NEXT PRB ACTION TEAM MEETING

The next PRB Action Team meeting will take place in Niagara Falls, New York, on October 15 and 16, 2003. The people who participated in this conference call have been assigned to organize three of the meeting's four topical sessions. Each of the participants provided an update on the status of his session:

• Source zone remediation. Bob Gillham, who is chairing this session, indicated that he has two speakers lined up--one from the University of Waterloo and one from DuPont. He also noted that Bob Puls knows of an additional speaker. Tom Krug said that someone from GeoSyntec could deliver a presentation on an emulsified nanoscale iron project that was performed in a source zone. Gillham said that he is thinking of asking people from the University of Waterloo to provide information on the general architecture and characteristics of source zones. Krug and John Vidumsky thought this was a good idea.



• Hydraulic effects. Vidumsky, who is chairing this session, said that he has identified the following potential speakers: Michelle Thomson, John Moylan, Stan Morrison, Lynn Morgan, Tom Sale, two URS representatives, and one representative from Rantec Corporation. From this list of eight people, Vidumsky said, he is confident that he can secure six presentations for the hydraulic effects session. He said that the session will require a half-day time slot.



• Novel applications. Krug, who is chairing this session, indicated that he has five or six potential speakers identified. Gillham and Vidumsky recommended contacting Tom Sale to find out whether he is interested in presenting a paper during the novel applications session. Krug said that the session will require a half-day time slot.

Call participants agreed that it would be ideal to have five or six presentations delivered per session. Vidumsky recommended allowing each speaker 20 minutes to present materials and 10 minutes for a question and answer session. If time allows, he said, it would be effective to have an open discussion period at the end of each session.
