Groundwater quality assessment in different land-use areas of Faridabad and Rohtak cities of Haryana using deviation index

Physico-chemical parameters were analysed to evaluate the groundwater quality of the two important cities of Haryana, Faridabad and Rohtak, and the pollution status of groundwater was compared using deviation index (DI). Groundwater of both the cities had high alkalinity, hardness, total dissolved solids (TDS) and electrical conductivity. The groundwater of Faridabad showed low fluoride concentration whereas in 74% of groundwater samples of Rohtak the fluoride levels were high. Land use and waste disposal practices were found to have an important effect on groundwater pollution.
