The problems of deterioration of the ecological state of surface sources of drinking water supply especially concern water reservoirs since they are created for accumulation of water reserves. Biochemical oxygen demand and dissolved oxygen are integral indicators that characterize ecological state of a water body on the whole. Based on retrospective observational data for 2010–2014, the authors analyzed dynamics of indicators of BOD and of dissolved oxygen in the Chervonooskil reservoir (Ukraine). The tendencies towards improving oxygen regime of the reservoir were detected: an increase in concentration of dissolved oxygen and a decrease in BOD by average annual indicators. This is explained by a decrease in anthropogenic load on the basin of the water body due to economic decline, which is a consequence of unfavorable political situation in the country. Authors determined coefficients of biochemical oxidation of organic substances of the Streeter-Phelps model for the water reservoir. Given the influence of temperature on oxygen solubility and on the rate of biochemical processes, calculation of parameters k 1 and k 2 was performed for each month of the year. Correlation coefficient between the modeled and empirical values of biochemical oxygen demand is 0.86, which can be considered acceptable for such research

The current poor state of water bodies testifies to the fact that the problems of water protection from pollution and depletion have not been solved and even significantly aggravated, especially in recent years. We have studied the quality of water and the ecological state of surface sources of drinking water supply in Kharkiv region and made a retrospective analysis of the chemical composition of the waste water that was released into the Siversky Donets by the Izyum Municipal Industrial Water Supply and Sewerage Company from 2008 to 2014. We have revealed the sustainable trends of worsening efficiency of wastewater treatment plants in the sanitation system of Izyum, which has, consequently, led to a significant deterioration in water quality and ecological state of the Siversky Donets that is the source of drinking water for settlements of three regions of Ukraine: Kharkiv, Donetsk, and Luhansk. We have suggested the basic ways to improve the water quality in the Siversky Donets and the ecological state of the entire region, which include: (1) a major reconstruction of sewage treatment plants in Izyum in order to improve the ecological state of the Siversky Donets basin and achieve the required quality of the surface water sources as well as (2) provision of a system of the state continuous monitoring of surface water in the Siversky Donets basins, within Kharkiv, Donetsk and Luhansk regions, to promptly identify the polluting enterprises, institutions and organizations and timely use the leverage provided by the current legislation of Ukraine.
