ABSTRACT: The objective of this project is to assess potential impacts of shale gas activities on shallow groundwater via upward fluid migration. The study area is located in the Sussex region, in southern New Brunswick. Since very few data are available on the intermediate zone, located below shallow aquifers and above gas reservoirs, indirect multi-source data from five disciplines were integrated to provide a better understanding of the system. Dissolved methane in groundwater shows ambiguous isotopic composition. However, the geochemical interpretation based on multiple samples from regular monitoring seems to point towards a microbial origin for most of them. Geomechanical properties indicate that the intermediate zone acts as an efficient barrier to protect shallow aquifers.
