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.

Statement: The purpose of this work is to help develop the understanding of the hydrogeological processes and assess the resilience of these important resources to short-term inter-annual variability in the contrasting climates found in West Africa today. This study represents a first step towards quantifying the mean residence times (MRT) of groundwater pumped from unstressed shallow rural groundwater supplies in West Africa, by comparing residence times across regions with contrasting rainfall, while controlling for other important factors such as geology, unsaturated zone thickness, rates of abstraction, borehole construction and surface-water.
