The main focus of this issue paper is to provide remedial project managers and corrective action project officers with a summary of information regarding the nature of munition constituents (MC) with an emphasis on energetic residues and metals at military training ranges and munitions open burn (OB) and open detonation (OD) demolition units. For this document, MC will refer to chemicals associated with military explosives and propellants. This will include some background on the physical and chemical properties of energetic chemicals and residues, how residues are deposited and amounts of residue produced from different detonations and firing activities, results of investigations describing the accumulation and distribution of residues at different types of military ranges and OB/OD units, a comparison of methods for the collection of representative soil samples on ranges, and a summary of laboratory methods designed to provide adequate characterization of these soil samples. White phosphorus is discussed in a case study in Appendix A1, but no other smoke munitions or illumination munitions will be discussed in this document.
