A laboratory study of long-term effects of mine depressurization groundwater on fish and invertebrates
Download1980-01-01
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...

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...

Application of Forward Osmosis Membrane Technology for Oil Sands Process-Affected Water Desalination
Download2014-10-01
The extraction process used to obtain bitumen from the oil sands produces large volumes of oil sands process-affected water (OSPW). As a newly emerging desalination technology, forward osmosis (FO) has shown great promise in saving electrical power requirements, increasing water recovery, and...

Biomonitoring for the effects of air pollution in the AOSERP study area. Report of a workshop
Download1979
This document is a summary of a workshop held on 7-8 June 1979 at the Mayfield Inn, Edmonton, Alberta, in order to provide guidance to the Alberta Oil Sands Environmental Research Program (AOSERP) concerning the establishment of a system to biologically monitor the effects of air pollution in the...

Mian, H., Currie, R., Zhao, B.
The purpose of this report is to identify challenges in analyzing naphthenic acids (NAs) associated with oil sands process water (OSPW). Naphthenic acids are present naturally in oil sands bitumen and have the classical formula CnH2n+ZO2. Within this formula n represents the carbon number and Z...

Characterizing the Organic Composition of Snow and Surface Water Across the Athabasca Region: Phase 2
Download2014-12-15
Gibson, J., Birks, J., Cho, S., Taylor, E., Yi, Y.
This study was conducted to characterize the composition of polar dissolved organic compounds present in snow and surface waters in the Athabasca Oil Sands Region (AOSR) with the goal of identifying whether atmospherically-derived organics present in snow are an important contributor to the...

Designer Biochar-Coke Mixtures to Remove Naphthenic Acids from Oil Sands Process-Affected Water (OSPW)
Download2014-11-27
Alessi, D.S., Alam, M S., Kohler, M.C.
The objective of this 6-month pilot experimental study was to test the ability of biochars derived from Alberta biomass and an oil sands petroleum coke to remove selected organic acids from water. To this end, we selected one biochar produced from wheat straw and made by the Alberta Biochar...

Development of a Novel Engineered Bioprocess for Oil Sands Process-Affected Water and Tailings Fines/Bitumen/Water Separation
Download2014-12-09
Gamal El-Din, M., McPhedran, K., Islam, M.S.
The oil sands bitumen extraction process results in the creation of waste products including oil sands process-affected water (OSPW) and mature fine tailings (MFT). Many technologies are currently under investigation to treat these waste products that are currently contained in vast storage...
