The Advanced Micro Devices, Inc. Superfund site covers 6 acres in Sunnyvale, California. Advanced Micro Devices, Inc. (AMD) designed and made semiconductor devices at two buildings on site from 1969 to 1992. Facility operations contaminated soil and groundwater with volatile organic compounds, primarily trichloroethylene (TCE). EPA added the site to the National Priorities List (NPL) in 1986. EPA issued a Record of Decision in 1991 for the site, together with the TRW Microwave Inc. and Signetics Inc. sites, and an off-site area, or operable unit. AMD removed soil contamination and treated contaminated groundwater. A developer bought the site property in 2006, demolished the former AMD buildings, and built a public self-storage facility in 2007. Several other commercial businesses are also on the site; they are not located above groundwater with elevated TCE levels. Groundwater treatment and monitoring are ongoing. Vapor intrusion assessments at the self-storage facility did not show any evidence of unacceptable vapor intrusion. In March 2019, EPA finalized an agreement with Philips Semiconductors, Inc. for the adjacent Signetics Inc. site. This agreement will help expedite the cleanup of underlying groundwater contamination from the Signetics Inc. site that limits the effectiveness of cleanup efforts at the AMD site, address vapor risks in the community, and restore groundwater quality in the region.

The 25-acre Advanced Micro Devices, Inc. (Building 915) Superfund site is in Sunnyvale, California. Advanced Micro Devices, Inc. (AMD) made semiconductors at Building 915 starting in 1973. Sampling found contamination in groundwater wells near the building in 1981, caused by leaking underground tanks and spills. EPA added the site to the National Priorities List (NPL) in 1990. AMD removed contaminated soil and a 4,700-gallon underground acid neutralization system. AMD also put in a groundwater treatment system to remediate groundwater and prevent contaminants from migrating off site. AMD sold the site property in 2003 to a company that specialized in flash memory devices. It was active on site from 2005 to 2015. In 2011 and 2014, AMD did vapor intrusion investigations in Building 915. They did not find any evidence of unacceptable vapor intrusion due to site-related contaminants. A developer purchased the site property in 2016 and demolished all buildings. The developer then built townhomes with proactive mitigation measures integrated into their design and construction. These measures include vapor barriers and monitoring to confirm healthy indoor air.

The Applied Materials Superfund site is in Santa Clara, California. A large industrial building occupies most of the 9-acre area. Applied Materials began making semiconductor wafers in the building in 1974. Sampling found soil and groundwater contamination in 1983. Leaking pipes connected to underground tanks may have resulted in the contamination. Applied Materials put in a system to pump and treat contaminated groundwater in 1984. The company also removed underground storage tanks and nearby soil in 1985. EPA added the site to the National Priorities List (NPL) in 1987. The groundwater treatment system ran until 2002. Groundwater monitoring is ongoing. Applied Materials ended its research and manufacturing activities on site in 2003. Applied Materials then converted the building into offices and education facilities. Its corporate headquarters are now on site.

The Atlas Asbestos Mine Superfund site is in western Fresno County, California. The site includes two operable units: the Atlas Mine operable unit (Atlas Mine OU) and the City of Coalinga operable unit (City OU). The City OU is also part of the neighboring Coalinga Asbestos Mine Superfund site. The site also includes two areas of interest, the Clear Creek Management Area and the Arroyo Pasajero Ponding Basin. The 140-acre Atlas Mine OU includes the asbestos mine and tailings, a processing mill and support buildings. The mine was active from 1963 to 1979. During operations, some milling and mining products from Atlas Mine and the Coalinga Asbestos Mine were sent to the City OU prior to being processed and transported. Operations released asbestos into the soil, sediment, surface water and air. EPA added the site to the National Priorities List (NPL) in 1984. Cleanup activities for the Atlas Mine OU diverted streams around the contamination and trapped contaminated sediment, stabilized the sides of waste piles, dismantled the old mill, and used fencing to limit access to the area. Institutional controls restrict land use and potential site disturbances. Operation and maintenance activities, routine inspections, and air monitoring are ongoing. Cleanup activities at the City OU excavated contaminated soil and consolidated it in the underground Waste Management Unit. EPA deleted the Coalinga Asbestos Mine Superfund site (including the City OU) from the NPL in 1998. The Atlas Mine OU is in use as open space and ecological habitat. The City OU part of the site is in continued commercial, industrial, public service and residential use. Redevelopment across the city of Coalinga includes stores, restaurants, social services, medical offices and residential areas.

The Beckman Instruments (Porterville Plant) Superfund site is in Porterville, California. The 160-acre area includes the 12-acre Beckman plant property and nearby commercial, agricultural, and residential properties. The company made printed circuit boards and electronic instrument parts at the facility. From 1974 to 1983, facility operators disposed of wastes in an evaporation pond on site. This pond was the most likely source of groundwater contamination around the Beckman facility. Investigators also identified lead contamination in the soil. In 1985, Beckman began operating a groundwater pump-and-treat system. EPA added the site to the National Priorities List (NPL) in 1986. In 1989, cleanup addressed contaminated soil and expanded the groundwater treatment system. In 2005, EPA agreed to discontinue use of the groundwater treatment system and allow the groundwater to recover naturally. Groundwater contamination of 1,1-DCE continued to decline and by 2019 was below the cleanup level required by EPA. More cleanup to address lead-contaminated soil took place in 2016 and 2017. The Beckman plant closed in 2018. In May 2019 EPA took the 160-acre soil portion of the site off the NPL and in March 2022 took the groundwater off the NPL. There are no restrictions on the use of the former electronics plant property. Land use in the surrounding neighborhood includes residential, commercial and agricultural. A storage company now operates on site.
