You're right, pure spring water doesn't need a sell by date. It won't go off.
It's pure water. As such there are no nutrients in it. Therefore, if there were any bacteria in it they would all die. You can see this in pure water springs. Immediately around where the spring emerges from the rock into a pool or lake, there is no life whatsoever; not bacteria, not algae, not nothing. The water is *so* pure, nothing can live in it.
So, why does bottled spring water have a date then? Because it's a consumable and, by law in this country, all consumables must have a sell by date.
Daft, but there it is!

Give up. Just boil tap water and bottle it yourself. The taste of some bottled water is horrible. Just another way for companies to make money from consumers. As are the made up words like perfidious degestium from yogurt company's. If you eat healthy and drink plenty of water you wont need the man made anti toxins.

Bacteria has been introduced during the pumping, processing and packaging steps. It multiplies over time to an unhealthy level. The bottlers do not want to be held accountable for any possible contamination after a certain bottling date, whether or not they introduced it.

Rubbish! It is all rubbish what did they said. Water only has validity period because of gas in it. Plastic bottles are not toxic! I'm a chemist and plastics engineer. I know about what I'm speaking. Diffusion of the gas, that's the answer to your question! Gas from water bottles escape, and water become unsalable.

Water needs conservatives to stay fresh, in their natural body it does not, because together with the bacterias and bad bugs there are good bugs that keep water clean, in the bottle or in a wood barrel like in the old days in ships the water goes bad, becouse of the bacteria it has. rremember mineral water isn't boiled and bottled.

For the same reason the FAA requires placards in certain models of Beechcraft airplanes that reads, "When the fuel gauges register empty there is no more useable fuel in the tanks." Uh...yeahhhh!

Stephen C just spouts the mantra, plastic is safe. How does he KNOW. I can remember when lead was safe asbestos was safe PCFs were safe aluminium was safe dioxins were safe mercury was safe. Even Madame Curie knew that radium was safe.
Sorry Steve just can't believe you.

DUH.........Volcanic rock vs. Polyethelyne bottle. micro organism ought to start to strengthen i the bottles with publicity to gentle. Chlorine oxidizes with publicity to gentle hence if uncovered for tremendous sessions of time it ought to deplete the residual chlorine. additionally if left for long sufficient the plastic style of the bottles might permeate the style of the water.

......once water remains stagnant it will have a sell by date. When it is flowing through rocks and has air oxygenating it it won't go off.

as water flows it maintains it's clean taste,once it is bottled,and often the containers are plastic,they sit on selves and or in boxes.Plastic is a porous material and can be breached.
