Description and History

NPL Listing History

NPL Status: Final

Proposed Date: 10/15/84

Final Date: 06/10/86

Deleted Date:

The Micro Storage/Intel Magnetics (commonly referred to as Intel Magnetics) site is a combined 3-acre facility that formerly produced and tested magnetic products and computer memories and was used for research and development and pilot manufacturing. 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 used a variety of toxic chemicals, primarily chlorinated organic solvents, which contaminated a shallow groundwater basin. Approximately 300,000 people within three miles of the site depend on groundwater as a source of drinking water. The drinking water is supplied from a deeper uncontaminated groundwater basin.

Investigation and Cleanup Activities

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. EPA is currently evaluating the current remedy and may select a new remedy in 2018 to help reach final cleanup. Groundwater monitoring will continue until cleanup goals are met.

Cleanup Results to Date

The construction of cleanup remedy 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.
