Description of Remedial Actions

Excavation of PCB-contaminated soil began at Building 96 in February 2000. Historically, Building 96 was a truck wash and vehicle maintenance facility during Camp Upton days. BNL used the facility as a drum storage area and scrap yard. Nearly 1,200 cubic yards of contaminated soil was removed. A groundwater treatment system to address volatile organic compound contamination was constructed and began operating in February 2001.

Since 2000, an additional 977 cubic yards of soil was removed and although the groundwater system was initially turned off, monitoring data has shown a stubborn source of contamination exists in area. Following several attempts to "unbind" the contamination in the soils, further characterization of the area was conducted in 2008.

In 2009, an Explanation of Significant Differences was submitted to the EPA requesting changes to the Record of Decision that included further excavation of soil. An area approximately 25 feet x 25 feet and 15 feet deep was excavated in September 2010. The soil was disposed of off-site. The groundwater treatment system for the contamination eminating from this site is expected to operate until 2016; monitoring will continue until 2030.
