Abstract:

This report describes soil column experiments task 1 used to study fate and transport of OBOD 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 OBOD 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.
