Like the title indicates I was wondering if bottled water expires? At work I was involved in this stupid holiday weight loss program, and on the last weigh in they gave everyone a bottle of water. Well I was about to drink it when I noticed the date on the bottle was 11/28/03. Thats right, 03 not 04. So I went back and asked the nurse who was in charge of the weight program about the date. Well she was like "Dont worry it wont kill you" and "I have already drank several of them and I am doing ok", so obviously that wasnt convincing enough for me and I gave my bottle to another coworker who was drinking his. That brought me to the question if water expires. I realize pop is carbonated and if its not drank in time it begins to lose carbonation, and juice needs to be drank in time before it goes bad, but what about water?

Aloges, you are correct. The water does not expire, it is the plastic bottle. It begins to release chemicals into the water after the expiry date. You should also never freeze bottled water at any time as the freezing of the plastic bottle has the same affect (whether it is expired or not).
That is also why we should not heat food in plastic containers. The heat also causes the plastic to release chemicals which are bad for you.

There is some debate about heating food in plastic. There are e-mails circulating saying that it's dangerous (my mother, who believes everything she reads, drastically reduced her use of tupperware when she saw this). But from what I understand there is no solid evidence that this is true, no warnings from the FDA or Health Canada or anything like that. Some people think it's a matter of common sense, but I don't know. I believe there have been official warnings about microwaving with plastic WRAPPING on your food, however.
As far as the water expiring, it's not possible for water to go 'bad' in itself. As mentioned above, I think the plastic-y taste is the problem. I seriously doubt that it would be at all dangerous to drink expired water, but the taste might be annoying, hence the expiry date. Most water brands that I have seen set the expiry date at 2 years after production... so it's rarely an issue!

USAFHummer, yes unfortunately, that does include Gladware bowls or any of the other types of the disposable bowls now being sold in stores. Personally, I don't believe everything I read but the quality of the plastic that is being used cannot possibly be of the highest quality seeing they are so cheap.

Indeed... water in plastic bottles is definitely less healthy than decent-quality tap water. Coca Cola have just had to ditch an attempt to introduce their own brand of bottled "table water" in Europe after it became public that not only was their "table water" nothing but tap water (which is generally the case for all brands), but despite all their solemn oaths their version of it actually introduced unhealthy chemicals during their own "purification" process...
As far as I know the most problematic components of plastic containers are the softeners that prevent the plastic from being too brittle. Several of those have been shown to be carcinogenic.
"Carton" containers, by the way, are just plastic containers with an outer carton layer for mechanical stabilization; Inside they´ve got a plastic coating that´s in contact with the content.
The difference is most noticeable with milk; If it "goes bad", it gets a horrible chemical stench and bitter taste in a plastic/carton container; In a glass bottle it simply turns sour.
So apparently the bacteria convert accessible chemicals from the plastic which make the difference to chemically inert glass.

Klaus, whether spoiled milk gets what you call a chemical stench and bitter taste or tourns sour, depends on the temperature and light the milk is exposed to. You can buy all kind of milk products wrapped in plastic.
It is my understanding that water can contain germs and therefore can spoil, 'though it takes quite a while. Even water bottled in glas carries an expiration date.

Water goes stagnant... it flows through the mountain for millions of years. But when it stays in the bottle for say 2 months, it will start to smell and become quite bad for you. not so much the plastic chemicals...

You have made me go to my refrigerator and also take a walk down to the basement.
From the frige.....a .5 liter bottle of Ice Mountain natural spring water. On the side of the bottle is printed....ME 112904 1850 L3 which, I presume, is the date, time and location were this was bottled.....it also says, best by 112906...that bottle never made it till the best by date....I just drank it
From the basement.....a gallon of cheap (79 cents) America's Choice Distilled Water....only thing printed on the side is ..........prod 121404 1328....no best by date printed.
Having a smoking section in a restaurant is like having a peeing section in a swimming pool.....

PET has a very very low surface energy (hence why lables attached to bottles tend to be easy to take off, or have to be significantly glued at all points), and I very much doubt any reaction will take place within a reasonable time. What's more likely to effect taste/safety are the small numerbs of bacteria already in the water/milk/whatever. After enough time, they will release enough metabolic waste to alter the taste.
Check the bottling date and best-before-date on the bottle to determine how fresh the product is. Like many other food products, bottled water normally contains low numbers of harmless bacteria. However, if stored for prolonged periods at room temperatures, these bacteria can multiply rapidly. A 1988 Health Canada study of bottled water kept at room temperature for 30 days showed a substantial increase in the bacterial count
So dates are there because of the reason I said, not because of PET reaction.

I often buy various brands of bottled water as my tap water is rather poor tasting, usually in gallon jugs for $.69. Perhaps the expiration date is because of the sealing of the bottle starts to decline after a time and could lead to contamination, perhaps per recommendation of the liability insurer of the water bottler and to give a date for use by the retailer of the product to properly rotate product. With other beverages, their is definite detariation of the product over time. Usually diet soda and beer has a room tempature shelf life of about 3 months, after which the taste goes bad.

The plastic softeners are phthalates, and they do leach into water over time, and the process is accelerated by heat. They are suspect endocrine disruptors, which means they may interfere with hormonal processes. Truth is, there are thousands of potentially endocrine-disrupting chemicals in the environment at low levels, but these chemicals are so biologically active that even in the nanogram/liter range, they may be exerting toxic effects on living systems. Truth is, genders are becoming more centered, that is, endocrine-disrupting chemicals are making women a bit more like men, and women a bit more like women: androgeny. The long-term effects cannot be well predicted.
As for bottled water, I almost never touch it. I work in the field of drinking water regulation, and trust me, most tap water is better for you than is bottled water. Very few regulations for bottled water, and it's ridiculously expensive.
