Where Ganga meets the Bay of Pollution

An exponential increase in the number of pilgrims coming to the Ganga Sagar Mela, which takes place at the Sagar Island every year during Makar Sankranti, has been responsible for the worsening water pollution, prompting scientists to raise serious concerns about the likely outbreak of several diseases.

The number of pilgrims descending on the Sagar Island to take a dip at the place where the Ganga meets the Bay of Bengal, has risen from 2 lakh in 1990 to 20 lakh in 2018.

“A health survey was conducted with the local people… it found that diseases like cholera, dysentery, and skin disease were predominant in the post-Ganga Sagar Mela period,” observed a paper titled ‘Pollution and its consequences at Ganga Sagar mass bathing in India’, published recently in the journal Environment, Development and Sustainability.

The study noted a sharp deterioration in water quality parameters between the pre-mela and post-mela period. For instance, the concentration of faecal coliform bacteria, which was 22 MPN (most probable number) in 100 ml of water two weeks before the mela, was found to be 9,963 MPN two weeks after the mela.
