Analyses are given for up to 12 metals and 4 pesticides with PCBs, of aquatic environment from 15 study sites along or near the Athabasca River from Fort McMurray north to the confluence of the Peace and Slave Rivers. There were 560 fish (8 species), 15 water, 14 sediment and a few phyto-plankton...

Vanadium concentrations of 2.4 to 5.6 mg/L were lethal in 7 days to rainbow trout of wet weight 1.2-6.2 g. The LC50 varied slightly over the 12 combinations of water quality, from hardness 30 to 350 units and pH 5.5 to 8.8. The 7-day LC5O may be estimated by the following equation, which...

Mine depressurization water obtained from five wells on Lease 17 held by Syncrude Canada Limited, was examined for chemical composition and acute toxicity to two species of fish. In the first series of experiments, mine depressurization water was diluted with various proportions of water...

Volume 2 In order to conduct oil sands mining operations in the surface mining region of the Athabasca oil sands deposits, most regions require depressurization of the basal sandstone formations. The groundwater produced by depressurization operations is of poor enough quality to be toxic to...

Seasonal and areal variations in significant water quality parameters in the Muskeg River basin of northeastern Alberta are described. Specific conductances and the concentrations of major ions (Ca+2, Mg+2, HCO3 -, and, to some extent, Na+ and Cl-) generally exhibited relatively stable seasonal...

Aquatic biophysical inventory of major tributaries in the AOSERP study area Vol I
1980
This report summarizes and compares the physical characteristics of nine streams within five watersheds (Firebag, Muskeg, Steepbank, MacKay, and Ells) in the AOSERP study area. The distributions and relative abundances of fish in each stream and watershed are also described and related to the...

Aspects of the hydrologic and sediment regimes of the Muskeg River basin and the consequences of vegetation removal
Download1983
In a near-natural state the aptly named 1520 km2 Muskeg River basin in northeastern Alberta has an average annual water yield of 94 mm, (20 percent of the precipitation), and an average annual sediment yield of 3210 tonnes (2.20 t/km2) which is derived almost exclusively from channel and riparian...

The present and proposed industrial development associated with the Athabasca Oil Sands has resulted in a need to evaluate the Athabasca River transport and assimilation of contaminants and water occurring substances. Since the beginning of AOSERP in April 1975, water quality and quantity data...

MacDonald, G., Radermacher, A.
The calibrated DOSTOC, NUSTOC and UNSTOC models from 1989 were used effectively to simulate measured 1990 Athabasca River water quality. Changes in effluent loadings at the two pulp mills and an increase in river flows in the lower Athabasca Basin accounted for some noticeable improvements in...
