This book was released on 2009 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The purpose of this report is to provide both a general overview of water quality conditions in the Athabasca River, in the form of summary statistics and time series graphs for all four Long-Term River Network (LTRN) sites, and more in-depth statistical trend analyses on long-term data for the Athabasca and Old Fort monitoring stations. Sampling actvities on the Athabasca River have frequently examined a wide range of trace organic contaminant (e.g. pesticides, priority pollutants, chlorinated phenolics, PAH). However, due to limited sampling frequency and relatively few detections, most data associated with these trace contaminants are inappropriate for statistical trend assessment. Analysis of these data is limited to basic summary statistics in this report."--Document.

Investigators obtained SOD measurements at 13 locations from upstream of Hinton downstream to the Calling River. The substrates at these locations were mainly coarse, with pebble, cobble, and boulder predominating. Controlling factors affecting SOD are discussed.
Book Synopsis Water Resources Use and Management Issues for the Peace, Athabasca and Slave River Basins by : Michael Williams
Download or read book Water Resources Use and Management Issues for the Peace, Athabasca and Slave River Basins written by Michael Williams and published by The Study. This book was released on 1996 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: As part of a survey of residents of northern Alberta river basins, respondents were asked to choose the best and worst examples of various sets of threats to water quality/quantity in the basins as well as best and worst examples of possible management actions. This report analyses the responses to the two sets of best/worst questions, using logistic regression. The analysis produced the following estimates: the probability that each of 11 possible threats to water quantity/quality will be selected as the area of most concern; and the probability of each of 11 possible management actions will be selected as the most effective response to such concerns. The probabilities produced by this analysis are ranked to determine the preferences of northern households and various stakeholder groups within the basin.

Book Synopsis Wood Buffalo National Park Water Quality by : Nancy Elizabeth Glozier
Download or read book Wood Buffalo National Park Water Quality written by Nancy Elizabeth Glozier and published by . This book was released on 2009 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "In this report we have presented and interpreted water quality data collected on the Athabasca, Peace, and Slave rivers at the boundaries of Wood Buffalo National Park between August 1989 and December 2006. We have summarized the large amount of water quality data available and provide detailed statistical summaries for the period of record as a reference for further studies and monitoring programs. Patterns in water chemistry among the three watersheds are discussed, including comparisons to upstream source waters. Parameters with national guidelines or site specific objectives for the protection of aquatic life are evaluated for excursions, including metals, major ions, and nutrients. We provide site specific regression analyses for several parameters with suspended sediment concentration as measured by non-filterable residue. We report on the results of statistical temporal trend analyses (seasonal and yearly) conducted for 39 water quality parameters and discuss their relationship to: 1) river discharge, 2) specific time periods, and 3) season. More specific analyses were conducted to examine two issue driven concerns; changes in metal concentration in the Athabasca River, and nutrient concentrations in relation to ecosystem functioning at all stations. Finally, the monitoring program was reviewed for scientific validity, gaps and emerging issues with recommendations provided for ongoing Parks monitoring programs"--Executive summary, page iii.
Book Synopsis Water Quality Trends in the Entiat River Watershed by :
Download or read book Water Quality Trends in the Entiat River Watershed written by and published by . This book was released on 2013 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: A large, multiagency effort is underway in the interior Columbia River basin (ICRB) to restore salmon, trout, and char listed as threatened or endangered under the 1973 federal Endangered Species Act. Water quantity and quality are widely recognized as important components of habitat for these depleted salmonid populations. There is also broad concern about maintaining a high-quality water supply for other societal and ecosystem uses. A particularly active salmonid habitat restoration program is being conducted in the Entiat River, which drains a portion of the eastern slope of the Cascade Mountains in central Washington state. There, routine monitoring by the Washington Department of Ecology identifies pH and water temperature as water quality parameters of concern. In response, the U.S. Forest Service, Pacific Northwest Research Station is testing a more intensive approach to water quality monitoring that uses multiparameter data-logging instruments at four locations to measure fundamental water quality parameters (pH, water temperature, dissolved oxygen, and specific conductivity). This report presents results from the first 4 years of the study and discusses variation in water quality parameters with season, river discharge, and location. We demonstrate that unattended data-logging instruments effectively provide high-resolution data, which facilitate identification of forcing mechanisms such as direct solar radiation, air temperature, and river discharge. Results complement ongoing, broad-scale salmon recovery monitoring by quantifying concurrent changes in water quality. Although exploratory in nature, this study can inform future, more intensive monitoring programs.
