In arid areas, the pressure on water resources and in particular on groundwater resources is on the rise, mainly due to increasing demand and the deterioration of water quality. In this context, the present work aims to follow the annual evolution, between 2009 and 2019 of the physicochemical parameters, and to evaluate the quality of groundwater of the region of Mougheul, by determining the data of pH, TDS, conductivity and the concentrations of major ions ( Ca⁺², Mg⁺², Na⁺, K⁺, Cl⁻, HCO₃⁻, SO₄⁻², NO₃⁻) of 07 water points. The results revealed that all the levels of the physicochemical parameters do not exceed the WHO potability standards, except high values were observed at the level of well W6 which exceeds the limits recommended by the WHO (50 mg /l). The diagram of Schöeller and Berkaloff shows that the groundwater has the bicarbonate magnesium facies. The representation of the data on the Piper triangular diagram shows that W6 has the facies chlorinated and calcium sulfate and magnesium and the other water points have the facies bicarbonate calcium and magnesium. SAR values show that the groundwater of Mougheul is excellent for irrigation. The classification according to the Wilcox diagram shows that the groundwater of Mougheul in general is good quality, but the well of W6 water is suitable for irrigation and requires monitoring the evolution of salinity.

在干旱地区，对水资源特别是对地下水资源的压力正在上升，这主要是由于需求增加和水质恶化。在这种情况下，目前的工作旨在追踪2009年至2019年之间理化参数的年度变化，并通过确定pH值，TDS，电导率和水的浓度来评估Mougheul地区的地下水质量。主要离子（钙²，镁²，钠⁺，K ⁺，氯^-，HCO ₃ ^-，SO ₄ ^-2，NO ₃ ^-）的07个水位。结果表明，所有理化参数水平均未超过WHO的耐受性标准，除非在W6井水平观察到高值，该值超过了WHO建议的限值（50 mg / l）。Schöeller和Berkaloff的图表显示，地下水具有碳酸氢盐镁相。派珀三角图上的数据表示表明，W6具有氯化相，硫酸钙和镁相，而其他水位具有碳酸氢钙和镁相。SAR值表明，Mougheul的地下水非常适合灌溉。根据Wilcox图进行的分类显示，Mougheul的地下水总体上质量良好，
