Long description: The upper Garonne valley is the driest area in south-west France. The oxygen 18 isotope (18O) and the ionic charge of surface and ground water (The isotopic signature and ionic conductivity of river water was distinctly different from groundwater) were used to estimate the water source for the Garonne River and phreatic subsurface water. 18O signatures and conductivity in the Garonne River indicated that the predominant water source was high altitude surface runoff from the Pyrenees. Tributary inputs had little effect on isotopic identity, but had a small effect on the conductivity. The combination of 18O signatures and ionic conductivity appears to be effective for determining water sources on geographic scales.
