Water quality and geochemical characterisation

Water geochemistry involves studying the water from a physical and chemical point of view. The water found naturally is a rather diluted saline solution; therefore, the rain water (or melted snow water) can be seen as an extreme example of poorly mineralised water (so much so that it could almost be considered distilled), while sea water represents an extreme case of highly mineralised water. All the other water found naturally falls within these two extremes.
The dissolved salt content in the water is caused by the different elements which the water encounters during its journey, starting from the open air and then continuing underground, where it filters down until it re-emerges at the springs. Along the underground section, the water comes into contact with various soils and rocks, causing a chemical reaction with their mineral content. Through this contact, the water dissolves the minerals, enriching itself with substances and acquiring a special mineralisation. These substances form the water’s ion content.
