Faecal coliform levels hit record high in northern India, reporter struggles in river
The incident took place in Delhi city and the video went viral on October 17,
According to reports, the faecal coliform levels, a marker of untreated sewage and extreme pollution, peaked in September. Despite some improvement in dissolved oxygen (DO) and biochemical oxygen demand (BOD) levels due to the surplus rain in August, the pollution remains at alarming levels. The Delhi Pollution Control Committee (DPCC) tested the river on September 4 and released the report on October 4. Meanwhile, parts of the river continued to show visible frothing, a sign of surfactants and phosphates mixing with pollutants.
The retreating monsoon on October 2 helped maintain the flow of the Yamuna, with water being released from upstream. This aided the DO levels slightly, but the health of the river remains in serious question.
