Summary:A substantial number of chlorinated solvent ground-water plumes at hazardous waste sites are currently discharging, or may potentially discharge, into ecologically sensitive wetland environments. Although chlorinated solvents tend to be relatively resistant to degradation within most aquifer systems, rapid and complete transformations can occur within the organic-rich reducing environment typical of wetland sediments, indicating that monitored natural attenuation may be an effective remediation option for discharges of chlorinated solvent plumes into wetlands. A previous study by the U.S. Geological Survey in a freshwater tidal wetland at Aberdeen Proving Ground (APG), Maryland, showed complete attenuation of chlorinated solvents before the wetland surface or creek was reached. A collaborative study by the U.S. Geological Survey and the Air Force Research Laboratory under the Department of Defense Environmental Security Technology Certification Program was conducted to determine if the natural attenuation of chlorinated solvents that occurs at the APG wetland site can occur at wetland sites in different hydrogeologic environments and to assist in the transfer of this technology to other potential users. The objectives of the demonstration reported here were (1) to assess and compare the extent of natural attenuation of chlorinated solvents at the APG wetland site to an inland forested bog in the Colliers Mills Wildlife Management Area, near McGuire Air Force Base, New Jersey; (2) to demonstrate and compare different methods of sampling and analysis for collecting the site data needed to evaluate natural attenuation in wetlands; and (3) to develop a technical protocol for the assessment of natural attenuation of chlorinated solvent plumes discharging into wetlands. The APG site was used for the second objective of evaluating different methods of sampling and analysis appropriate for assessing natural attenuation in wetlands.
