Abstract
The paper describes the analysis of the microbiological specification and hydrochemical characteristics of the UGS facility located in the aquifer of the Moscow hydrogeological basin. A low abundance of aerobic organotrophic bacteria and anaerobic fermentative, denitrifying and sulfate-reducing bacteria in samples of formation water from UGS waters was shown. A high representation of bacteria of the genus Marinobacter, corresponding to the marine genesis of stratal waters, was noted. This testifies to the insignificant anthropogenic impact on the geological environment of the long-term operation of the Gdov horizon and the ecological reliability of the operating technologies used. Microbiological monitoring and zoning of the UGS territory according to the prevalence of the most typical microbiological communities will contribute to quality control during the operation of the UGS facility.
