Demolition and removal of 350 tons of hazardous PCB impacted concrete
Excavation and management of 815 tons of hazardous PCB soil
Management of impacted groundwater
Backfilling of excavation area
Restoration of the site
SES initiated the process by saw-cutting the concrete around the impacted areas, breaking it into manageable pieces using an excavator with a hydraulic breaker. The concrete was stockpiled on-site for loading onto permitted vehicles, which transported it off-site via non-hazardous and hazardous waste manifests to an approved facility.
Subsequent soil sampling occurred beneath the concrete, with one area needing no further excavation and being approved for restoration. In the other area, additional excavation and confirmatory testing were required.
Contaminated soil in this section was removed in two-foot increments, loaded onto trucks, and transported off-site via a hazardous waste manifest for disposal, reaching a final excavation depth of six feet below the concrete.
To manage groundwater in the excavation, a storage tank was used, with the water classified as non-hazardous waste and transported off-site for disposal via a waste manifest.
Clean stone was imported and placed in one-foot layers, compacted with a remote vibratory plate tamper during backfilling. SES completed the project by restoring all sections of the concrete slab removed during the remediation.
