To achieve the goal of water security, particularly in rapidly expanding areas, identification of safe and sustainable water resources is an absolute necessity. The present study conducted an exploratory investigation of the hydrogeochemical characteristics of groundwater and thereby assessed the suitability of groundwater as an alternative and reliable resource for public use in the Khoyrasole block, Birbhum district, India. A total of 15 groundwater samples, collected from bore wells spread well over the Khoyrasole block have been considered. After the hydrogeochemical analysis, the study evaluated the present state of the groundwater quality and determined the spatial distribution of groundwater quality parameters such as pH, Total Dissolved solids (TDS), Hardness, Calcium, Magnesium, Sodium, Potassium, Iron, Chloride, Carbonate, Bicarbonate, Sulphate, Nitrate and Fluoride. High to very high levels of iron and fluoride have been observed to be present in 67% and53% of the samples respectively.Based upon the calculated parameters like SAR, MAR, PI and Chloro Alkaline Indices, groundwater of Khoyrasole block is majorly suitable for the purpose of agriculture and irrigation.Plotting of ionic scatter plots and geochemical facies also indicate the water samples to be of ‘fresh water’ category, with no dominant cation or anion playing a selectively dominant role in influencing the groundwater chemistry in the region.
