Project Details

Description

Nonaqueous phase organic liquids are widespread contaminants of
subsurface soils and groundwater. From a human health perspective, these
organic liquids are of particular concern because they tend to represent
long-term sources of pollution and create diverse and persistent pathways
for eventual human exposure. The work proposed in this project is
directed towards the investigation of processes which influence the
entrapment, persistence, transport, bioavailability, and toxicity of
organic liquid components in the natural subsurface environment. It
represents a fundamental research program which builds upon previous and
current NIEHS-funded projects and integrates laboratory and mathematical
modeling investigations. Subproject A focuses on the behavior of
benzene, toluene, xylene (BTX) and chlorinated solvent compounds. Its
specific aims relate to the investigation of the influence of physical
and chemical heterogeneities on organic liquid entrapment and mass
transfer, and the quantification of the influence of multiple, coupled
processes on contaminant fate and transport. Special attention will be
directed to the elucidation of microbial processes through close
collaboration with Project 1 investigators. Thus, the work proposed is
designed to logically extend the knowledge gained in previous NIEHS-
funded projects to consider the interaction of multiple processes, the
influence of chemical and physical heterogeneities on these processes,
and the behavior and fate of complex NAPL mixtures. Although directed
primarily at the investigation of naturally occurring attenuation
processes, the knowledge gained from these studies will have immediate
applications to the design of more effective remediation strategies.
