Request a statistical justification for the sufficiency of six boreholes to characterize the geochemical homogeneity of the entire repository volume, specifically regarding the 5% subordinate rock types (amphibolite and dykes).
Strategic Rationale
"The Proponent's submission relies on a limited dataset (six boreholes) to claim the rock is chemically stable. However, the text acknowledges 5% of the core is 'subordinate rock types' like amphibolite. If these minority rock types contain localized sulphides and are excavated to surface storage, they could generate Acid Rock Drainage (ARD). Melgund Township relies on local groundwater and surface water; the community requires evidence that these 'minor' rock types have been adequately sampled to rule out leaching risks that could contaminate the local watershed."

Understanding the Impacts of Nuclear Waste on our Community
This digital archive houses the public comments submitted to the Impact Assessment Agency of Canada regarding Project 88774: The Nuclear Waste Management Organization Deep Geological Repository (DGR) for Canada's Used Nuclear Fuel Project. The impact assessment is led jointly by the Impact Assessment Agency of Canada and the Canadian Nuclear Safety Commission. This archive preserves community perspectives, concerns, and observations shared during the assessment process, particularly in relation to Melgund Township, Northwestern Ontario and the communities of Dyment and Borups Corners who are the closest and most impacted of all in the process.
