This videotape program provides an introduction to the basic concepts behind bioremediation, an overview of how the technology is currently being used, a perspective on the future potential of the technology, and answers to some commonly raised questions about bioremediation. It is targeted to a technical audience, particularly those involved with environmental issues, but does not assume any prior knowledge of biological processes. The objective of the program is to familiarize the viewer with the essential concepts of this technology and to provide a basis for understanding technical discussions in this area. It should be useful for engineers, scientists, managers, site owners, and regulators involved in site remediation.
