Abstract

The escalating global concern over the pollution of freshwater resources, driven by the amplifying stress and scarcity of freshwater, underscores the significance of this study. The investigation examined the alterations in land use and land cover (LULC) in Delhi, concurrently assessing the coliform count in water sources designated for drinking and other purposes. LANDSAT 7 satellite imagery scrutinized the LULC changes in Delhi over a decade (2011 to 2021) to discern the impact of urban development. The outcomes of the LULC analysis reveal a noteworthy 2.03% expansion in built-up areas, while a reduction of 3.3% in forested regions and 0.43% in water bodies within the Delhi landscape. The amalgamation of mapping results with water quality data from the Central Pollution Control Board (CPCB) indicates a compromised supply of freshwater resources, particularly prevalent in South and Southwest Delhi. Additionally, biological data from the National Water Quality Monitoring Programme (NWMP) by the CPCB underscores that none of the sampled sites adhere to the drinking water standards prescribed by the CPCB. Notably, specific sites in South Delhi, namely Fateh Pur Beri, Pilanji, and Vasant Kunj, exhibit coliform counts surpassing 50 MPN/100 ml, which is unfit for bathing purposes as well. The comprehensive findings collectively illuminate the substantial footprint of urbanization in Delhi and its presumed impact on groundwater quality in the Delhi region. Furthermore, the study brings to light an ancient stepwell with sulfur-rich water that has sustained through urban sprawl and the continuous deterioration of water quality over the years.
