520 |a"This report documents the geochemical and isotopic analyses that have been carried out within the framework of a project aiming to assess the potential impacts of shale gas activities on shallow aquifers of the Saint-Édouard area, in the province of Québec. A large part of the St. Lawrence Platform, in which the Saint-Édouard study area is located, is underlain by the Utica Shale, which was the target for shale gas exploration activities between 2006 and 2010. The fact that the Saint-Édouard well was found to be the most promising gas well during this period, and that dissolved methane was found to be ubiquitous in shallow groundwater of this study area, were some of the reasons why this study area was selected. The project was multi-disciplinary, combining geological, geophysical, geomechanical, hydrogeological and geochemical aspects. The geochemical study proved to be critical, providing key information on the origin of hydrocarbons found in groundwater, and supporting conclusions regarding the low potential for upward fluid migration from the Utica Shale to shallow aquifers. Both groundwater and rock samples were collected. Groundwater analyses comprised conventional geochemical analyses (concentrations of major and minor ions, trace metals), as well as isotopic analyses on water, dissolved inorganic carbon, alkanes, chloride, and radon. This Open File describes in detail the methods used to carry out fieldwork and laboratory analyses. The Open File is meant to document all geochemical data obtained during the 4-year project within a single document, with a level of detail that was not possible in the scientific papers related to this project"--Summary, page v.
