Title: Behavior of Dense, Immiscible Solvents in Fractured Clay-rich Soils

Abstract

This research program addresses the nature and distribution of chlorinated solvent DNAPL sources in fractured clays and weathered shales, and the potential for natural attenuation of plumes derived from these sources. Specific objectives include: (1) Investigate the factors controlling migration of chlorinated solvent DNAPLs in fine-grained, highly structured soils and weathered shale bedrock. (2) Investigate the influence of ''matrix diffusion'' on the dissolution and apparent disappearance of residual DNAPL. (3) Investigate potential for biodegradation of chlorinated solvents in fractured and weathered shales at an existing contaminated field site and through the use of laboratory studies in microcosms and undisturbed columns of fractured shale saprolite. (4) Comparison of DNAPL behavior in different types of fractured clay-rich materials.
