FEATURES OF OIL POLLUTION OF UNDERGROUND AND SURFACE WATERS IN THE KARST REGIONS OF THE SOUTH OF THE PERM TERRITORY
The development of oil fields in the Perm Region is associated with the pollution of soils, ground, underground and surface waters. The causes of contamination are leaks of petroleum products during the operation of technological equipment and as a result of insufficient insulation of the fluid barrier over the oil deposit. The rate of migration of oil pollution depends on natural conditions, and the reservoir properties of soils and rocks are of particular importance. In karst areas, the migration of oil pollution occurs through karst reservoirs (karst cracks, caverns, cavernous cavities). At the same time, from the primary source, oil pollution quickly enters the aquifers and manifests itself in the places of their discharge in the horizontal and siphon zones.
