"The knowledge about groundwater flow conditions within the Southeastern Taoudeni Basin Aquifer shared by Burkina Faso and Mali is relatively limited. The paper provides a transboundary synthesis using water and carbon isotopes in conjunction with hydrogeological and hydrochemical data. The objectives are to improve the conceptual model of groundwater recharge and to assess the changes in the aquifer due to water abstraction and recent climate changes. The carbon-14 activity measured on the TDIC varies between 0.3 and 122 pmC. All groundwater samples have stable isotope compositions in the range of the present day regional meteoric water line which suggests that the sampled groundwater was not significantly affected by evaporation during recharge. The whole dataset points out the very low renewability of the resource and a strong anthropogenic contamination of the shallowest horizons." .
