Dynamics of changes in water quality indicators of the Dnipro River within the boundaries of the city of Kyiv

As a result of the socio-economic development of society, meeting the needs of the population with high-quality drinking water remains an open problem in Ukraine. The uneven provision of the territory of Ukraine with water bodies, improper treatment of wastewater before discharge into water bodies, as well as the conduct of active hostilities negatively affect the state of surface and underground water bodies. As a result, we have a decrease in the number of sources for water supply, a decrease in the percentage of centralized water supply in small settlements. In the future, this may lead to an acute shortage of drinking water in the country. For Kyiv, the main source of water supply is the Dnipro River. In this work, a study was conducted of the concentration indicators of chemicals in the Dnipro River in the period from 01.01.2024 to 30.11.2024, depending on the hydro solution. An assessment of water quality was carried out using the water pollution index (WPI) and generalized complex hydrochemical indicators for the period from 2017 to 2023. The results of the assessment of the self-purification capacity coefficient of the Dnipro River within the city of Kyiv were also studied.
