Water may come from prehistory to save Sicily from drought: an underground basin of fresh and brackish water of 17 billion cubic meters has been found, between 800 and 2100m deep under the Iblei Mountains

I haven’t heard this news anywhere, it seems interesting:

"Possibility of using deep water resources to mitigate the growing water shortage"The National Institute of Geophysics and Volcanology introduced the news in this way

A huge reserve of water in the deep and ancient heart of Sicily, thanks to a process that began about 6 million years ago. A large underground body of fresh and brackish water preserved in a deep aquifer between 800 and 2100 meters deep under the Iblei Mountains, in southern Sicily. The volume of stored water estimated by scholars is equal to about 17.3 cubic kilometers, or 17 billion cubic meters that from prehistory could save the Sicily of the present and the future: water, therefore, with varying degrees of salinity, not directly usable for human consumption: in fact, as the depth increases, the degree of salinity of the water would increase

(I don’t understand why the article says “between 700 and 2500 meters deep”the paper clearly says “between 800 and 2100 m”)
