Bengal's Rivers Dying: 17 Critically Polluted
27 Sep
Summary
- Seventeen rivers in Bengal, including Adi Ganga, are critically polluted.
- High organic pollution is evident in Mahananda, Bidyadhari, and Churni.
- Ecological flow and floodplains are vital for river revival, not just sewage treatment.
Bengal's rivers are facing a severe crisis, with 17 identified as critically polluted, including the Adi Ganga in Kolkata. Assessments reveal alarming pollution levels, particularly organic pollutants, in waterways like the Mahananda, Bidyadhari, and Churni.
Water quality tests on the Adi Ganga showed high biochemical oxygen demand and dangerously low dissolved oxygen, impacting aquatic life. Experts warn that continuous sewage discharge and urban pressure are diminishing the rivers' ecological character, turning them into mere wastewater channels.
River scientists stress that restoring these vital ecosystems requires a holistic approach. Simply treating sewage is insufficient; preserving ecological flow, protecting floodplains, and preventing encroachment are crucial for their long-term health and revival.
