Health Assessment for South Cavalcade National Priorities List (NPL) Site, Houston, Harris County, Texas, Region 6. CERCLIS No. TXD980810386

摘要

The South Cavalcade National Priorites List site is located in north Houston, Harris County, Texas. The site is about 66 acres and is located in an industrial area, where presently several trucking firms are operating on-site. Residential and small commercial operations are located to the west of the site. Elevated levels of polycyclic aromatic hydrocarbons (PAHs), volatile organic compounds (VOCs), other organic compounds, and several heavy metals have been found in either the ground water, soils, surface waters, or sediments. The site is of potential public health concern because of the risk that exposure to high levels of PAHs in on-site soil and sediment and PAHs, metals, and volatiles in off-site ground water may occur or may be occurring via oral and dermal exposure. Inhalation of PAH-contaminated fugitive dusts is of concern with respect to on-site worker activities. Although long-term exposure to contaminants in on-site media is currently not probable, if the site is used in the future for residential or commercial purposes, the present level of contamination would be of concern in regard to potential long-term adverse health effects.
