Dams and reservoirs are vital components of public infrastructure, providing numerous benefits at both local and national levels. Their primary purposes include flood control, irrigation, hydroelectric power generation, drinking water supply, industrial water supply, and support for tourism and recreational activities. However, the manipulation of natural water flows combined with intensive rainfall has led to significant degradation of physicochemical water quality. Freshwater quality is declining due to rapid industrialization, growing populations, and increasing global pressures, all exacerbated by poor management, resulting in severe environmental degradation. The status of water quality is dynamic and is typically assessed through approximations, deviations, or the degradation of physicochemical parameters. This paper primarily focuses on monitoring the water quality of the Hirakud Dam reservoir. The Dam is situated near numerous upstream industries, increasing the likelihood of water contamination. Periodic testing of the reservoir's water for various chemical contaminants has been conducted, along with studies on their effects on concrete. This study contributes to assessing and predicting water quality dynamics, providing valuable insights into the reservoir’s chemical contamination. By implementing the control strategies and continuous monitoring in a coordinated and integrated manner, it is possible to reduce the adverse impacts of anthropogenic activities on water quality and safeguard the health and integrity of aquatic ecosystems for future generations.
