ABSTRACT:
Technology for in situ remediation of undetonated explosive material. An explosive apparatus contains an explosive material in close proximity with microorganisms. An explosive mixture capable of self remediation in the form of an explosive material is intermixed with microorganisms. The microorganisms are either mobile or temporarily deactivated by freeze drying until rehydrated and remobilized. The microorganisms are capable of metabolizing the explosive material. Examples of such microorganisms include Pseudomonas spp., Escherichia spp., Morganella spp., Rhodococcus spp., Comamonas spp., and denitrifying microorganisms. A bioremediation apparatus that contains microorganisms and prevents contact between the microorganisms and explosive material is joined with an explosive apparatus that houses a charge of explosive material. A barrier is actuated by mechanical, electrical or chemical mechanisms to release the microorganisms into the explosive assembly to enable the microorganisms to begin metabolizing the explosive material, when the explosive apparatus is joined with the bioremediating apparatus. If the explosive material fails to detonate, the explosive is remediated by the action of the microorganisms. Remediation includes both disabling of the explosive material and detoxification of the resulting chemical compositions.
