Can Bottled Water Go Bad?

Can Bottled Water Go Bad - puricare

When you buy a pack of bottled water, you would often see an expiration date on the plastic wrapping.

The main reason is not because water really has an expiry date, but rather – printing an expiration date has become an industry standard for bottled water manufacturers across several countries. However, this legislation was subsequently modified, and several nations’ water not needing manufacturers to include an expiration date on bottled water.

However, it’s usually not a smart idea to drink water straight out of plastic bottles that are more than a year past their expiration date, not because the water is no longer edible, but because plastic may leach chemicals into the water over time and pollute it with antimony and bisphenol A (BPA).


One Big Misconception

It is crucial to realise that water within bottles does not go bad on its own.

The use of “expiry dates” is not due simply to bottled water’s status as a consumable or the machinery that a plant uses, according to some market-players.

The International Bottle Water Association maintains that the dates on the bottles are only used to facilitate stock rotation in retail outlets, and that there is no scientific evidence supporting the need for expiry dates on bottled water.

Manufacturers also claim that the presence of expiration dates is a residual feature left over from bottling equipment used to produce sodas and juices with expiry dates, which do have them.


Why Does My Water Flavour Changes?

Over time, water in its natural state may acquire a stale flavor as a result of carbon dioxide in the air reacting with the water and making it somewhat more acidic.

Carbonated water may lose its fizz as the gas dissipates from the liquid over time, causing flavor to fluctuate.

Although these types of water might have a strange flavor, they are generally deemed safe to consume.


Common Causes For Contamination

(1) Plastic Can Begin Leaking Antimony

Water stored in plastic bottles has been linked to the risk of polluting the water with potentially harmful compounds such as antimony. Within 5 days, when exposed to 75 degrees Celsius, the plastic may begin leaking antimony, a carcinogen, within 5 days.

Temperatures this high are certainly difficult to reach, but they are not uncommon in areas exposed to direct sunlight throughout the summer. It is probably not a good idea to leave water in cars parked in the sun.


(2) BPA Containers – Contamination During Bottling

BPA may leach from BPA containers during manufacture, as opposed to simply breaking down into smaller fractions. When food or liquids are put in the container, part of it breaks free and combines with the contents.

During the course of bottling and storage, your water may be tainted with bisphenol A (BPA). BPA is metabolized to bisphenol-A-glucuronide after entering your body and is eliminated through urine.

BPA-containing plastics are now widely utilized in food containers, baby bottles, and other goods because they are inexpensive to manufacture.

The following are examples of BPA-containing consumer goods:

  • Food in plastic jars
  • Toiletry Items
  • Household electronics
  • Lenses for eyeglasses
  • Sports equipment
  • Sealants for dental fillings


(3) Contamination of The Bottle Opening

When one drinks straight from the bottle and then touches the bottle’s opening (which may be tainted), there’s a significant risk of contamination.

Bacteria in your mouth may flow into the bottle and spread. Mildew can grow rapidly in moist conditions, and it can contaminate water in as little as 15 minutes under ideal circumstances.


Handling Opened Bottles

To be honest, bottled water has a limited lifespan once it is opened – due to exposure to the environment.

The longer the bottle is kept tightly sealed and refrigerated, the better. Bottled water that has been properly frozen can stay good for up to a week after opening.



It’s worth noting that a plastic taste in the water is not enough to accuse the water of being harmful, and that the lack of such an indication is insufficient to disprove pollution.

Bottled water should not be placed in direct sunlight or any other area where there is a lot of heat (which can cause pollution to occur). Bottled water should be consumed within two weeks of opening to avoid bacterial or algae growth.

If there is any uncertainty regarding the flavour or smell of water in a confined, it is always recommended to boil it to make it safer for you and your family.
