Geochemical and statistical evaluation of groundwater in Imphal and Thoubal district of Manipur, India

► The water quality of Imphal and Thoubal district was good for domestic and agricultural uses. ► The hydrogeochemistry was influenced by kaolinite and Ca montmorillonite minerals. ► Natural weathering, mainly silicate weathering, was the dominant geochemical processes. ► Variations in groundwater quality of the study area with respect to seasons were not prominent. ► Overall, inherent lithology and the land use pattern governed the hydrogeochemistry of study area.
