I recently inherited a bunch of stuff among which was a case of "Mainstay Emergency Drinking Water" packed in individual 4oz foil packets.
My question is, It's dated 1998 - Any idea on what kind of Shelf life this stuff has, or should I just use it as targets? I suppose I could always try one, But I'm wondering since it's 12 years old already, If it has run it course or if I can keep it around for a few more years.
The shelf life would depend on what the ingredients are, I believe. I don't think I'd trust it since it is 12 years old and obviously has no expiration date on it. If you are looking to have some water purification supplies, I'd start with something new, in it's original package with directions for use and an expiration date. I sure wouldn't want to scoop out some river water and give this item a try only to discover it's too old and doesn't work.

I believe it's just water sealed in 4 oz Foil Packets. I'll probably use it as Targets, I have tons of Survival supplies including a few water purifiers, But I thought if it was a chance it'd still be Good..Well, Why not keep it.
I just did a search and the water retorts I found had a five year shelf life. Personally, I'd try a few and check the quality. Canned goods last a whole lot longer than the Best Used By date, water may be the same.
Canned goods nutrients and texture can be lost over time, but unless they've been exposed to air, they're edible and will keep you going. I wonder if it's the same for water. Obviously not texture, but the growth of algae or whatever. As far as I know, retort water is produced through some type of distillation process.

Water is extremely stable. If it was stored properly with no contaminants, it should be fine indefinitely. Keep those emergency packets as they are. If you're concerned, pour them through a filter before drinking.
What you both say makes sense, these came from a buddy of mine who passed away, He was prepared to survive WW3 - I know he was big on rotating his stuff around, But He had been sick for awhile, So I guess these didn't see the light of day. He did store everything under optimal conditions though, So maybe I'll break open a few and try them out.
