The Fairchild Semiconductor site is a former semiconductor manufacturing facility in San Jose, California. In late 1981, Fairchild discovered that an underground organic solvent waste tank had failed, resulting in soil and on- and offsite ground water contamination. Fairchild has been investigating and cleaning up soil and ground water pollution at the facility since contamination was first detected in 1981. The primary contaminants of concern affecting the soil and ground water are VOCs including PCE, TCA, DCE, and xylenes. The selected remedial action for the site includes onsite soil vapor extraction (aeration); onsite shallow ground water and offsite ground water pumping and treatment using air stripping, followed by offsite reinjection of treated ground water and discharge to surface water after aquifer reuse capacity has been exhausted; deep ground water from offsite, followed by discharge of untreated ground water to surface water via storm drains; conducting laboratory and field study of biodegradation of onsite chemicals; implementing institutional controls including deed restrictions to limit ground water and land use; and ground water monitoring.
