Latest research has pointed out that the level of pollution in the holy river has reached an alarming proportion and the Ganges water is unfit not only for drinking and bathing but also for agricultural purposes.

A joint team of army and air force officers has completed its journey from Allahabad to Patna on the water route. Members of the team said they were shocked at the filthy condition of the riverbanks, the garbage dumping and the flow of untreated sewage water into the Ganges.

'We came across dozens of half-burnt bodies and corpses floating in the river. We also came across animal carcasses and heaps of polythene bags,' a team member said.

According to an estimate of the environmental science department of AN College, Patna, during the river's 2,510-km-long journey from Gaumukh to the Bay of Bengal, nearly a billion litres of untreated sewage gets disposed of into the river.

In Patna, the Ganges has shifted its natural course as a result of pollution.

Over Rs.8 billion has been spent in the last three years to clean up many Indian rivers, but major ones like the Ganges and the Yamuna continue to be dirty. Most of the money was spent on cleaning the drains that empty into the rivers by putting in sewage treatment plants (STPs) and sanitation facilities.

Last year, the committee expressed concern about the state of the high-profile Ganga (Ganges) Action Plan (GAP) meant to clean India's longest and most famous river.
