Phase II Tungsten Fate-and Transport Study for Camp Edwards
Abstract
Tungsten was detected in soil and groundwater beneath the Bravo Small Arms Range (SAR) at Camp Edwards, Massachusetts. This discovery prompted additional studies to assess tungsten's fate-and-transport. Installation of drive points and groundwater monitoring wells at three SARs [Bravo (B), Charlie (C), and South East/South West] indicate that groundwater contamination is restricted to B Range. Although tungsten is still present in groundwater monitoring well MW-72S at Bravo Range, concentrations have dropped significantly since the removal of soil and have stabilized at a less than 2 microng/L concentration. Soil remediation consisted of removal of all berm soil that contained tungsten with a level greater than 150 mg/kg. Similarly, shallow lysimeters installed at B, C, and India Ranges also indicate a decline in tungsten levels post-soil removal. Deep lysimeters at B range, installed after soil removal activity, indicate that tungsten is present in pore water at least 7.6 meters below ground surface.
