Assesses the utilization and quality of the different non- conventional sources of drinking water used by people in the Northern River Basins Study area. Such sources include rain water, melted snow or ice, untreated surface water, dugout water, groundwater, bottled water, and water treated by various point-of-use technologies. The assessment included a literature review on non-conventional drinking water sources, drinking water quality, and the correlation between drinking water and health; interviews with area residents on their non-conventional drinking water practices; collection of field samples of non-conventional drinking water and analysis of samples for various physical, chemical, and microbiological parameters; and research on the effectiveness of some of the portable point-of-use drinking water treatment filters on the market.
Lists Northern River Basins Study technical reports by issue number, subject, and geographic area studied. Subject areas used to classify the reports are: hydrology/hydraulics, nutrients/dissolved oxygen, contaminants, food chain, drinking water, other uses, traditional knowledge, and synthesis and modelling. Ten geographic divisions are used: three each for the Athabasca and Peace Rivers, and one each of the Wapiti/Smoky rivers, Peace-Athabasca Delta, Lake Athabasca, and Rivière des Rochers/Slave River.
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.
The NTBS was designed to address the ecological concerns about pulp mill expansion, and to increase scientific knowledge about environmental conditions [ecology, ecosystem sustainability, water pollution and control, habitat, effect on fish and fishing, etc.] in the major river systems of the north. The study's objectives were to gather and interpret sound scientific information about the basins, develop appropriate recommendations for basin management, and communicate effectively with the public. The government response report confirms the governments' commitment to ecosystem sustainability and to pollution control in northern rivers. First Nations and Metis aboriginal [native] peoples contributed significantly to the NRBS.
The purpose of this study was to determine the potential for off-flavour tainting of water and/or fish in the Athabasca River by compounds discharged from pulp mills. Three different analytical methods commonly used in monitoring for the presence of odorous compounds in water supplies are described and results are presented: odour characterization by a trained flavour profile panel; olfactory gas chromatography; and gas chromatography/mass spectroscopy. The usefulness of each method in providing different types of information is noted. The results are compared with those of an earlier survey to indicate the impact of combined effluents at Hinton on the odour of the Athabasca River.
An important component of the Northern River Basins Study was the original data resulting from the collection and analysis of environmental samples. Samples were collected, stored, and analysed by a number of different agencies, and an inventory of samples obtained by the Study and results data were compiled into a single electronic database to ensure future ease of access to the original data. This report describes the data contained in the database, the methods used to compile the database, the media and the nature of the samples, the collection site, and the data collected. Information is provided on which analyses were conducted on samples as well as the values of various parameters measured for the samples. All the files and the data fields that comprise the database are described in the users' guide in the report appendix.
Provides a literature review of the current state of knowledge in the area of inorganic chemical removal from drinking water. The review considers inorganic chemical parameters that include arsenic, barium, boron, cadmium, chloride, chromium, copper, cyanide, fluoride, iron, lead, manganese, mercury, nitrate, selenium, sodium, sulphide, total dissolved solids, uranium, and zinc. Sources of inorganic chemicals include industrial and municipal effluent, agricultural runoff, and natural sources. Both conventional and advance treatment processes are noted to give an idea of how each contaminant could be removed. These processes include coagulation, softening, filtration, oxidation, adsorption, ion exchange, distillation, membrane processes, aeration, and dilution.
Reviews the literature concerning the current state of knowledge of removing organic chemicals from drinking water. Such chemicals may include humic substances produced by degradation of plant and animal matter, contaminated leachate from landfills and lagoons, agricultural runoff, and accidental and illegal dumping of chemicals. Treatment techniques reviewed include coagulation, softening, sedimentation, filtration, chlorination, adsorption on activated carbon or resins, air stripping, reverse osmosis, and the use of oxidants or ultraviolet radiation.
This report reviews the various water treatment technologies available to remove micro-organisms from raw water supplies. Discussions of each technology includes a process overview, performance information, design considerations, operating and maintenance aspects, and notes on costs and status of technology development. In addition, the impacts of important micro-organisms and relevant regulations are examined to highlight the significance and requirements of removing micro-organisms from water treatment processes. Specific consideration is made regarding those technologies suitable for small community systems located in the Northern River Basins Study area. Types of technologies examined include pre-filtration processes such as coagulation and sedimentation, filtration, and disinfection. Three types of package plants (conventional, tube-type clarification, and adsorption clarifier) suitable for small communities are also reviewed.
