Abstract. The article analyses promising methods for treatment of oil-contaminated soils. The main tried and tested groups of oil-contaminated soil treatment methods are reviewed and concrete examples are given. The most promising group of currently used methods has been identified.

The authors performed an analysis of accidents accompanied by an accidental oil or oil product spill, considered the main causes of such accidents and their consequences for the environment components using concrete examples of real organizations. The analysis established that the most frequent accidents are caused by failure and depressurization of devices as well as by human errors expressed in the violation of industrial safety requirements and the requirements of the organization of hazardous works. The analysis of the main methods of oil-contaminated soil treatment is presented, the main drawbacks and the negative impact on the environment components are identified. Based on the obtained data, the most promising method with the highest efficiency and the least impact on the components of the environment has been identified. The main groups of methods used to clean the contaminated soil are chemical and biological methods. It is revealed that the most promising group of methods are biological methods, which is associated with a minimal impact on the atmospheric air, as well as a high degree of purification.

In addition, modern bioremediation and phytoremediation methods are considered in the article. The considered methods are based on the use of modern biopreparations and agrotechnical methods. These methods are based on an integrated approach, which leads to high efficiency. However, it should be noted that a high degree of treatment requires the maintenance of certain soil parameters such as temperature, moisture, acidity and mineral matter concentration.
