Mining tailings are the source of a wide range of chemical elements in the environment. One of the main mechanisms of substance migration is the filtration of solutions into groundwater and the river network. In this paper, we consider the results of geophysical studies along the side of the tailings mine production (Salair, Kemerovo region) by the method of Electrical resistivity tomography (ERT). The aim of the research was to identify the leakage of industrial water from a hydraulic structure, as well as to compare the geoelectric parameters of the environment with the geochemical testing of solutions near the tailings. It was found that the direction of the underground fluid flow from the tailings can be traced using geophysical methods, as well as to show the exact anomalous drainage zone on the profile of ERT.
