To be able to strike rockface and have water gush out as the Bible seems to describe, and also to have perpetually flowing springs, you need to be in a limestone region where rainfall can penetrate and ‘saturate’ the rock, dissolve the rock to create karstic channels, and feed local underground aquifers which maintain ‘pressure’ to the springs. Without these natural phenomena, you need to assume a completely spectacular miracle. Let’s not go down the path of that debate again :-/ … but let me just note here that there is a great reservoir of ‘fossil’ water under the Karkom Plateau.
'Drinking Water from Under the Arava" from Teva Ha-Dvarim, Dec 2001, no. 74, p. 20.
“An underground reservoir of water of good quality has been found recently under Nahal Karkom, south of the Ramon Crater. The reservoir is not connected to any of the great underground reservoirs found in the Negev 20 years ago. The reservoir is 1000 m below the surface and it contains high quality water — the concentration of salts in the water is similar to that of the Kinneret. / This is good news for the settlements in the Negev and Southern Arava Valley, whose locations far from Israel’s water sources has created difficulties in water supplies. According to estimates made by Israel’s water company, Mekorot, it will be possible to take advantage of the Karkom area for drilling wells of great depth for a long period of time. The water can be transported to the settlements in the Arava and possibly even Mizpe Ramon. At the moment the town gets its water from the national water carrier, and thus the people of Mizpe Ramon are drinking water from the Kinneret, located hundreds of kilometers distant. / So far there is no exact estimate of the amount of water in the [Karkom] reservoir but it will be possible to pump a steady amount of water of several million cubic meters every year, approximately the amount used by Eilat, which gets its water from desalination plants next to the town. / The use of the Karkom reservoir will eventually be used up because it is a one-time reservoir to which water does not penetrate. It appears that water flowed into it in early periods from the edges of the Ramon Crater and sank down to a layer of sand, From here the water continues to move southwards in the direction of the Arava and there they are exploited. The problem is that the water pumped in the Arava is very salty and of a poor quality.”
