Description

This report highlights the findings from surveys conducted on the lower Pembina River system in the fall, 1993 and winter, 1994. The purpose of the survey was to describe basic water quality conditions on this stretch of the river, including major tributaries; to obtain pertinent to low flow conditions and to winter inputs to the Athabasca River; and to obtain data pertinent to potential flood control options.

Investigations of streambed oxygen demand, Athabasca River, October 1994 to March 1995

Description

Streambed oxygen demand (SOD) is thought to account for a significant fraction of the total oxygen demand in the Athabasca River in the winter. SOD was sampled in the Athabasca River from October... More ≫

Description

Streambed oxygen demand (SOD) is thought to account for a significant fraction of the total oxygen demand in the Athabasca River in the winter. SOD was sampled in the Athabasca River from October 1994 to March 1995 with objectives of obtaining a series of measurements from upstream of Hinton to the Calling River area, and investigation temporal change in SOD at key sites.

Description

Adsorbable Organic Halide (AOX) has become an accepted measure of chlorinated organic material, and is used to monitor and regulate bleached Kraft pulp mill effluents. Two surveys on the Wapiti-Smoky river system and on the Athabasca River were carried out in 1989-90 to assess the presence and downstream persistence of AOX.

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.
