(ZA9709369-A)      Decontamination of soil containing cyclic organic compound contaminants (A) and populations of microbes viable under both anaerobic and aerobic conditions and capable of transforming (A) into harmless materials, comprises: (a) mixing the soil with amendment material (B), to form a mixture containing organic nutrient materials; (b) composting the mixture at 20-65 C, water content 40-100% water holding capacity, while maintaining the redox potential below negative 200 mV until significant amount of (A) is degraded; and (c) oxygenating the mixture to raise redox potential and maintain it at above positive 100 mV until significant (A) is degraded.    (A) consists of chlordane, dieldrin, toxaphene, aldrin, endrin, heptachlor, heptachloroepoxide, methoxychlor, and/or , , and/or hexachlorides.    USE -   By using both anaerobic and aerobic steps, the contaminants, e.g. toxic pesticides, are largely or completely converted to harmless products in an inexpensive manner. Material (B) is generally agricultural waste or municipal waste sludge.
