Transport of RDX and TNT From Composition-B Explosive During Simulated Rainfall.

A complete understanding of the fate of munitions constituents (MC) on U.S. Army training lands is needed to develop the fundamental framework for the contaminant transport, transformation, and fate (CTT&F) model for predicting the impacts of training activities on the distribution of MC in the environment.  Explosive compounds RDX, TNT, and HMX derived from Composition-B explosive are of particular concern due to their toxicity potential and widespread use.  Distribution of these compounds from particulate Comp-B exposed to rainfall was determined in the laboratory using a rainfall simulator.  Results will be discussed.
