Abstract
Technology for in situ remediation of undetonated explosive material. A bioremediating apparatus in the form of a storage chamber houses in moist condition type of microorganisms capable of metabolizing the explosive material. Examples of such microorganisms include Pseudomonas spp., Escherichia coli, Morganella morganii, Rhodococcus spp., Comamonas spp., and denitrifying bacteria. The bioremediating apparatus is joined with an explosive apparatus that houses a charge of explosive material. A solution released into the storage chamber by opening a first valve hydrates the microorganisms. The explosive assembly has an actuation means for opening the first valve and a second valve that releases the microorganisms from the storage chamber 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. The valves utilized are either mechanical, and thus opened by the coupling of the bioremediating apparatus to the explosive apparatus, or comprised of a slowly effacing material, such as gelatin. A micro-scale form of a bioremediating apparatus includes microorganisms encapsulated in gelatin for disposition mixed in or contacting the explosive material.
