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.”
Apple In Sunnyvale and there are four schools and two daycares on this site which are against the rules for TCE exposure protocol which is to not have any children under the age of 21 to be exposed to these chemicals, no daycare, no adult care. This site has housing on it.
The TRW Microwave, Inc. (Building 825) site is one of three sites contributing contamination to a groundwater plume in Sunnyvale, California. Former microwave manufacturing and semiconductor processing activities contaminated groundwater and soil with volatile organic compounds (VOCs).
The former TRW Microwave Superfund Site (TRW Site), part of the “Triple Site” in Sunnyvale, California, is located at 825 Stewart Drive and neighbors multiple other sites, including: the Advanced Micro Devices (AMD) Buildings 901/902 Thompson Place Superfund Site (AMD 901/902 Site), the AMD 915 De Guigne Drive Superfund Site (AMD 915 Site), the Philips Semiconductors Site (Philips Site; formerly Signetics Inc.), which includes the properties at 811 Arques Avenue, 440 North Wolfe Road, and facilities along Stewart Drive, and the Mohawk Laboratories Site. A groundwater plume composed of volatile organic compounds (VOCs), including trichloroethene (TCE), extends from these sites more than a mile north in Sunnyvale to beyond Highway 101.
The TRW Site, together with three other operable units (OUs), was covered by a 1991 Record of Decision for the Triple Site, all located in Sunnyvale. The four OUs for the Triple Site are as follows:
(1) The AMD 901/902 Site OU; (2) The Philips Site OU; (3) The TRW Site OU; and (4) The Companies Offsite Operable Unit (OOU), a commingled plume of contaminants which originated from the other three operable units (and has contributions from other sites in the area).
At the time of adoption of the 1991 Record of Decision, the OOU was defined as a 100-acre area, downgradient and north of the Triple Site in an area bounded by the Sunnyvale East Drainage Channel on the west and Santa Paula Ave. on the east, and as the area inside a 5 micrograms per liter (µg/L) contour for trichloroethene (TCE) in groundwater. Over 400 residences and at least 4 schools are present within the OOU.
The TRW Site was occupied by Aertech Industries from 1968 until it was sold to TRW Inc (TRW) in 1974. In 1987, TRW sold the facility to FEI Microwave, Inc. In 1993, FEI Microwave stopped production and in 1995 the site was acquired by Stewart Associates and leased to research and development companies until 2001. The exterior of the building was remodeled between 2001 and 2003, including demolition of part of the existing structure and construction of a new two-story building. In December 2002, TRW merged with Northrop Grumman. In 2004, the property was purchased by Pacific Landmark, and then by Hines in 2014 and then GI Partners, the current owner, in 2016. During these changes in site ownership, TRW and then Northrop Grumman retained responsibility for site cleanup.
The primary activity at the TRW Site was assembling and testing microwave components until semiconductor processing began in 1970. Primarily solvents and small quantities of acids were used in the assembly areas for semiconductors. Solvents, acids, and heavy metals were used in the fabrication areas and plating shop. The paint shop used paints and solvents.
Acid rinse water generated by the assembly processes was neutralized on-site and discharged to the City of Sunnyvale sewer system. An underground ammonia gas acid neutralization system was installed when the facility first opened. Floor drains and acid sinks in the plating shop were connected to buried plumbing that carried acid waste to the neutralization system. This system was closed in 1986, and the underground piping was sealed. The system was replaced with three aboveground tanks. Spent solvents were stored in one of four on-site underground tanks. After 1982, solvents were stored in drums and transported off-site.

The Teledyne property is part of a two-property Superfund site along with the adjacent Spectra-Physics property.
The responsible parties (RPs) for the Teledyne/Spectra-Physics site completed a Monitored Natural Attenuation (MNA) study in the off-property area north of and downgradient of the site. The MNA study concluded that natural breakdown of the chlorinated volatile organic compounds of concern is occuring naturally and at the same rate as groundwater extraction. As a result, only a few of the off-property downgradient extraction wells were operating mainly to maintain hydraulic control of the plume. The RPs completed a pilot study to test the feasibility of enhanced reductive dechlorination (ERD) and concluded that ERD is feasible with bioaugmentation of the Shallow Zone.
Within the last five years, the RPs detected elevated source areas at the Teledyne property using high resolution technology and continuously logged and screened ERD injection well boreholes. Implementing a full-scale ERD treatability study, they have been and are currently remediating the property with groundwater-CVOC levels dropping from as much as over 80,000 ug/l to low multiples of MCLs. Several rounds of ERD injections successfully cleaned up most of the Shallow Zone at the Teledyne property and the adjacent Spring Street residential area to drinking water standards and the treatability study was even more successful in the underlying Upper and Lower Intermediate Zones.
An on-property IA VI evaluation at a SpectraPhysics property in 2004 indicated no IA-CVOC contamination above the Regional Water Board’s 2008 ESLs. More recently, the RPs also assertively evaluated potential IA VI in the off-property commercial North Bayshore and residential Spring Street areas to conclude that IA VI is not occurring in most of the commercial area and is occasionally occurring in several homes in the residential area. The RPs installed sub-slab depressurization systems in the impacted on-property commercial buildings and offered the affected residents crawl space fans to address the issue.
Nine indicator chemicals were identified from approximately 30 chemicals detected in the Study Area. The nine indicator chemicals are as follows: 1,1-dichloroethane (1,1-DCA) 1.1-dichloroethylene (1,1-DCE) 1.2-dichloroethylene (1,2-DCE) tetrachloroethylene (PCE) toluene 1,2,4-trichlorobenzene (1,2,4-TCB) 1,1,1-trichloroethane (1,1,1-TCA) trichloroethylene (TCE) vinyl chloride (VC

Silicon Valley was all abuzz on Friday over news that two of Google‘s buildings on North Whisman Road in Mountain View were suffering from toxic vapors seeping up from the ground below.
Article explains how a farmer living across the street from Google, where they built stations to remove contaminated groundwater out of the ground and clean it by building silos that mixed the polluted water to air so the vapor could be removed from the water and spread into the neighborhoods.
“An approved project to build 26 homes at 277 Fairchild Drive is being delayed by officials with the U.S. Environmental Protection Agency after they discovered the site’s soil exceeded safety levels for trichloroethylene (TCE).
Representatives for the developer, Warmington Fairchild Associates LLC, say they will clean up the soil contamination over the coming months before proceeding with construction.”
” In a settlement reached with the EPA earlier this summer, Warmington officials agreed to clean up the hazardous vapors in the top layers of soil. In addition, they will inject “bioremediation” chemicals into the aquifers below, which will help break down the TCE contaminating the groundwater. “
October 31, 2018 by Carol Harvey San Francisco Bay View; National Black Newspaper Comprehensive Article Watch the Videos, the political corruption is explained. EPA director on the TIDA development board.
“Though Treasure Island bears a certified EPA Superfund site identification number, CA7170023330, EPA officials like Jared Blumenfeld, TIDA board member who rose to direct federal EPA District 9, refuse to include this Bay Area toxic landform on the EPA’s National Priorities List (NPL) of Superfund sites online, thereby concealing the truth from potential Treasure Island renters.”
There is a picture of Paul Pelosi, Nancy Pelosi’s son and Jared Blumenfeld “Paul Pelosi Jr. poses with Jared Blumenfeld, federal director for EPA San Francisco District 9, when Blumenfeld was on the Treasure Island Development Authority Board.”
Jared Blumenfeld was the EPA Administrator for the Western District of the US in the Obama Administration. Jared Blumenfeld was appointed to the California EPA agency by Governor Gavin Newsom in January 2019.
Article explains the political connections to the developers of Treasure Island. To Nancy Pelosi’s family members directly involved in taking the island from the Navy and putting it in the hands of developers that just happen to be related or worked for all of the politicians in Nancy Pelosi’s tender care. They then put homeless people into the barracks of the island which is a superfund clean-up for nuclear radiation.
“Treasure Island is not a case of a small town that has relied on a local military base for its livelihood for decades. It is a land grab by politicians for well-connected developers. Tony Hall, the former executive director of the Treasure Island Development Authority, told us the city’s effort to develop the island is a “den of corruption.” Treasure Island Community Development, the prospective developer for Treasure Island, was granted a no-bid contract by the city.”
Another $22 million down the rat hole? by Steve Zeltzer, KPFA WorkWeek Radio July 5, 2018
“The U.S. Navy had its every-three-months dog and pony show at the Treasure Island Restoration Advisory Board (RAB) meeting on Tuesday, June 19, 2018. The previous meeting included a Tetra Tech representative and a loud confrontation, but this time Tetra Tech representatives were not on the panel since there are now two Tetra Tech managers in federal prison for falsifying the cleanup records at Hunters Point and an ongoing grand jury investigation with likely more sealed indictments that could lead to further criminal action against the top management of Tetra Tech.
Since the scandal blow-up, however, Congresswoman Pelosi has arranged to get another $42 million from the budget reconciliation bill for more retesting on formerly tested contaminated land in the Superfund site at Hunters Point Shipyard. This is after $1 billion has already been expended by the U.S. government to clean up Hunters Point Shipyard and Treasure Island, which are both Superfund sites.”
“Behind the continued effort to push forward with both the developments at Hunters Point Shipyard and Treasure Island are Congresswoman Nancy Pelosi and Sen. Dianne Feinstein, who have deep financial connections to this development of the Shipyard and Treasure Island. Feinstein’s husband, Richard Blum, financially pushed for the development; his company has the primary contract to build condos at Treasure Island. Congresswoman Nancy Pelosi’s nephew, Laurence Pelosi, was an executive of Lennar – in charge of real estate acquisitions – while she was pushing for the development and getting hundreds of millions for the “cleanup.””
“Former Mayor Willie Brown had been instrumental in arranging for the U.S. Navy to prepare the site to turn it over to the city for future million-dollar condos. In the meantime, they placed low income African American families and homeless on the Island.”
