Location: Tacoma, Washington
Client: Washington State Department of Ecology
Contract Value: $940,000
AEC has been awarded multiple phases of work for the Asarco Smelter Plume Cleanup program in and around Tacoma, WA. This program, led by the Washington State Department of Ecology, is an effort to remediate arsenic and lead impacted soils from residential properties lying in the plume of the Former Asarco Smelter. To date we have been awarded three phases and have remediated and restored 57 individual residential yards in Tacoma and on Vashon-Maury Island.
For the EPA 2015 Group 1B Property project, using AEC-owned and operated and some rented equipment, we performed the surgical excavation of twenty-two (22) residential properties, removing arsenic and lead contaminated soils. We also implemented temporary construction controls for environmental protections.
AEC hauled and disposed of contaminated soils at the nearby LRI Subtitle D landfill. Once the contaminated materials had been removed, our crews used imported clean soil to backfill and grade the yard and restored each property to preconstruction conditions or better with various landscaping, lawn restoration and maintenance activities.
