A fisheries and water quality survey of ten lakes in the Richardson Tower area, Northeastern Alberta. Vol I: Methodology, summary, and discussion
Download1980
A fisheries and water quality survey was conducted in September 1979 on 10 small lakes (67.4 to 338.9 ha) in the vicinity of Richardson Tower, approximately 140 km north of Fort McMurray, Alberta. The major objectives were: (1) to determine morphometric and water quality characteristics in...

McCart, P. J., Tsui, P. T. P., McMahon, B. R., McCart, J. V.
This study was conducted to determine long-term toxic effects, on selected species of fish and invertebrates, of mine depressurization at concentrations non-lethal in acute toxicity tests. The study also includes chronic toxicity experiments, studies of sublethal effects of groundwater, and a...

Jenkerson, C. G., Hickman, M., Charlton, S. E. D.
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...

The settlement and drainage behaviour of co-mix, or mixtures of waste rock and tailings, are examined in a column study. Three co-mix profiles were observed for settlement, drainage, and pore water pressure response. A fourth profile with waste rock and no tailings was also observed for...

Subaqueous water-rock reactions that occur at the pit wall/lake water interface can affect the pH of pit lakes. Many pit lake water chemistry models neglect subaqueous reactions, which may create inaccurate predictions over time. A mineral quantification method is presented that defines the wall...

Assessment of metal mobility, acid rock drainage production, and toxic effects from weathering of mineralised materials (ie mine-waste piles and outcropping alteration/ore zones) is key in evaluating and mitigating metal mining sites. Many metal- and acid-generating materials at these sites are...

Within the context of acid mine drainage (AMD) associated with mining activities worldwide there has been a tremendous research effort to determine the extent of AMD and assess the influencing factors controlling this process. However, the majority of the current approaches focus on local and...

Oxidation of pyrite and other metal sulfides is accelerated by the activity of acidophilic iron- and sulfur-oxidising microorganisms. The ideal biocide for controlling biocatalysed acid rock drainage (ARD) would be inexpensive, inhibitory toward sulfide-oxidising bacteria at low concentrations,...
