Impact of IDPL effluent on water quality of river Ganga at Shyampur Khadir, Rishikesh (Uttaranchal)

Abstract

Present paper deals with the impact of IDPL effluent on water quality of river Ganga at Shyampur Khadir, Rishikesh. A significant deterioration of water quality of Ganga was recorded at Shyampur Khadir. Water quality of river Ganga at Pashulok Barrage (1.5 Km. before discharge of IDPL effluent) was better in term of various physicochemical characteristics, valued mg/It, chloride- 5.6, DO- 8.8, BOD- 7.14 and COD- 20.95 was observed . Bacterial load of water in term of MPN and SPC was found 11.6x102/100 ml and 102x103/ ml respectively. But a high degree of deterioration of water quality was recorded at Shyampur Khadir located about 1.5 Km. away from discharge point in down stream of the river Various parameters were found highly enhanced i.e. Hardness- 137.8, cholride- 14.3, BOD- 58.8, COD-162.45, MPN -64x102 and SPC- 290x 103. Main cause of deterioration of water quality of Ganga at Shyampur Khadir was found due to the discharge of IDPL effluent which was highly polluted as evident by low level of DO-2.8 and high degree of BOD- 181, COD- 261.8 mg/l and MPN- 209x102 and SPC- 380x 103.
