"Intersil, Inc. and Siemens Components have manufactured semiconductors for several years on two locations covering 15 acres. Siemens currently is an operating facility, while Intersil is now inactive. Investigations conducted in 1982 as part of the California Regional Water Quality Control Board's (CRWQCB) underground storage tank leak detection program found volatile organic compound (VOC) contaminated soils on- and off-site. This contamination is believed to have resulted from localized spills and from leaking underground storage tanks and piping from the two companies. At the Siemens facility, four underground tanks were used to store waste solvents. At the Intersil facility, possible sources of contamination include the waste neutralization systems and the concrete scrubber pit sumps. More than 300,000 people obtain drinking water from public wells located within 3 miles of the site. The groundwater is used for the municipal water supplies of the cities of Cupertino, Santa Clara, and Sunnyvale. Five municipal water supply wells are located within 1 mile of the site. Three of these wells, operated by the City of Santa Clara, are located hydraulically downgradient from the site. The distance from the site to the City of Santa Clara Well #15, the closest municipal well, is 1,300 feet. Calabazas Creek, an intermittent stream, is located approximately 1,500 feet east of the site." (
