Tossing out various links to some of the options everyone has mentioned above;

A deficiency in the Aquatabs is that it's ineffective against Cryptosporidium.

From Aquatabs website at https://www.aquatabs.ca/faq.html. They say it's not common but in a disaster situation I would consider all water sources suspect and assume Crypto is present in the water.

Are Aquatabs water purification tablets effective against the cysts Giardia and Cryptosporidium?
Aquatabs are effective against Giardia when used as directed but have not been proven effective against Cryptosporidium when this cyst is in the oocyst stage of its life cycle. Cryptosporidium is however not considered to be a common cyst. If Cryptosporidium is suspected, boil the water for 1 to 3 minutes depending on elevation or filter to a level of 1 micron absolute and then treat with Aquatabs to inactivate remaining bacteria and viruses that filtration does not generally remove.

I’m putting this in three different sections because it has three different survival functions.



I’ve used this several times to create a chemical fire and it works splendidly.

For my un-treated water I use Calcium Hypochlorite
Since a 1lb bottle treats aprox 10K gallons of water , it goes a long way.

Below good for printing and place in yr book ( you do keep a printed doc book for info don't you just in case? )

I obtained that information a few years ago and reposted it elsewhere. I have a few pounds that cost $7 a pound. Triple wrapped and put in plastic containers as it is hydroscopic. I also put the epa instructions with each package. It might be used if I have to tap my 30 and 50 gallon drums.

If the water were obtained elsewhere, I would set up a number of 2 container solar stills instead. This approach would result in purified water stills without be concerned about salts in pool water and could handle swampy water as well as urine.
