dc.description.abstractAn assessment of the surface water state resources was provided, which included the analysis of the components of the salt composition, namely chlorides and sulfates. The trophic-saprobiological (ecological-sanitary) index was determined taking into account the absolute values of indicators: suspended substances, pH, phosphates, dissolved oxygen, BOD5. To determine the index of specific indicators of toxic action, the absolute values of the components were used: copper, zinc, oil products, etc. It was determined that the category of water quality according to the components of the salt composition in the pre-war period was 6.1, which is less than in 2022 (6.5); according to tropho-saprobiological indicators (environmental and sanitary) - the pre-war period is 4.3, which is less compared to 2022 (5.0); according to specific indicators - in the pre-war period it is less and is 4.7 compared to 2022, when this index was 5.0. All defined surface water quality classes correspond to the degree of pollution "dirty" or "very dirty" and the state "poor" or "very poor". During the studied period, there is a steady trend towards a gradual increase in hardness, dry residue, sulfates, and chlorides in surface water. The level of pH, BOD5, dissolved oxygen fluctuates within the normal range with minor deviations.
