| Abstract | The 14-acre Commodore Semiconductor Group (CSG) site is a manufacturing facility in Norristown, Montgomery County, Pennsylvania. Land use in the area is residential, commercial, and industrial with a wetland area located within 1 mile from the site. The site overlies a Class IIA aquifer that is used as a source of drinking water. From 1969 to present, the owners, including CGS, used the site to manufacture semiconductor chips. A concrete underground storage tank was installed adjacent to the southeast side of the building to store a waste solution known to contain TCE and other solvents generated from the manufacturing process. The concrete tank was reported to have leaked in 1974. In 1984, further state and EPA investigations confirmed contaminants onsite in ground water and drinking water. The ROD addresses the contamination of onsite ground water and drinking water. The primary contaminants of concern affecting the ground water are VOCs, including PCE and TCE. |
