摘要:In order to attain the water security goal, specifically in highly developingareas, delineation of pure and sustainable water resources is of utmostpriority. In the present study, a preliminary investigation of the groundwaterchemistry was carried out. This was followed by assessing the suitabilityof groundwater to be used as an alternative and reliable resource for publicuse in the Khoyrasole block, Birbhum district, India. Altogether 15(fifteen)samples of groundwater, were collected from bore wells spread well overthe Khoyrasole block have been considered. After completing the chemicalanalysis of the groundwater samples, the study revealed the quality ofgroundwater. The spatial distribution of groundwater quality parameterssuch as pH, Total Dissolved solids (TDS), Hardness, Calcium, Magnesium,Sodium, Potassium, Iron, Chloride, Carbonate, Bicarbonate, Sulphate,Nitrate and Fluoride have also been studied. High to very high levels ofiron and fluoride have been observed to be present in 67% and53% of thesamples respectively. Based upon the calculated parameters like SAR,MAR, PI and Chloro Alkaline Indices, groundwater of Khoyrasole blockis majorly suitable for the purpose of agriculture and irrigation. Plotting ofionic scatter plots and geochemical facies also indicate the water samplesto be of “fresh water” category, with no dominant cation or anion playing aselectively dominant role in influencing the groundwater chemistry in thestudy area.
