The objective of this work was to determine the groundwater quality from semi-arid areas using physicochemical parameters, main dissolved constituents, boron, and selected metals and by taking as an example the Plio-Quaternary and Turonian aquifers of the Essaouira basin from western Morocco. The piezometric map shows that the groundwater flow is from the South-East to the North-West with a hydraulic gradient varying between 1.6 and 2.1%. Analytical results show that (1) groundwaters belong to the Na-Cl or Ca–Mg–Cl facies, (2) the groundwater mineralization is the result of the dissolution, base exchange, and marine intrusion processes. The concentrations of different metals in the water of the aquifers studied are relatively low and below the World Health Organization standards. The overall quality of the groundwaters hosted in the Plio-Quaternary and Turonian aquifers is medium to poor and not suitable for drinking. A suitable treatment should be considered before use.

这项工作的目的是使用理化参数，主要溶解成分，硼和某些金属，并以摩洛哥西部索维拉盆地的第四纪和第四纪含水层为例，从半干旱地区确定地下水质量。测压图显示，地下水流从东南向西北流，水力梯度介于1.6％和2.1％之间。分析结果表明，（1）地下水属于Na-Cl或Ca–Mg–Cl相，（2）地下水矿化是溶解，碱交换和海相侵入过程的结果。研究的含水层中水中不同金属的浓度相对较低，低于世界卫生组织的标准。Plio-第四纪和Turonian含水层中地下水的总体质量中等至较差，不适合饮用。使用前应考虑适当的治疗方法。
