There are a number of motives for an expiration date on a bottle of eating water. some states require that each nutrients merchandise has an expiration date, so even candy or nuts and different perishables could have them. the different reason is the flavor. as long as a bottle of water keeps to be unopened, that's risk-free to drink.

The plastic of the container could make the flavor pass undesirable while this is not saved appropriate. additionally, solar can visit pot the plastic and upload to the undesirable style.

Water, like any other product, can go bad. If it sits too long it will get moldy and bacteria will grow. Just think about a swamp, if the water is still for a while, algae and other gross stuff coats the top of the water. Also, after a while, the plastic in the bottle will start breaking down. Toxins in the plastic can enter the water, and drinking the water could make you sick.

Answer 4

I have been in food/water quality assurance for years. The date has several reasons. First it allows the manufacturer to trace the water back to a specific production run in case of complaint. Next, it makes it easy to rotate stock in warehouses and stores so the product stays fresh. As the water ages in the plastic bottle, it can pick up plastic notes in the flavor which some people don't like. The gases dissolved in the water also come out of solution leaving the water tasting flat or bland. While the water would not become unsafe to drink, it doesn't taste as good as the manufacturer would like... none of us wants to disappoint a consumer!

Answer 5

This is a common practice in the US.

In the United States bottled water's shelf life is date stamped for two years.

Properly stored bottled water has indefinitely shelf live. However, long-term storage of bottled water may result in aesthetic defects, such as off-odor and taste.

IBWA advises consumers to store bottled water in an unopened container at room temperature (or cooler), out of direct sunlight and away from solvents and chemicals such as gasoline, paint thinners and dry cleaning chemicals.

Answer 6

Water reacts with the plastic container and gets contaminated. Hence use before the expiration date.
Educated by my local recycler about plastics. Local tap water now has to deal with filtering 'perchlorates" a component of rocket fuel. Used to be buried underground in the 50's and 60's. Not allowed anymore since groundwaters are being affected. Check Glendale, Los Angeles recently.
