Nowadays mankind is facing some fundamental problems: quality water and food, as well as sustainable energy sources. But given the topic of this article, we will only deal with water.

Natural water and especially natural mineral water is a complex mixture of mineral salts and when choosing a clean and healthy water we have to consider several components: the type of water, source, minerals and the amount of minerals in a litre of water, nitrates or other harmful chemical substances, pH etc.

Total mineralisation (TDS) versus purity.

First of all we must mention that the water exhibits its preventive and healing, nutritional and feeding properties, if not physically or chemically treated.

Any atropic treatment of the water results in major or subtle changes in its quality on which life, health or disease actually depend on.

Hardly controllable channels of communication erroneously promote various methods of water treatment, filtration-microfiltration, ultrafiltration, reverse osmosis, chlorination, ozonation etc, which change the natural balance of water.

The water that is demineralised and then “rebuilt” by selective remineralisation is not natural and is likely to have adverse effects on health.

The example we are dealing with today is reverse osmosis, a filtration process that uses membranes having extremely small pores that retain 99% of the organic particles and microorganisms and about 95% of ionic compounds.

The resulted water is nutritionally destructured, with zero biological value.

The method used for the promotion of such water relies on some TDS (total dissolved solids) testing devices, and the promoters of this method intentionally or not, out of obvious ignorance, “confuse” PURITY with total mineralisation (TDS). It must be said from the beginning that most of the tested water fails this test, because water has mineral load, which is absolutely normal.

Purity does not mean the absence of minerals in water. The water purity indicators refer to the content of nitrates and nitrites, oxidability, zinc, phenol, tensioactive substances,  tetrachloroethene and trichloroethene, etc. None of these substances can be determined using that TDS measuring device.

As total mineralisation is concerned natural mineral water cannot be compared to the network water, its load of healthy inorganic salts being much higher. This is why the TDS measuring device shows much higher values for the mineral water compared to the network water.

Therefore, AQUA recommends you to read additional materials on water, to look for information provided by specialists, by scientific studies. Bottled mineral water is subject to a lot of tests and it is certified by specialists in all areas as a healthy choice for anyone who follows the specific instructions and recommendations.
