Abstract: This study focuses on the persistent need for safe drinking water by conducting a seasonal assessment of the Asan River, a tributary of the Yamuna River in Dehradun, Uttarakhand, India. During the monsoon season (July-August) of 2024, five water samples were collected from various locations along a 40 km stretch of the Asan River. The research evaluated thirty physico-chemical and biological parameters, including temperature, pH, electrical conductivity (EC), dissolved oxygen (DO), biochemical oxygen demand (BOD), chemical oxygen demand (COD), total suspended solids (TSS), total dissolved solids (TDS), turbidity, and ion concentrations, along with bacterial counts. The study shows the negative correlation coefficient of -0.811 between temperature and biochemical oxygen demand (BOD), suggesting that as temperature increases, BOD tends to decrease. The findings demonstrate the relations between pH and major water quality indicators. The findings emphasize the urgent need for continuous monitoring and effective management of river ecosystems to ensure water quality and public health protection amidst increasing pollution challenges.
