| Résumé | (disponible en anglais seulement)
Numerous groundwater studies, including technical work completed under the Clean Water Act to support the Cataraqui Source Protection Plan, have identified the
majority of the Cataraqui Source Protection Area (CSPA) in Eastern Ontario as having highly vulnerable aquifers (HVAs). The prevalence of HVAs is due to thin or absent soils, fractured bedrock and a relatively high water table. In addition, bedrock
formations in the central and western part of the CSPA are susceptible to the development of karst.
Locally applicable guidance for land use planning authorities to account for aquifer vulnerability and the presence of karst was not available;
therefore, the Cataraqui Region Conservation Authority (CRCA) recently developed a Groundwater Vulnerability Guideline. Its intent is to help proponents of development, consultants, planning approval authorities and the CRCA to: a) identify the
presence, extent and impact on groundwater vulnerability of karst on or adjacent to a property; and b) assess the vulnerability of the bedrock groundwater in a local area (i.e. property parcel or small group of contiguous parcels) based upon
available desktop and field data. Geofirma Engineering Ltd. was retained through an RFP process by CRCA to produce the guideline document. Funding was provided by the Ontario Ministry of Environment and Climate Change.
The guideline is presented
in two parts, an aquifer vulnerability assessment and a karst assessment. Results of the aquifer vulnerability assessment are used to determine whether or not a karst assessment is required. An initial desk-top survey is conducted to see if a
field-based investigation is warranted. A flow chart was established with checklists to ensure proponents obtain all required information to identify groundwater vulnerability. A supporting document was also prepared, with a glossary and karst field
photos, to provide supplementary information about the guideline submissions. The guideline should be read together with the Appendices and Supporting Document. |

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. |
