In the present investigation, hydrogeochemistry and multivariate statistical analysis of groundwater quality were assessed from hard rock aquifers of the Deccan trap basalt in the Jalna district of Maharashtra. Groundwater samples (n = 105) were collected from the study area in a systematic grid pattern to avoid biasing in sampling. Water quality parameters of all these groundwater samples were analyzed by standard BIS and APHA procedures by titrimetric and using sensors. Uranium in all samples was analyzed using an LED fluorimeter. Strict quality assurance and quality control features were adopted in all stages of the study to ensure the quality of the data. The observed sequence of the dominance of major cations and anions is Ca²⁺ > Na⁺ > Mg²⁺ > K⁺ and HCO³⁻ > Cl⁻ > SO₄²⁻ respectively. The observed uranium values were in the range of 0.1 to 16.2 µg/L with an average value of 2.04 µg/L, well below the safe limits recommended by WHO and AERB i.e. 30 and 60 µg/L, respectively. Piper trilinear diagram indicates dominant hydrochemical facies of groundwater in the study area are Mixed Ca²⁺–Na⁺–HCO₃⁻, Na⁺–Cl⁻ and Ca⁺–HCO₃⁻ while Gibbs plot infers host rock-water interaction is the major geochemical process in these aquifers. The correlation analysis, cluster analysis, and factor analysis tests are performed. Groundwater was assessed for its suitability for irrigation purposes using multiple indices such as SAR, RSC, and Na percentage. From the estimated indices, it was found that the groundwater in hard rock aquifers of the Deccan trap basalt is suitable for irrigation purposes.

在本次调查中，从马哈拉施特拉邦贾尔纳地区的德干圈闭玄武岩的硬岩含水层评估了地下水水质的水文地球化学和多元统计分析。 从研究区域以系统化的网格模式收集了地下水样本（n = 105），以避免抽样偏差。所有这些地下水样品的水质参数均通过标准BIS和APHA程序通过滴定法和使用传感器进行分析。使用LED荧光计分析所有样品中的铀。在研究的所有阶段都采用了严格的质量保证和质量控制功能，以确保数据的质量。观察到的主要阳离子和阴离子的主导顺序为Ca ²⁺ > Na ⁺  > Mg ²⁺>ķ ⁺和HCO ^3-  >氯^-  > SO ₄ ^2-分别。观察到的铀值在0.1至16.2 µg / L的范围内，平均值为2.04 µg / L，远低于WHO和AERB建议的安全限值，分别为30和60 µg / L。荜三角坐标图表示在研究区地下水主导水化学相混合的Ca ²⁺ -Na ⁺ -HCO ₃ ^- ，钠⁺ -Cl ^-和Ca ⁺ -HCO ₃ ^-而吉布斯图则推断宿主岩水相互作用是这些含水层的主要地球化学过程。进行了相关性分析，聚类分析和因子分析测试。使用SAR，RSC和Na百分比等多个指标评估了地下水是否适合灌溉。从估计的指数中发现，Deccan陷井玄武岩的硬岩含水层中的地下水适合灌溉。
