Najafgarh basin Delhi’s most polluted area

Till now, pollution levels in residential areas of Delhi were known to be dangerously high. But a new methodology to calculate the pollution in air, water and land has detected some new villains.

A nationwide study by the Central Pollution Control Board on the most polluted industrial clusters shows that despite polluting manufacturing units being moved out of Delhi, not just the suburbs, but Capital's heart too, is critically polluted.

The new system looks at presence of toxins, carcinogens and their impact on human life and land. And according to it, Delhi's 'Najafgarh drain basin' — Anand Parvat, Naraina, Okhla, and Wazirpur — ranks eleventh among the 88 most polluted industrial clusters in India. Neighbouring 'green' suburbs Noida, (no. 12) Ghaziabad (no. 3) and Faridabad (no. 18) are also highly polluted. Ankleshwar in Gujarat occupies the top slot in pollution, the second spot is held by Vapi, also in Gujarat.

Delhi: 65 Faridabad: 62 Ghaziabad: 71
