Abstract
Oil pollution of surface waters in the karst area was studied on the example of the Kama reservoir (Perm Region, Russia). The aim of this work was to identify areas of subaquatic discharge of groundwater contaminated with oil products and to identify the mechanism of pollution of the reservoir. A complex of hydrochemical and thermoresistivimetric studies was carried out and as a results abnormal zones and not a typical pattern of groundwater movement in the area were revealed. The complex of these methods makes it possible to assess the pollution of the water area associated with subaqueous discharging groundwater, outline the places of concentrated discharge, and optimize the hydrochemical testing network. At low financial costs and ease of implementation, the method is highly reliable of the results obtained, it allows us to understand the mechanism of oil pollution of the reservoir and to develop the optimal complex of protective structures. This method can be used to outline the discharge zones, which contain a wide variety of pollutants, the identification of which by geochemical methods at great depths and in large areas is not an easy task.
