- Аннотация: Rocks and groundwater of karst areas are weakly protected from any pollution. The most common pollutants within them are oil hydrocarbons. Microbial populations of karst rocks and groundwater are able to degrade a large number of contaminants under the existing redox conditions, often used in biotechnological methods of remediation. The authors investigated oil polluted karst territories of the Perm region (Russian Federation) to develop methods of remediation. Two sites of karst rocks and groundwater with different redox conditions and impacted by oil and oil-products were studied. Aerobic hydrocarbon-oxidizing bacterial processes occured in the first site, and this paper describes the complex method of mechanical and microbiological cleaning to achieve complete oil removal. Anaerobic degradation of oil hydrocarbons during sulfate reduction process was detected in the second place. One of the products of this process, hydrogen sulfide, is very toxic to water fauna but readily oxidative in air. The authors recommend constructing special oxidizing and precipitating ponds to improve the environment.
