What is the real significance of "mineral" water compared to tap water, in terms of health?

All drinking water, including tap water and water that is called “mineral water”
basically includes the same salts in compositions and concentrations that depend on
the environment where the water flows. Water is the “universal solvent” and carries
different minerals washed away from the rocks with which it comes into contact in its
natural environment, and this is the factor that determines its natural quality. About
two-thirds of the planet is covered in water, which is called the “hydrosphere” and
describes the combined mass of water found on, under and over the earth’s surface.
The hydrosphere is one of the four spheres around the earth.

Of all the componentsof the hydrosphere, the water that is fit for human use is surface water (on the
surface of the continents) and groundwater (water that has seeped down from the
surface and is the source of water in springs and wells). In Israel, a random test of
mineral concentrations in the wells subject to the Ministry of Health’s supervision and
their comparison with the mineral concentrations in “mineral” water indicates that the
concentrations are similar, and that both kinds of water provide a tiny amount of the
quantity the body requires compared to the amount of minerals we get from our food.
