Preliminary compatibility studies of G.C.O.S. sand tailings pond water with Athabasca River
Download1968
Alberta Health, Environmental Health Services Division
On May 30, 1968 G.C.O.S requested permission to discharge 110 x 106 ft3 of effluent from the sands tailings pond at the Fort McMurray site into the Athabasca River during periods of high river flow. G.C.O.S. outlined the events which made this request necessary in order that an adequate base be...

Some methods for treating tar sands tailings: Part 1 - laboratory application of CO2 process and related testing of type "X" treatment
Download1973
This report concerns some methods whereby the liquid waste from plants using the Clark hot water process to extract bitumen from tar sands is rendered clean. This report describes some novel experiments on liquid tailings from the G. C. O. S. plant, which may lead to an economically feasible...

Acute lethality study of G.C.O.S. dike filter drainage using rainbow trout and brook sticklebacks
Download1976
When evaluating this data, lethality (i.e. death of the organism) is the symptom being observed. Acutely lethal refers to a sample killing 50% of a population after 96 hours exposure. 1. The dike filter drainage was found to be acutely toxic to both rainbow trout and brook sticklebacks. The...

Oil sand overburden characterization within the mine area of Syncrude Lease No. 17 for reclamation of spent oil sand
Download1976
For the establishment and growth of plants, spent oil sand lacks Ca, K, NO3-N, available P, Zn, CEC and available water storage capacity. Cu, Mn and possibly SO4-S are marginally adequate in spent sand. Oil sand overburden materials within the mine area of Syncrude Lease No. 17 were sampled and...
