AbstractA follow-up to the successful CORES Project (2009-2014), SOURCES (SOurce apportionment Using isotope Ratio Characterization of oil sands Environmental Samples; 2014-2019) is focused on the development and application of geochemical and isotopic methodologies to distinguish between natural and anthropogenic contaminants and to better understand processes controlling their distribution in Northern Alberta's Athabasca oil sands region. The project is divided into research activities centred on airborne and waterborne contaminants. The airborne activity is examining: (A) the impact of contaminants on the forest nitrogen cycle through the study of air (NH3/NH4 and NO3), soils, micro-organisms, and tree stems, rootlets and leaves; and (B) the characteristics of organic contaminants (polycyclic aromatic hydrocarbons - PAHs) in lake sediments and snow. The waterborne activity is focused on the surface water-groundwater interactions in areas potentially impacted by emissions from the large tailings ponds. The main contaminants of concern for the waterborne component are metals and naphthenic acids - a complex mixture of carboxylic acids found naturally in bitumen that become concentrated in oil sands process-affected water. As of spring 2018, all fieldwork required to support this research (both activities) is completed. Analyses on air N species, soil microbiome, nitrogen and nutrients in various compartments of trees and soils, on PAHs in lake sediments and snow, and on metals and naphthenic acids in groundwater and surface water samples are ongoing.
Summary(Plain Language Summary, not published)
The Environmental Geoscience Program (EGP) provides scientific research projects by the Geological Survey of Canada to advance knowledge related to the development of Canada's natural resources. The scientific breakthroughs presented at this annual meeting of the EGP are at the root of responsible resource management by the natural resources sector. The body of research also contributes to the implementation of regulations that protect Canadians and their environment
