(ZA9607883-A)      A process for cleaning soil, containing DDT-type contaminants and a population of viable aerobic/anaerobic microbes capable of transforming DDT-type contaminants into harmless materials and being viable under both anaerobic and aerobic conditions, comprises:    (a) forming a degradation zone comprising the soil;    (b) maintaining the zone at a temperature of 15-37 C and maintaining the degradation zone microbes population counts of 105 cfu/g anaerobic and aerobic bacteria;    (c) supersaturating the degradation zone with water;    (d) rendering the zone anaerobic;    (e) maintaining the zone supersaturated with water and at a redox potential level below negative 200 mV until a significant amt of DDT type contaminants is degraded;    (f) oxygenating the zone to render it aerobic;    (g) maintaining the zone at a redox potential level above positive 100 mV until a significant amount of DDT type contaminants is degraded, and    (h) repeating steps (c) through (g).    Advantage - DDT is converted into harmless materials and the soil can be decontaminated to the extent desired.
