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.

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.

I live next to Google – and on top of a toxic site. Don’t let polluters be evil

By Jane Horton, the Guardian Wed 19 Mar 2014 15.45 GMT https://www.theguardian.com/commentisfree/2014/mar/19/google-mountain-view-toxic-waste
“I live across the street from one of Google’s many Mountain View campuses in California. My beloved home – a little farmhouse I bought and moved into with my family in 1975 – now lies above the Middlefield-Ellis-Whisman Superfund Study Area (or MEW Superfund site), an area polluted by 11 Potentially Responsible Parties, well-known, multi-billion-dollar Silicon Valley companies that are possibly to blame “for generating, transporting or disposing of the hazardous waste found at the site”.”

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.

by Mark Noack/ Mountain View Voice

“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. “

What politicians, the Navy and the EPA don’t want you to know: Treasure Island and Hunters Point are equally toxic Superfund sites

“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.

Pelosi and the Treasure Island Land Grab By Michelle Malkin

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.”

Navy does damage control for Pelosi, Feinstein and Lennar as it continues to claim Treasure Island and Hunters Point Shipyard are ‘safe’

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.”
