Assessment of Groundwater Quality in Urban Areas using Geographic Information Systems (GIS) and Remote Sensing Techniques

Thesis Abstract

Abstract
This thesis presents a comprehensive study on the assessment of groundwater quality in urban areas through the integration of Geographic Information Systems (GIS) and Remote Sensing techniques. The aim of this research is to evaluate the quality of groundwater sources in urban settings, identify potential sources of contamination, and propose strategies for effective management and protection of these vital resources. Chapter 1 provides an introduction to the research topic, outlining the background of the study, problem statement, objectives, limitations, scope, significance, structure of the thesis, and definition of key terms. The literature review in Chapter 2 covers ten key areas related to groundwater quality assessment, GIS, Remote Sensing applications, urban water management, and pollution sources. Chapter 3 details the research methodology, including data collection methods, sampling techniques, laboratory analysis procedures, GIS and Remote Sensing tools used, and statistical analysis techniques applied. The chapter also discusses the study area selection, data processing steps, and quality control measures implemented to ensure the accuracy and reliability of the findings. In Chapter 4, the findings of the study are presented and analyzed in detail. The groundwater quality parameters assessed include pH, electrical conductivity, total dissolved solids, major ions, heavy metals, and microbial contamination. Spatial distribution maps and statistical analyses are used to identify potential pollution sources, hotspots, and areas of concern within the urban groundwater system. The discussion in Chapter 4 focuses on the implications of the findings, potential risks to human health and the environment, and the effectiveness of current water management practices in urban areas. Recommendations for policy interventions, source protection measures, and sustainable groundwater management strategies are proposed based on the study outcomes. Chapter 5 concludes the thesis by summarizing the key findings, discussing the implications for future research and policy development, and highlighting the importance of integrating GIS and Remote Sensing techniques in groundwater quality assessment in urban areas. The study contributes valuable insights to the field of environmental science and provides a foundation for further research on sustainable water resource management in urban environments. Overall, this thesis underscores the critical role of GIS and Remote Sensing technologies in enhancing our understanding of groundwater quality dynamics in urban areas and emphasizes the need for proactive measures to safeguard these valuable resources for current and future generations.
