Integrated approach to choosing suitable areas for the realization of productive wells in rural areas of sub-Saharan Africa

Comprehensive geological, hydrogeological and hydrogeochemical investigations were carried out in the
south of Hodh El Chargui (southeast Mauritania). Obtaining a hydrogeological conceptual model is crucial for
groundwater resources development and management. This is especially true in developing countries and in the
rural areas of sub-Saharan Africa. The chosen areas are represented by lithologies referring to a long geological time
frame, dating from the Upper Neoproterozoic to the Quaternary age. We developed a methodology in order to
identify sites that were suitable for the realization of productive, protected and correct wells to supply safe water to
the rural community. A multicriteria approach to studying hydrogeology was used in the project area. In order to
identify some main areas in which to carry out pilot interventions, criteria relating to water accessibility and
availability, and to hydrogeological and water quality, were considered. Moreover, during the project, it was
possible to transfer know-how and hand over responsibilities to the local population and bodies.
