Redevelopment at the Site

The former Advanced Micro Devices, Inc. (AMD) 901/902 Thompson Place Superfund Site covers six acres in Sunnyvale, California. Between 1969 and 1992, AMD designed and fabricated semiconductor devices at two buildings at the site. The buildings were vacated by AMD in 1992 and remained vacant until the property was sold and redeveloped in 2007. Site investigations, which began in 1982, disclosed soil and groundwater contaminated with volatile organic compounds. EPA placed the site on the Superfund program’s National Priorities List (NPL) in 1986. Cleanup included removing soil contamination and treating contaminated groundwater. Groundwater treatment and monitoring are ongoing. In 2007, a developer bought the property and demolished the two former AMD buildings. The new property owner developed the former AMD facility area as a self-storage facility. Several other commercial and light manufacturing businesses also operate on the site.
