The fate of jet fuel JP-8 was studied in quiescent flask test systems containing water, watersediment slurries and soil. For each treatment, killed samples were compared to active samples to assess the relative contributions of biodegradation and volatilization in removing JP-8. At appropriate time intervals, flasks were extracted with CS2 and analyzed by gas chromatographymass spectrometry. In water and watersediment slurries. the major removal process was evaporation. No significant differences were noted between active and sterilized flasks, indicating that biodegradation was not a major factor in removal of JP-8 under these test conditions. When removal in water alone was compared to removal in watersediment slurries, greater losses were observed in water alone, indicating that the presence of sediment sequesters the jet fuel rendering it less susceptible to volatilization. Removal of JP-8 from active soil was not significantly different from removal in sterilized soil, indicating that in soil as well as water, biodegradation does not play a significant role in removal of jet fuel. Toxicity of JP-8 to microorganisms was assessed by measurement of glucose and hexadecane mineralization. Microbial activity in water was inhibited by JP-8 whereas activity in water sediment slurries was enhanced by addition of JP-8.
