Superfund Record of Decision (EPA Region 9): Applied Materials, Inc., SuperfundSite, Santa Clara, CA. (First Remedial Action), September 1990

摘要

The 9-acre Applied Materials site is an active equipment manufacturing facilityin Santa Clara, Santa Clara County, California. The site is located within the San Tomas Aquino floodplain, and land use in the area is primarily light industrial, commercial, and residential. Shallow ground water at the site is a potential drinking water source. In 1984 and 1985, as part of interim onsite cleanup activities, Applied Materials excavated and removed underground tanks, piping, and more than 60 cubic yards of contaminated onsite soil, and installed an air stripping unit onsite to treat VOC-contaminated ground water. The Record of Decision (ROD) provides a final remedy for contaminated onsite ground water at the Building 1 area. The primary contaminants of concern affecting the ground water are VOCs including PCE, TCE, and 1,1,1-TCA.
