Environmental Studies on Open Burn/Open Detonation Disposal Sites. Transport and Fate of Nitroaromatic and Nitramine Explosives in Soils from Open Burning/Open Detonation Operations: Milan Army Ammunition Plant (MAAP)
Abstract
This report describes soil column experiments (task 1) used to study fate and transport of OB/OD residues within the upper 1 m of soil. (Terrestrial (task 2) and aqueous (task 3) toxicity studies are reported elsewhere.) Intact soil-cores were collected from MAAP and also from Anniston Army Depot, Radford Army Ammunition Plant, and Pueblo Army Depot; results of these three studies are reported elsewhere. Soil columns were housed in controlled-environment chambers. Each soil column was formulated to approximate the major OB/OD residues found at the respective sites. Synthetic rainwater was added to the columns twice weekly, and a controlled tension applied. Leachates were collected twice weekly. Columns were analyzed at 6.5-wk intervals through 26 wk. Columns were cut into 2.5-cm transverse sections, and subsamples were air-dried, ground, and extracted. Extracts and leachates were analyzed by HPLC for explosives to reveal fate and transport behavior. RDX and HMX, measurable throughout in leachates, averaged 0. 4 and 12 mg L-1, respectively; while 2,4- and 2,6-DNT averaged 0.63 and 0.67 mg L-1 through day 58. Soil RDX migrated the full soil-core length by 6.5 wk, while soil HMX took 19.5 wk. Soil 2,4- and 2,6-DNT remained within the top 15 cm (6 ), the A horizon.
