Health Assessment for Lorentz Barrel and Drum Company, San Jose, Santa Clara County, California, Region 9. CERCLIS No. CAD029295706

摘要

The Lorentz Barrel and Drum Company site is on the National Priorities List. The site is a drum-recycling facility that operated from the mid-1940s until July 1987. The on-site environmental contamination consists of polychlorinated biphenyls (4,280 ppm), cadmium (257 ppm), lead (20,600 ppm), DDT (1.9 ppm), and DDE (137.2 ppm) in soil; and barium (160 ppb), benzene (26 ppb), chloroform (29 ppb), 1,2-dichloroethane (58 ppb), 1,1-dichloroethylene (160 ppb), trans-1,2-dichloroethylene (750 ppb), perchloroethylene (140 ppb), trichloroethylene (2,108 ppb), vinyl chloride (1,100 ppb), and polychlorinated biphenyls (6.4 ppb) in groundwater. The site is considered to be of potential public health concern because of the risk to human health caused by the possibility of exposure to hazardous substances via contaminated groundwater permeating private and domestic water supplies.
