Abstract The paper presents the data on 8-year monitoring of the remediation of disturbed lands and the assessment of the effectiveness of biological treatment of oil-polluted soils. The positive effect of the clean-up work was clearly saw annually for only one summer season. An increase in the level of pollution by the beginning of each next season was most likely due to the oil migration from the underlying soil horizons to the near-surface ones. The data obtained on chemical composition of the soil samples taken from a depth of up to 100 cm showed, that oil content was 2 times higher than on the surface. With depth increasing the amount of hydrocarbon components had become more in the composition of soil extracts, while the content of resins and asphaltenes had decreased. This could mitigate the positive effect of reclamation work.
