Аннотация: Karst rocks are well developed on the Earth and occupy its vast territories. Groundwater of karst areas is weakly protected from oil pollution, and the remediation of contaminated groundwater is difficult and costly. The main tasks of our study were the development of the strategy of remediation of oil-polluted groundwater at karst region of the Polaznenskoe oil deposit (the Western Urals, Russian Federation), where an oil lens (thickness up to 2–3 m) was formed within karst rocks on the surface of water table and became a source of pollution of the Kama river reservoir. Two-staged strategy of remediation was proposed and used. The first stage included the “mechanical” technique of remediation, the second one – biochemical destruction of water-dissolved oil using oil-degrading bacterial preparation. About 12 m3 of oil-products was pumped out the oil lens, and approx. fourfold decrease of n-alkanes within oil layer was achieved after 3 months of the biochemical remediation.
