SITE BACKGROUND

Advanced Micro Devices, Inc. makes semiconductor and microprocessor devices at this 5.5-acre site. Building 915 was built on former agricultural land in 1973. At that time, three underground acid neutralization tanks were installed north of the building. The building's operations also involved underground storage tanks of waste organic solvents. In 1981, the company identified volatile organic compounds (VOCs) in wells near the building. VOCs are compounds used in many applications, such as dry cleaning, paint stripping, metal plating and machinery degreasing. High levels of VOCs present in the on-site soils resulted from leaking tanks and spills during solvent handling. Following construction of the site’s remedy, ground water treatment and monitoring are ongoing.
