Abstract

We propose a method of hydrogeoecological prospecting for anthropogenic contamination with emulsified petroleum products of groundwater in the intrusive massifs of the Eastern Urals hydrogeological folded region. The method is the basis for designing the groundwater treatment with hydrogeodynamic traps. In the process of mapping, we find the indications for prospecting. We propose engineering solutions for safe arrangement of petroleum product traps adapted to heterogeneity geofiltration and capacitive properties of the intrusive massifs. We give recommendations concerning development of the technological schedules of oil mining and utilization of the disposed groundwater. We illustrate the granitoid massifs groundwater treatment in terms of purification from pollution with suspended mixtures of benzene, kerosene and diesel by examples of providing industrial and environmental security for oil storage facilities in the Middle Urals.
