Non‐target profiling of bitumen‐influenced waters for the identification of tracers unique to oil sands processed‐affected water (OSPW) in the Athabasca watershed of Alberta, Canada

Abstract: RationaleThe objective of this study was to identify unique chemical tracers of oil sands process‐affected water (OSPW) to enable definitive discrimination of tailings pond seepage from natural bitumen‐influenced waters from the Canadian Alberta McMurray formation.MethodsThe approach involved comparing unknowns from an unprecedented sample set of OSPW (n = 4) and OSPW‐affected groundwaters (n = 15) with natural bitumen‐influenced groundwaters (n = 20), using high‐performance liquid chromatography/electrospray … Show more

“…It is important to reiterate that because the Family A acids are present naturally (Figures 1 and 5), these are unlikely to distinguish groundwater affected by low levels of OSPW. We note that the Milestone et al 52 identifies a small group of unknowns with strong diagnostic potential with postulated structures. Confirmations of these structures may ultimately advance the selectivity and sensitivity of the present methodology to enable future studies that could include measuring exact locations and fluxes of seepage.…”

“…Aliquots (0.5–1.0 mL) were withdrawn and methylated with freshly prepared diazomethane for GC × GC-TOF-MS analysis of monoaromatic acids. The remaining extracts were then adjusted to either 5.0 or 1.0 mL; a 500 μL aliquot was removed, solvent exchanged into methanol, and split evenly for (i) ESI-MS analyses of total NAs with profiling by ESI-HRMS and (ii) untargeted profiling by LC-QToF …”

“…Recent publications have focused on the study of natural groundwater AEOs in comparison to AEOs sourced from OSPW. Sophisticated chromatographic and mass spectrometry techniques, together with complex statistical bioinformatics, have been used for interpretation of results, with the aim of identifying tracer compounds. , The current work is complementary to these methods, but utilizes a different approach, with focus on the tracking of surface receiving water contamination following a breach or spill from a tailings pond. Although this current work is a new approach to WSO analysis and source identification, it is a methodology commonly accepted internationally for oil spill forensic identification of spill sources.…”
