Summary

Combines a timely review of the current understanding of subsurface contaminant transport and remediation with an insightful discussion of critical issues that demand future consideration. Presents in one volume the results of research from a variety of disciplines, including chemistry, chemical engineering, materials science, and environmental science. Delineates the state of the science in colloidal, interfacial, and surfactant phenomena influencing natural migration and remediation of contaminants in the subsurface. A panel discussion indicates critical research needs relative to extending our understanding and management of soil and ground water resources.
