An ice-water partition experiment using RDX and TNT was conducted to determine the efficiency with which the formation of ice excludes nonvolatile organic compounds. RDX and TNT are being used by CRREL as substitutes for volatile organics to see if freezing can move organics in saturated soils. Knowledge of the behavior of RDX and TNT, i.e., diffusivity and partition coefficient, is important for determining the conditions under which they, and the volatile organics of interest for hazardous waste cleanup, might be moved. TNT and RDX are excluded from the ice structure at freezing rates of up to 9 X 10 -5 cms3.1 in.day. An upper limit for the partition coefficient, K, was estimated using the measured effective partition coefficient and the growth rate of the ice.
