Delhi-NCR is once again grappling with severe air pollution and the disheartening return of thick, toxic white foam on the Yamuna River. The foam, a recurring environmental concern, has been observed covering large stretches of the river near Kalindi Kunj, signaling persistent pollution challenges.
Air Quality Deteriorates, GRAP-1 Enacted
The region's overall Air Quality Index (AQI) has climbed to 168, indicating 'moderate' air quality but with significant health implications for sensitive groups. Monitoring stations across Delhi reported varied readings, with PM2.5 and PM10 identified as the primary pollutants contributing to the poor air quality.
In response to the escalating pollution levels, the Commission for Air Quality Management (CAQM) activated Stage 1 of the Graded Response Action Plan (GRAP) on October 21. This initial stage imposes several restrictions aimed at curbing emissions:
- Prohibition on the use of coal and firewood in tandoors at hotels, restaurants, and open-air eateries.
- Restriction on the use of diesel generators, allowing them only for essential or emergency purposes.
These measures are a proactive step to prevent further deterioration of air quality as the capital heads into the winter months, a period notorious for severe smog.
Yamuna Restoration Efforts Face Setback
The reappearance of the foam comes just days after Delhi Chief Minister Rekha Gupta had highlighted the government's ongoing efforts to restore the Yamuna. Chief Minister Gupta had recently inaugurated infrastructure projects valued at approximately ₹9,000 crore, specifically aimed at the river's rejuvenation and overall urban development.
Addressing the media, Chief Minister Gupta stated, "Today is a joyful day for the people of Delhi, as projects worth around ₹9,000 crores have been inaugurated today. We can say that the way the government has started work for the rejuvenation of the River Yamuna, in one and a half years of tenure, we have continuously moved forward strongly in that direction." She further expressed resolve to ensure a clean, free-flowing Yamuna for Delhi residents within a few years, building on previous investments of ₹9,000-10,000 crore.
However, the visible chemical foam at Kalindi Kunj starkly underscores the immense scale of the environmental challenge that remains, despite significant governmental investment and stated commitments.
