Western South Boundary GW Treatment System Begins Operating

September 2002

The Western South Boundary groundwater treatment system is located near the southwest site boundary. The system consists of two extraction wells to capture the highest concentrations of volatile organic compounds (VOCs) in the western-most portion of the Operable Unit III VOC plume that originates from the central portion of the BNL site. The system reduces off-site migration of the plume and reduces the potential for impacts to the Carmans River.

The system began operating September 2002 and groundwater modeling predicts that it will need to operate until 2014. Monitored natural attenuation will then be used to achieve drinking water standards by 2030.
