The scientific article examines the results of water quality studies in order to identify the ecological state and geochemical features of the Barbastau River. The study was conducted in the field in the fall of 2024 and in the spring of 2025, the camera period was conducted in the testing laboratory of ecology and biogeochemistry of the Utemisov West Kazakhstan University. Hydrological, geomorphological, and physico-chemical studies of water samples were conducted to assess the ecological and chemical state of the Barbastau River. During the study, the main ions and trace elements contained in the river water were identified. For a complete assessment of the ecological state of the water, the data obtained were processed in accordance with GOST methods. Based on the results obtained, a table and diagram have been compiled, the results have been summarized and the ecological state has been determined. The final results will make it possible to determine the necessary measures in the future to improve the ecological condition of the Barbastau River.
