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.

Comparison of climatically controlled phases of higher rainfall and flood frequency with the anthropogenic phases of effective soil erosion documents various overlappings and superpositions. The wetter phase with high frequency of extreme events leads to the transformation of relief, well expressed in the ecotonal zones and in the high mountains. Increased human activity controls an accelerated soil erosion, overbank deposition and tendency to breading. The most distinct changes, leading to the passing of thresholds and transformation of slopes and valley floors are connected with the coincidence of wetter climate and high anthropogenic pressure. Those phases were recognized in Central Europe during the middle Neolithic period, the early phase of the Roman period, the 10th-11th century and the Little Ice Age.
