  abstract = {{G}eochemical tracers have the potential to provide valuable insights for constructing conceptual models of groundwater flow, especially in complex geological contexts. {N}evertheless, the reliability of tracer interpretation hinges on its integration into a robust geological framework. {I}n our research, we concentrated on delineating the groundwater flow dynamics in the {I}nnisfil {C}reek watershed, located in {O}ntario, {C}anada. {W}e amalgamated extensive hydrogeological data derived from a comprehensive 3{D} geological model with the analysis of 61 groundwater samples, encompassing major ions, stable water isotopes, tritium, and radiocarbon. {B}y seamlessly incorporating regional physiographic characteristics, flow pathways, and confinement attributes, we bolstered the efficiency of these tracers, resulting in several notable findings. {F}irstly, we identified prominent recharge and discharge zones within the watershed. {S}econdly, we observed the coexistence of relatively shallow and fast-flowing paths with deeper, slower-flowing channels, responsible for transporting groundwater from ancient glacial events. {T}hirdly, we determined that cation exchange stands as the predominant mechanism governing the geochemical evolution of contemporary water as it migrates toward confined aquifers situated at the base of the {Q}uaternary sequence. {F}ourthly, we provided evidence of the mixing of modern, low-mineralized water originating from unconfined aquifer units with deep, highly mineralized water within soil-bedrock interface aquifers. {T}hese findings not only contribute significantly to the development a conceptual flow model for the sustainable management of groundwater in the {I}nnisfil watershed, but also offer practical insights that hold relevance for analogous geological complexities encountered in other regions.},
