PFAS Remediation Project at AEC 11, CFB Comox

The Department of National Defence (DND) is proposing a project. This Project is planned to begin in the spring of 2027 and will be completed by a civilian contractor on behalf of DND. Area of Environmental Concern (AEC) 11 is contaminated with Per-and polyfluoroalkyl substances (PFAS) due to historical use of aqueous film-forming foams (AFFF). The Project involves excavating PFAS impacted soil, and either disposing of that soil at an approved provincially licensed landfill or amending it with a PFAS adsorbent product and returning the amended soil to the excavation area. The Project may also install a permeable reactive barrier to passively treat groundwater. This remediation is intended to remove or immobilize PFAS, improve surface water and shallow groundwater conditions, and reduce off site migration. Post-construction monitoring will be conducted to assess performance of remediation activities.
