AbstractLive‐fire training activity dating from around 1941 to 1997 resulted in the deposition of spent

munitions, propellants, and explosives in impact‐area soils at the Camp Edwards Training Ranges on the

Massachusetts Military Reservation. Resulting contaminants of concern, including RDX, HMX, TNT, and

2,4‐DNT, are found in particulate form and are heterogeneously dispersed in the soil. An Innovative

Technology Evaluation (ITE) Program was initiated by the Army National Guard in March 2000 to

investigate the potential for remediation of these soils.Remediation technologies chosen for the ITE program to address this problem included soil washing,

low‐temperature thermal destruction (LTTD), composting, solid‐phase bioremediation,

bioslurry, chemical oxidation, and chemical reduction. The soil washing process was shown in field trials to

reduce the volume of soil requiring further treatment by 75 percent. All technologies were effective on soils

that had been treated using soil washing. LTTD, solid‐phase bioremediation, and bioslurry were effective

on untreated soil, while composting was less effective, and chemical reduction and oxidation were not tested on

untreated soils. © 2002 Wiley Periodicals, Inc.*
