This lecture concludes the discussion on groundwater exploration with a focus on pollution-related issues. It emphasizes the importance of detecting, monitoring, and controlling groundwater pollution, which involves understanding pollutant transport, attenuation, and the hydrogeological environment. Evaluations for safe waste disposal sites consider factors such as mineral composition, permeability, and groundwater quality, with an emphasis on low permeability units that can act as barriers to pollutant spread. Detailed hydrogeological assessments, including flow modelling and site characterization, are crucial for identifying safe waste repositories and ensuring environmental protection. Finally, comprehensive site investigations are necessary to confirm the suitability of sites for waste disposal or remediation, involving techniques such as geophysical methods, tracer tests, and hydrogeochemical analysis.
