This book specializes in groundwater monitoring and environmental impact assessments. It has revealed the groundwater pollution evaluation, remediation and radiological risk assessments which represent one of the main activities. The effort in these fields was clearly noticed due to the presence of necessary scientific contributions in groundwater monitoring, mapping the contamination channels, remediation of high radiotoxicity risks level, decontaminating of highly radioactive zones and building materials. The excellence of these book has provided a baseline for civil engineers and water resources managements on safer areas to drill boreholes for quality and consumable groundwater-based drinking in basement terrain.
