Book excerpt: 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.

This book was released on 1996 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Presents the analytical results and spatial trends for the following contaminants in bottom sediment samples collected from northern Alberta rivers in 1994-95: polychlorinated dibenzo-p-dioxins, dibenzofurans, resin acids, polyaromatic hydrocarbons, chlorinated phenolics, polychlorinated biphenyls, extractable organic halides, toxaphene, and mercury. Sampling locations were chosen to provide broad coverage of both the Athabasca and Peace river basins, coverage of key mixing zones downstream from four pulp mills, and replication with locations sampled previously. The 1994-95 survey objectives included: determination of within-site variability in bottom sediment contamination; testing of the assumption that the sand fraction is not an important repository of contaminants; and providing a data set for comparison with earlier bottom sediment collections in 1988-89 and 1992.

Book excerpt: Describes field and analytical methods, and presents results, from a reach-specific study of 200 kilometres of the Athabasca River between Hinton and Whitecourt. This section of the river receives municipal effluent from Hinton in addition to pulp mill effluent. Results are presented for water, suspended sediment, and bottom sediment samples collected in 1992. Contaminants studied include dioxins, furans, chlorinated phenolics, resin acids, organochlorine pesticides, and metals. The data presented will be incorporated into a synthesis report addressing the distribution of contaminants within northern Alberta rivers.

Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: The primary objective of this study was to collect and analyse high quality, well-described sediment cores for use in defining the depositional history of sediment-bound contaminants in Lake Athabasca, including those which have atmospheric or upstream sources. The researchers dated the cores using the lead and caesium methods, and used these geochronological results to determine sedimentation rates and time scales, as well as the suitability of the cores for subsequent contaminant analyses. Selected cores were to be analysed for particle size distribution, bulk carbon and nitrogen species, radionuclides, total polychlorinated dioxins and furans, heavy metals, polynuclear aromatic hydrocarbons, fatty acids, and biogeochemical marker parameters derived from alkanes and fatty acids. Results presented include trends in contaminant concentrations over the past century, correlations of observed trends with human activities or natural occurences, and likely sources of sediment contaminants.

Book excerpt: Examines the mechanisms of natural riverine sediment production in the Northern River Basins Study area, together with the routine data for suspended sediment in the area's rivers, as background for the examination of sediment-associated contaminants. Topics examined include: the causative mechanisms and boundary conditions affecting the sediment regime, including area topography, geology, and hydrology; availability and adequacy of data on suspended sediments in the area; time trends of fluvial suspended sediment dynamics on a seasonal (open water and ice regime) and annual basis, over the long term, and in critical events; sediment sources, pathways, and fates, and sediment dynamics at basin-wide, reach, and site levels; sediment quality, including sediment-associated characteristics of pulp mill effluents and sediment-contaminant relationships; and implications for sediment-associated contaminants. Recommendations are made for monitoring and assessment of the sediment component of the area's ecosystem.

Available in PDF, EPUB and Kindle. Book excerpt: Describes and presents simulation results using a revised model simulating the fate of contaminants in the Athabasca River. The revised fate model allows predictive sediment transport simulation within the WASP4 model framework, predicts resuspension from hydraulic information supplied by WASP4 and from user-supplied sediment characteristics, and can be applied to different flow conditions without having to re-describe sediment transport rates. Several simulations were run using input files from the original model calibration. Program listings of subroutines are included.

Book excerpt: The objectives of this project were to re-examine sediment toxicity at sites sampled previously on the Athabasca River, including sites in the oil sands area, and to conduct toxicity testing on a number of additional sites on the Athabasca, Smoky, and Peace rivers. Investigators tested suspended and bottom sediment samples using four species of freshwater benthic invertebrates in chronic exposure studies. Endpoints measured included survival, growth (amphipod, chironomid, and mayfly) and reproduction (oligochaete worm). Test results were compared with those using standard reference sediment samples for biological quality assurance.

Book excerpt: The Northern River Basins Study was initiated through the "Canada-Alberta-Northwest Territories Agreement Respecting the Peace-Athabasca-Slave River Basin Study, Phase II - Technical Studies" which was signed September 27, 1991. The purpose of the Study is to understand and characterize the cumulative effects of development on the water and aquatic environment of the Study Area by coordinating with existing programs and undertaking appropriate new technical studies. This report documents field methods and sampling sites in the Upper Athabasca River, northern Alberta, for a study of pollution in river bed sediments and fauna.

Available in PDF, EPUB and Kindle. Book excerpt: Describes and presents simulation results from numerical models of the transport and fate of environmental chemicals in northern Alberta rivers. The models were developed using the USEPA WASP modelling system and were structured as one-dimensional (longitudinal) models with separate, interacting water column and bed sediment compartments. Seven selected organic chemicals were simulated over 1992-93 for the Athabasca River and over 1990-91 for the Wapiti/Smoky River system. Chemicals simulated included 2,3,7,8-tetrachloro dibenzofuran, dehydroabietic acid, and phenanthrene. The models were first calibrated for sodium and total suspended solids. Organic chemicals were simulated using a set of environmental fate constants developed from a literature search, numerical estimation software, and estimation from field data. Results of initial simulations were compared to observed data and adjustments made to selected constants to improve the calibration.

Book excerpt: Presents results of a project that conducted broad-spectrum analyses of water and effluent samples upstream and downstream of major effluent sources on the Athabasca, Peace, and Wapiti-Smoky river systems in northern Alberta. Analytical methods to classify organic constituents in effluents were based on full-scan coupled gas chromatography and mass spectrometry, and all significant compounds were characterized with respect to mass spectra and chromatographic retention indices. Contaminants identified included esters, aliphatic hydrocarbons, and fatty acids.
