National Semiconductor Corporation Public Health Assessment

Timeframe: 1991 to 1993

The National Semiconductor Corporation, located in Santa Clara County, California, was the site of several underground acid waste and solvent tanks that leaked volatile organic compounds, semi-volatile compounds, and metals into the subsurface soils and groundwater. After the discovery of similar contamination in neighboring areas, a group of environmental, labor, and other organizations concerned about groundwater contamination formed the Silicon Valley Toxics Coalition (SVTC) to address concerns at the site. The California Department of Public Health engaged IAI to provide community relations and education support for their public health assessment. IAI staff met with the SVTC and community leaders, developed educational materials, and provided consultation for the investigation. The study did not indicate that people had been exposed to levels of contamination that would be expected to cause adverse health effects.
