New Delhi: A recent report by the Central Pollution Control Board (CPCB), submitted to the National Green Tribunal (NGT), has confirmed that the Ganga’s water quality in Prayagraj during the Maha Kumbh 2025 was suitable for bathing. The study, based on twice-weekly water monitoring from January 12 onwards, found that the river met the Primary Water Quality Criteria for safe bathing.
Water Quality Within Permissible Limits
The report, dated February 28 and uploaded on the NGT website on March 7, highlighted that the Ganga and Yamuna rivers’ water quality at monitoring sites remained within the acceptable limits on auspicious bathing days. The CPCB analysis showed that the median faecal coliform (FC) level was 1,400 MPN/100 ml, which is below the permissible limit of 2,500 MPN/100 ml. Other key indicators, such as dissolved oxygen (DO) and biochemical oxygen demand (BOD), also met the required standards for safe bathing.
Data Variability Raises Concerns
Despite the overall positive findings, the report acknowledged significant variability in water quality data collected on different days and from different locations. This inconsistency was attributed to factors such as sewage drainage, tributary inflows, and changing weather conditions.
Interestingly, just days before releasing the report, the CPCB had informed the NGT that water at certain locations in Prayagraj did not meet bathing standards due to high faecal coliform levels. The discrepancy was mainly linked to untreated sewage from multiple drains entering the rivers, causing occasional spikes in pollution levels.
Government Efforts to Maintain Water Quality
In response to these concerns, the Uttar Pradesh government submitted an affidavit outlining the measures taken to maintain water quality during Maha Kumbh. The affidavit stated:
“In view of Mahakumbh-2025, it has been ensured that a sufficient stock of chemicals, including chlorine, FeCl3, poly, lime, and defoamer, shall be available at all the STPs (Sewage Treatment Plants), as well as additional manpower deployment considering the increased population during the festival.”
Authorities also emphasized their commitment to regular monitoring and sewage treatment to prevent contamination and maintain the river’s cleanliness.
A Positive Sign for Maha Kumbh Devotees
The CPCB report serves as a relief for millions of pilgrims participating in Maha Kumbh 2025, ensuring that the sacred dip in the Ganga remains a safe and spiritual experience. However, environmental activists urge continued vigilance and long-term solutions to ensure the sustained cleanliness of the Ganga beyond the festival period.
As the world’s largest religious gathering continues, efforts to balance tradition, environmental responsibility, and public health remain a key focus for authorities and stakeholders.
