Expiration dates printed on water bottles are for the bottle material, not the water itself. Water has no expiry date. After a while, when the expiration date is over, the plastic will start coming out of the bottle into the liquid. Will do, which is closed in this bottle.
Water never goes bad. If water is sealed in a container for ten thousand years, where the particles of the container do not mix with the water, then the water will always be fresh and fresh without any change in taste. Putting a freshness date on a bottle of water makes as much sense as an expiration date on sugar or salt, i.e. salt and sugar have the same shelf life if they are protected from the effects of canter.
Although the water, in itself, does not spoil, the plastic bottle that contains it does "expire" and eventually begins to mix chemicals with the water. Bottles for water and other beverages are now manufactured from PET material. Polyethylene terephthalate, also known as PET, is a clean, strong, lightweight, and 100% recyclable plastic. Although it is generally considered a "safe" plastic, it contains no plastic. The toxic element is not BPA, but in the presence of heat and past the expiration date, it can leach antimony, a toxic metalloid, from food and beverages into water or beverages, which can have some harmful effects. And depending on the amount of plastic leaching, these effects can occur.
Now, this won't necessarily make the water toxic, but it can make it taste a little less than the "natural mountain spring water" that mineral water companies often claim. If consumers contact beverage companies to complain that the water they bought years ago has a bad taste and odor, bottlers can indicate that they should not drink it by the expiration date. It's his fault.
