Superfund Record of Decision (EPA Region 9): TRW Microwave, (Advanced Micro Devices 901), (Signetics), Sunnyvale, CA. (First remedial action), September 1991. Final report

Technical Report ·
OSTI ID:7250974
The 1-acre TRW Microwave site is an active semiconductor manufacturing facility in Sunnyvale, Santa Clara County, California. The site is part of a larger study area that includes four Operable Units (OUs): the 3-acre Advanced Micro Devices (AMD) 901/902 site, the Signetics site, the 1-acre TRW Microwave site, and a 100-acre offsite contaminated ground water plume. Currently, the contaminated ground water is not used as a drinking water supply, but the State considers several of the aquifers to be potential drinking water sources. As a result of responses to an information questionnaire regarding an underground tanks investigation at the TRW site, a number of investigations were conducted that revealed extensive contamination of onsite soil and ground water. The Record of Decision (ROD) collectively addresses final remediation of soil and ground water in the four separate OUs within the study area. The primary contaminants of concern affecting the soil and ground water are VOCs including PCE and TCE; and other organics. The selected remedial action for the site is included.
