Gomti River oxygen levels dangerously low, threatens aquatic life

Lucknow: The Gomti River is facing a serious environmental crisis as its oxygen levels have fallen to a dangerously low point. A recent water quality report shows that the Dissolved Oxygen (DO) level near Kudiya ghat is just 1.5 mg/litre, while the Biochemical Oxygen Demand (BOD) has risen to 18 mg/litre. These tests were conducted by Babasaheb Bhimrao Ambedkar University's Environmental Science department. Experts say that a DO level of at least 5 mg/litre is necessary to support aquatic life. When oxygen levels drop below this, fish and other aquatic species struggle to survive. The high BOD indicates significant pollution, primarily from sewage and industrial waste. Professor Venkatesh Dutta highlighted the issue of water hyacinth growth, which is covering a 500-meter stretch of the river. This overgrowth is linked to rising temperatures and untreated waste entering the river. Professor Dhruv Sen Singh from Lucknow University added that the pollution and reduced water flow lead to less sunlight reaching the water, further decreasing oxygen levels. These conditions threaten the natural ecosystem of the Gomti River. Despite efforts for conservation, issues like untreated sewage and encroachments continue to harm the river. Experts stress the need for stricter pollution control, better waste management, and restoration efforts to revive the river's health. Meanwhile, officials from the Lucknow Municipal Corporation report that cleanup activities for the water hyacinth are ongoing, with plans to clear the weeds within a week.
