Progress Report
First Quarter 2002


The Permeable Reactive Barriers Action Team is one of the six active Action Teams under the Remediation Technologies Development Forum (RTDF). The Permeable Reactive Barriers Action Team includes representatives from industry, government, and academia who share an interest in accelerating the development of cost-effective permeable barrier technologies.

This report documents progress of the Permeable Reactive Barriers Action Team during the first quarter of 2002.


  1. The Team outlined the scope of work for a two-year monitoring project to assess PRB performance and began identifying potential funding sources. Candidate sites for the proposed project would include Alameda Point, the U.S. Coast Guard Support Center in Elizabeth City, Denver Federal Center, the Somersworth Sanitary Landfill, and Seneca Army Depot. The number of sites chosen for the project will depend on available funding.
  2. A three-year, collaborative, long-term performance study conducted by the U.S. EPA, Department of Defense, and Department of Energy is nearing completion. Team members are developing a document that summarizes the activities of the three agencies, which may be issued as a tri-agency document. EPA is finalizing a second document on the study that is expected to be published in the Spring of 2002.
  3. Team members began investigating sources of support for development of a new state-of-the-science report on PRBs. If funded, the report would be prepared and issued in 2002.
  4. The next Team Steering Committee conference call is scheduled for April 3. The next Team meeting is expected to be held in October 2002 and will cover long-term performance, monitoring, site design, and cleanup efficacy.
