Perceiving bacteria as dangerous is now turning towards greater awareness of the microbial world
as a fundamental element of life. The present research work has been carried out to analyze the
physico-chemical characteristics of Yamuna river water and to reduce the load BOD, COD, hardness,
alkalinity, acidity, dissolved solids, suspended solids, total solids by the process of bioremediation using
bacterial consortium. The bacterial consortium treated water sample showed a sharp reduction in BOD
i.e. 89% and 84% in COD. The result of the study indicates that Effective bacterial consortium helps in
the reduction of water impurities.
