?What is a Mineral
To be a mineral a substance must meet five requirements:
Is Water a Mineral?
If we compare the properties of water to the five requirements of the mineral definition we find that it fails to qualify as a mineral. Water is a liquid so it does not meet requirement #3 - being a solid.
However, at temperatures below 32 degrees Fahrenheit or 0 degrees Celsius water becomes the solid material that we call "ice".
Is Ice a Mineral?
A natural snowflake would be considered to be a mineral because it forms naturally in Earth's atmosphere. However an ice cube made in a refrigerator would not be considered a mineral because it was produced by the actions of people.
So, ice is a mineral when it forms naturally but it is not a mineral when people play a role in producing it.
What is Mineral Water?
These dissolved substances occur in the water because while the water was in the ground it came into contact withmineral and non-mineral materials. Some of those materials were soluble and were dissolved by the water.
To be sold as a "mineral water" a liquid must be water, taken from a natural source, and containat least 250 parts per million total dissolved solids - that occur naturally in the water.
Natural mineral waters are found at many locations worldwide and vary widely in composition. Under some circumstancesthe dissolved materials in the water would be considered to be "impurities". Under other circumstances these waters arebottled and sold to people who believe that the dissolved "minerals" might provide a health benefit.
These health benefits are often unproven and many natural waters contain dissolved materials that produce undesirable or even poisonous effects if consumed by people or animals.
