Download or read book Contribution of Industrial, Municipal, Agricultural and Groundwater Sources to Nutrient Export, Athabasca, Wapiti and Smoky Rivers, 1980-1993 written by Patricia A. Chambers and published by The Study. This book was released on 1996 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this report is to assess the sources of nitrogen and phosphorus to the Athabasca and Wapiti/Smoky rivers and evaluate the need to consider groundwater contributions when undertaking simulation modelling of chemical parameters of the Athabasca River during winter. To address the first objective, longitudinal trends in nitrogen and phosphorus were examined for each river system in relation to point source inputs and the contributions of anthropogenic point sources and agricultural activity in the rivers' nutrient loads were quantified. The importance of groundwater during winter was assessed by examining hydrologic mass balances and changes in dominant ion proportions. Results are presented of analyses of long-term values of nutrients from ten sites on the Athabasca and three sites on the Wapiti/Smoky rivers.

Book Synopsis Canadian Guidance Framework for the Management of Phosphorus in Freshwater Systems by : Canada. National Guidelines and Standards Office
Download or read book Canadian Guidance Framework for the Management of Phosphorus in Freshwater Systems written by Canada. National Guidelines and Standards Office and published by Environment Canada. This book was released on 2004 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document presents a guidance framework for the management of phosphorus in freshwater systems. The introduction reviews the development & validation of this framework. Chapter 2 presents a review of the scientific literature on phosphorus in the aquatic environment, including properties, sources, fate, sediment interactions, parameters affecting phosphorus availability, trophic status, & effects on organisms. Chapter 3 examines a number of approaches used by other jurisdictions for setting phosphorus guidelines. Chapter 4 outlines the proposed framework-based approach for phosphorus management in which water bodies are marked for further assessment by comparing their trophic status to predefined ranges of phosphorus concentration. Chapter 5 summarizes some of the recommended assessment options currently use in Canada & other jurisdictions. Chapter 6 reviews management options that can be considered once the phosphorus concentrations have been assessed & compared to original goals for the water body. The final two chapters present case studies of implementation of this framework at Lake Simcoe in Ontario and at Kodiak Lake, Northwest Territories.
Book Synopsis Identification of Spatial and Temporal Patterns in Nutrient Limitation with Herbivory Effects, Wapiti, Smoky and Athabasca Rivers, 1994 by : Garry J. Scrimgeour
Download or read book Identification of Spatial and Temporal Patterns in Nutrient Limitation with Herbivory Effects, Wapiti, Smoky and Athabasca Rivers, 1994 written by Garry J. Scrimgeour and published by The Study. This book was released on 1996 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding the effects of nutrients on the aquatic environment will be critical for managing industrial and municipal effluent discharges in northern Alberta rivers. One objective of this study was to identify spatial patterns of nutrient limitation in the Wapiti-Smoky and Athabasca river systems, which receive a diversity of effluent discharges including municipal sewage, agricultural runoff, and effluent from oil sands and pulp mills. Investigators conducted two experiments to accomplish this goal: identification of the interactive effects of both nutrient enrichment and grazing by aquatic insects (herbivory) on algal biomass, using nutrient diffusing substrata (NDS) downstream of the Hinton combined effluent; and using NDS to quantify large-scale patterns in algal biomass and nutrient limitation upstream and downstream of the major effluent and tributary input sources along the three rivers. NDS placed at 33 sites aided in the identification of river reaches having no nutrient limitation and those having some form of nutrient limitation.

Book Synopsis Nutrient Enrichment in the Peace, Athabasca and Slave Rivers by : Patricia A. Chambers
Download or read book Nutrient Enrichment in the Peace, Athabasca and Slave Rivers written by Patricia A. Chambers and published by Canadian Government Publishing. This book was released on 1996 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Synthesises results from research and monitoring studies undertaken to characterise nutrient loading from all point and diffuse sources in northern Alberta river basins. Also evaluates the impacts of nutrient loading on river chemistry, assesses the response of riverine biota to nutrient loading from pulp mill and municipal effluents, quantifies nutrient responses of benthic biota, and investigates interactions between nutrients and contaminants in pulp mill effluents on food webs. The findings are used to assess the state of aquatic ecosystem health and to develop scientific and management recommendations for the northern river basins.

Download or read book Contaminant Fate Modelling, Athabasca, Wapiti and Smoky Rivers written by Golder Associates and published by . This book was released on 1996 with total page 482 pages. 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.
