Water, in general, does not expire, but if you have ever bought a pack of bottled water, you may have noticed there is an expiration date printed on the packaged drinking water. This might make you wonder if the water is safe to drink after it surpasses the expiration date.
Let’s dive into knowing the water you drink and understand whether it can be perishable.
Does the tap water expire?
It is completely safe to store and consume tap water for up to 6 months without the slightest risk of adverse side effects, especially when it has been stored properly. The only effect shows in tap water is a change in flavour with time because the tap water is carbonated that can become flat as the gas slowly escapes from the liquid.
Carbon dioxide in the air mixes with the water, making the regular water slightly more acidic. Even the regular water tends to develop a stale taste over time due to this. However, these types of water may develop an off taste over time; they are still considered safe to drink for up to 6 months.
To ensure keeping water from getting contaminated, it must be stored in cleaned and sanitized food-grade water containers and label them with the filling date and indicate that it contains drinking water. Make sure you store these containers in a dry, cold and dark place for six months.
Does bottled water go bad?
Like discussed before, water, in general, does not have an expiration date however bottled drinking water often has it. A long time ago, a law was passed in New Jersey according to which, it became necessary for food and water companies to have an expiration date of 2 years or less on each product. It became essential to print an expiration date on water bottles even if technically water does not expire. Later on, the law changed, but it is still advisable not to drink bottled water if they are older than six months.
Bottled drinking water comes in plastic water bottles, and plastic releases BPA (bisphenol), antimony and other chemicals which contaminates the water and makes it harmful for human consumption. Even regular consumption of water from these plastic bottles can lead to harmful health effects like poor gut health, lowered immunity and disturbed respiratory function.
How should you be storing your water?
More often than not, the way you store your water tells a lot about how long will it remain to be safe for consumption. Store bottled drinking water properly; it will help prevent bacterial growth and reduce the risk of harmful effects like nausea, diarrhoea, stomach ache and vomiting.
Primarily, warm temperatures stimulate bacterial growth and increase the release of harmful plastic chemicals into the water. This is the reason why keeping bottled water out of direct sunlight in a cool place can help promote proper water safety and reduce the risk of adverse health effects.
Plastic bottles are also quite porous, so it is best to store them away from household cleaning supplies and chemicals. In case you notice that your bottled drinking water has developed an odd taste or odour, you must boil it before you consume it or completely discard it.
The bottom line
Tap water or water coming from your specific sources are safe to be stored for up to six months. However, due to certain chemicals found in plastic that leach into bottled water after some time, it is not safe to consume it exceeds the expiration date and could potentially cause damage to your overall health. Therefore, it is possibly the best option to avoid drinking water from such water bottles that are far past their expiration date. And another important aspect is that you must always check the expiration date of your packaged drinking water in order to ensure your safety. Additionally, practice proper storage techniques that can help reduce the risk of adverse effects caused by long-stored water and ensure that the water you are consuming is safe.
