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...

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...

Microcosm Evaluation of Community Level Physiological Profiling in Oil Sands Process Affected Water
Download2012-11-02
Eaton, B., Humphries, D., Davies, J.
A microcosm-based experiment was conducted to investigate the ability of community level physiological profiling (CLPP) to detect changes in an aquatic microbial community resulting from exposure to oil sands process affected water (OSPW). Detection of the microbial response was done by using...

Oil Sands Mature Fine Tailings Consolidation Through Microbial Induced Calcite Precipitation
Download2014-12-21
Liang, J., Liu, Y., Deng, L., Guo, Z.
The accumulation of mature fine tailings (MFT) in tailings ponds has been a concern of the oil sands industry and regulators for decades. Previous studies and current practices for fine tailings consolidation focus on the addition of inorganic and organic additives to reduce MFT production and...

Liang, J., Gamal El-Din, M., Estrada, L.P., Tumpa, F., Liu, Y.
The accumulation of mature fine tailings (MFT) in tailings ponds with very slow natural consolidation rate has been a concern for decades. Previous studies and current practices for tailings consolidation focus on the addition of various inorganic and organic additives to reduce MFT production...

Review of Health Effects of Naphthenic Acids: Data Gaps and Implications for Understanding Human Health Risk
Download2012-04-11
Gamal El-Din, M., Kindzierski, W., Jin, J.
Oil sands mining involves removal of water from the Athabasca River basin in northeastern Alberta. Water produced during the extraction of bitumen from oil sands is referred to as oil sands process water (OSPW). Information on the likelihood of human exposure to OSPW derived naphthenic acids...
