Abstract

Ust-Ilim reservoir and the bay of the Vikhoreva River on microbiological parameters were investigated. A comparative analysis of the results obtained with these of 1980-1990 years was carrying out. The total number of microorganisms ranged from 0.9 to 6 million cells/ml, remaining at the level of previous years. The number of saprophytic bacteria decreased in the order. High values of saprophytic bacteria identified in the waters of the Vikhoreva River (5240 CFU/ml) and backwater bay Vikhoreva (10700 CFU/ml). The maximum values of coliforms were found in backwater bay r. Vikhoreva (11333 CFU/l). Number of cellulolytic microorganisms has decreased by three orders of magnitude and amounted to 1-9 CFU/ml. Sulfate-reducing bacteria were found only in the bay of r. Vikhoreva. Water of bay of r. Vikhoreva and adjacent waters of the Ust-Ilim reservoir on the microbiological data comply with SanPiN 2.1.5-980-00 and can be used only for recreational purposes.
