Thesis Abstract

Abstract
Groundwater contamination is a pressing environmental issue with significant implications for public health and ecosystems. This thesis presents a comprehensive investigation into groundwater contamination in a specific region using hydrogeological and geochemical methods. The study aims to identify sources of contamination, assess the extent of pollution, and propose mitigation measures to safeguard groundwater quality. The introductory chapter provides a background to the study, highlighting the importance of groundwater as a vital resource and the risks posed by contamination. The problem statement underscores the need for targeted investigations to address contamination issues in the specific region under study. The objectives of the study focus on characterizing the hydrogeological setting, identifying potential sources of contamination, and evaluating the impact on groundwater quality. The methodology chapter outlines the research approach, including field investigations, sampling protocols, laboratory analyses, and data interpretation techniques. Various geophysical and geochemical methods are employed to delineate groundwater flow paths, assess contaminant transport mechanisms, and identify potential sources of pollution. The sampling strategy considers spatial and temporal variability to capture the dynamic nature of groundwater contamination. The literature review chapter synthesizes existing knowledge on groundwater contamination, hydrogeological processes, and geochemical indicators of pollution. Key concepts such as aquifer properties, contaminant fate and transport, and groundwater vulnerability are explored to provide a theoretical framework for the study. The review also discusses relevant case studies and methodologies used in similar investigations, informing the research design and interpretation of results. The findings chapter presents a detailed analysis of field data, laboratory results, and modeling outcomes. Spatial maps, cross-sections, and statistical analyses are used to visualize the distribution of contaminants, assess their migration pathways, and quantify their concentrations in groundwater. The identification of potential pollution sources is supported by geochemical fingerprinting and isotopic analyses, enhancing the understanding of contamination mechanisms. The discussion chapter critically evaluates the findings in relation to the research objectives, highlighting key insights, uncertainties, and implications for groundwater management. The role of hydrogeological factors, anthropogenic activities, and natural processes in shaping groundwater quality is elucidated, providing a holistic perspective on contamination issues in the study area. In conclusion, this thesis contributes to the understanding of groundwater contamination in the specific region through a multidisciplinary approach integrating hydrogeological and geochemical methods. The significance of the study lies in its potential to inform policy decisions, guide remediation efforts, and enhance monitoring strategies to protect groundwater resources. Recommendations for future research and practical interventions are proposed to address ongoing challenges and ensure the sustainable management of groundwater quality in the study area.
