AbstractGroundwater represents an important source of water for agriculture in the Innisfil Creek watershed, southern Ontario, where water vulnerability issues were evident through recent drought conditions. Uncertainties remain regarding the groundwater flow pattern of the multi-layer aquifer system and further understanding is required to plan for sustainable groundwater use. A hydrogeological study based on geochemistry and isotopes (d2H, d18O, d13C,14C-DIC, and 226Ra) is being developed to better characterize and quantify recharge, regional flow patterns, and potential inter-aquifer flow. In this paper, we present on work completed in 2018. The study objectives were to gather existing hydrogeological and geochemical data into a comprehensive database, to analyse the data in order to support targeted additional water sampling, and to develop preliminary interpretations. The ongoing project is now set for the development of an initial conceptual model based on the geochemical and isotopic interpretations combined with statistical analyses and physical hydrogeology processes observed in the region.
