Abstract

Quality assessment and analysis of a current state of natural waters, especially when it comes to reservoir waters, is a very important stage in the organization of safe drinking water supply for human life and health. The purpose of this study is to assess a current ecological state of the Kakhovka reservoir in the Dnipropetrovsk region for the period 2016–2018. The object of the study is the natural waters of the reservoir. The subject of the study is a current ecological state of the waters of the Kakhovka reservoirs within the Dnipropetrovsk region. Research methods are based on comparative-geographical, statistical, zoning and other research methods. In addition the work used: A graphic method for an integrated assessment of a surface water quality; A method for assessing the water quality in the water bodies by hydrochemical parameters. According to the results of the study of a current state of the Kakhovka reservoir waters within the Dnipropetrovsk region for the period 2016–2018, it was found that among the nine water quality indicators the priority indicators are: chemical oxygen consumption (COC) and biological complete oxygen consumption (BOcC). In most cases, these indicators were observed to exceed the limited permissible concentrations (LPC). High values of the COC indicator are a consequence of this water pollution with sewage; and high values of the BOcC index indicate a significant organic content that decomposes in the water. As a result of the analysis of the dynamics of changes in the total indicators of the LPC multiplicity, a stable improvement in the water conditions of the Kakhovka reservoir occurs in section № 4, and for other observation points an improvement in the water condition is observed in 2017 compared to 2016, and in 2018 compared to 2017 there is a deterioration in the state of natural waters.
