Health assessment for Fairchild Semiconductor Corporation Proposed National Priorities List Site, Intel Corporation National Priorities List Site, Raytheon Company National Priorities List Site, Mountain View, California, Region 9. CERCLIS No. CAD095989778. Final report

Technical Report · Tue Feb 07 00:00:00 EST 1989

OSTI ID:5150779

The Fairchild Semiconductor Corporation, the Intel Corporation, and the Raytheon Company each have a facility located approximately 3 miles south of San Francisco Bay in Mountain View, California. The Intel and Raytheon facilities are on the National Priorities List (NPL) while the Fairchild facility is a proposed NPL site. Within the one-half square mile area containing the three sites, 37 potential and two inferred sources of contamination have been identified. The major contaminants for the three sites include trichloroethene, 1,1,1-trichloroethane, 1,1-dichloroethene, 1,2-dichloroethene, 1,1-dichloroethane, chloroform, tetrachloroethene, 1,2-dichlorobenzene, trichlorotrifluoroethane (Freon 113), and vinyl chloride. These contaminants are attributed to the sites and have been found primarily in the ground water and subsurface soil on the sites and in ground water off the sites. Contaminant concentrations in surface soils were within the normal range of background values. Volatile organic compounds (VOCs) have been found in surface water west of the study area in Stevens Creek, an intermittent stream. The source of these contaminants is suspected to be treated ground water that has been pumped from the Fairchild and Raytheon sites and discharged to Stevens Creek under a permit.
