ECOLOGICAL AND HYGIENIC ASSESSMENT OF THE STATE OF WATER SUPPLY OF THE POPULATION OF NIKOPOL OF DNIPROPETROVSK REGION FOR 2019–2024

Abstract

Topicality. After the Kakhovka hydroelectric power station in Nikopol (Dnipropetrovsk region), thecentralized water supply of drinking water ceased, which forced the search for alternative sources of water, including the use of wells. The analysis of literature data showed the limited information on the water supply of this city for 2019–2024.The purpose of the work is ecological and hygienic assessment of the state of water supply of the population ofNikopol of Dnipropetrovsk region for 2019–2024.Methods of research sanitary-hygienic, bibliometric, analytical.Results of the study. It is shown that water in the sections of the Kakhovka reservoir water intake in 2019 – the first half of 2023 was low-mineralized, moderately rigid, neutral. The inconsistency of water quality is established by the normative requirements for HSC, color, turbidity, permanganate oxidation, CSK, nitrite, copper, manganese and zinc nitrogen content. Water drinking from the centralized water supply system did not meet the regulatory requirements forcolor, turbidity, permanganate oxidation, chloroform, iron. In water from decentralized sources there were exceeding the standards for turbidity, color, taste, total rigidity, dry residue, content of sulfates, chlorides, iron. Monitoring of physicochemical indicators of water quality of non-centralized water supply in 2023– 2024 showed significant deviationsfrom the standards for artesian water, which the population is forced to use as drinking, by dry residue, rigidity, sulfates,chlorides, ammonium. The water of the reservoirs did not meet the regulatory requirements for the indicators of HCC,dry residue, sulfates, chlorides.Conclusions. It is recognized as necessary purification of artesian water in Nikopol by the method of reverse osmosisand the restoration of the system of centralized economic and drinking water supply.
