Public health assessment for TRW Microwave, Inc. (building 825), Sunnyvale, Santa Clara County, California, Region 9. Cerclis No. CAD009159088. Final report

Technical Report · Mon Jan 10 04:00:00 EST 1994

OSTI ID:5176565

The TRW Microwave, Inc. Building 825 site, located in Sunnyvale, Santa Clara County, California, was formally listed on the National Priorities List by the U.S. Environmental Protection Agency in February, 1990. At least one of several underground storage tanks apparently leaked volatile organic compounds (VOCs) into the subsurface soils and groundwater. Various variable organic contaminants (VOCs) have been detected in on-site and off-site groundwater at levels of human health concern. The only completed human exposure pathway is from inhalation by off-site residents of volatile organic compounds migrating into homes from shallow groundwater. The pathway was originally proposed based on extrapolations from groundwater concentrations to soil-gas vapors and from soil-gas vapors to indoor air concentrations using mathematical models. Studies conducted by the California Department of Health Services indicate that the contaminated groundwater may contribute to the indoor air quality but not at a level of public health concern.
