 | This manual gives guidance on how to collect and process soil samples to quantify explosives, propellants, and metals from nonoperational ranges under remedial investigation. This document outlines how to estimate the average concentration of energetic compounds and metals in soils and determine the error in the estimated concentration. Since this guidance is for a remedial investigation, we assume that the Site Investigation has identified areas that need further study. |

 | A novel porous organosilicate material was evaluated for application as a solid phase extraction sorbent for preconcentration of nitroenergetic targets from aqueous solution prior to HPLC analysis. The performance of the sorbent in spiked deionized water, groundwater, and surface water was evaluated. Targets considered included 2,4,6-trinitrotouene, 2,4-dinitrotoluene. RDX, HMX, and nitroglycerin. The sorbent was shown to provide improved performance over Sep-Pak RDX. The impact of complex matrices on target preconcentration ... |

|
 | Field observations of weathering Comp B (RDX/TNT 60/40) residue were made on a live-fire training range over four years. The Comp B residue was formed by low-order detonations of 120-mm mortar projectiles. Physical changes were the disaggregation of initially solid chunks into masses of smaller diameter pieces and formation of red phototransformation products that washed off with rain or tidal flooding. Disaggregation increased the surface area of the residue, thereby ... |

| Energetic Residues from Field Disposal of Gun Propellants |

|
 | Military training with howitzers and mortars produces excess propellant that is burned on the training range and can result in point sources containing high concentrations of unreacted propellant constituents. Propellants contain energetic compounds such as nitroglycerin (NG) and 2,4-dinitrotoluene (2,4-DNT), both of which are found at firing positions and propellant disposal areas. To quantify the mass of residue remaining from the field-expedient disposal of propellants, two mortar propellants and one ... |

| Energetic Residues from the Expedient Disposal of Artillery Propellants |

|
 | Military live-fire training missions utilizing mortars and howitzers frequently generate excess propellant charges. Disposal of this propellant is often done on-site and is referred to as expedient disposal. Investigations into energetics residues resulting from expedient disposal of propellants began in 2002 with the collection of residues inside and outside a propellant burn structure. These residues contained very high concentrations of 2,4-Dinitrotoluene, an indication that the burning process was not complete. ... |

 | The Military maintains sustainability and environmental stewardship responsibilities for training ranges. One of the environmental challenges is to monitor the surface loading of energetic residues. Method 8330B, which was developed to assist in this task, recommends the use of a MULTI INCREMENT(registered trademark) sampling strategy and total sample processing prior to subsampling and analysis. This demonstration/validation project evaluated scientifically defensible sampling and sample-processing protocols used for the characterization of energetic ... |

| Energetic Residues from Blow-in-Place Detonation of 60-mm and 120-mm Fuzed High-Explosive Mortar Cartridges |

|
 | Military live-fire training missions frequently result in unexploded ordnance on training ranges. Disposal of the rounds, often done in situ, is necessary in some cases for range safety or maintenance. In February 2008, the U.S. Army Cold Regions Research and Engineering Laboratory teamed with the 716th Explosive Ordnance Disposal detachment at Fort Richardson, AK, to detonate two series of seven 60-mm and 120-mm fuzed high-explosive (HE) rounds to determine the ... |

|
 | Fourteen 120-mm high-explosive mortar projectiles were fired into the Eagle River Flats (ERF) impact area in June 2007 to determine physical disturbance of the mudflat when it is not covered by ice. Currently, ERF is used only when it is covered by ice that prevents disturbance of the underlying sediment. Thirteen of the projectiles functioned normally and produced high-order detonations. The high order detonation craters averaged 2.7 m in diameter ... |

 | Over the past two years, the U.S. Army Engineer Research and Development Center and the Defence R&D Canada Valcartier have partnered to develop an improved understanding of the distribution and fate of propellant residues on military training ranges in SERDP Project ER-1481. As a portion of this work, field studies have been conducted to estimate the mass of propellant residues deposited per round fired from various munitions. This research included ... |
