Mandi: A analysis workforce from the Indian Institute of Know-how Mandi, beneath the management of Dr. Dericks Reward Shukla, Affiliate Professor on the Faculty of Civil and Environmental Engineering, IIT Mandi, alongside together with his PhD scholar Ms. Harsimranjit Kaur Romana, has carried out analysis to achieve worthwhile insights into human activity-induced groundwater air pollution, with a specific concentrate on agricultural runoff in Punjab. This analysis goals to higher perceive and handle the challenges associated to groundwater air pollution brought on by agricultural actions within the area.
Punjab, as with most agriculture-centric states of India, has skilled a profound shift in its crop patterns during the last half-century, primarily as a result of Inexperienced Revolution. This transformation has led to the dominance of mono-cropping of high-yielding types of rice and wheat, making Punjab the second-largest contributor to wheat manufacturing in India. Sadly, these intensive agricultural practices have resulted in extreme groundwater exploitation, with over 74% of the irrigation necessities being met by way of groundwater within the absence of excellent monsoon. Within the final 20 years, the groundwater demand has elevated as a result of absence of monsoon.
The depth of groundwater wells has elevated as a result of reducing of groundwater ranges because of this the standard of groundwater is repeatedly deteriorating. The groundwater division and native farmers have to take advantage of groundwater from deeper geological strata that are enriched in heavy metals and few are radioactive having severe well being impacts.
The prolific agricultural exercise has come at a major value – groundwater air pollution. Since 94% of the inhabitants of Punjab depends on groundwater for his or her ingesting water wants, the air pollution of groundwater has resulted in severe well being points. Punjab as soon as celebrated because the “bread bowl of India”, is now infamously known as the “most cancers capital” of India, reflecting the dire penalties of water air pollution and its affect on human well being.
Whereas a number of research have highlighted groundwater high quality points in India, an intensive time-based and place-based evaluation of the area has been missing. The IIT Mandi research sought to handle this crucial hole.
Explaining the motive of the research, Dr. D.P. Shukla, Affiliate Professor, Faculty of Civil and Environmental Engineering, IIT Mandi, stated, “We aimed to evaluate how groundwater high quality for ingesting functions modified from 2000 to 2020 at totally different locations. It additionally sought to look at ten-year developments in well being hazards related to contaminants like nitrate and fluoride, together with figuring out areas with notably subpar groundwater high quality.”
The findings of this complete analysis have been revealed within the journal “Environmental Science and Air pollution Analysis”. The paper was co-authored by Ms. Harsimranjit Kaur Romana, Prof. Ramesh P. Singh, and Dr. Dericks Reward Shukla.

The research concerned the measurements of pH, electrical conductivity (EC), and numerous ions from over 315 websites in Punjab. The outcomes revealed a disturbing development, with water high quality declining within the southwestern area of Punjab, adversely affecting the well being of the residents. In distinction, the north-eastern areas, nourished by Himalayan rivers, exhibited comparatively higher water high quality.
This research not solely sheds mild on the alarming state of groundwater air pollution in Punjab but additionally serves as a vital useful resource for policymakers. It underscores the pressing want for mitigation measures and creates consciousness amongst residents concerning the places with unsafe groundwater for ingesting.

These findings emphasize that rapid consideration of the state authorities is required to analyze the standard of groundwater for ingesting and irrigation functions. The research’s insights are anticipated to catalyze actions geared toward safeguarding this invaluable useful resource and the well being of the inhabitants.
