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 Radford Army Ammunition Plant. Intact soil-cores were also collected from Anniston Army Depot, Milan Army Ammunition Plant, and Pueblo Army Depot results of these three studies are reported elsewhere. Soil columns were housed in controlled-environment chambers, and 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 biweekly. Columns were analyzed at 3-month intervals through 9 months. 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. Leachates contained no munition residues or transformation products TP. TNT, TNB TP, 2,4-DNT, 2,6-DNT 2-amino-DNT TP, and 4-amino DNT TP all migrated vertically but 7.5 cm 3 in. deep into the soil. Due to weathering, TNT, TNB, 2,4-DNT, and 2,6-DNT became bound within the soil A horizon.
