Popis: Hydrogeochemical evaluation and assessment of groundwater quality was carried for selected areas of Bishnupur district of Manipur to ensure its suitability for drinking and irrigational uses. Twenty physico-chemical parameters of groundwater samples from thirty-one spatially distributed areas were assesed including major geogenic contaminants such as Fe3+, As3+ and F− to ensure public health safety. In-situ parameters such as temperature, pH, EC, DO, salinity, ORP, TDS were determined using field sensors and other parameters were analysed using standards methods. The suitability of groundwater for potable use was assessed using drinking water quality index based on World Health Organisation standards. Groundwater quality indices exhibit very poor results due to presence of high dissolved solids, higher values of EC, excessive hardness and presence of geogenic contaminants in the groundwater samples. Irrigational water quality of groundwater resources showed satisfactory results according to the various irrigational water quality parameters and indices. Geochemical evaluation showed most of the groundwater sources are dominated by Ca-Mg-Na-HCO3−-Cl− type of water mainly originated from silicate and carbonate rock-weathering or dissolutions processes.
