Among such a large number of very strong photos on the Christmas theme it is very nice to see a mention of my account! Thank you!
I congratulate everyone who took part and everyone who won that competition!

Today, I began to dig deep into my photo archive to those times when I found myself next to a mineral water source.

You know when you are at the counter in a supermarket it is very easy to talk about the mineralization of water reading the description of the composition of mineral water on the label which often is just a marketing ploy and has nothing to do with the natural enrichment of water with microelements.

But in fact any natural underground source of water is mineral since passing through layers of clay or other geological rocks namely through blue clay passes an aquifer feeding the source shown in my photo, which means that it contains a lot of salts. for example, silicon.

Many springs are enriched with gases hydrogen sulfide and radon therefore they can be both beneficial and harmful, since radon is unsafe in large quantities and in a confined space since it is a radioactive gas.

And hydrogen sulfide is something that not everyone will be happy to accept since the smell of rotten eggs does not evaporate from the water for a long time.

Today even tap water can be called mineral judging by the amount of sediment in the kettle after boiling water.

So, here is my version of a mineral spring.
