ABSTRACT: A groundwater study is being carried out in southern New Brunswick to assess the potential link between gas reservoirs and the shallow fractured rock aquifer. Fieldwork included the drilling of ten shallow monitoring wells, hydraulic tests in wells open in the rock aquifer, permeameter tests in surficial deposits and continuous water-level recording. Hydrogeological conditions were defined based on the analysis of existing and acquired data, allowing the development of a piezometric map and a 2-D numerical model representing deep groundwater flow in the hydrogeological system that includes the intermediate zone located between gas reservoirs and shallow rock aquifers. Most of the active gravity-driven groundwater flow was found to occur in the first 100 m of the unconfined rock aquifer.
RÉSUMÉ: Une étude hydrogéologique est présentement réalisée dans le sud du Nouveau-le lien potentiel entre des réLes travaux de terrain ont inclus le forage de dix peu profonds, des essais hydrauliques dans les puits ouverts au roc, des essais au perméamètre dans les sédiments de surface et un suivi piézométrique continu. Les conditions hydrogéologiques ont été définies à de développer une carte piézométrique et un modèle numérique lement système hydrogéologique qui comprend la zone intermédiaire entre les réservoirs gaziers et les aquifères superficiels dans le roc fracturé.
