The problem of water ecosystem pollution is increasing every year worldwide, and this issue has become even more urgent due to the full-scale military actions on the territory of Ukraine. Monitoring the condition of the Zaporizke (Dniprovske) reservoir is extremely important, as the deterioration of water quality and its sanitary condition can pose risks to both the population and the biota. The aim of the study was to analyze the physicochemical parameters of water in the central section of the Zaporizke (Dniprovske) reservoir, specifically near Monastyrskyi Island, and to assess its suitability for domestic, recreational, and fishery purposes. The research was conducted throughout 2024 near Monastyrskyi Island (Dnipro city). To determine the physicochemical parameters of the water, the stationary station "NAYADA-2" was used. The chemical composition parameters of the water were compared with the regulatory standards for domestic, recreational, and fishery purposes. The study found that most of the physicochemical parameters met the regulatory standards for domestic, recreational, and fishery purposes. However, in the summer months, an exceedance of the chemical oxygen demand (CODCr) and a decrease in dissolved oxygen concentration were observed, which is a seasonal phenomenon related to the increase in temperature. Additionally, in August, the maximum concentration of total suspended solids was recorded at 24.6 mg/dm³, which does not meet the regulatory standards for fishery purposes. In the autumn, an exceedance of the BOD5 (biochemical oxygen demand) values was recorded, which could indicate organic pollution of the water body. Comparing the obtained data with previous studies in 2023, no critical changes were found. According to the study results, the water in the research area met the regulatory standards for domestic, recreational, and fishery purposes for most of the parameters and provides a favorable environment for the existence and reproduction of hydrobionts.
