Description and History

NPL Listing History

NPL Status: Final

Proposed Date: 10/15/84

Final Date: 06/10/86

Deleted Date:

The Intel Magnetics site is a 1-acre facility that produced and tested magnetic products and computer memories. Micro Storage occupied the site from 1985 to 1986 and used the facility for research and development and pilot manufacturing. Micro Storage also occupied a property adjacent to and upgradient from the site that contributes to the contamination. Monitoring wells on the site are contaminated with volatile organic compounds (VOCs), believed to have resulted from surface spills and a leak from an underground storage tank. This is one of 28 NPL sites in the South Bay Area of San Francisco. Facilities at these sites have used a variety of toxic chemicals, primarily chlorinated organic solvents, which have contaminated a common groundwater basin. Approximately 300,000 people depend on groundwater within 3 miles of the site as a source of drinking water. Twenty Santa Clara wells and four Sunnyvale wells are located within a 3-mile radius of the site.

Investigation and Cleanup Activities

Initial Actions

Immediate Actions: The company installed a groundwater extraction and treatment system to pump and treat contaminated groundwater in 1990. In early 1991, additional wells for the extraction and treatment system were installed at the site.

Cleanup Ongoing

Entire Site: The potentially responsible parties, under State supervision, completed an investigation into the nature and extent of contamination at the site in early 1991. A groundwater extraction and carbon adsorption treatment remedy was chosen in late 1991. Construction of the treatment system began in late 1991 and was completed in 1992. California's Regional Water Quality Control Board and the EPA are currently investigating the potential need for upgradient remediation. Groundwater monitoring will continue until cleanup goals are met.

Cleanup Results to Date

The construction of cleanup remedies is complete. The pumping and treating of contaminated groundwater has reduced contaminant concentrations, minimizing the potential of exposure to contaminated groundwater at the Intel Magnetics site. Monitoring will continue until established cleanup goals are met.

The Addendum to the Fourth Five-Year Review Report signed on May 1, 2013, determined that the remedy is protective. This document may be accessed in the Technical Documents subsection of the Documents and Reports section below.
