VARIATIONS IN GROUNDWATER QUALITY UNDER DIFFERENT LAND COVERS IN DELHI, INDIA | Journal of Global..

Groundwater is one of Delhi's most important sources of drinking water, and it has been classified as an endangered water resource due to declining quality and quantity. The current study considers spatial variation in groundwater quality and depth with regard to different land covers during pre and post monsoons to investigate the effects of land covers on groundwater quality and depth. The quality of groundwater was investigated under three different land coverings and settlement areas. According to physico-chemical investigation, the most appropriate groundwater for drinking purposes is found in protected forest areas, with water available at a maximum depth of more than 40 mbgl. Groundwater outside of the forest has a minimum depth but maximum values for EC, TDS, hardness, calcium, magnesium, and chloride, making it unfit for human consumption. The quality and depth of groundwater vary dramatically with different land coverings, but ANOVA does not find seasonal variation to be significant. According to the Piper diagram, calcium, magnesium, and chloride predominate in Delhi's groundwater.
