The present study focused on the hydrochemistry of groundwater in Kerzaz and Beni Abbes in Saoura oases (southwest of Algeria) to assess the quality of groundwater for determining its suitability for drinking and irrigation purposes. The study area experiences a hyper-arid climate characterized by low rainfall 50–100 mm/year and excessive drought. Groundwater samples were collected from 24 locations to ensure a good spatial distribution to cover all the study areas. Standards laboratory methods were used to determine physicochemical groundwater properties. The result for this study showed that the water was to be found unsuitable for drinking purposes except for few samples in Kerzaz and Beni Abbes. Except for PI values, all other physicochemical parameters (EC, SAR, MAR), and according to the US salinity diagram, groundwater in Kerzaz was to be found satisfactory for irrigation especially if the soil permeability is improved and the leaching is guaranteed by applying extra frequently irrigation. In Beni Abbes, 58.33% of water samples show that water can be used if rapid permeability is guaranteed, which is the case in Beni Abbes soils, and 25% present medium salinity and low to medium alkalinity (C2S1, C2S2, C3S3) and only the natural spring presents a low salinity and low alkalinity C1S1 permitting the use of water for irrigation with most crops on most soil. Piper diagram indicates groundwater in Kerzaz belongs to CaCl type, while in Beni Abbes four types were recognized, NaCl, CaMgHCO₃, CaCl and mixed CaCl type with 16.66%, 8.33%, 41.66% and 33.33%, respectively.

阿尔及利亚西南部Saoura山谷的Kerzaz和Beni Abbes地下水的质量评估和水文地球化学特征

本研究的重点是索拉绿洲（阿尔及利亚西南部）的喀尔扎兹（Kerzaz）和贝尼阿贝斯（Beni Abbes）的地下水水化学，以评估地下水的质量，以确定其是否适合饮用和灌溉。研究区域经历了高干旱气候，其特征是每年降雨量低至50-100 mm，干旱严重。从24个地点收集了地下水样本，以确保良好的空间分布，覆盖所有研究区域。使用标准实验室方法确定理化地下水特性。这项研究的结果表明，除了克扎兹和贝尼阿贝斯的少量样本外，发现该水不适合饮用。除PI值外，所有其他理化参数（EC，SAR，MAR），并根据美国盐度图，人们发现喀尔扎兹州的地下水对灌溉来说是令人满意的，特别是如果土壤渗透性得到了改善，并且通过频繁灌溉可以保证淋溶。在贝尼阿贝斯，有58.33％的水样表明，只要保证了快速渗透性，便可以使用水，贝尼阿贝斯土壤就是这种情况，只有25％的水具有中等盐度和中低碱度（C2S1，C2S2，C3S3），仅天然泉水的盐度和碱度较低，因此C1S1可以用于大多数土壤和大多数作物上的灌溉用水。移液器图表明，Kerzaz中的地下水属于CaCl类型，而在Beni Abbes中，识别出了四种类型：NaCl，CaMgHCO 33％的水样表明，只要能保证快速渗透，就可以使用水，贝尼阿贝斯土壤就是这种情况，并且25％的水具有中度盐度和中度至中度碱度（C2S1，C2S2，C3S3），并且只有天然泉水存在低盐度和低碱度的C1S1允许在大多数土壤上的大多数农作物上使用灌溉水。移液器图表明，Kerzaz中的地下水属于CaCl类型，而在Beni Abbes中，识别出了四种类型：NaCl，CaMgHCO 33％的水样表明，只要能保证快速渗透，就可以使用水，贝尼阿贝斯土壤就是这种情况，并且25％的水具有中度盐度和中度至中度碱度（C2S1，C2S2，C3S3），并且只有天然泉水存在低盐度和低碱度的C1S1允许在大多数土壤上的大多数农作物上使用灌溉水。移液器图表明，Kerzaz中的地下水属于CaCl类型，而在Beni Abbes中，识别出了四种类型：NaCl，CaMgHCO_{如图3所示}，分别为16.66％，8.33％，41.66％和33.33％的CaCl和混合CaCl类型。
