Vulnerability analysis in areas vulnerable to anthropogenic pollution has become a key element of sensible resource management and land use planning. This study is intended to estimate aquifer vulnerability using the DRASTIC model and using the vertical electrical sounding (VES) and electrical conductivity (EC) outcomes. The model allows for the identification of hydrogeological environments within the scope of the research, based on a composite definition of each environment’s main geological, geoelectrical, and hydrogeological factors. The results from the DRASTIC model were divided into four equal intervals, high, medium, low, and very low drastic index values. The SW area and NE area depict drastic index values from medium to very high, making it the most vulnerable zone in the study area, while the NW and SW areas show low to very low drastic index values. In addition, the results from the VES and EC the freshwater aquifer in the NE area and brackish water in the SE area, while the rest of the area falls into the category of brackish water. Overall, it can be concluded that areas having freshwater assemblages are on the verge of becoming contaminated in the future while the rest of the NW and SW areas constitute less vulnerable zones. The validation conducted for DRASTIC and EC shows a nearly positive correlation. Wastewater treatment policies must be developed throughout the studied region to prevent contamination of the remaining groundwater.

使用 DRASTIC 指数和地电技术对含水层脆弱性进行分类

易受人为污染地区的脆弱性分析已成为合理资源管理和土地利用规划的关键要素。本研究旨在使用 DRASTIC 模型并使用垂直电测深 (VES) 和电导率 (EC) 结果来估计含水层的脆弱性。该模型允许根据每个环境的主要地质、地电和水文地质因素的复合定义，识别研究范围内的水文地质环境。DRASTIC 模型的结果分为四个相等的区间，即高、中、低和非常低的剧烈指数值。SW 区和 NE 区描绘了从中到极高的剧烈指数值，使其成为研究区中最脆弱的区域，而西北和西南地区显示出低至非常低的剧烈指数值。此外，VES和EC的结果是东北地区的淡水含水层和东南地区的咸水，而该地区的其余部分属于咸水。总体而言，可以得出结论，具有淡水组合的地区在未来即将受到污染，而西北和西南地区的其他地区则构成较不脆弱的地区。对 DRASTIC 和 EC 进行的验证显示出几乎正相关。必须在整个研究区域制定废水处理政策，以防止剩余地下水受到污染。而该地区的其余部分则属于苦咸水。总体而言，可以得出结论，具有淡水组合的地区在未来即将受到污染，而西北和西南地区的其他地区则构成较不脆弱的地区。对 DRASTIC 和 EC 进行的验证显示出几乎正相关。必须在整个研究区域制定废水处理政策，以防止剩余地下水受到污染。而该地区的其余部分则属于苦咸水的范畴。总体而言，可以得出结论，具有淡水组合的地区在未来即将受到污染，而西北和西南地区的其他地区则构成较不脆弱的地区。对 DRASTIC 和 EC 进行的验证显示出几乎正相关。必须在整个研究区域制定废水处理政策，以防止剩余地下水受到污染。
