Description

This study investigates key issues identified in the Joint Canada-Alberta Oil Sands Monitoring program regarding water quality of tributaries to the lower Athabasca River, specifically: the current state of water quality; the distribution of contaminants; whether the presence of toxic substances is increasing or decreasing, and their rate of change' and whether substances added to the rivers by natural and man-made discharges are likely to cause deterioration of water quality.

A dyke failure on the Obed Mountain Mine site in the Hinton region on October 31, 2013 caused the release of an estimated 670,000 cubic metres of process water and suspended sediment into the... More ≫

Description

A dyke failure on the Obed Mountain Mine site in the Hinton region on October 31, 2013 caused the release of an estimated 670,000 cubic metres of process water and suspended sediment into the Apetowan and Plante Creeks. These creeks merge into the Athabasca River downstream of Hinton. A number of government departments and agencies have actively been involved in responding to this event. This preliminary report summarises the first week of analytical sample data collected by Environment and Sustainable Resource Development (ESRD) and analysed by both ESRD and Alberta Health Services. Current near real-time turbidity data is also included.

Description

Since the early 1950s, large rivers throughout the Province of Alberta have been subjected to regular monthly sampling for a broad suite of water quality parameters. Althought water quality monitoring on the Athabasca River began as early as 1955 for some variables, regular sampling for most parameters was not implemented until at least 1960. Initially, sampling efforts were limited to a single station at the Town of Athabasca. In 1977, a second site was established at Old Fort, 200 km downstream of Ft. McMurray. Two additional sampling stations, situated upstream of both Hinton and Fort McMurray, were added in 1999 and 2002 respectively. The purpose of this report is to provide both a general overview of water quality conditions in the Athabasca River, in the form of summary statistics and time series graphs for all four sites, and more in-depth statistical trend analyses on long-term data for the Athabasca and Old Fort monitoring stations.

Description

This report presents the findings of water quality monitoring and surveys on the Athabasca River system by Alberta Environmental Protection in the years 1990 to 1993. Water quality has been monitored by means of longitudinal synoptic surveys, recording meters, and a network of regular sampling sites. The effects of effluents are quantified and evaluated with reference to the Alberta Ambient Surface Water Quality Interim Guidelines and the Canadian Water Quality Guidelines. The results of this set of surveys are compared with previous winter water quality surveys from 1988 and 1989.
