Superfund Ground Water Issue: Facilitated Transport August 1989

Idealized laboratory experiments reported in the literature have been designed to simulate specific physical and chemical conditions. These laboratory conditions have allowed researchers to control the variables which affect the behavior of contaminants in the subsurface and to identify the mechanisms which are likely to occur in the field. An understanding of the various mechanisms of facilitated transport will provide a more thorough understanding of the fate and transport of contaminants in the ground water and ultimately will provide the framework for further development of ground-water remediation technology. The following is a brief technical overview of facilitated transport prepared in support of the Regional Superfund Ground Water Forum.
