Assessment of Groundwater Quality and Its Impact on Human Health in an Urban Area

Thesis Abstract

Abstract
Groundwater is a vital resource that supports various human activities, including drinking water supply and agricultural irrigation. However, its quality can be compromised by various anthropogenic activities, leading to potential health risks for the urban population dependent on it. This thesis aims to assess the groundwater quality in an urban area and investigate its impact on human health. The study begins with a comprehensive review of existing literature on groundwater quality assessment, human health implications, and urban water management practices. It identifies the gaps in current knowledge and sets the context for the research. The methodology chapter outlines the research design, sampling strategy, analysis techniques, and data interpretation methods employed in the study. Field investigations are conducted to collect groundwater samples from various locations within the urban area. These samples are analyzed for key parameters such as pH, turbidity, heavy metal concentrations, microbial contamination, and the presence of organic pollutants. The results are compared against relevant water quality standards to assess the extent of contamination and potential health risks associated with groundwater consumption. The findings reveal significant variations in groundwater quality across different sampling sites, with elevated levels of contaminants detected in certain areas. High concentrations of heavy metals such as lead, arsenic, and cadmium are observed, along with microbial contamination from fecal coliforms and nitrates. These pollutants pose serious health risks, including gastrointestinal illnesses, neurological disorders, and carcinogenic effects, especially for vulnerable populations such as children and the elderly. The discussion chapter critically analyzes the findings in relation to existing literature, highlighting the sources of contamination, pathways of exposure, and potential mitigation measures. The implications of poor groundwater quality on public health, environmental sustainability, and urban development are explored, emphasizing the need for effective regulatory frameworks and community engagement in water management. In conclusion, this thesis underscores the importance of regular monitoring and assessment of groundwater quality in urban areas to safeguard public health and promote sustainable water resource management. Recommendations are provided for policymakers, water authorities, and community stakeholders to address the identified challenges and improve the overall quality of groundwater for human consumption. Further research directions are also suggested to enhance our understanding of the complex interactions between groundwater quality, human health, and urban environments.
