(ZA9607884-A)      Decontamination of soil contg. DDT (1,1,1-trichloro-2,2-bis (p-chlorophenyl)ethane) type contaminants and populations of viable anaerobic and aerobic microbes capable of transforming the contaminants into harmless materials and viable under anaerobic and aerobic conditions comprises: (a) admixing the soil with amendment material to form a solid compost mixt. contg. organic nutrient materials; (b) composting the soil while maintaining the temp. of the mixt. at 20-65 C and the water content at 40-100% WHC; (c) during the composting maintaining the redox potential of the mixt. below -200 mV until a significant amt. of DDT-type contaminants is degraded, and (d) oxygenating the mixt. to increase the redox potential of the mixt. to above +100 mV and maintaining the redox potential at above +100 mV until a significant amt. of DDT type contaminants is degraded.    USE -   The process is used for partially decontaminating or completely remediating soil and/or sediments to produce harmless materials.    (JP10510470-W)      Decontamination of soil contg.
