| Abstract |
The 7-acre Raymark site is an active metal manufacturing and electroplating plant in the Borough of Hatboro, Montgomery County, Pennsylvania. The site is in an industrial area. As part of the rivet manufacturing process at the plant, VOCs, including 30 to 40 gallons of TCE, were used daily at the site to clean and degrease metal parts. The EPA discovered TCE in the Hatboro public water supply wells. Further EPA site investigations from 1980 to 1987 identified TCE in soil and other wells onsite and adjacent to the property and seem to indicate that contaminants from the site may have been at least a contributing source of contamination in the downgradient public water supply wells. Other chemical contaminants identified in samples from the public water supply wells, including TCA, did not seem to originate at the site, thus indicating several distinct sources for the contamination. The Record of Decision (ROD) addresses contaminated drinking water and ground water, which are referred to as Operable Units 2 and 3 (OU2 and OU3), respectively. The soil/source contamination (OU1), will be addressed in a subsequent ROD. The primary contaminants of concern affecting the ground water are VOCs including TCE and PCE. |
