill, ), from four localities ranging in degree of pollution in the St.
Lawrence River, Quebec, Canada, to examine the effects of the most prevalent parasite species on expression of biomarkers of oxidative stress. Various biomarkers appeared to be affected by the infection levels of Apophallus brevis Ransom, and genus.
There is still no assessment of the impact of sediment chemicals and environmental conditions on macroinvertebrates at the scale of the St. Lawrence River. In order to assess these impacts in the fluvial section of the St. Lawrence River including the Montreal harbour, the community structure of macroinvertebrates using different taxonomic aggregations (genus and family) and taxa.
