AbstractThe glaciated Phanerozoic basin of southern Ontario supports 40 % of the Canadian GDP, has 87 percent of the Ontario population, and over 2 million people rely on groundwater, as does significant components of the agricultural industry (e.g., Sharpe et al. 2014). The province has just completed a decade long, 250 million dollar source water protection program focused on municipal wellhead protection (ref). Nevertheless, there remains no regional framework for managing natural resources, including water, which is a necessary part of the infrastructure of a modern high intensity economy. Within the Canadian federal governance structure groundwater and surface-water are generally a provincial responsibility. Provincial regulations are enforced by the Ministry of Environment and Climate Change (MOECC). Geoscience support for groundwater is provided by the Ontario Geological Survey (OGS). Under the Clean Water Act, Conservation Authorities are the local authorities responsible for groundwater at a watershed scale. A large amount of data is also managed by municipalities through technical documentation of municipal well fields and planning process requirements. The groundwater management structure is fragmented and lacks a unifying science based framework.
The Geological Survey of Canada collaborates with provincial geological surveys under the Interprovincial Geosciences Accord (ref). The work discussed in this paper was completed as part of the 2014-2019 OGS ¿ GSC collaborative groundwater project (e.g., Russell and Bajc, 2015; Russell and Dyer, 2016). The development of this project was in part guided by a gap analysis completed by the OGS and GSC in the winter of 2015 (Russell et al. 2015).
This paper reviews the development of regional geological three-dimensional models for the 72,000 km2 area of southern Ontario. It highlights some of the initiatives by both the OGS and GSC on specific components of such a framework, for example, geochemistry and physical attributes.
