A preliminary hydrogeochemical investigation of groundwater quality for spatially distributed habitations of Chandel district of Manipur was carried out with an objective to assess the suitability of groundwater for different anthropogenic uses. Altogether, eighteen (18) physico-chemical parameters including in situ parameters and major ions were analysed for classification and hydrogeochemical characterisation of groundwater resources of the study area. Some of the anions such as Cl and SO42− were found in exceeding concentrations. Similarly, 23.1% samples exceed fluoride (F) concentration beyond the permissible limit of 1.5 mg/l. The water quality index of the groundwater samples of the habitations was found to be influenced by the elevated concentrations of water quality parameters such as F, EC, TDS, salinity, Cl and SO42−. The geochemical analysis reveals that the majority of geochemical facies of the groundwater samples are dominated by Na+–Ca2+–Mg2+–Cl–HCO3–SO42− type of water resulting from rock-weathering geochemical process. Bivariate and multivariate analysis indicates the influences of hydrogeochemical interactions in the aquifer on the overall water quality. The irrigational water quality indices demonstrate that the water qualities of most of the sources are within the acceptable range except for few samples with high salinity and alkali hazards.

印度曼尼普尔(Manipur)昌德尔区(Chandel District)很少有人居住的地下水质量的水文地球化学评估

进行了曼尼普尔邦昌德地区空间分布的居住区地下水水质的初步水文地球化学调查,目的是评估地下水对不同人为用途的适用性。总共分析了十八(18)个物理化学参数,包括原位参数和主要离子,以对研究区域的地下水进行分类和水文地球化学表征。一些阴离子如Cl的-和SO 4 2-均在超过浓度找到。同样,23.1%的样品超过氟化物(F -)浓度超过1.5 mg / l的允许极限。被发现的住处的地下水样品的水质指标由升高的浓度的水质量参数如F的影响-,EC,TDS,盐度,氯-和SO 4 2-。地球化学分析表明,地下水样品的大多数地球化学相以Na + -Ca 2+ -Mg 2+ -Cl -- HCO 3 -- SO 4 2-为主。岩石风化地球化学过程产生的水的类型。双变量和多变量分析表明了含水层中水文地球化学相互作用对整体水质的影响。灌溉水质量指数表明,除少数具有高盐度和碱危害性的样品外,大多数水源的水质都在可接受的范围内。
