Size
edit"Containing an estimated 150,000 km³ of groundwater,[2] the significance of the NSAS as a potential water resource for future development programs in these countries cannot be overstated. Recently the Great Man-made River Project (GMMR) in Libya began extracting massive amounts of water from this aquifer, removing an estimated 6.5 million m³ per day." -This would seem to indicate that, assuming that the removal rate stays the same, and that all the groundwater is available for extraction. This water supply can last no longer than about 63 years. (150 000 000 000 / 6 500 000) / 365 = 63.2 years Likely it will be depleted before that time due to increased demand and extraction inefficiencies.Greenknight21 18:44, 1 November 2007 (UTC)
- 1 km³ = 1000 * 1000 * 1000 m³. The correct calculation is is 63 thousand years. Pavel Vozenilek (talk) 21:48, 9 September 2008 (UTC)
I changed the article to use km³ instead of m³. It should now be obvious that there's no danger of running out of water any time soon. --Dante Alighieri | Talk 17:23, 17 October 2008 (UTC)
- 150000 km³ would mean that it is 2000 times bigger than Lake Chad. Something is wrong with these figures. Probably the size is 150 km³ (a lot of water anyway). --79.147.125.195 (talk) 10:25, 5 November 2014 (UTC)
Meteoric origin
editRemoved Dubious tag from "meteoric origin," also added a reference. In geosciences "meteoric" refers to anything coming from the sky, e.g. precipitation. SReynhout (talk) 14:51, 31 March 2009 (UTC)
Span of Nubian Sandstone Aquifer System
editMight be worth adding to article.
Ancient reservoir of water below the Israeli Negev desert is a part of Nubian Sandstone Aquifer System.
