Superfund Record of Decision (EPA Region 9): Intersil/Siemens Superfund site, Cupertino, CA. (First remedial action), September 1990. Final report
Technical Report
·
OSTI ID:5144853
The 12-acre Intersil site contains two industrial properties, Intersil, Inc., and Siemens Components, Inc., in Cupertino, California. Since 1978, Siemens has manufactured semiconductor products for optoelectronic applications at the site. Solvents are currently stored above-ground and wastewater is treated in an acid neutralization system. From 1967 to 1988, Intersil operated as a semiconductor assembly facility. Two vaulted and one unvaulted underground acid neutralization systems, now excavated, were used in the operation. Both facilities used various organic solvents and commercial mixtures. Contamination, a result of releases from the underground waste handling facilities at both plants, has been detected in soil and ground water beneath the site. A contaminant plume also has been detected, which affects offsite ground water. The Record of Decision (ROD) outlines the final remedy addressing onsite source areas, and onsite and offsite contaminated ground water. The primary contaminants of concern affecting the soil and ground water are VOCs including PCE, TCE, and toluene; and other organics including phenols.
