The study area extends along northwestern Sinai coastal plain, which is considered an integral part of the Mediterranean Sea. It depends mainly on the groundwater resource for different type of human activities such as agricultural and drinking. Many programs and policies should be implemented in this area to concurrently improve the sustainability of groundwater use and manage the risks of its degradation. Leakage from some factories in Bir El-Abd might be a contamination source that would threaten groundwater. In this paper, an attempt was made using an integrated approach of the hydrogeological setting and the conjugation of the hydrogeochemical data with the stable isotope hydrology for representation of the conceptual model of the study area. Those tools give more insights on the characterization of the groundwater system with all relevant boundaries and main recharge sources of the aquifer; which is considered to be the key components of a groundwater modeling. A particular focus is placed on modeling a hypothetical accident for contaminant transport in the groundwater system, using both lead and chromium as a typical contaminant component. Further predication of the concentration of those elements has been estimated, and the safety distances of their plume have been determined. This study would be helpful in dealing with water management issues related to contaminant hydrogeology. As well, it introduces some finding for reducing the environmental risk form the industrial development at the study area.
研究区域沿西奈半岛西北沿海平原延伸，该平原被认为是地中海的组成部分。它主要依赖地下水资源来支持各种人类活动，如农业和饮用水供应。为了提高地下水利用的可持续性并管理其退化的风险，该地区需要实施许多计划和政策。Bir El-Abd 地区的一些工厂可能存在泄漏问题，这可能成为地下水的污染来源。本文尝试采用综合方法，结合水文地质背景和水文地球化学数据与稳定同位素水文学，以代表研究区的概念模型。这些工具可以更深入地了解地下水系统的特征，包括所有相关边界和含水层的主要补给源；这些被认为是地下水建模的关键组成部分。本文特别关注模拟地下水系统中污染物运移的假设事故，使用铅和铬作为典型污染物成分。进一步预测了这些元素的浓度，并确定了它们羽流的安全距离。这项研究有助于解决与污染物水文地质学相关的水资源管理问题。同时，它还为减少研究区域工业发展带来的环境风险提供了一些发现。
