    Why does bottled water have a sell by date ?

    Surely water does'nt go "off".

    All companies that produce consumables must, by federal law, have an expiration date on it. Since bottled water is a consumable the company must put a expiration date on it.

    Also some water becomes impure due to plastic melting or substances released into the water by the plastic.
