This study explores the development of the geochemical composition of surface waters in the Nura River basin, influenced by human activities. Water samples were analyzed at the accredited "Kazhydromet" RSE laboratory in Karaganda city to measure pollutant concentrations. The results were compared to phonic values, showing the pollution trends in the Nura River basin. The main pollution sources are insufficiently treated discharges from industries in Karaganda-Temirtau industrial area, including key facilities such as "Karmed" LLP, "Bassel Group LLS", "Temirtau Electrometallurgical Plant" JSC, and other industrial operations, which release such contaminants as suspended solids, phenols, and heavy metals into the environment. The analysis indicates that anthropogenic activities have a significant impact on water quality, emphasizing the need for improved operation of treatment facilities to maintain the ecological balance of the Nura river and its surrounding water bodies
