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.

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

Proctor and Gamble Cellulose Ltd. Operates a bleached kraft pulp mill near Grande Prairie, which discharges effluent to the Wapiti River. In the late 1970’s water quality impacts and public complaints began to arise with respect to the Smoky River, into which the Wapiti drains. Since little data were available for the Smoky, a water quality study was carried out in 1983 to assess the impact of the pulp mill and to augment the data base and understanding of the Smoky River system.
