Environmental Fate Studies on Certain Munitions Wastewater Constituents. Phase 5. Lagoon Model Studies

Abstract

This study was conducted to investigate the persistence of 2,4,6- trinitrotoluene (TNT) and hexahydro-1,3,5-trinitro-1,3,7-triazine (RDX) in waste disposal lagoons at Louisiana Army Ammunition Plant. The waste disposal lagoons are complex environments due to a heterogeneous distribution of solid TNT and RDX munitions on the lagoon sediment surface. These solids serve as a constant input source of munitions to the lagoon waters through dissolution. Flux rates for the dissolution of munitions were measured at .000108 cm/sec. for TNT and . 0000775 cm/sec. for RDX at 25 C in the lagoon.
