Mapping the groundwater vulnerability for pollution at the pan African scale

We mapped the pan-African intrinsic and specific vulnerability of groundwater systems towards pollution. We compiled the most recent continental scale information on soil, land use, geology, hydrogeology and climate in a Geographical Information System (GIS) at the resolution of 15kmx15km and the 1:60,000,000 scale and implemented an indicator vulnerability model based on the DRASTIC method. The intrinsic vulnerability map reveals that groundwater is highly vulnerable in Central, West and some areas of North Africa, where the watertable is very low.
