Davies analysed sediments from Barren Box Swamp, Yanco Main Drain, Cooragool Lagoon, and three rice farms. Alpha-BHC, Dieldrin DDE and DDD were detected in one or more of the soil samples from rice farms, with the highest concentration being 0.136 mg/kg of DDE (Table 26). Sediment samples from Yanco Main Drain and Cooragool Lagoon contained traces of DDE, DDD and DDT but not alpha-BHC or dieldrin (Table 27). Although Davies did not detect
organochlorine residues in sediment from Barren Box Swamp, Garbin (1992), in a separate set of
measurements, detected trace levels of DDT residues in both sediment and biota.
