"Between 1975 and 1982, Water Quality Branch, Ontario Region, collected water quality samples in the Niagara River system. This report summarizes the results obtained for toxic contaminants and trace metals from these monitoring activities. Various types of samples, including unfiltered water samples, suspended and bottom sediments and spottail shiners (Notropis hudsonius), have been analyzed for these constituents. In addition, large volume (200 L) aqueous phase water samples were extracted for toxic organic contaminants. Data have been subdivided into two major categories: (1) data collected at a single fixed station at Niagara-on-the-Lake and (2) data collected at various survey stations throughout the Niagara River system. Violations to the 1978 Great Lakes Water Quality Agreement specific objectives or Ontario Ministry of the Environment guidelines are indicated, and loadings to Lake Ontario have been calculated and presented"--Abstract, p. vii.
