Assessment of groundwater quality in a coastal region affected by saltwater intrusion

Thesis Abstract

**Abstract
** This thesis investigates the groundwater quality in a coastal region impacted by saltwater intrusion, focusing on assessing the extent of contamination and its implications on water resources. Groundwater is a vital resource for various purposes, including drinking, agriculture, and industrial activities. However, coastal areas are particularly vulnerable to saltwater intrusion due to factors such as sea-level rise, over-extraction of groundwater, and changes in hydrological conditions. The study begins with a comprehensive introduction to the problem, highlighting the significance of understanding groundwater quality in coastal regions and the potential risks associated with saltwater intrusion. The background of the study provides context on the geological and hydrological characteristics of the study area, emphasizing the importance of maintaining freshwater resources in the face of increasing salinization. A detailed literature review in Chapter Two explores existing research on saltwater intrusion, groundwater quality assessment methods, and mitigation strategies. The review synthesizes key findings from previous studies to provide a robust foundation for the current research. Chapter Three outlines the research methodology, including data collection techniques, sampling procedures, laboratory analysis methods, and data interpretation approaches. The methodology section describes how groundwater samples were collected from various monitoring wells across the coastal region and analyzed for key water quality parameters. In Chapter Four, the findings of the groundwater quality assessment are presented and discussed in detail. The results reveal the extent of saltwater intrusion, variations in water quality parameters, and potential sources of contamination. The discussion section examines the implications of these findings on water resource management and suggests potential strategies for mitigating saltwater intrusion effects. Finally, Chapter Five summarizes the key findings of the study and provides conclusions drawn from the analysis of groundwater quality in the coastal region affected by saltwater intrusion. The thesis concludes with recommendations for future research directions and practical measures to safeguard groundwater resources in similar coastal environments. Overall, this thesis contributes valuable insights into the assessment of groundwater quality in coastal regions impacted by saltwater intrusion, highlighting the importance of sustainable water management practices to ensure the availability of safe and reliable water resources for present and future generations.
