Book Description
Presents results of contaminant analyses of bottom sediments collected from the Peace and Athabasca river basins 1988-90 and 1992. Contaminant groups represented are the polychlorinated dibenzo-p-dioxins and dibenzofurans, resin acids, chlorophenolic compounds, and polycyclic aromatic hydrocarbons. Contaminant concentrations were correlated with percent organic carbon of the fine fraction (the fraction on which analysis was performed. Correlations between concentrations of bleached kraft mill related contaminants were also investigated and results are presented.

Book Description
The Northern River Basins Study was established to examine the relationship between industrial, municipal, agricultural and other developments and the Peace, Athabasca and Slave River basins. Over 4 1/2 years about 150 projects or 'mini studies' were contracted by the Study under eight component categories including contaminats, drinking water, nutrients, traditional knowledge, hydrology / hydraulics, synthesis and modelling, food chain and other river uses.

Book Description
Summarizes the major modelling projects undertaken to model water quality in the Peace, Athabasca, and Slave river systems. The first section describes the scope of the problem of modelling water quality in large complex systems that are relatively oligotrophic, located at relatively high altitudes, and experience highly seasonal environmental fluctuations. It also provides a summary of the models used to predict key water quality variables. Section 2 gives a general overview of the utility and shortcomings of water quality models, with the goal of establishing key criteria for assessing the successes of models developed by the Northern River Basins Study (NRBS). Section 3 summarizes key findings of the NRBS models and evaluates the results against criteria outlined in section 2. Section 4 presents a series of recommendations for modelling dissolved oxygen, transport and fate of contaminants, and distribution of contaminants in the food chain, along with strategic suggestions for future work.

Book Description
Presents results of site visits to 38 water treatment facilities located in the Northern River Basins Study area along the Peace, Athabasca, and Slave rivers. The 38 sites selected for the visits (out of 180 treatment facilities in the area) represent an overall cross-section of the types of facilities found in the area, based on existing data regarding raw water source, treatment process used, size of facility, and treated water quality. Parameters reported include turbidity, microbial contamination, trihalomethane, temperature, pH, conductivity, colour, and ammonia. Plant operating practices, sampling routines, and chemical dosing strategies are also reported.

Book Description
Report to the federal ministers of Environment and Indian & Northern Affairs, Alberta's Minister of Environmental Protection, and NWT's Minister of Renewable Resources. Summarises the main scientific findings of the Northern River Basins Study, which was established to examine the relationship between industrial, municipal, agricultural, and other development and the Peace, Athabasca, and Slave River basins. Reviews the characteristics of the northern river basins and their peoples, the organisation of the Study, and major findings in the areas of environmental overview, use of aquatic resources, traditional knowledge, flow regulation, fish distribution and habitat, nutrients, dissolved oxygen, contaminants, drinking water, ecosystem health, modelling, human health, and cumulative effects. Recommendations by the Study Board, First Nations, and scientific advisors regarding such issues as basin management, monitoring, research, public participation, and a successor organisation are then presented. Also includes a summary of opinions, suggestions, and recommendations expressed at 17 community workshops held throughout the northern river basins area.

Book Description
Report of a study, 1993, in which fish from two traditional winter harvest sites, Hook Point and Bustard Island (west end of Lake Athabasca) were collected and examined for possible contamination from uranium mine-mill operations around the lake.
