Digitized edition from print [produced by Environment and Climate Change Canada]. Includes bibliographic references. "In 2009 to 2010, 22 stations were sampled in the St. Mary's River focusing on East Bellevue Marine Park (EBMP) and Lake George Channel (LGC), two potentially problematic areas identified in previous studies. Increasing sampling stations coverage in both EBMP and LGC provided assistance in developing a sediment management strategy for the St. Mary's River. Data were collected on the benthic invertebrate community structure, functional responses of benthic invertebrates using laboratory toxicity tests, and the physical and chemical attributes of the sediment and overlying water. Conditions at test sites were compared with those at Great Lakes reference sites using multivariate techniques. Data were applied to the Canada-Ontario decision-making framework for contaminated sediment to determine environmental risk. This report also includes an overview of previous studies conducted in the river from 2002 to 2010, including Bellevue Marine Park, providind a comprehensive picture of conditions in the depostitional areas of the river"--Exec. summary, p. i.
