Northern Ghana hydrogeological assessment project

Groundwater is the most viable source of potable water in northern Ghana, West Africa, especially for the 80% rural inhabitants. Millions of dollars have been expended there on groundwater-based water supply infrastructures, and these expenditures are likely to continue in coming decades. The Hydrogeological Assessment Project (HAP) of the Northern Regions of Ghana was initiated to provide scientific background for groundwater-based supply projects as well as resource management. This paper summarizes the technical approaches and results to date, which include a compilation of available data, targeted field data collection, and the development of a regional hydrogeological synthesis.
