Redevelopment at the Site

The 75-acre Westinghouse Electric Corporation (Sunnyvale Plant) Superfund site is located in Sunnyvale, California. The Westinghouse Electric Corporation used the facility to manufacture electrical transformers. During this time, groundwater contamination resulted from a leaking storage tank and spills on site. Site investigations also found fuel and other contamination in area groundwater and soil. EPA added the site to the Superfund program’s National Priorities List (NPL) in 1986. Cleanup activities included the removal or paving of contaminated areas and the removal and treatment of contaminated groundwater. In 1996, Northrop Grumman purchased the site. The company is a U.S. defense contractor that employs nearly 1,000 people at the facility.
