| Description: | Technical Report Abstract: Exposure assessment and risk management of explosives-contaminated soil, sediment, surface water, and groundwater require knowledge of the fate and effects of explosives and their transformation products in the environment. Most of the information available on fate and transport of explosives is for the subsurface environment. The information available for the subsurface shows that transfonnation and sorption are two of the most important environmental processes affecting the fate and transport of TNT. For RDX and other explosives, additional processes such as mineralization to CO2 may also be important while processes such as sorption may be less important. Redox potential strongly affects the rate and products resulting from explosives transformation. Sorption can be affected significantly by cation substitution on clay minerals, and competitive sorption can affect the mobility of explosives and their degradation products. Recent findings show that considerable work remains to be conducted, even in the subsurface. At present, we possess a good qualitative understanding of the processes that are operative in soils and aquifer materials and an inferential understanding of the processes that may be occurring in other environments. Translating this qualitative understanding and speculation into quantitative mathematical process descriptors is impeded by the nature of the information available and will require additional process level research. |
