Aquifers are important fresh water resources for drinking, agriculture, Industry and supporting aquatic ecosystems all over the world. However, due to excessive exploitation, contamination and climatic changes, there has been depletion with great effects on the groundwater stock globally hence insecurity of water. Solving these problems calls for creativity and one such tool has been discovered through the application of Geographic Information System also referred to as GIS. This chapter looks at the functionality of the GIS technology on the restoration and management of groundwater. GIS again makes it possible to integrate topographic, geologic, land use, precipitation and human activity maps to find recharging areas, measure water table fluctuations, evaluate contamination threats, and apply proper management techniques. The chapter also demonstrates how GIS functions with remote sensing, hydrological modelling, and geo-statistics for improving the efficiency of the restoration initiatives for groundwater. Some of the uses of GIS covered during discourse include; enhancing effectiveness of artificial recharging, depicting areas prone to contamination and appraising decision making on management of aquifer. It also discusses advances in GIS technologies and practice including the incorporation of artificial intelligent use of real-time data processing, and details challenges including data access and technical skills. Finally, this chapter emphasize that GIS has a significant function in the sustainable use of the groundwater resources.
