This Superfund project was the third phase of a demolition/remedial project at the site located in a residential area. OP-TECH preformed the excavation, removal and disposal of a variety of types of impacted soils. The unique challenges associated with this site included coordination with the contractors performing the Phase 2 demolition as well as the next phase of subsurface removals and the characterization of waste streams as the work progressed.


The work was performed during the frigid winter months, which made the maintenance and operation of the water treatment system as well as the daily monitoring of site dust emissions challenging. The work included construction of a decontamination pad as well as an carbon based ground water treatment system that utilized heaters and circulating pumps that prevented the system from freezing. OP-TECH also established work zones and performed continuous upwind and downwind air monitoring of all work areas. In total OP-TECH removed and disposed of 21,000 tons of non hazardous soil, 760 tons of TSCA soil, 4,500 tons of benzene contaminated soil, 100 tons of non hazardous concrete and 10,000 tons of asbestos contaminated soil. Following the excavation, OP-TECH backfilled and compacted all excavation areas with clean imported material. . Decontamination stations were built at the asbestos contaminated areas and maintained throughout the project. Topsoil was stockpiled for application under the next phase of the project.


During the project, a state, federal and local operation called "Vigilant Guard" was performed on a section of the property which included the deployment of over 5000 military personnel and the simulation of a 5.7 earthquake drill.
