Abstract :

Water is an elixir of life that governs the evolution and functions of the universe on earth hence water is "the mother of all living world". Industrial sewage and municipal wastes that are discharged to water reservoirs, affect the physicochemical quality of water making them unfit for use of livestock and other organisms. The present investigation has been carried out to assess the physicochemical and microbial profile of pond water samples in Sundarakkottai village, Mannargudi. The results of this study indicated that some of the water quality parameters are high exceeding the permissible limits of World Health Organization (WHO). The bacteriological analysis revealed the presence of bacteria such as Escherichia coli, Staphylococcus aureus, Klebsella pneumoniae, Pseudomonas aeroginousa, Proteus vulgaris, Bacillus subtilis, Vibrio cholerae, Clostridium difficile, Shigella dysentrine and Salmonella typhimurium and fungi such as A. fumigatus, A. niger, P. brevicompactum, Fusarium sp., and A. flavus. The results clearly indicated that the pond water samples are not satisfying the normal requirement for various applications and it is unsafe for humans without treatment.
