The analysis of anthropogenic factors influencing the state of natural water is carried out in the work. The need for a detailed study of the impact of urban areas on river water quality is noted. The study of the state of one of the main rivers of Poltava region in the area of about 100 km during the winter-spring period on the parameter of mineralization. The influence of individual settlements on the water status of the Vorskla River is considered. There was a gradual increase in river water pollution in the studied area and an increase in mineralization from 660 to 820 mg/l (February) and from 500 to 580 mg/l (April) (Sr = 2%). It was found that the greatest anthropogenic impact on the state of the Vorskla River is in the area of Poltava - Novi Sanzhary. The influence of surface runoff on changes in surface and groundwater quality of Poltava region is shown.

The paper considers the impact of urbanized areas on the state of water bodies. The impact of various types of anthropogenic activities on water bodies located in cities was shown. In towns, there is worse water resource management than in large cities and the necessity of conducting more detailed research. Using the method of direct conductometry, a spatio-temporal study of the ecological state of water bodies located within the detached objects of the urbanized territory of the Ukraine was carried out using the example of Popasna town. It was shown that fluctuations in the electrical conductivity of these bodies are mainly due to the influence of surface runoff. It was found that in all studied ponds there was a significant drop in the electrical conductivity of water in March 2021, followed by an increase and stabilization in April and May 2021, the characteristic values of electrical conductivity range from 200 to 2900 μS, the relative standard deviation did not exceed 1.5%. The necessity of conducting further, more detailed study of the features of the influence of surface runoff on the water condition in the studied ponds was shown for the purpose of rational management of these water bodies.
