Abstract: The article discusses the method of diagnosing soil contamination zones with electrically contrasting ecotoxicants, as well as methods for monitoring the processes of soil decontamination by geophysical methods. The calculation and modeling of the soil contamination zone was carried out when diagnosing by electrical exploration methods. According to the schemes of probing and profiling. The paper solves the direct and inverse problem of electrical exploration with a contamination zone in the form of a ball inside a homogeneous soil mass, while the main calculated dependencies were established, which describe the data obtained experimentally with the greatest accuracy. The algorithm proposed in this paper, based on the adaptive random search method, allows using the results of electrical profiling to quickly determine the contamination zone with electrically contrasting ecotoxicants: the depth of the location; the effective radius and assess the degree of contamination by the ratio of the specific electrical resistances of the anomalous zone and the host medium.
