Abstract: 
Hydrogeological modeling plays a crucial role in safeguarding underground water sources during energy extraction activities, such as oil and gas drilling, hydraulic fracturing, geothermal energy production, and coal mining. These activities pose significant risks to groundwater, including contamination, depletion, and structural damage to aquifers. This study outlines a comprehensive approach to hydrogeological modeling aimed at understanding and mitigating these risks. The modeling process begins with extensive data collection, including geological, hydrological, chemical, and land use data, sourced through field surveys, remote sensing, and existing databases. This data informs the development of a detailed geological framework and parameterization of hydrological properties, such as hydraulic conductivity, porosity, and recharge rates. Boundary and initial conditions are established to reflect the real-world conditions of the study area. Calibration and validation of the model are achieved through manual and automated techniques, ensuring the model's accuracy and reliability. Various extraction scenarios are then simulated, including baseline, worst-case, and mitigation scenarios, to assess potential impacts on groundwater quality, levels, and aquifer integrity. Risk assessment methodologies, both probabilistic and deterministic, are employed to quantify these impacts. The study also explores mitigation and management strategies, emphasizing preventative measures like safe drilling practices and monitoring systems, as well as remediation techniques for contamination and aquifer restoration. Regulatory and policy frameworks are considered essential for ensuring compliance and effective management. Through case studies of successful implementations, the study highlights best practices and lessons learned, offering valuable insights for future research and development in hydrogeological modeling. This comprehensive approach ensures that energy extraction can proceed while minimizing adverse effects on vital underground water resources.
