Abstract
The 80-acre Mesa Area Ground Water Contamination site is a semiconductor manufacturing facility in Mesa, Maricopa County, Arizona. Land use in the area is predominantly industrial and residential. The site overlies two aquifers: a Lower Alluvial Aquifer (LAA), which is used by the residents of Mesa as a drinking water source, and an Upper Alluvial Aquifer (UAA). Since 1966, Motorola, Inc., has used the site for the production of semiconductors and the storage of chemicals in an underground storage system. The selected remedial action for the site includes treating shallow onsite soil using soil vapor extraction, controlling VOC emissions using carbon adsorption, followed by offsite disposal of carbon residuals; onsite and offsite pumping of contaminated ground water; treating the ground water onsite using vacuum degasification, followed by carbon adsorption to remove VOCs; discharging the treated water from the degasifier to the deionized water treatment plant for reuse in manufacturing and other facility processes; and disposing of remaining wastewater at a publicly owned treatment works.
