RESULTS OF OBSERVATIONS ON THE INDICATORS OF THE DNIPRO WATER, WHICH INTENSIFY ITS "BLOOMING", AND RECOMMENDATIONS OR PREVENTIVE MEASURES

Abstract

Objective. Analysis of the results of systematic observations of the indicators that characterize the "blooming" of the water of the Dnieper River in space-time aspect, and providing recommendations for its prevention. Materials and methods. To assess the water quality of the Dnieper River, an array of data from the State Agency of Water Resources "Dnieper Basin Water Resources Management" (2015–2017, 906 samples), the State Water Cadastre (2016), "UNHC Ministry of Health" on the state of water in Ukraine (1992–1994), “National Report on Drinking Water Quality and the State of Drinking Water Supply in Ukraine” (2005–2016), Lithuanian Waste Management Regulation (2006), Council Directive 91/271/ЄEC. Methods were used for data processing: analytical, statistical, correlation, mathematical modeling. Results and conclusions. A high content of phosphates and organic substances in the water of the Dnipro river in the spatial-and-temporal section is demonstrated, which indicates a natural and anthropogenic contamination and will lead to the potential problems with the contamination of tap drinking water made of the Dnipro water. It is proved that one of the priority tasks today should be to reduce the content of organic matter, phosphorus and nitrogen in surface waters, which can be achieved by establishing coastal strips and provided by law, as well as the use of modern technologies for industrial and domestic wastewater treatment, this requires regulation. Further harmonization of Ukraine’s water legislation with European legislation will help prevent water-related morbidity.
