The article deals with the actual problem of cleaning and remediation of soils contaminated in oil industry. The transmission of a small electric current through polluted soil leads to a decrease of pollutants concentration because of various processes. The paper presents the results of the study of changes in soil characteristics as a result of passing the electric current. Such parameters as the content of chlorides and organic matter of the soil (humus), electrical conductivity, density and soil moisture were studied. The research showed that carrying out low amperage electricity through the soil contaminated with oil and highly mineralized reservoir waters using does not entail critical changes in the soil properties. It was proved that this method can be effectively applied on various soils of oil fields and will not impede the subsequent restoration of plant communities at the treatment site.
