| Résumé | (disponible en anglais seulement)
The mandate of the Ontario Geological Survey is to provide citizens and institutions of Ontario with accurate and objective earth science knowledge about
Ontario, in order to sustain and support quality of life, economic prosperity, environmental quality, and public health and safety. The OGS does not comment on best practices or recommended approaches for reviewing and approving changes to landuse or
development applications in karst terrains. Various Ontario ministries - the Ontario Geological Survey (MNDM) and the Ministry of Natural Resources & Forestry (MNRF), Municipal Affairs and Housing (MMAH), and Agriculture and Food and Rural Affairs
(OMAFRA) have been reviewing existing policies related to land-use and development throughout southern Ontario and Manitoulin Island to update hazard lands guidelines, nutrient management practices and to develop best practices documents for various
forms of development in karst terrains.
The main purpose of the Ontario Geological Survey Karst Mitigation field-based research is to provide a more comprehensive summary of the kinds of geoscience field work and data sets that could be integrated
into field-based studies in order to address gaps in the current guidelines framework (e.g., Natural Hazards Technical Guidance documents for use with the current Ontario Provincial Policy Statement). A "best practices" approach to addressing karst
hazards should be carried out in a staged manner, one that involves a general geologic- and geomorphologic-data-gathering desktop investigation (Phase 1 study) that would progress to a more detailed field-based study (Phase 2) to quantify and qualify
identified karst terrain hazards (i.e., progress from Phase 1- to Phase 2-level site investigation depending upon nature of land use or development project being proposed). An overview of proposed best practices for investigating karst hazards in
Ontario and an innovative "toolkit" for investigating karst-influenced groundwater flow zones will be reviewed in this presentation. |

Procès-verbaux pour la géoscience des eaux souterraines à échelle régionale Organisée par la Commission géologique de l'Ontario, la Commission
géologique du Canada et les géoscientifiques de Conservation Ontario. La journée portes ouvertes est prévue pour 2017-03-01 et 02. L'objectif est l'engagement du public et la diffusion de la géoscience dans le sud de l'Ontario au cours de la dernière
année. |
