Health assessment for National Semiconductor Corporation, Santa Clara, Santa Clara County, California, Region 9. CERCLIS No. CAD041472986. Preliminary report

Technical Report ·
OSTI ID:5122785

The National Semiconductor Corporation site is on the National Priorities List. Underground-storage tanks, sumps, and pipes are suspected to be the source of contaminated ground water and subsurface soil. The environmental contamination on-site consists of tetrachloroethylene 1,1,1-trichloroethane, trichlorobenzene, benzene, methanol, and ethylbenzene and xylenes in subsurface soil; and trichloroethylene, 1,1,1-trichloroethane, xylene and acetone in groundwater. The environmental contamination off-site consists of 1,2-dichloroethylene 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 migration of contaminants from on-site subsurface soil and ground water to off-site public-water-supply wells.
