%X Twenty-two sites on 14 former potato growing properties at Kinglake, Victoria, with similar soil type, topography and history of chemical use, were soil tested for organochlorine chemicals during 1987&#8211;88 and again during 1997&#8211;98. The 95% confidence limits for the decline in concentrations of dieldrin and DDT in the soil were 5.5&#8211;41.5% and 29.1&#8211;48.5%, respectively. There were no significant differences between farms in the rate of depletion of either organochlorine. Reductions in both to 1997&#8211;98 were not significantly associated with the concentration in 1987&#8211;88.
