Abstract
Groundwater is an important resource for many of Ontario’s residents. In recent years, the recognition of the need to protect existing groundwater resources has increased substantially. Numerous pieces of legislation have been or are being introduced that focus on the protection and utilization of the provinces groundwater resources. Identification of groundwater aquifers is an important component of any protection or source water initiative. A critical component of mapping groundwater aquifers is a thorough understanding of the threedimensional (3D) distribution of Quaternary (surficial) sediments. The 3D distribution of these sediments form recharge and discharge zones, local and regional aquitards and aquifers. Accurate 3D models will allow new aquifers to be located and the estimation of volume of groundwater resources. Of equal importance, the models can be used to identify aquifers susceptible to contamination and potential pathways for contaminants. This report provides an update of a multi-year project aimed at the construction of a 3D geologic model of Quaternary sediments in the Barrie area using Datamine Studio®: a software package developed for the mining industry. New software scripts have been written to adapt the software to overburden mapping for groundwater modelling applications (Bajc and Newton 2005). The modelling software has many inputs including data from drilling and associated downhole geophysics, seismic surveys, drilling logs, water well records, the interpretation of natural and man-made exposures, published surficial maps and a digital elevation model (DEM). The Barrie area modelling project is following the protocols and procedures established for a similar project that has been undertaken in the Waterloo region (Bajc and Newton 2005; Burt and Bajc 2005). The glacial history and surficial geology of the study area has been described and discussed in several previous publications (Barnett 1988, 1997; Finamore 1981; Finamore and Bajc 1984; Gwyn 1972; Burt 2004; Burt and Russell 2005; Slattery 2003); detailed descriptions, visual logs, laboratory results and photos of the 2004 drilling program have been released on CD-ROM (Burt and Russell 2006). The latter portion of this report is focussed on the results of the 2005 and early 2006 drilling programs.
