Assessment of groundwater quality in urban areas using geophysical methods

Thesis Abstract

Abstract
This thesis explores the assessment of groundwater quality in urban areas using geophysical methods. The study aims to address the increasing concerns regarding groundwater contamination and its potential impact on public health in urban environments. Groundwater is a vital natural resource that serves as a primary source of drinking water for millions of people worldwide. However, urbanization and industrial activities have led to the deterioration of groundwater quality, posing significant challenges for sustainable water management. The research methodology employed in this study involves the application of geophysical methods, such as electrical resistivity imaging, ground-penetrating radar, and electromagnetic induction, to assess the spatial distribution of groundwater contaminants in urban areas. These geophysical techniques enable non-invasive and cost-effective characterization of subsurface properties, facilitating the identification of potential sources of contamination and the delineation of groundwater flow paths. The literature review highlights the current state of knowledge on groundwater quality assessment, emphasizing the importance of integrating geophysical methods with traditional hydrogeological techniques for comprehensive site characterization. The review also discusses the factors influencing groundwater quality in urban areas, including land use practices, industrial activities, and underground storage tanks. The findings of the study reveal significant variations in groundwater quality parameters, such as pH, conductivity, and major ion concentrations, across the study area. Geophysical surveys conducted at multiple locations provide valuable insights into the subsurface hydrogeological conditions and the spatial distribution of contaminants. The results underscore the effectiveness of geophysical methods in identifying potential zones of contamination and guiding targeted remediation efforts. The discussion of findings delves into the implications of the study results for groundwater management and policy formulation in urban areas. The integration of geophysical data with hydrochemical analyses enhances our understanding of groundwater dynamics and facilitates the development of sustainable strategies for safeguarding water resources. The study also highlights the importance of community engagement and stakeholder collaboration in promoting groundwater protection and conservation efforts. In conclusion, the assessment of groundwater quality in urban areas using geophysical methods offers a valuable approach for addressing the complex challenges associated with urban water resources management. By combining geophysical surveys with hydrogeological investigations, this study contributes to the advancement of innovative techniques for groundwater characterization and monitoring. The findings underscore the critical role of geophysics in enhancing our ability to assess and manage groundwater quality in urban environments, ultimately supporting sustainable water resource management practices.
