The construction of the New Galala City besides great mining (e.g., konoozmisr) and Seawater Reverse Osmosis Desalination Plant projects in the semiarid Gulf of Suez region of Egypt increases the demand for groundwater resources. So, the current research provides integrated stratigraphical, hydrogeochemical, and geophysical studies to investigate the shallow groundwater aquifers in Wadi Araba area on the western side of the Gulf of Suez. The stratigraphic column starts with pre-Cambrian basement rocks which are non-conformably overlain by sedimentary succession of Phanerozoic Erathem. A detailed land magnetic profile has been conducted and processed to estimate the aquifer’s geometrical parameters. This includes the subsurface spatial extension and thickness to delineate the prevailed subsurface structures in the study area. Lithostratigraphically, these aquifers are represented by the Paleozoic- lower Cretaceous siliciclastic-dominated sediments of the Nubia Group and fractured carbonate-dominated facies of the upper Cretaceous Galala Formation. Lithological characters, sedimentary facies (fluvial to shallow and open marine), microfacies types, and diagenesis processes (e.g., compaction, cementation, dissolution, and fracturing) are the main factors that affect the quality of the shallow aquifers in the study area. The main microfacies of the studied aquifers are quartz arenite, subarkose, sublitharenite, mudstone/wackestone, and packstone/grainstone. These facies are characterized by different primary and secondary porosities. According to the water sampling standard methods, nineteen groundwater samples were collected from the available hand-dug wells and springs from the Nubian sandstone aquifer and the Upper Cretaceous aquifer, respectively. Inductively coupled plasma–mass spectrometry (ICP–MS), titration, spectrophotometer and a flame photometer were used to obtain a complete chemical analysis. The results of hydrochemical analyses indicated that total dissolved solids (TDS) and concentrations of major ions as well in the lower Cretaceous aquifer increase toward the Gulf of Suez and in general higher than that of springs of the Upper Cretaceous Aquifer. The predominant factors influencing groundwater chemistry include seawater intrusion, evaporation, mineral alteration, dissolution of fossils, and ion exchange. Groundwater in the study area is unsuitable for drinking except in one sample and moderately suitable for irrigation with caution for higher salinity in samples located near the Gulf of Suez.

埃及半干旱的苏伊士湾地区除了大型采矿（如konoozmisr）和海水反渗透淡化厂项目外，新加拉拉城的建设增加了对地下水资源的需求。因此，当前的研究提供了综合地层、水文地球化学和地球物理研究来调查苏伊士湾西侧瓦迪阿拉巴地区的浅层地下水含水层。地层柱始于前寒武纪基岩，这些基岩被显生宙 Erathem 的沉积序列非整合地覆盖。已经进行和处理了详细的陆地磁力剖面，以估计含水层的几何参数。这包括地下空间延伸和厚度，以描绘研究区域中普遍存在的地下结构。在岩石地层上，这些含水层以努比亚群古生界-下白垩统硅质碎屑为主的沉积物和上白垩统加拉拉组以裂隙碳酸盐为主的相为代表。岩性特征、沉积相（河流到浅海、开阔海相）、微相类型以及成岩作用（压实、胶结、溶蚀、压裂等）是影响研究区浅层含水层质量的主要因素。研究的含水层的主要微相是石英砂岩、水下长石、水下砂岩、泥岩/砂岩、泥岩/粒岩。这些相的特征是具有不同的原生和次生孔隙度。根据水采样标准方法，分别从努比亚砂岩含水层和上白垩统含水层的现有手挖井和泉水中采集了19个地下水样品。使用电感耦合等离子体质谱（ICP-MS）、滴定、分光光度计和火焰光度计来获得完整的化学分析。水化学分析结果表明，下白垩统含水层中的总溶解固体（TDS）和主要离子浓度向苏伊士湾方向增加，总体高于上白垩统含水层泉水。影响地下水化学的主要因素包括海水入侵、蒸发、矿物蚀变、化石溶解和离子交换。研究区域的地下水除一个样本外不适合饮用，中等程度适合灌溉，但苏伊士湾附近样本的盐度较高，需谨慎。
