The Burhi Gandak River, a significant tributary of the Ganga River and vital water source in Bihar, India, is facing critical quality degradation due to rapid population growth, urbanization, industrial activities. This study conducts detailed assessment river, focusing on effects these anthropogenic factors across different locations, seasons, zones. Water samples were collected analyzed for key parameters, including pH, total dissolved solids (TDSs), hardness (TH), biological oxygen demand (BOD), (DO). results indicate spatial temporal variations, with deteriorating notably areas like Samastipur Khagaria, where urban activities are more concentrated. For instance, BOD levels increased from 7.5 mg/L 9.5 mg/l as river flows through Samastipur, signaling decline quality. Additionally, sugar mills located along contribute higher pollution during operational months, especially Lauria Sugauli. Seasonal analysis shows that lean season experiences highest degradation, while monsoon floods increase suspended sediment inflow. These findings emphasize urgent need improved regulation discharge waste management protect livelihoods dependent it.
