Water is the majority component of our body, and that is why it must be replenished, having to drink between 1.5 and 2 liters a day depending on the body composition of each one.
And currently we have both tap water and bottled mineral water available, and believe it or not, there are wide differences between them, and we are not only talking about one being free and the other paid.
So the OCU wants to help you to know if it is more advisable to drink mineral water O well tap waterwhich is the best, the compositions and the differences between them.
To understand this report from the OCU, it must first be taken into account that the consumption of agua Bottled or tap water consumption is very similar among the Spanish population, although tap water has a slight advantage.

The above is also related to the province in which you are, since the question of water hardness enters here, caused by the content of lime and magnesium salts.
Depending on the hardness of the water, which varies considerably between each of the autonomous communities, the water may taste better or worse.
For example, those cities that have very hard water, such as Valencia or Mallorca, the water has a worse taste.
Then in places like the Community of Madrid, Galicia or Extremadura, the water, being soft, has a better flavor.

Question of price and sustainability
Evidently to drink Tap water is always cheaper since, according to the Ministry of Agriculture, it costs only one euro per year.
However, bottled mineral water is usually sold at €0.21 per litre, so considering that a person needs about 2 liters of water per day, they will end up spending around €150 per year on bottled water.
On the other hand, not only drinking tap water is cheaper, but also more sustainable, since the impact on the environment is less by not having containers, such as plastic mineral water bottles.
The OCU also talks about the differences between the different bottled waters, including natural mineral water, spring water or prepared water.
Natural mineral water is underground and pure in origin, and its mineral composition is constant, always the same, but periodic analyzes must be presented to demonstrate the constancy of its composition. On the other hand, spring water is groundwater, pure in origin, its composition is natural, it is not constant, it can vary and it must be analyzed once before being sold. Finally we have the prepared water, which is that of public supply, that is, bottled tap water that is usually used when there is some type of breakdown.
And the OCU answers the question, and affirms that “tap water is the best option, since it is an economical, sustainable and quality alternative”, and “its consumption should be encouraged whenever possible”.
