Air-quality levels continue to worsen in several industrial regions of UP, Maharashtra, Gujarat and Rajasthan despite pollution abatement plans in place for critically polluted areas
Uttar Pradesh and Maharashtra had the greatest number of ‘critically polluted’ industrial regions in India, according to a recent analysis by Delhi-based thinktank, Centre for Science and Environment (CSE).
CSE researchers analysed the 2018 Comprehensive Environmental Pollution Index (CEPI) air assessment score that depicts the air quality in industrial regions.
They found out that as many as 13 industrial areas in UP, seven in Maharashtra, eight in Gujarat and five in Rajasthan were still critically / severely polluted with respect to the 2009 air quality levels in these regions.
Mathura, Bulandshahr, Ferozabad, Moradabad in Uttar Pradesh; Chandrapur and Tarapur in Maharashtra; Vadodara and Ankleshwar in Gujarat; Jodhpur and Bhiwadi in Rajasthan were found to be the top critically polluted regions with a high CEPI air score.
The CEPI scores in the following clusters clearly portray the concerning levels of air quality in these industrial regions:
States with a considerable number of critically / severely polluted air quality regions
A CEPI air score of 60 and above denotes an industrial area to be ‘critically polluted’ and a score between 50-60 classifies it to be ‘severely polluted’.
|Number of industrial clusters identified as critically / severely polluted||Critically polluted
|CEPI 2018 (air) score >=60||CEPI 2018 (air) score: between 50-60|
|Uttar Pradesh||13||Mathura, Bulandshahr-Khurja,
Ferozabad, Moradabad, Gajraula, Varanasi-Mirzapur, Kanpur, Agra
|Noida, Ghaziabad, Aligarh, Meerut, Haridwar|
|Gujarat||8||Vadodara, Ankleshwar, Vapi, Bhavnagar||Vatva, Ahmedabad, Rajkot, Morbi|
|Maharashtra||7||Chandrapur, Tarapur, Dombivalli, Nashik, Navi-Mumbai, Chembur, Pimpri-Chinchwad||-|
|Rajasthan||5||Jodhpur, Bhiwadi, Pali, Sanganer Industrial Area, Jaipur||-|
|West Bengal||4||Howrah, Durgapur||Bandel, Asansol|
|Jharkhand||5||Hazaribagh||Saraikela, Ramgarh, Singhbum-West, Bada Jamtara|
Top regions with worsening air quality: A comparison of 2009 and 2018 CEPI air score
CSE also compared the latest 2018 assessment scores for air with the 2009 scores. We found out that from the 2009 levels, air quality had worsened in several industrial clusters.
The majority of these industrial regions belong to Uttar Pradesh. A drastic increase in CEPI air scores was observed in Mathura, Bulandshahr, Moradabad and Ferozabad in Uttar Pradesh, Najafgarh drain basin in Delhi comprising of Anand-Parvat, Naraina, Okhla and Wazirpur areas, Vadodara in Gujarat, Jodhpur and Pali in Rajasthan and Durgapur in West Bengal.
CEPI (air quality) assessment 2009 versus 2018
What is a CEPI index?
CEPI is a nationwide index that was developed to represent the quality of ambient air, surface water, groundwater and soil of a particular industrial region or cluster with a score.
The overall CEPI score was calculated based on the individual score assessment for air pollution, surface water pollution, groundwater and soil pollution in the identified cluster.
The regions were ranked as ‘critically polluted area’, ‘severely polluted area’ and ‘other polluted areas’, depending upon the CEPI scores of each of these industrial areas.
A CEPI air score of 60 and above denotes an industrial area to be ‘critically polluted’ and a score between 50-60 classifies it to be ‘severely polluted’ with respect to air quality.
CEPI assessment was first carried out by CPCB in 2009-10 and has been done periodically since then in 2011, 2013 and 2018. The aim of CEPI assessment was to identify, declare and prioritize critically polluted and severely polluted regions in order to formulate comprehensive remedial action plans for pollution abatement in identified regions.
Periodic CEPI assessment reflects the current environmental quality of the region and also serves as a yardstick to assess the implementation of action plans.
