The Mora Drive Site was formerly commercial/industrial. It includes several former DTSC sites: PLESSEY #2 (43360131), PLESSEY #3 (43360135), and SYMTRON CORP. (43360124) all of which were determined to require no further action. Lennar conducted sampling in 2015, 2016 and 2017 to confirm that the site has elevated levels of tetrachloroethylene and trichloroethylene in soil gas. Lennar plans to develop the property into residential.
Raychem Corporation (Raychem) operated a facility which manufactured high technology plastic and electrical insulation products and also engaged in management of hazardous waste pursuant to a hazardous waste facility permit (Permit). The Permit, issued in 1983 by the California Department of Health Services, the predecessor of DTSC, allowed operation of a wastewater treatment system, a hazardous waste storage yard and a potassium ferrocyanide tank farm. On January 9, 1997, DTSC approved the closure activities of aboveground portions of these hazardous waste management units.

1.2. Raychem Corporation, the Covenantor’s predecessor, manufactured hightechnology plastic and electrical insulation products. It also engaged in management of hazardous waste pursuant to a hazardous waste facility permit issued by the California Department of Health Services, the predecessor agency of the Department. The hazardous waste facility permit allowed Raychem Corporation to operate a wastewater treatment system, a hazardous waste storage yard and a potassium ferrocyanide tank farm. On January 9, 1997, the Department approved the closure activities of the aboveground portions of these hazardous waste management units. Raychem Corporation proceeded with corrective action under the Department’s oversight to address the release of hazardous waste in soil and groundwater. Raychem merged with the Covenantor in 1999. The Covenantor has conducted corrective action at the Property under the Department’s oversight, including removal of contaminated soil, installation of an engineered multi-media cap over an area of subsurface contamination and 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.
“The Site covers approximately 0.9 acre and was used for an orchard and flower growing business. Sequoia Union High School District (SUHSD) purchased the Site and planned for construction of a school facility for a charter school. The construction consisted of classrooms, a gymnasium and paved parking areas. The school campus is an expansion of the adjacent campus at 1010, 1020, 1040 and 1056 Myrtle Street (Site Code 204238) that was cleaned up under DTSC’s oversight in early 2011. In September 2013, SUHSD entered into a voluntary cleanup agreement with DTSC for cleanup of the soil contamination. The Site was cleaned up by soil excavation, capping and offsite disposal. Soil contaminated with arsenic, lead, dieldrin and DDT was excavated from classroom building locations and consolidated in a 0.5-acre area onsite that will be used for parking and gymnasium. Approximately 305 cubic yards of excess contaminated soil that cannot be used onsite was disposed of to a permitted landfill. The Site cleanup and school construction was completed in September 2014.” Continue reading “East Palo Alto – MYRTLE STREET HIGH SCHOOL CAMPUS PHASE 2 (60001925)”→
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.”

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.”
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?
Given the Covid Epidemic it is clear that constant exposure to TCE contamination damages the immune system and may have caused the employees at Apple to be further susceptible to Covid infections. –
“The Intersil/Siemens Superfund Site includes the following three areas: 1) the former Intersil facility, located at 10900 North Tantau Avenue, Cupertino; 2) the former Siemens facility, located at 10950 North Tantau Avenue, Cupertino; and 3) the Off-Site Study Area, located north of and hydraulically downgradient from the two former facilities in Sunnyvale. Investigations conducted in the 1980s as part of the California Regional Water Quality Control Board’s (Regional Board’s) underground storage tank (UST) leak detection program found volatile organic compounds (VOCs) in soil on- and off-site. The primary contaminant of concern at the site is the VOC, trichloroethene (TCE).
• Former Intersil Facility – Intersil, Inc. operated at the property from 1968 to 1988 and initiated investigations in 1983. The potential sources of contamination were removed between 1986 and 1988, including waste neutralization systems, a waste solvent tank, and an above-ground chemical and hazardous waste storage area.
• Former Siemens Facility – Litronix and its successor, Siemens Microelectronics, Inc., operated at the property from 1970 to the mid-1990s. Until 1982, liquid wastes were stored in five USTs that were removed in 1982. From 1982 until cessation of operations, liquid wastes previously stored in USTs were temporarily placed in the hazardous materials storage area for off-site disposal or recycling. Investigations began in 1982 after the discovery of contaminants during the removal of the USTs.
Drinking water for Sunnyvale and Cupertino is not affected by this contamination. Calabazas Creek, an intermittent stream, is located approximately 1,500 feet east of the site. “
