Data underlying the article: A geometrical method for quantifying endmembers' fractions in three‐component groundwater mixing

In this file the chemical analyses of groundwater samples from Ferrarelle aquifers (Riardo plain, southern Italy) and related data elaborations are reported. The data elaborations consist in correlations computing and fractions estimation of the investigated groundwater three component mixing. The dataset consists in four sheets: 1) "Row data" sheet reports the monthly chemical analyses of sampled groundwater from each well analyzed for major ions, minor and trace elements (IC and ICPMS analyses). 2) "correlation matrix" sheet reports the correlations computed among all the analyzed chemical variables. 3) "algebraic mixing computations" reports the computing of three component mixing fractions through the traditional mass balance equations and the related uncertainties. 4) " EMMA mixing computations" reports the computing of three component mixing fractions through EndMember Mixing Analysis (EMMA method) and the related uncertainties.

本文件记录了来自意大利南部里亚尔多平原费拉雷莱含水层（Ferrarelle aquifers）的地下水样品化学分析结果及相关数据处理成果。本次数据处理涵盖相关性计算与研究区地下水三组分混合比例估算两项工作。本数据集包含四个工作表：1) "原始数据（Row data）"工作表记录了各监测井采集的地下水样品的月度化学分析结果，分析项包括常量离子、微量及痕量元素（离子色谱（IC）与电感耦合等离子体质谱（ICPMS）分析）；2) "相关系数矩阵（correlation matrix）"工作表展示了所有分析化学变量间计算得到的相关系数；3) "代数混合计算（algebraic mixing computations）"工作表记录了通过传统质量平衡方程计算得到的三组分混合比例及其相关不确定度；4) "EMMA混合计算"工作表记录了通过端元混合分析（EndMember Mixing Analysis，EMMA方法）计算得到的三组分混合比例及其相关不确定度。
