ANALYSIS OF MICROBIAL LOAD IN ‘KALKHADI LAKE’, KHARBAV, (DIST : THANE), INDIAV.V. DALVIE , G.K. AMTE AND BELA NABER
Lakes and water bodies form vital eco-systems supporting livelihood, storing rainwater, providing recreation space with social, economic and aesthetic benefits. In the present study attempts are made to determine the microbiological parameters from water, soil and fish samples from Kalkhadi Lake, Kharbav in Bhiwandi, Dist: Thane, Maharashtra. The objective of the study is to assess the water and soil quality and its effect on aquatic life in the lake, as the lake is an important source of livelihood for the community around. Survey revealed that above lake though not detrimental is being used for farming/ irrigation and fishing purpose by communities nearby. Water, soil and fish samples collected from the above lake were studied. Various parameters studied were pH, DO, microbial load of fungi and bacteria including Enterobacteria from the lake water, soil and fish. The bacteriological analysis shows presence of Escherichia coli indicating sewage pollution. Sewage must be diverted from lakes to balance the flora and fauna in catchment area and remedial measures should be undertaken. The studies revealed in general that though the water is not potable it is suitable for aquaculture and that a blend of improved traditional method with cage culture of ornamental fish and propagation of aquatic ornamental plants with pearl culture being experimented will enhance sustainability of aquaculture practices leaving scope for further experimentation.
