The  Central Pollution Control Board (CPCB) has found alarming levels of faecal coliform in water samples sourced from several locations along the Ganga. The permissible limit for faecal coliform, a key indicator of sewage contamination, is 2,500 units per 100 ml. However, water samples from the Ganga exceeded these permissible limits.

The most alarming increase was observed before Shashtri Bridge, where faecal coliform skyrocketed from <1.8 to 11,000 MPN/100ml in less than a month. Similarly, at Sangam, the contamination jumped from 2,000 to 7,900 MPN/100ml, making it one of the most polluted spots during the Mahakumbh ritual baths.

Following these shocking revelations, the National Green Tribunal (NGT) reportedly took note of the UP Pollution Control Board’s (UPPCB) report, which lacked adequate explanation regarding the contamination spike. 

In response, the tribunal mandated that the Member Secretary of UPPCB and concerned state authorities appear virtually at the next hearing on Wednesday.

The NGT stated, “Even upon reviewing the documents enclosed with the covering letter dated January 28, 2025, it is reflected that high levels of faecal and total coliform have been found at various locations.” Authorities have been granted one day to examine the findings and submit a response.

Public health risk for devotees

With millions of pilgrims expected to continue participating in Mahakumbh, health experts are warning of increased risks of waterborne diseases due to the high bacterial contamination.

The presence of faecal coliform at these levels indicates sewage intrusion, which can lead to infections, gastrointestinal illnesses, and other health hazards.
