A new assessment by the Central Pollution Control Board has raised concerns over deteriorating groundwater quality across Punjab, pointing to widespread contamination that could have significant public health and urban infrastructure implications. The findings, submitted to the National Green Tribunal, highlight deviations from drinking water standards in multiple locations, particularly in rural and peri-urban areas.
The study, based on field monitoring across identified sites, found that several key water quality parameters—including total dissolved solids, fluoride, sulphates, and ammoniacal nitrogen—exceeded permissible limits in parts of the state. Elevated levels of arsenic and iron were also detected in certain groundwater sources, indicating potential long-term health risks if untreated water continues to be consumed. Environmental experts attribute the contamination to a combination of factors, including agricultural runoff, untreated sewage discharge, and industrial waste infiltration. Punjab’s intensive farming practices, characterised by high fertiliser and pesticide use, have been flagged as a major contributor to groundwater degradation, particularly in regions dependent on shallow aquifers. The issue extends beyond water quality into broader questions of urban resilience. Cities such as Chandigarh and surrounding urban clusters rely heavily on groundwater reserves for supplementary supply, especially during peak demand periods. Contamination in these reserves increases treatment costs, strains municipal systems, and raises the risk of uneven access to safe drinking water—particularly for low-income and peri-urban communities.
Data from national monitoring programmes further underscores the scale of the challenge. Over recent years, thousands of water samples in Punjab have shown chemical contamination, reflecting systemic stress on both natural aquifers and infrastructure networks. The persistence of pollutants such as fluoride, nitrates, and heavy metals suggests that remediation will require long-term interventions rather than isolated corrective measures. Urban planners note that groundwater contamination is closely linked to land-use patterns and infrastructure deficits. Inadequate sewage treatment, unregulated waste disposal, and leakage from ageing pipelines can accelerate pollutant seepage into aquifers. As cities expand outward, the interface between urban and rural systems becomes more porous, amplifying these risks. The findings also reinforce the need to integrate water quality monitoring into urban planning frameworks. While schemes such as piped water supply expansion aim to reduce dependence on groundwater, gaps in coverage continue to push communities towards local sources that may not meet safety standards. Policy experts suggest that addressing Punjab groundwater contamination will require a multi-layered strategy—combining stricter regulation of industrial discharge, improved wastewater treatment capacity, and a gradual shift towards sustainable agricultural practices. Investments in decentralised water treatment and real-time monitoring systems could also play a critical role in mitigating risks.
As climate variability intensifies pressure on water resources, the quality of existing reserves is becoming as critical as their quantity. For Punjab, the emerging groundwater crisis underscores a broader transition: from managing water supply to safeguarding water systems as essential urban infrastructure. The next phase will depend on how effectively regulatory, environmental, and urban planning systems converge to secure safe and sustainable water access.
