How does water expire

For this reason, many bottled water manufacturers recommend that you keep bottled water for no longer than two years. There are some issues that might make old bottled water less ideal for drinking.

The first major issue, and perhaps the most widely known one, is caused by the chemicals in the bottle itself. Because, as stated by the FDA, the water itself will not expire. So, any potential safety issues will be caused by the bottle. Plastic water bottles are typically packaged in bottles which are made of either high-density polyethylene HDPE or polyethylene terephthalate PET.

The point of danger with these bottles is that, upon exposure to high heats, the plastic may actually melt and seep into the drinking water itself. Consumption of these chemicals is potentially quite dangerous, and can lead to a variety of different health issues depending on the amount consumed. This includes — near windows on hot summer days, in the trunk of your car or anywhere else in your car , etc. But as long as the water is not exposed to extreme heat, and is kept sealed, it should last for a long time.

The second reason that you might not want to drink old bottled water is a bit more straight-forward — taste. Simply put, the taste of water changes over time.

Even sealed bottled water will be exposed to small bits of outside air. As the air mixes with the water in the bottle, it changes its taste, and not in a good way. Think of when you leave a glass of water on the counter overnight, and it has that stale, metallic, oxidized taste to it. A lead contamination crisis gripping the city of Newark, N.

According to state and city officials, yes. But some researchers also say it can be important to store it properly. Researchers have focused in particular on the potential for antimony, a chemical in many plastic bottles, to be released into the water—if the bottle is exposed to high enough temperatures long enough. A silvery metal, antimony is a potential carcinogen that has been tied to lung and heart problems. Most of the studies found that the hotter it gets, the more of a concern this becomes.

And while that may seem like a lot, in the summer and in direct sun, temperatures can easily get higher than that. So water left in the trunk of your car for a week or so could produce dangerous levels. Concerns about the presence of microscopic pieces of plastic leaching from bottles into water has also been a high-profile issue as of late, an issue that could pose health risks. But the association says that happens infrequently and consumers can alleviate any potential issue by storing water in a cool place.

Storing bottled water properly can help prevent bacterial growth and reduce the risk of side effects, such as nausea , stomach pain, vomiting, and diarrhea In particular, warm temperatures can foster bacterial growth and increase the release of harmful plastic chemicals into the water 11 , Keeping bottled water in a cool place out of direct sunlight can help promote proper food safety and reduce your risk of negative health effects.

If you notice that your water has developed an odd taste or odor, you should boil it before drinking or discard it. Bottled water should be stored in a cool place out of direct sunlight and separate from household cleaning supplies and chemicals. Certain chemicals found in plastic can leach into bottled water over time, which could potentially damage your health.

Practicing proper storage techniques can help reduce the risk of side effects and ensure that your drinking water is safe. Being dehydrated can negatively affect your body and brain.
