Determination of basin’s ability to self-purification allows prospective forecasting of its ecosystem condition, which is important in solving economic problems. To determine the ability of the reservoir to self-purification the authors
use Eh-metrics method, based on the assessment of the oxidation-reduction potential distribution in a layer of sediment, which is an integral parameter comprehensively characterizing the ability of water reservoir natural self-purification in general. The presented analysis of methodological inaccuracies in determining the selfpurification
ability of the reservoir applying Eh-metrics method allows us to conclude that for their adjustment it is necessary to obtain information not only about the distribution of the oxidation-reduction potential in a layer of sediment, but also about the temperature, thickness of the protective layer and about the inclination angle of the measuring Eh-electrode sensor implantation from the vertical line.
