In the broad problem of the negative impact of the mining and processing industry waste on the environment, researchers pay special attention to the distribution, behavior, patterns of transport and deposition of arsenic as a particularly dangerous element with a high migration ability. The abstracts describe the behavior of the main pollutants on the maps of the Khovu-Aksy burial site. In the stored waste of hydrometallurgical processing of arsenide Cu-Ni-Co-ores over the years of storage, a zoning was formed, determined by the distribution of watered layers, lenses and areas in the subsurface space. Pore waters are represented by highly mineralized solutions, in which the arsenic content reaches 7.7 mg/l. The geoelectric parameters of the substance are consistent with its geochemical composition, namely, the level of mineralization of pore solutions. Geoelectric sections indicate the presence of leaks deeper than the protective layer, and the ingress of toxic solutions into groundwater. The calculation of the metals amount and metalloids in solid matter and pore water, showed the existence of a high risk of the spread of arsenic in mobile forms large amounts in the event of extreme weather conditions and the spread of the substance outside the storage facilities.
