Bottled or tap water? What you need to know to choose

Is it better to drink bottled water or tap water? To choose the best alternative to your needs, you need to be informed.

One is an eco-friendly alternative. The other, a choice of taste. When it comes to choosing which water to drink, we are not divided only between fans of the sparkling or the natural (leaving aside those who, according to the Christian Democrats , choose the effervescent or slightly sparkling).choosing the best alternative requires informationThe bottled water party often collides with that of tap water . The truth is that, although it is always and only liquid composed of two molecules of hydrogen and one of oxygen, there is a lot of ignorance around water. According to a research by Irsa, the institute of the National Research Center (CNR) responsible for controlling water quality, Italy ranks fifth in Europe for tap water quality. But the Italians are the first in the Old Continent for the consumption of bottled water. How is it possible? Perhaps too many clichés and little information. Here’s how to consciously choose whether to embrace the faucet cause or stick to the bottle.

The regulations

What does the law say? Mineral and aqueduct waters are regulated by two different decrees. The mayor’s water is governed by Legislative Decree 31/2001, which transposes the European Directive 98/83 / EC . This Decree establishes the maximum values ​​of the substances that can be dissolved in the water and provides the sanitization parameters (presence of chlorine) capable of guaranteeing that the water arrives from the aqueduct to the point of use free of contamination . The local health authorities will check that everything is in order . It is also true that not all the waters that flow from the tap are the same. Often the concentration of some elements that compose them can vary according to the characteristics of the territory in which they are born.

Bottled mineral waters are governed by the Ministerial Decree of 10 February 2015 . Many of the strictly regulated parameters for tap water have no limits for bottled water. So the real paradox is that, analyzing some indices, some mineral waters would not be drinkable. ” This is mainly due to” technological “reasons related to transport in pipes and not to human health – explains Giorgio Temporelli, expert in hygiene, legislation and technologies for water treatment –Parameters such as calcium, magnesium, sulphates, hardness and pH can be responsible for the formation of encrustations and occlusions of the pipes, on the contrary chlorides can favor corrosion, aspects that must therefore be regulated for the water conducted while there are no limit values ​​for those minerals “.

The path of bottled water

From source to table, bottled water goes a long way. Between transport and storage, this food can also arrive at its destination altered due to the reactions of the plastic bottle to unfavorable environmental conditions such as light and heat. For this reason, the manufacturers also indicate the storage conditions on the labels , but it is often difficult to respect them. The transport of bottled water to supermarkets is mostly done by road: many trucks travel hundreds of kilometers up and down Italy, even in the hottest months, stressing the containers. Once arrived at its destination, sometimes this water can also give off unpleasant odors, the result of the corruption of the PET with which the package is made. Furthermore,the cost of bottled water weighs on the environment . In addition to the emissions produced by the vehicles that carry the pallets around Italy, there is also the problem of plastic waste to be managed . 700 tons of it end up in the Mediterranean every year. It is estimated that by 2050 there will be more plastics than fish.

The Italian green alternative

But there is a green alternative: tap water . The high quality of the Italian one is given by the presence of underground sources scattered throughout the country . To this capillarity (which shortens the transport maneuvers) corresponds the safety of the water systems and the control system guaranteed by the Als and by the companies that manage the water services. For this reason, the mayor’s water can truly be defined as 0 km: always fresh, from the tap directly to the glass.

When and why to treat tap water

In short, tap water has many arrows in its bow: it is healthy, it is green and it is already in your home.healthiness is guaranteed up to the counter at home, but then the pipes come into playThere was a time when filter jugs and tap purifiers invaded our homes, convinced that only in this way could we obtain a product at least similar to bottled water. According to Culligan, an international reference company in the world of water treatment, despite the fact that the tap water in our country is excellent, it can be made even better and healthier. As? Through filtration for example. First of all, remember that the healthiness of the mayor’s water is guaranteed right up to the home meter. Crossing the walls of the house through pipes that are not always very new, the liquid can become contaminated with lead and ferrobacteria. Another unwanted flavor is the chlorine flavor, which for some may be unbearable. For this reason, depending on where you are, the age of the building in which you live and the taste we perceive in the glass, deciding to treat and filter tap water can be a way to go to abandon the water in bottle. From activated carbon filters to reverse osmosis filters, there is no shortage of methods. But pay attention to the maintenance of the devices : it must be as accurate as possible.

And sparkling water?

There is a category of consumers who are unwilling to compromise for anything or anyone: sparkling water lovers. From those who go crazy for the powerful San Pellegrino and those who for nothing in the world would change their Nepi, they are the most difficult to convert to the most eco-friendly world of drinking water. Maybe a fridge could be the solution. Perhaps.
