Does the Sahara desert have groundwater?

We'll drink to that: Massive underground reserves of water found in some of Africa's driest areas - including the Sahara Desert ... read more

Groundwater is everywhere if one is willing to drill deep enough and tolerate water that migrates into the well very slowly and might be highly mineralized. The Sahara is one of the better sources. It was temperate in the last ice age and some of its alluvial basins no longer have any natural drainage. Their fossil water is trapped. read more

‘In northern Nigeria there have been groundwater irrigation projects that have failed because of the rising cost of fuel - a major factor in drilling costs - and distribution difficulties.’ The researchers say some of the largest deposits are in the driest areas of Africa in and around the Sahara, but they are deep - at 100 to 250 meters below ground level. read more

Due to changes in climate that have turned the Sahara into a desert over centuries many of the aquifers underneath were last filled with water over 5,000 years ago. The scientists collated their information from existing hydro-geological maps from national governments as well as 283 aquifer studies. read more
