Water Quality Insights from Kumbh Mela: CPCB’s Findings and Future Preparations
The CPCB’s report stated that the Ganga’s water quality during the Maha Kumbh was suitable for bathing, despite highlighting variability in data across sampling times and locations. The report reported acceptable levels of faecal coliform, dissolved oxygen, and biochemical oxygen demand, although prior concerns were raised regarding pollution. In response, Uttar Pradesh has outlined preparations for Mahakumbh-2025 to ensure better water quality management.
The Central Pollution Control Board (CPCB) report to the National Green Tribunal (NGT) on March 9 indicated that the Ganga’s water quality during the Maha Kumbh in Prayagraj was deemed suitable for bathing. However, the CPCB noted significant “variability in data” regarding samples from the same locations taken on different days. This was particularly relevant during crucial bathing periods of the Maha Kumbh event in 2025.
Monitoring commenced on January 12, with water quality assessed biweekly at five Ganga sites and two Yamuna sites. Factors influencing data variability included sewage discharges, weather patterns, and tributary inflows. The variability necessitated statistical analysis to accurately represent the overall water quality, as the same sites on varying dates could produce inconsistent results.
The report highlighted a median level of faecal coliform at 1,400 MPN/100 ml, which aligns with the acceptable limit of 2,500 MPN/100 ml. Moreover, the dissolved oxygen level recorded was 8.7 mg/L—above the minimum requirement of 5 mg/L—and the biochemical oxygen demand registered at 2.56 mg/L, under the permissible level of 3 mg/L. Despite this, earlier information indicated that the water quality at various Prayagraj sites did not meet bathing criteria due to high faecal coliform levels.
Concerns about pollution from untreated sewage entering the Ganga and Yamuna prompted discussions before the NGT. In response, the Uttar Pradesh authorities submitted an affidavit outlining the steps taken to maintain water quality for Mahakumbh-2025, which included ensuring an adequate supply of treatment chemicals and increasing manpower at sewage treatment plants during the event.

The CPCB’s report on the Ganga’s water quality during the Maha Kumbh reveals a complex picture of suitability for bathing interspersed with variability due to pollution factors. While statistical data shows compliance with certain water quality metrics, ongoing issues with faecal coliform and concerns over untreated sewage remain significant. Authorities are actively preparing for future events to enhance water quality management.
