Agenda

A meeting will be held at LBNL to discuss the topic of coupled hydrogeological-biological-geochemical-thermal processes, including their recognized and potential impact on subsurface contaminant transport and remediation, and what some of the grand challenges are with respect to experimentation and modeling. Through presentations and discussion, we will highlight which processes and process interactions are particularly important for improved remediation of DOE contaminants.

Discuss the questions posed earlier by George Redden, and comment on the following general questions:

  • What are the general capabilities that, if available, would facilitate new advances in understanding and modeling of coupled processes?
  • What needs to be done that can not be done without consolidation of resources and expertise?
  • What research strategies should be suggested to develop a better understanding of the role of coupled processes and how to utilize lab-scale information for field-scale remediation?
  • Discuss the possibility of a National 2004 Coupled Processes Workshop.
4:00 ADJOURN. Closing statements by all participants
