This was grandparent’s spring fountain.
In this area, situated in the north east of Italy, you can bore a pipe into the ground and you will find Alpine spring water perfectly drinkable. I grew up thinking this was normal and that drinking water was everywhere to be found!
This phenomenon though, covers a relatively small area between the mountains and the sea.
What happens here is called “Risorgive” or resurgence waters: usually in mountainous areas the rain water disappears into the ground and then returns to the surface in the plains.
All of this depends on the type of soil the water finds.
If the ground consists of coarse material such as pebbles, gravel and even sand, and is permeable the water will infiltrate into the ground and will resurface when it finds a finer soil like silt or clay which is impermeable. It is fairly simple phenomenon but very interesting.
I like the taste of this water: it’s clean and fresh and this is what I fill my bottles with when I am in Italy: fresh water straight from the mountains. I could not think of any better water to have!
