Recent research has led to a better understanding of the complex chemical and physical processes controlling the movement of contaminants through the subsurface, and the ability to pump such contaminantsto the surface. Understanding these processes permits the development and use of better site characterization technology and the design and implementation of more effective and efficient site remediation programs.

This document is an interim product of a research project that is developing a protocol for evaluating the effectiveness of ground-water remediations. It has been reviewed by members of EPA’s Robert S. Kerr Environmental Research Laboratory.
