High ammonia levels in Yamuna threaten Delhi's water supply

Ammonia levels in the Yamuna River remain high, reaching around 5 parts per million for four consecutive days. This has led to a reduction in drinking water production at the Wazirabad water treatment plant, which is currently operating at 70% capacity. Despite a slight improvement in overall water production, the Delhi Jal Board (DJB) continues to face challenges due to ammonia spikes. The city’s water supply is disrupted whenever ammonia levels rise, as treatment plants struggle to process the polluted water. Previous discussions on addressing ammonia pollution have not led to effective solutions. DJB's efforts to invite private companies for treatment technology proposals have not garnered interest, leaving the issue unresolved.
