Fate of Organic Chemicals in Subsurface Environments
Release of various synthetic organic compounds to the environment has caused soil and ground-water pollution in many places. The processes which control the persistence and movement of these materials are not well understood. A better understanding is necessary to aid in construction of models to predict movement and fate of pollutants in the subsurface and for design of control and abatement techniques. Project objectives are to determine the transformation pathways of selected organic compounds using a combination of field observations and laboratory simulations of environmental conditions; assess the relative importance of physical, chemical, and biochemical processes in the transformation of these compounds under ambient conditions; and study relevant biotransformation processes occurring in the subsurface.
