SITE BACKGROUND

The Applied Materials site is located in a light industrial and commercial area in Santa Clara, California. A large industrial building occupies most of the site. The facility has manufactured equipment for the fabrication of semiconductor wafers from 1974 to the present. During the 1970s, volatile organic compounds (VOCs) were used as industrial solvents for cleaning and degreasing. Acids, caustics and other chemicals were also in use at the facility. Facility operations led to groundwater contamination. After construction of the site’s remedy, operation and maintenance activities and monitoring are ongoing.
