“Tyco, previously known as Raychem, is an electronics manufacturer. Raychem had a hazardous waste facility permit and closed its hazardous waste management units at this site. DTSC has been overseeing corrective action at Tyco under a corrective action consent agreement. The main contaminant is PCBs. Soil removal was completed to industrial levels. A land use covenant has been entered into and filed with County. Tyco is currently conducting long term groundwater monitoring.”

POTENTIAL CONTAMINANTS OF CONCERN
As a result of historical operations at the Property, certain hazardous
materials, including volatile organic compounds, semi-volatile organic compounds, PCBs, dioxins and dibenzofurans were released into the soil and groundwater at the Property.
TEXAS INSTRUMENTS – FORMER NATIONAL SEMI CONDUCTOR (SL720841216) EPA Superfund Site Santa Clara California
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”
The Chemical Legacy of Old Silicon Valley showing the Toxic Plumes, areas of groundwater contamination in Silicon Valley
NBC Bay Area Video on the Toxic waste sites all over Silicon Valley. They had an interactive map but they took it down from their website.
Original article: NBC map showing the hundreds of sites on a map so you can see if you are affected by the pollution of Silicon Valley. https://www.nbcbayarea.com/brchannel/Map-The-Chemical-Legacy-of-Silicon-Valley-258950021.html From this map you can see that Apple and Google Headquarters are located on 2 superfund sites each where the polution is TCE Trichloroethylene where there are restrictions that require no person under the age of 21 can occupy any building built on the properties.
There is Kaiser Permanente building for Children and Adult psychiatric care built right on top of the street address of three sites and two of them are under Apple which is across the street. Note the tabs to show the daycare facilities that are on the purple areas that are mapped out to show the pollution.
The Map Article was taken down by NBC Bay Area.
