Gagetown Residential Housing Units Remediation Project

The CFHA Gagetown Residential Housing Units (RHUs) were formerly heated using heating oil as a fuel source. Accidental releases of heating oil associated with the former heating oil above ground storage tanks (ASTs) and fuel lines located in the basement sub slabs of the residential housing units (RHUs) resulted in contamination at various CFHA Gagetown RHUs. The proposed project consists of remedial excavation of the petroleum hydrocarbon (PHC) impacted sub slab soils and/or groundwater in the basements of the RHUs and of site disposal of the soils and/or groundwater at a licensed disposal facility. The remedial excavation work is generally contained within the basements of the RHUs (interior excavation of the impacted soils) and within the footprint of the building. In some cases where the PHC contamination migrated towards the RHUs foundation draining system, the remediation potentially can extend outside of RHUs and is limited to the area in immediate vicinity of the foundation walls. Following the completion of the successful remedial excavation, the excavation is backfilled with clean material and the sub slab in the RHUs basements and/or outside areas are reinstated.
