Hydrogeologic Effects of In-Situ Groundwater Treatment Using Biodegradation
Abstract
Subsurface contamination by organic compounds has become a major environmental problem at various U.S. Army installations. The technology exists to experiment with biological in-situ degradation methods of treatment and reclamation, but the factors controlling the chemical and physical environments of biodegradation are not well known and few site-specific case studies are documented in the engineering literature. The purpose of this study was to identify applicable in-situ groundwater treatment methods and performance criteria, and to help evaluate these techniques, especially with respect to limitations imposed by hydrogeologic conditions. Several in-situ biorestoration scenarios are described in the report, mostly with application to contamination in extensive sand aquifers. Evaluation of the various methods, however, is likely to be site specific, given the complexities of most geologic settings and groundwater systems. The application of in-situ schemes for clayey deposits or fractured rock are unknown. A major finding from this research is the potential effect of biofouling on the sit hydrology.
