Over 55 tonnes of garbage and waste were removed from the Ganga by a 40-member team during its month-long expedition in the river, said its leader Everester Bachendri Pal.

The team left Jamshedpur on October 01.
The garbage and waste pulled out of the river were disposed of by respective municipalities of the seven towns the team reached, she said.
"We had a good experience in making aware hundreds of people, including school children, who joined us at every destination about the need for clean Ganga ," she said.
She advocated intense awareness campaign to clean the river and said the central government had already taken up several measures for the purpose.
The 40-member team, which included Everesters Premlata Agarwal, first Indian woman to climb all the seven summit of the world, Hemant Gupta, Binita Soren, favoured 'Shramdaan' (voluntary work) by the common people to make the river free of pollutants, she said.
