A STUDY OF PHYSICO-CHEMICAL PARAMETERS OF MITHI RIVER WATER IN MUMBAI METROPOLIS
Water plays a very important role in sustaining life. The quality of water acts as a barometer of the environmental health and well being of the human society. In the last 3 to 4 centuries, urbanization and industrialization have progressed affecting water bodies, which are being generally used for discharging domestic and industrial wastes. The river water pollution has an adverse effect on the environmental health and hygiene of people in surrounding areas of the river. It also affects the river water ecosystem.
In order to assess the quality of Mithi River water, four sampling stations along the course of the Mithi River were selected. The sampling points were selected in such a manner so as to ensure substantial pollution, considering the residential units and commercial activities near the sampling points. The investigation has been carried out throughout the year i.e. from October 2011 to September 2012. The physico-chemical parameters viz., pH, E.C., D.O., B.O.D., C.O.D., total hardness, total alkalinity, chlorides, nitrates and phosphates were analysed. It has been observed that some of the parameters substantially exceeded the limits when compared with the standards set by BIS and CPCB. The River water was therefore heavily polluted with number of organic and inorganic pollutants. A mechanism for the continuous monitoring of the river water and efforts to control discharge of waste in the Mithi River are required.
