Abstract : The purpose of this report was to improve the effectiveness of enhanced biodegradation methods to decontaminate soils and ground waters polluted by JP-4 jet fuel spills. Laboratory studies were conducted to improve nutrient formulations, reduce in situ precipitation and test potential stabilizers for hydrogen peroxide. This laboratory study has investigated the geochemical reactions which cause aquifer plugging and tested several phosphate compounds with improved solubility characteristics. Trimetaphosphate was shown to be least reactive with soils and exhibited the best groundwater transport. Several stabilizing agents for hydrogen peroxide were tested in batch and column studies. Only citrate showed promise as a stabilizing agent in batch studies, however, its performance in an aquifer simulator was unimpressive. The laboratory procedures and geochemical models used in this project can assist scientists and engineers in determining the feasibility of site specific applications of this technology. (ttl)
