Yes, you read that correctly. Bacteriophage bacteria can be found in the holy river Ganga. It infects and kills other harmful bacteria that have infiltrated the river. That is why, even if stored for an extended period of time, river Ganga water does not spoil. According to D.S. Bhargava, an environmental engineer at the University of Roorkee, the Ganga is the only river in the world that decomposes organic wastes 15 to 20 times faster than any other river.
