AbstractThis regional hydrogeological study of the Chateauguay River watershed was undertaken during a four-year period, between 2003 and 2007, and required the involvement of several multidisciplinary groups. The rationale for the study was the lack of knowledge on the state of the groundwater resource, which hindered management efforts in the watershed. The project objective was to define the major aquifer units and the quality and quantity of the groundwater resources. The applied methodology consisted of compiling existing data and generating a digital database, acquiring new field data, and updating geological maps, followed by determining the hydrodynamic and hydrogeochemical processes, and assessing the sustainability. The regional aquifer units are comprised of sedimentary bedrock formations and occasional coarse fluvioglacial sediments. The nature and thickness of the surficial deposits defines the hydrogeological settings and flow regimes.
