Inorganic and tracer data for groundwaters collected in Nigeria and Mali in 2010 as part of a project to look at residence times of shallow groundwater in West Africa and to assess the implications for hydrogeology and resilience to climate change.

The data includes field chemistry, major and minor ions (ICP-MS and IC), nutrients (DOC), and tracers (Tritium, CFCs, SF6, δ18O, δ2H, δ13CDIC) collected in Nigeria and Mali in 2010. There is a brief description of the source, depth and completion date of the borehole, type of pump, estimated village population and estimated rainfall. Work funded by UK Department for International Development.
