Just curious how many of you have given thought to the amount of water you can make with just the contents of your PSK...

Personally, I have a vial with 20 iodine tablets and 2 gerber bags. If I fill up the bags to 8 oz (just at the end of the vertical lettering on the right side) and use one of my razor blades to cut the tablet in half then I can get 10 quarts, enough I think for a healthy 5 days.

20 tabs, cut in half = 40 half tabs. 2 tabs treat 32 oz, therefore 1 tab treats 16 oz, furthermore a half tab is good for 8 oz. 40 half tabs at 8 oz apeice gets me 320 oz, or 10 qts.

Any small discrepancy in the halves (i.e. one part being less than exactly half) can be rectified by a longer contact time, hence the two bags - make a bag of water and let it sit for an hour+ while you are drinking from the other.

this doesn't include boiling with 5 sq ft of aluminum foil, my back up which could technically provide unlimited safe water. the tablets are definitely easier though...

From reading the title, I thought this was going to be about the aftermath of a weekend drinking beer <img src="/images/graemlins/ooo.gif" alt="" />

Since my "stuff" is in our vehicle, and there is a PUR water filter right on top of the pile, we can make quite a bit...

Add some plastic bags to you kit and you can make solar still wich will increase your output

"...you can make solar still wich will increase your output..."

Good luck. I played around with solar stills years ago, and was very unimpressed with the puny amount of water produced. Not enough to justify the labor involved as far as I was concerned...

Since I am running around NYC alot, my PSK is geared toward an urban calamity. I carry one bottle (50) iodine tabs, but they are to be used two tabs per litre. I also carry 4-6 plastic bags.

My concern is that if there is a problem in NYC, the contamination is just as likely to be chemical rather than biological. Carrying a Katydyne (sp?) capable of filtering chemicals would make the kit bulky. Still working on that one.

Half a dozen MP1's in my tin. I have always got a waterbottle stashed around me somewhere. That should be enough for 3-5 days. Depending on how warm it is.
I have a nasty feeling that the tin foil is going to go kaput after a couple of days. Which is why I put a kettle/tin cup in my boogie bag.

3 liters... Depending on where you are you might want to seriously think about DXing those Iodine pills for Chlorine Dioxide ones. As Iodine is ineffective against Gairdia.

You can pick up one of these for about $65. It's small and light but takes forever to filter 1lt. of water.

Now, what am I to think about this page from Princeton?

I started out confused and now am MORE confused!
