Un test of Altroconsumo Published yesterday on the safety of mineral water, it detected anything but trrability of pollution traces in what we drink. Let’s imagine that I get from pristine sources, fresh and pure, panacea of all our natural evil and detoxifying. Instead. Here’s what you need to know to choose what to drink.
Mineral water: what the test on 21 brands says
It is not always as pure as you think. According to what emerged from the Altroconsumo test carried out on 21 brands of natural mineral water, reality is not very comforting. Even bottle water, in fact, “is not unscathed by the effects of environmental pollution that now affects the entire ecosystem”, communicates Altroconsumo.

Disturbing results
Here are the results of the comparison test on 21 natural mineral water brands from different areas of Italy (and one from the French Alps). The full version can be found at the link https://www.altroconsumo.it/timentazione/acqua-in-bottiglia/Comma.
Many brands have obtained one assessment only sufficient for the parameter of environmental pollutants. Six have been rejected with insufficient judgment.
The ranking
Only three brands have proven completely free from TFA. Tripleacetic acid It is part of the PFAS family, the synthetic molecules also called “eternal pollutants” used in large quantities in different industrial sectors.
Blues Sant’Antonio (Eurospin) It wins the best test of the test and better purchase, with one of the lowest cost (0.17 euros/liter). Conad Valpurawhich also obtains the recognition of best purchase. San Benedetto Eco Green Benedicta, appreciated for the quality and environmental impact contained.
All types to know
According to what suggested by the magazine Altroconsumo“It is the amount of mineral salts present in natural mineral water that determines its classification and intended use”. Here are all the differences and what use they are intended.
Minimally mineralized
The minimally mineralized one is that with a content in mineral salts, calculated as fixed residue at 180 ° C, not exceeding 50 mg/l. It is light water, which stimulates diuresis, indicated for the preparation of milk powder and other foods for children.
Oligomineral
The oligomineral or slightly mineralized water has a content of mineral salts not exceeding 500 mg/l. This also favors diuresis and is indicated in Hyposodic diets Since it is generally a low sodium water.
Mineral
In the mineral, or mediaomine, the Content of mineral salts has a value between 500 and 1500 mg/l. It is very useful in summer or during the practice of sports activities, because it allows you to reintegrate liquids and mineral salts lost with sweating.
Rich in mineral salts
In the rich type of mineral salts the fixed residue at 180 ° C is greater than 1500 mg/l. It is, therefore, a type with a high tenor in mineral salts, generally considered therapeutic, whose consumption is preferable to take place Only on medical indication.
Where does the natural mineral come from?
According to the provisions of the law, the natural mineral comes from one sourcenatural or not, which must be kept sheltered from any risk of pollution. Natural mineral waters are therefore distinguished from potable waters For the original purityfor the tenor in mineral salts, trace elements and other constituents and, possibly, for their effects on health.
Natural mineral waters they cannot be subjected to any pruning treatmentnor can they be subject to operations that modify their composition in those essential components that give the water itself its properties.
Only this type of water can be sold
Can be marketed as natural mineral waters only the waters that have obtained the recognition of their status by the Ministry of Health.
What contains natural mineral water contains
Natural mineral water It mainly contains mineral salts. The content in mineral salts of natural mineral water represents its fixed residue, which is determined at a temperature of 180 ° C. The fixed residue of a natural mineral water also determines its classification. For example, water with low fixed residue is classified as minimally mineralized or oligomineral, while a high fixed residue water is classified, for example, as rich in mineral salts.
PH, nitrates and sodium
The pH of natural mineral water can generally vary Between 6.5 and 8.0 and is determined by the ions dissolved in it.
Among the elements that can be present in mineral water there are, for example, i nitrates. These are naturally present in natural mineral waters in small quantities, But one high quantity can indicate a contamination.
The sodium It is generally present in small quantities In natural mineral waters, while the waters with a high fixed residue can represent in some cases an interesting source of calcium, which can integrate the one taken with the diet.
Subsal substances such as i can also be present in the waters fluorides or metals such as arsenic or manganese. All trace elements present in natural mineral waters because derived from the ground from which they flow. However, in some cases they may be present in quantities that can put health at risk.
