There are no doubt concentrations beyond which some sort of health issues manifest themselves, but apparently not till you reach far higher concentrations than we are talking about here according to those with which I have consulted. You can die from too much pure water as well. <img src="images/graemlins/grin.gif" alt="" /> This is simply what I have discovered in my research on this subject over the years and the answers I received I find satisfactory for my purposes WRT survival use. I have used many of these products in such manner without adverse effect. YMMV and far be it from me to try and convince you otherwise. You can always use alternate methods, larger containers or cut the tablets or amounts to maintain the original ratios, or die of dehydration if you so choose. <img src="images/graemlins/crazy.gif" alt="" />

This where that condom comes into its own. It might not be as resiliant as some plastic bags, but it will hold the amount of water!

Well, this discussion has answered some of my concerns, which is why I asked the question in the first place. Again, this is one of the major highlights of the Survival Forum, this exchange of information, opinions, etc.

Maggot and Tackdriver303,

The concerns you both have about Potable Aqua iodine tablets are not an issue for me or any other experienced climber or hiker, even if you ingest 2 or 3 ounces of pure iodine crystals the most that could happen to you is that you could possible get sick and possible die.

But if you but if you eat something afterwards you might not,
but if you are allergic to iodine you probably will.

Discuss it with your Doctor if you doubt the validity of the information.

The Potable Aqua iodine tablets are save even in the amounts you outlined.

What Doug is telling you is the best information available on the subject!!!!!!! I have been hiking and climbing for 20 years, this site has first class information.

Hi Maggot,
Interesting discussion. Thanks for bringing it up.
For those who still may have reservations regarding this matter...
My first thought is to have three breast milk bags. Dissolve one Potable Aqua tablet in one, then divide the contents evenly into the three and fill them all. This approximates the correct dilution. If you don't have three breast milk bags, dissolve one tablet into one bag, pour two-thirds of it out and fill it full again. It's wasteful, but better if you (or someone else) was really concerned about concentration.
My second thought is that I really need to go try to split a Potable Aqua tablet into parts with my Micra to see how hard it really is.
My third thought is that David's fish bags (or oven bags) might be the better solution for kits that have room for them.
Stay safe,
J.T.

Let me throw in my 2 cents for what it is worth. Our lab is responsible for monitoring the health status of research animals. One common practice is to treat water with either chorine or acid to reduce microbiological contamination. Water is treated with chlorine to achieve 8-12 ppm of available chorine. At these levels the water does have bacterial static effects on intestinal organisms. Pseudomonas aruginosa is one indicator organism for which we monitor, being both an opportunistic pathogen as well a common fecal contaminate. Chorine levels are affected by light, organic materials (bedding, feces, etc.) and dissipation. Generally within 24 hrs, original chlorine levels of 8-12ppm are below 0.5ppm. When monitoring for Pseudomonas aruginosa levels (from feces), during the first 24 hrs, levels of the organism are below detectable levels, as the available chlorine levels are decreased (24hrs+), there is a rise in the detectable levels in Pseudomonas aeruginosa isolated from feces. It is general practice to change chlorinated water bottles every 2-3 days. Acidified water, reduced to a pH of around 3.0-4.0 is stable from both a chemical and bacterial static point of view for 5-7 days. The water for both mythologies is generally not palatable to humans.
