Keywords: the Seim River, automated software package, operational observations, polluted runoff, river flow quality certificate, flow quality dynamics.

Water quality is currently being evaluated regardless of the amount of water flow. Therefore, for the water industry, it is especially important to obtain a unified assessment of the quantity and quality of river water flow. Using the automated software package “Assessment of Polluted and Clean Runoff Indicators” developed at the State Hydrological Institute, it became possible to jointly process large volumes of standard hydrochemical and hydrological observation data at the posts. The first part of automated software package allows you to divide the volume of river flow by a single ingredient into pure when its concentration in the effluent does not exceed the maximum permissible concentrations (MPC), and into polluted when it is higher than the MPC. The main indicator of the quality of river water runoff in this method is the relative volume of runoff contaminated with a single ingredient. In the second part of automated software package, the annual volume of river flow is divided into partial volumes of various durations that differ in the composition of the complex of pollutants, and their degree of pollution is estimated by classes in accordance with ANON (2002) 52.24.643-20021. The estimates obtained are presented as a “flow quality certificate”. Based on the data on water quality monitoring of the Department of Hydrometeorological Service of the Central Black Soil Regions, using the automated software package, the quality of runoff for single chemicals and their complexes was estimated in the border hydrochemical observation point of the Seim River – Tetkino village. Observation period is from 1993 to 2013.
