Abstract
This study utilized the DRASTIC approach combined with GIS technology to assess groundwater vulnerability and contamination risks in a research area. The DRASTIC simulation generated a risk assessment map, categorizing locations based on vulnerability levels. The analysis revealed varying vulnerability levels, with areas of significant industrial activity and high population density exhibiting elevated nitrate levels in nearby wells. The model’s outcomes were validated against field measurements of nitrate concentrations, demonstrating a high degree of consistency. The R-index technique was employed to assess sensitivity to nitrate contamination, identifying areas at greater risk. The study highlights the importance of considering hydrogeological characteristics and agricultural practices for groundwater protection and management. Overall, the DRASTIC approach proves valuable in assessing groundwater risks and informs decision-making for sustainable resource management.
