WATER POLLUTION ANALYSIS OF MUTHA RIVER ACROSS PUNE CITY USING BOD AS PRIMARY PARAMETERP. S. ABHYANKAR, S.V. AMBADE AND R.B. PATWARDHAN
The five rivers in Pune city are, Mula, Mutha, Pawana, Ram and Dev River. Mutha river originates, in the Western Ghats at a village named Vegare, about 45 km to the west of Pune city, India. Mutha River has two tributaries, Ambi and Moshi. There are two dams on Mutha River, at Temghar and at Khadakwasla. Increasing urbanization coupled with industrialization during the past few decades are depleting aquatic ecosystems. With the rapid increase in the population of the city and the need to meet the increasing demands of human and industrial consumption, the available water resources of the city are getting depleted and the water quality has deteriorated. Mutha River is polluted due to the discharge of untreated sewage and industrial effluents. Present study was undertaken to study the level of pollution in Mutha River of Pune city. Water samples were collected from 20 different locations on Mutha river across the city. Various physico-chemical parameters were checked. Biochemical Oxygen Demand (BOD) is an important water quality parameter as it provides an index to assess the effect that the discharged waste water will have on the receiving environment. A comparative account of BOD values at various locations was taken to establish the pollution level of Mutha River in Pune city.
