The study involves extensive laboratory tests to determine the physical and chemical parameters of the Surma river water, the values of which were used to calculate the water quality index and health risk. These parameters were Dissolved Oxygen (DO), Biochemical Oxygen Demand. (BOD), Chemical Oxygen Demand (COD), Total Solids (TS), Ammonium Nitrate (AN) and pH. Water samples were collected at different points along the Surma river for both dry and wet seasons. Samples were analyzed for the above parameters and using the average dry and wet season values of these parameters, an expression of Water Quality Index (WQI) was developed. Moreover, risk has been calculated for the same by Hazard Quotient (HQ). The values of WQI were found to be 73.37 for dry season and 73.51 for wet season. HQ for Cu only was found to be 0.1788. The study concluded that the Surma river water was slightly polluted and no health risk was imminent at that time. |
