The facility occupies about 4 acres and is surrounded by industrial and business areas.
Contamination is believed to have resulted from leaking tanks.
About 300,000 people depend on wells within 3 miles of the site as a source of drinking water. This is one of 19 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 contaminate a common ground water basin. Although these sites are listed separately, EPA intends to apply an area-wide approach to the problem as well as take specific action as necessary. The company has installed and is operating a system to pump and treat the contaminated ground water.
