1 APPENDIX TSD#-B COMPARATIVE EVALUATION OF ALTERNATIVE SITES GEOLOGY, HYDROGEOLOGY & GEOTECHNICAL COMPONENT Environmental Component Summary of Site Considerations Interpreted direction of vertical groundwater flow on-site and in Site-vicinity (i.e., area of groundwater recharge, transitional flow, or groundwater discharge): Based on the groundwater elevation data collected to date, vertical gradients at the Site are indicated to be typically weakly downward, or absent. The BR Site is not part of a regional groundwater recharge system to the basal glacial till and bedrock. The shallow overburden used locally for dug wells is recharged locally by precipitation; therefore development of the BR Site will not affect off-site groundwater availability. 3. SITE COMPARISON GEOLOGY, HYDROGEOLOGY & GEOTECHNICAL 3. Comparison of Sites For the purpose of selecting the preferred Site based on the geology, hydrogeology and geotechnical disciplines, the assessment criteria is Which Site is preferred for protection of groundwater? The associated indicators considered are geological setting; type and thickness of natural on-site attenuation layer; presence and quality of groundwater resources on-site and in Site-vicinity; and, interpreted direction of vertical groundwater flow on-site and in Site-vicinity (i.e., area of groundwater recharge, transitional flow, or groundwater discharge). The technical factors considered in applying these indicators are associated with the geological and hydrogeological setting; the geotechnical characteristics are related to design of the facilities on the preferred Site. The BR Site is not part of a regional groundwater recharge system to the basal glacial till and bedrock. The shallow overburden used locally off-site for dug wells is recharged locally by precipitation; therefore development of the BR Site is not expected to affect off-site groundwater availability. The NRR Site is interpreted to be located within a large regional groundwater recharge area; however, in view of the relatively small portion of the recharge ridge area occupied by the Undertaking and the relatively low overall water demand, it is not expected there would be noticeable effects on off-site groundwater availability. The BR Site and its associated thick natural low permeability silty clay attenuation layer offers more favourable natural containment properties (i.e., natural backup to an engineered system, etc.) compared to the NRR Site in the unlikely event of an unmitigated release of leachate from the engineered containment components of the waste management facility. Based on the assessment criteria for the geology, hydrogeology and geotechnical disciplines and the associated indicators, the preferred site from the perspective of the protection of groundwater is clearly the BR Site. 3. Results of Site Comparison The preferred site based on the geology, hydrogeology and geotechnical disciplines is the BR Site. February 3 - DRAFT 53
