Studies concentrating upon the epilithic algal community were conducted in five tributary rivers flowing into the Athabasca river: the Muskeg, Steepbank, Hangingstone, MacKay, and Ells rivers. Numerically, cyanophycean algae (Lyngbya aerugineo-caerulea, Phormidium sp., Calothris braunii, Nostoc...
A longitudinal physico-chemical and algal survey of five rivers flowing through the AOSERP study areaDownload
Studies concentrating upon the epilithon were conducted in five tributary rivers flowing into the Athabasca River: the Muskeg, Steepbank, Hangingstone, MacKay, and Ells rivers. The species composition of the epilithic algae was determined during June to November 1978. Diatoms and blue-green...
A preliminary study of chemical and microbial characteristics of the Athabasca River in the Athabasca oil sands area of northeastern AlbertaDownload
A literature review and evaluation of methods used to determine rates of bacterial uptake (heterotrophic assimilation) of organic substrates in fresh water systems was undertaken. The uptake of a \"universal\" substrate - radiolabelled glutamic acid - was determined in order to assess the effects...
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...
A synopsis of the physical and biological limnology and fishery programs within the Alberta oil sands areaDownload
“A Synopsis of the Physical and Biological Limnology and Fishery Programs within the Alberta Oil Sands Area\" forms a background reference document on the limnology of the AOSER Program study area in northeastern Alberta. Within the report, the following items are discussed and summarized: data...
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...
The purpose of this study was to determine the acute and subacute toxicity of bitumen to rainbow trout. The bitumen was collected along the banks of the Athabasca River downstream of Fort McMurray during 1984. Prior to experimentation, the bitumen was fractionated in water at 35°C, using an...
Acute lethality of mine depressurization water to trout-perch (Percopsis omiscomaycus) and rainbow trout (Salmo gairdneri) Volume IDownload
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...
As a result of industrial development in the Athabasca oil sands area of northeastern Alberta, concerns have been raised regarding potential impacts on surface water quality in the area. It is of particular concern that the cumulative effects of increasing development of the oil sands may create...
