Assessment of Water Quality: A Case Study of River Yamuna

Abstract

: According to the Hindu mythology, river Yamuna is considered as one of the most sacred rivers after the Ganges. In this study water quality of the river Yamuna was assessed at four different sampling locations during the months of May to August 2014. Physico-chemical parameters like pH, EC, turbidity, TDS, DO, BOD, COD, Cl - and SO42- were analyzed and the observed results were compared with the standard limits of BIS and WHO. The mean pH, EC, turbidity, TDS, DO, BOD, COD, Cl - and SO 42- values at the four sampling sites were observed in the range of 7.81-8.00, 1046.5-1195.3 µS/cm, 27.0-37.3 NTU, 856.5-936.0 mg/l, 4.5-5.2 mg/l, 19.3-25.8 mg/l, 58.0-85.0 mg/l, 242.5-267.0 mg/l and 97.75-114.0 mg/l respectively. The results on the water quality parameters of Yamuna river indicate that the river is not safe for domestic purposes.
