AbstractThe characterization of groundwater hydrogeochemistry of the regional county municipalities of Argenteuil, Mirabel, Deux-Montagnes, and Thérèse-de Blainville is underway as part of a regional hydrogeological mapping project of the fractured aquifers of southwestern Quebec. The goal of the hydrogeochemistry component is to eval- uate regional groundwater quality and identify geochemical processes controlling this quality. Three sampling campaigns were conducted, one in spring 1999, one in summer 1999, and another in summer 2000. Preliminary results of the measurement of physico-chemical parameters and the analysis of groundwater samples for inor-ganic and isotopic (stable isotoped 18 O) concentrations reveal significant variations in groundwater geochemistry. These variations seem to be controlled in part by geological units and by hydrogeological context. Moreover, pre- cipitation was analyzed for stable isotopes to establish the local meteoric waterline for the area. This will help understand the origin of groundwater.
