SUMMARY OF THE REMEDIATION TECHNOLOGIES DEVELOPMENT FORUM
PERMEABLE REACTIVE BARRIERS ACTION TEAM
STEERING COMMITTEE CONFERENCE CALL

11:00 a.m.-12:00 p.m.
August 15, 2002

On Thursday, August 15, 2002, the following members of the Remediation Technologies Development Forum's (RTDF's) Permeable Reactive Barriers (PRB) Action Team met in a conference call:

Bob Puls, U.S. Environmental Protection Agency (Action Team Co-chair)
Bruce Sass, Battelle
Tim Sivavec, General Electric Corporate Remediation
Stephen White, U.S. Army Corps of Engineers

Also participating in the call were Carl Spreng of the Colorado Department of Public Health and the Environment and Christine Hartnett from Eastern Research Group, Inc. (ERG).

THE NEXT PRB ACTION TEAM MEETING

The next PRB Action Team meeting will be held in conjunction with the Interstate Technology and Regulatory Cooperation (ITRC) conference that is scheduled to take place November 6 through 8, 2002, in Washington, D.C. Call participants expressed interest in holding three sessions: (1) a Steering Committee meeting, (2) a general meeting, and (3) a poster session.

Steering Committee Meeting

Bob Puls said that the PRB Steering Committee will meet on the evening of November 5, 2002. A small room will be reserved to accommodate the group.

The General Meeting

The RTDF's general meeting is scheduled for:

• November 6. Blocks are reserved for 8:00 a.m to 12:00 p.m and 1:15 p.m. to 4:00 p.m.
• November 7. Blocks are reserved for 9:45 a.m to 11:45 a.m. and 1:00 p.m. to 3:00 p.m.

The general meeting will consist of four sessions:

• PRBs and cleanup efficacy. Puls has already started identifying speakers for this session. He is trying to line up speakers who have worked on the following sites: Somersworth, Elizabeth City, Rocky Flats, Warren Air Force Base, Denver Federal Center, and a site in Australia. Puls said that John Vidumsky suggested having someone speak about DuPont's North Carolina site as well.



• Long-term performance. Bruce Sass said that he is compiling a list of potential speakers for this session. The list includes Rick Wilkins, Lynn Roberts, Bob Gillham, Libby West, Liyuan Liang, and Stan Morrison. Sass said that he also plans to ask representatives from Battelle and Parsons Engineering Science to give presentations.



• Site design. Puls said that Vidumsky has identified the following as potential speakers for this session: Stephen Shoemaker, Grant Hocking, Tom Sayles, Lynn Morgan, David Lee, and a representative from GeoSyntec Consultants.



• Monitoring. Tim Sivavec said that he and Gillham are working together to identify speakers for this session. They hope to invite speakers from Battelle, the University of Waterloo, and Johns Hopkins. Sivavec said that efforts are also being made to contact a company that is working with colloidal borescopes. In addition, efforts will be made to identify someone to speak about diffusion samplers. Sivavec said that he plans to ask someone from the Somersworth site to deliver this presentation. Puls said that Vidumsky also knows someone (i.e., Michelle Thomson) who could speak about diffusion samplers. Sivavec will talk to Vidumsky about this.

Carl Spreng, who leads the ITRC's Radionuclides Work Group, said that the long-term performance session is of particular interest to his work group. He also said that his work group would only be able to participate in the RTDF meeting during the morning of November 6 or the afternoon of November 7. Puls said that an effort will be made to schedule the long-term performance session for one of these time slots.

Call participants agreed that it would be ideal to allow 30 minutes per presentation. If six speakers are identified for each thematic session, however, the time slots reserved for the RTDF meeting will prove insufficient. As a result, Puls said, it may be necessary to schedule fewer than six speakers for some of the thematic sessions. He and Sivavec discussed limiting the monitoring session to four speakers.

The Poster Session

Call participants expressed strong interest in holding a poster session on the night of November 6, 2002. Puls asked ERG to determine whether this would be possible and how much space would be available for the session. ERG agreed to follow up on this action item as soon as possible.

ACTION ITEMS

• Stephen White said that the ITRC has a Diffusion Samplers Work Group. He agreed to contact the work group to let them know about the PRB Action Team's monitoring session.



• Those who have been assigned to coordinate the meeting's thematic sessions (i.e., Puls, Vidumsky, Sivavec, Gillham, and Sass) will continue to identify speakers and work on the agenda. Puls asked all of the coordinators to keep him abreast of who has agreed to speak at the meeting.



• Puls will develop a rough draft of the meeting's agenda and distribute it for comment.



• ERG will send meeting announcements to the entire RTDF PRB Action Team mailing list.



• ERG will communicate with ITRC representatives to coordinate logistics for the joint ITRC-RTDF meeting.
