While Maha Kumbh Mela symbolizes spiritual renewal, it simultaneously raises critical environmental concerns, particularly regarding water quality. This field report from Prayagraj by Munjuluri UV Ramesh of Neo Science Hub, delves into the comprehensive water quality data collected during the Kumbh Mela, providing a scientific perspective on pollution levels and their implications for public health and river ecosystems.
Water Quality Monitoring: A Snapshot
The Central Pollution Control Board (CPCB) plays a pivotal role in monitoring the water quality of the Ganga and Yamuna rivers during the Kumbh Mela. Recent assessments, as reported in January 2025, have revealed varying levels of key water quality parameters across several key locations—Shringverpur Ghat, Lord Curzon Bridge, Sangam, and Deeha Ghat—signifying fluctuations in pollution levels throughout the rivers’ stretches.
Key Parameters Analyzed
1. pH Levels: Optimal pH for freshwater typically ranges from 6.5 to 8.5. Recent analyses in the Kumbh showed pH values between 7.34 and 8.85, which suggest generally acceptable conditions but highlight the need for ongoing monitoring to ensure stability.
2. Dissolved Oxygen (DO): Crucial for sustaining aquatic life, DO levels below the minimum desirable threshold of 5 mg/l indicate potential ecological stress. Reports documented DO levels as low as 2.2 mg/l, particularly in densely populated areas, raising alarms over aquatic health.
3. Biochemical Oxygen Demand (BOD): BOD levels serve as an indicator of organic pollution; values exceeding 3 mg/l are concerning. At some testing sites, BOD levels reached a staggering 28 mg/l, reflecting significant organic material decomposition and a direct impact on water quality.
4. Fecal Coliform Levels: As a benchmark for bathing safety, fecal coliform concentrations should remain at or below 2,500 MPN/100ml. Locations like Sangam and Deeha Ghat exhibited levels far exceeding this threshold, signalling severe pollution and posing health risks for millions of pilgrims.
The data consistently underscore a pressing need for effective pollution control measures and risk management strategies, particularly as the anticipated influx of visitors looms closer.
Implications for Public Health
The implications of compromised water quality during the Maha Kumbh Mela extend beyond the immediate enjoyment of this sacred event. Elevated levels of faecal coliform bacteria pose substantial health threats, increasing the likelihood of waterborne diseases such as gastroenteritis and respiratory infections among attendees. With contaminated water sources providing a pathway for pathogens, health authorities must prioritize immediate responses to safeguard public health.
The scientific analysis of water quality data from the Kumbh Mela reveals a complex interplay between spiritual practices and environmental health. The outcomes of such vigilance are essential not only for sacred gatherings but for the ecological legacy of the Ganga and Yamuna rivers.
