Recent concerns have arisen around deeper groundwater systems due to issues related to unconventional oil and gas development and subsurface waste disposal -- areas which both suffer from data scarcity. The first phase of this project conducted a review of the available data for western Canada to improve our understanding of hydrogeological connectivity. We have selected a number of case studies to represent typical hydrogeological environments of concern and have produced a series of maps and databases to improve our understanding of the hydrogeological settings. Water chemistry has been compiled for various hydrogeological units to improve our ability to fingerprint and differentiate groundwaters. This data has been supplemented by sampling and analysis of water from provincial groundwater monitoring networks and other sampling opportunities from industry. Numerical models have been used to interpret existing physical and chemical hydrogeological data for a series of case studies and has improved our conceptual understanding of these systems. These models constrain the likelihood of significant connectivity between aquifers containing potable and poor quality groundwaters. The methods and findings from these studies have been compared to other regions, both within Canada and internationally, to generalize the findings of this study. The second phase focuses on developing additional case studies within western Canada to test and improve the findings of the first phase. We also seek to develop similar databases for eastern Canada, making use of provincial groundwater monitoring efforts and NRCan's BASIN oil and gas database for eastern Canada.
