| Résumé | (disponible en anglais seulement)
Ontario implemented the Clean Water Act in 2006 and embarked upon a ten year Source Water Protection (SWP) program that invested ~250 million dollars to
establish a framework to protect municipal water supply. Groundwater studies were conducted at several scales from the well-head protection zone of a municipal well to watershed characterization reports of a source protection region. There has been
little attempt; however, to integrate these results into a Southern Ontario scale geologic or hydrogeologic framework. As such, these studies can be considered to be under-utilized regional hydrogeological assets which could contribute to a broader
understanding of regional hydrostratigraphy and hydrogeology. For example, relating municipal wells to a geological understanding could support improved characterization of aquifer geometry, architecture and hydrogeologic properties. More broadly,
there continues to be an opportunity to integrate not only SWP information but data from Permits to Take Water and the Provincial Groundwater Monitoring Network (PGMN) into a more comprehensive, standardized, regional hydrostratigraphic
framework.
This presentation is a status report on a geological co-ordination activity that will preview selected areas of the hydrostratigraphic framework. In particular, we highlight geological model development to support an improved framework
and analysis of the related hydrogeological datasets. Work is advancing on the capture of high-quality control datasets such as measured field sections, borehole records and hydrostratigraphic classification. All Ontario Geological Survey 3D models
have been integrated in a single model environment along with the regional Oak Ridges Moraine model. Progress has been initiated on the hydrostratigraphic classification of wells in the PGMN with an initial focus on wells screened in surficial
deposits, and located in areas of controlled 3D geological models and areas with abundant high-quality datasets. Progress has also been made on mining SWP program data for municipal well fields. Current data mining is focused on relating municipal
well data to defined aquifers.
Geological models that can be used to support the above hydrogeological frameworks are now available for portions of the GTA including, at variable scales, ORM, Simcoe County and the Yonge Street aquifers. We preview
these steps to the eventual development of a regional conceptual 3D hydrogeological model for southern Ontario. |
