Abstract

Summary

This study in South-East Senegal addresses the urgent need for sustainable groundwater management in a crystalline basement rock area facing climatic pressures, anthropogenic activities, and geogenic contamination (notably uranium). Integrating electrical resistivity tomography (ERT) and transient electromagnetic (TEM) methods, the research mapped subsurface resistivity to identify potential water-bearing formations in Saraya and Badioula. ERT revealed localized groundwater potential in Saraya with concerning uranium levels near the existing water tower. In contrast, Badioula showed a more extensive shallow aquifer with promising potential, further supported by TEM data indicating a multi-layered structure. Groundwater chemistry analysis confirmed the uranium contamination issue. The findings from these geophysical surveys are being used to develop hydrological models to inform sustainable abstraction strategies, particularly focusing on the potential of the Badioula aquifer to supply the wider area. The project also included capacity building initiatives for local students and communities.
