Impact/Purpose:
The purpose of this effort was to: 1) determine the applicability of an open air sampling methodology [14] to the first ever determination of emission factors from open detonations of metal-encased munitions and static firing of rocket motors; 2) determine distinctions in emissions from different methods of OB and OD disposal; and 3) develop methods for aerial sampling and quantification of semivolatile energetics. These data may be used in environmental health assessments for DoD demilitarizaton ranges.
Description:
Emissions from open detonation (OD), open burning (OB), and static firing (SF) of obsolete military munitions were collected using an aerostat-lofted sampling instrument maneuvered into the plumes with remotely controlled tether winches. PM2.5, PM10, metals, volatile organic compounds (VOCs), energetics, and polyaromatic hydrocarbons (PAHs) were characterized from 121 trials of three different munitions (Composition B (hereafter, “Comp B”), V453, V548), 152 trials of five different propellants (M31A1E1, M26, SPCF, Arc 451, 452A), and 12 trials with static firing of ammonium perchlorate-containing Sparrow rocket motors. Sampling was conducted with operational charge sizes and under open area conditions to determine emission levels representative of actual disposal practices. The successful application of the tethered aerostat and sampling instruments demonstrated the ability to sample for and determine the first ever emission factors for static firing of rocket motors and buried and metal-cased OD, as well as the first measurements of PM2.5 for OB and for surface OD.
