Was groundwater considered when selecting the preferred site? Page ContentYes. Source Protection mapping was used to determine which candidate sites were in a Wellhead Protection Area (WHPA), Highly Vulnerable Aquifer (HVA), or had medium to high vulnerability Significant Groundwater Recharge Areas (SGRAs). This important exclusionary criteria was used to remove sites from further evaluation. Of the 502 candidate sites evaluated, 184 were excluded in consideration of groundwater. In Screen 3, groundwater considerations such as depth, flow, and direction were further used to evaluate the short list of sites. The preferred location has favourable groundwater conditions. Placement and design of the facility will consider site-specific groundwater conditions. Home Environmental Resource Recovery Centre
