NOVELTY Remediation of explosives contaminated soil using a natural micro-organism source. DETAILED DESCRIPTION Remediating explosives contaminated soil comprises:(a) maintaining an anaerobic bioremediation mixture comprising explosives contaminated soil, at least one natural micro-organism source and at least one oxidizale carbon source under anaerobic conditions for a time to convert at least a portion of the explosives contaminants into reduced derivative compounds to give an anaerobic bioremediation product;(b) preparing an aerobic bioremediation mixture by combining the anaerobic bioremediation product with at least one compostable material; and(c) maintaining the aerobic bioremediation mixture under aerobic conditions for a time to give a remediated soil product in which at least some of the reduced derivatives compounds have been converted into humic compounds. BIOLOGY The anaerobic bioremediation mixture includes 5-50 weight% natural micro-organisms source, preferably animal manure and/or anaerobic digester sludge. The aerobic bioremediation mixture includes 33-75 volume% at least one compostable material.EMBODIMENT - The remediated soil is site specific or unrestricted soil. The weight of explosives contaminants in the remediated soil is at least 90% less than the weight of the explosives contaminants found in the explosives contaminated soil. The anaerobic bioremediation mixture is maintained at a moisture level of 50-100% of the mixture's holding capacity and preferably contains 0.5-5 weight% oxidisable carbon source, preferably purified carbohydrate, natural carbohydrate, starches derived from agrochemical products or starch containing agrochemical products, especially comprising 1.0-2.0 weight% dextrose. The compostable material comprises grass clippings, yard waste, municipal sold waste and/or landfill compostable materials. Step (a) occurs in a vessel. ACTIVITY Digestion; Microbial; Biotechnology;    USE -   For remediating explosives contaminated soil. The product can be used as a landfill cover material.    ADVANTAGE -   The method is simple an safe and effectively converts hazardous nitroaromatic compounds such as trinitrotoluene and nitramine contaminants into less hazardous and/or non-hazardous substitutes. EXAMPLE 100 tons soil contaminate with TNT, RDX and HMX were combined with 15 tons cow manure, a5 tons anaerobic digester sludge, 1.3 tons potato waste and 1.3 tons dextrose using a window turner. The mixture was placed in a pit and water was added to increase the moisture content of the mixture to near saturation. The top surface of the mixture was covered with a spray on cover material. After 138 days the mean TNT concentration was 61 mg/kg (97% conversion) and the mean RDX concentration was 449 mg/kg (46$ removed). DESCRIPTION OF DRAWINGS The figures shows the concentration of TNT, monoaminonitrotoluene and diaminonitrotoluene reduction products versus time during the anaerobic phase described in the example.
