Description

The objective of this report is to determine whether the ecological effects of treated bleached kraft pulp mill effluent on aquatic invertebrates vary with water temperature. To address this objective, we initially summarized existing studies that evaluated the interactive effects of water temperature on the toxicity of a variety of compounds to aquatic invertebrates. This review indicated that there is a moderately large amount of information indicating that toxic effects of contaminants or other physicochemical stressors can vary with water temperature. These interactive effects between contaminant concentrations and water temperature raise the issue of whether toxic effects of pulp mill effluents that are typically evaluated at 15oC to 20oC, are representative of those at lower temperatures. This is relevant to rivers receiving pulp mill effluent in Alberta, which have lowest dilution capacity in winter, when water temperatures are near 0oC for five months or more. Our review of...

Sediment oxygen demand during the winter in the Athabasca River and the Wapiti-Smoky River system, 1990

Description

Sediment Oxygen Demand (SOD) is an important variable in the oxygen balance of rivers, in particular during the winter under low flow and extensive ice-cover. In 1989, a method to measure SOD... More ≫

Description

Sediment Oxygen Demand (SOD) is an important variable in the oxygen balance of rivers, in particular during the winter under low flow and extensive ice-cover. In 1989, a method to measure SOD in-situ was developed and used to measure winter SOD rates in the Athabasca River. The main objectives of the 1990 study were to determine if SOD rates increased over the winter and to determine the longitudinal trend of SOD in the Athabasca River and the Wapiti-Smoky River system.

The proposed Alberta-Pacific pulp mill : report of the EIA Review Board

Although the proposed mill would be one of the least polluting bleached kraft pulp mills in the world, and even though it would have economic benefits associated with it, the Review Board... More ≫

Description

Although the proposed mill would be one of the least polluting bleached kraft pulp mills in the world, and even though it would have economic benefits associated with it, the Review Board recommends that it not be approved at this time. The major reason for this recommendation is the effluent which would be discharged to the Athabasca River, and in particular, its content of chlorinated organic compounds and the cumulative effects this effluent and that from other mills would have on the Athabasca-Peace River system. The Alberta-Pacific would use technology which would reduce the chlorinated organic compounds to a low concentration. However, the limited available data indicate that there are already measurable amounts of dioxins and furans in fish in the river system near existing mills and extending to more than 1000 km downstream.

Description

Proposed and existing pulp mill developments in the Athabasca River Basin impact on winter dissolved oxygen conditions in the rivers that receive their effluent. In 1987, Alberta Environment started using water quality models to simulate dissolved oxygen levels. This information was used to formulate effluent standards and for management of basin water quality. This report describes the theory of air to liquid gas exchange, methods to measure reaeration, the procedure designed to measure under ice reaeration, results of the field study, and conclusions from the study.

Description

In 1988, the Environmental Quality Monitoring Branch, Alberta Environment, initiated a baseline survey of water quality in the Pease River system. Based on data collected for the survey, a preliminary evaluation of the impact of the existing pulp mill effluents on the Peace River in Alberta is provided in this report.
