摘要

The Commencement Bay, South Tacoma Field site occupies 260 acres of land locatedin the southwestern section of the city of Tacoma in Pierce County, Washington. The South Tacoma Field site poses a public health hazard to trespassers who repeatedly ingest contaminated surface soils, surface water, and sediment during recreational activities at the site. Exposure to the contaminants arsenic, copper, lead, manganese, as well as polychlorinated biphenyl and polycyclic aromatic hydrocarbon compounds may have occurred in the past, may be presently occurring, and may occur in the future, which could result in noncarcinogenic and carcinogenic health effects. Potentially, the site can pose a public health hazard through exposure to groundwater and subsurface soil contaminants that could cause adverse health effects. Additionally, should contruction/excavation uncover contaminated subsurface soils, workers as well as recreationalists/trespassers may be exposed.
