An analysis of the bioremeditation of explosives in contaminated soil

The contamination of soil and water with residues of explosives is a widespread environmental problem in large military complexes (gorontzy et al, 1994) the manufacture, processing, and packaging of 2,4,6-trinitrotoluene (tnt) and other explosives at military ammunition plants over several decades have resulted in high concentrations of this contaminant in soils at ammunition production sites ( widrig et al, 1997 . 14,800 tons of soil contaminated with tnt (2,4,6-trinitrotoluene), rdx (hexahydro-1,3,5-trinitro-1,3,5-triazine) and hmx (octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine), and (2) us naval submarine base, bangor, washington, for 2,200 tons of tnt -contaminated soils. Explosives contamination problem at some department of defense facilities from an analytical chemistry perspective, with emphasis on the compounds found in explosives-contaminated soils, and the laboratory. In the us, the army alone has estimated that over 12 million tons of soil have been contaminated with explosives, and the impact of explosives contamination in other countries is of similar magnitude.

In situ bioremediation of soil contaminated with explosives was studied using columns packed with contaminated soil several operating strategies were investigated, including continuous flooding of the soil column with dilute molasses or succinate solution, and periodic operating cycles consisting of flooding followed by draining and aeration. 33 composting explosives contaminated soil by white rot fungi - mass balance analysis of xenobiotica and quality of the bioremediated soil 34 bioremediation of tnt contaminated soil with fungi investigations in. This paper evaluates the results of 15 bioremediation treatability studies conducted at eight sites for explosives-contaminated soils, and discusses the full scale remedial implementation status five types of biological treatment processes have been evaluated: (1) composting, (2) anaerobic bioslurry, (3) aerobic bioslurry, (4) white rot fungus treatment and (5) landfarming.

Bioremediation of explosive contaminants type explosive contaminants in soil environments as well give a brief description of several research projects that were recently conducted in this area the review begins by first discussing leading to approximately 12 million tons of soil being contaminated by the waste generated during. The manufacture load, assembly and pack (lap) demilitarization washout operations and open burn/open detonation (ob/od) of ordnance and explosives has resulted in contamination of soils with munitions residues. Bioremediation is a new, efficient, environmentally friendly, and low-cost technology, which uses microorganisms to clean up soil contaminated with heavy metals and organic contaminants such as solvents, crude oil, explosives, and other toxic compounds from contaminated environments.

Laboratory and analytical methods for explosives residues in soil mariannee walsh,thomasf jenkins, andphilipg bioremediation of munitions-contaminated soil is the focus of intensive laboratory and analytical methods for explosives residues in soil.

Bioremediation of explosives contaminated soils located on grounds used for military activities offers an additional challenge with respect of the very availability of the soil itself, when it has. Explosives-contaminated soils, and discusses the full scale remedial implementation status five types of biological treatment processes have been evaluated: (1) composting.

And open burn/open detonation (ob/od) of ordnance and explosives has resulted in contamination of soils with munitions residues the primary constituents are nitroaromatic and nitramine organic compounds and heavy metals a number of sites have soil contamination remaining where waste disposal practices were discontinued 20 to 50 years ago.
