2900 SEMICONDUCTOR AVE
The National Semiconductor Corporation (National Semiconductor) manufactures electronic equipment at this 50-acre site. Underground storage tanks, sumps, and pipes are the suspected sources for contaminated groundwater and soil. Since 1982, National Semiconductor has closed its leaking tanks, instituted a groundwater pump and treat system, and removed contaminated soil from selected areas of the facility. The contaminants of concern are primarily chlorinated organic solvents, which, along with other nearby National Priority List (NPL) sites, have contaminated a common groundwater area. Although these nearby sites are listed separately on the NPL, the cleanup activities at some of the sites are being coordinated as part of an area-wide cleanup approach. Approximately 300,000 people live within 3 miles of the site and depend on groundwater as a source of drinking water.
