Toxic foam covers Yamuna River as pollution spikes ahead of Chhath Puja in Delhi-NCR

Toxic foam has covered the Yamuna River ahead of Chhath Puja, raising pollution concerns in Delhi-NCR. Authorities are using chemical defoamers to address the issue, which is linked to high levels of untreated sewage and industrial waste. The Delhi Jal Board has begun spraying anti-foaming agents at the Okhla barrage, applying about 12-15 tons before the festival from November 6 to 8. This foam problem occurs every winter due to ongoing pollution. Air quality in Delhi has also worsened, with the Air Quality Index reaching 369, up from 290 the previous day. Several areas reported 'severe' air quality, with readings exceeding 400 at multiple monitoring stations.
