ABSTRACT:

Water from Esil River was sampled in March-November 2013 and studied. Hydrochemical samples were used to determine chemical pollutants and water quality class. Hydrobiological water samples were used to define: 1) total bacterialcount, share of heterotrophic bacteria, bacterial production; 2) qualitative and quantitative characteristics of phytoplankton: species diversity, primary daily productivity. The outcomes were compared by their seasonal dynamics.
