EPA Superfund Site Link 2900 SEMICONDUCTOR DRIVE SANTA CLARA, CA 95052

EPA Superfund Site : “The National Semiconductor Corporation (National Semiconductor) previously manufactured electronic equipment at this 50-acre site. Underground storage tanks, sumps, and pipes are the suspected sources for contaminated groundwater and soil in Sunnyvale underneath the site. Beginning in 1982, National Semiconductor closed and removed its leaking tanks and equipment, 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, including trichloloethene (TCE), which, along with other nearby National Priority List (NPL) sites including the Monolithic Memories Superfund Site, 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.”

State of California Geotracker Site: “National Semiconductor Corporation (NSC) is located at 2900 Semiconductor Drive, Santa Clara. The NSC site is bordered by Central Expressway to the north, Kifer Road to the south, Lawrence Expressway to the east, and industrial/commercial buildings to the west. The site encompasses approximately 60 acres. Continue reading “TEXAS INSTRUMENTS – FORMER NATIONAL SEMI CONDUCTOR (SL720841216) EPA Superfund Site Santa Clara California”

Groundwater Contamination Map, Toxic Plumes Map Source: The Chemical Legacy of Old Silicon Valley, NBC Bay Area, Map Editor Scott Pham 2019 The red dots represent Daycare centers from 2019. NBC Bay Area had a series of maps that indicated where the toxic waste sites were located and the extent of the damage encompassing vast areas of the community but they took it down. The pollution is in the groundwater so it covers a vast area in Pink.

Envirostor State of California Link: “The EPA added this site to the National Priorities List (NPL) in 1991. This Superfund site is comprised of several former Fairchild Semiconductor Corp facilities spanning 56 acres in Mountain View. The Fairchild Semiconductor Corp – Mountain View site is one of three Superfund or NPL sites that are being cleaned up simultaneously. The other two Superfund sites are the Intel – Mountain View site and the Raytheon site. All three sites are located in the Middlefield-Ellis-Whisman (MEW) Study Area and are being addressed collectively as the MEW SIte. Site investigations at several of these facilities during 1981 and 1982 revealed extensive soil and groundwater contamination, primarily VOCs. Soil cleanup by soil vapor extraction, excavation, and aeration has been completed at all the MEW study area sites. Groundwater remediation is ongoing at the MEW Study Area.”

The contaminants which have been detected in soil and groundwater include trichloroethylene (TCE), trichloroethane (TCA), dichloroethylene (DCE) and chloroform.

EPA Superfund Site: INTERSIL INC./SIEMENS COMPONENTS CUPERTINO, CA

Apple Computer, Kaiser Permanente Child/ado Psy and Kaiser Permanente – CDRP (Chemical dependency recovery program) are located on the EPA Superfund Tri-Site where there are toxic chemicals in the ground that emerge as toxic vapor and the deed restrictions are present to stop organizations from having hospital facilities on the site. Strange thing is Kaiser Permanente operates two facilities on the site. So I would imagine that each patient must be signing a waver when they visit the facility?

I know Apple does not have daycare at their facility they would not be stupid enough to do such a thing. I find it strange that people are willing to work on a toxic waste site. But I guess they know what they are doing. Surely Apple would inform everyone who has access to the site, including delivery drivers as they are required by the deed restrictions?
