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

Pulp mills discharge significant amounts of wastewater which have the potential to affect water quality in receiving waters. The Alberta-Pacific Environmental Impact Assessment Review Board has been established to examine the potential water quality impacts of pulp mills in the Peace and Athabasca River systems. Alberta Environment has monitored water quality in these rivers for a number of years and has carried out assessments of the impact of existing pulp mill effluents on river water quality and aquatic biota. It is the purpose of this document to outline the monitoring done to date, to summarize the findings of these assessments regarding pulp mill effects, and to indicate the direction of future river monitoring and assessments.

Description

This report identifies historical, annual and open water, low flow sequences for 13 stations in the Athabasca River Basin. Frequency curves are developed which provide an estimate of droughts of a specified exceedance probability. Drought events recorded on the Athabasca River below McMurray with an exceedance probability greater than 0.90 are identified and discussed. The analysis provides low flow information which can be used to determine general management guidelines for the Athabasca River Basin.
