Product Description

Amazon.com

Used worldwide by campers, hikers, militaries, emergency organizations, and anyone else who needs to drink water of questionable quality, these Portable Aqua iodine tablets will disinfect contaminated drinking water in a pinch. The tablets--which are intended for short-term or limited emergency use only--make most water bacteriologically suitable for drinking, proving effective against Giardia lamblia when used as directed. Each Potable Aqua tablet contains 20 mg of Tetraglycine Hydroperiodide (TGHP), which liberates 8 mg of titratable iodine when released into water. Within 30 minutes, the iodine will have penetrated the cell walls of the microorganisms, rendering them inactive and making the water safe to drink. Potable Aqua tablets also neutralize the iodine aftertaste and color, helping your drinking water taste better.

About Potable Aqua

Pharmacal currently supplies the U.S. Military with Potable Aqua for its emergency drinking water needs. Potable Aqua is also widely used by campers, backpackers, and various other militaries around the world. With the addition of the Potable Aqua Traveler and Chlorine Dioxide Water Purification Tablets, Potable Aqua continues to meet the ever-changing needs of today's outdoor enthusiast.

The treatment tablet let a bitter after taste in the water, but it did the job.

Although we haven't used them yet, they were bought as a great addition to our emergency kits in case we need them.

That's a pretty good shelf-life for something that can save your life in a pinch.

These do what they're supposed to do. Before I give a review, I'll quote the box on a few points.
1. For use only when drinking water is suspected or known to be bacteriologically substandard. Not to be used on a continuous basis. (Their website suggests a six-week limit.)
2. Unopened bottles should remain effective for four years. (Look at the bottom of this review for how to date your tablets.)
3. We recommend that you do not keep an opened bottle for more than one year.
4. 2 tablets make one quart of bacteriologically water suitable to drink.
5. Proven effective against Giarda Lamblia when used as directed.
6. Has not been shown to inactivate Cryptosporidium cysts.

In a nutshell, use according to the directions and you'll be just fine. The bottle contains 50 tablets; you use two per quart of water. In really murky water, I use three. The active ingredient is Tetraglycine Hydroperiodide 16.7% and each tablet contains 6.68% of Titratable Iodine. This is the same stuff that I used in the military, but just to be sure, I opened a bottle and got three quarts of water from the Ohio River. Murky stuff. The first quart was treated with just the Potable Aqua (2-1/2 tablets). The second quart was boiled for ten minutes. The third quart was boiled for ten minutes, then given two tablets of Potable Aqua. All water was filtered through an untreated handkerchief first to remove debris and sediment. I'll note that my measurements were three quarts before boiling, so I'm sure some of the water was lost in the last two quarts due to the boiling process. The results?

While none of the water was as good as tap water, I'm still alive. The first batch (just Potable Aqua) was okay.

The 5 most common ways backpackers/campers purify water are
1. Boil it. Obviously slow and cumbersome. If doing strenuous backpacking/canoeing each person will need to boil a big pot of water every night.
2. Natural sunlight - letting water sit in the sun for 6 hours works (need cloudless day, correct kind of clear plastic container). The World Health Organization published a study on this, but Amazon won't let me link to it.
3. Water pump - I have used MSR HyperFlow Microfilter, though there are cheaper options if you can accept it being slightly larger. In my opinion this is the best method.
4. Household chlorine bleach - the EPA and WHO give instructions on doing this. The EPA says this may not kill Cryptosporidium. I've never tried.
5. Iodine tablets (or other chemical treatments)-

Positives:
-Tablets are small/light for backpackers
-Only takes 30 minutes to have water ready
-No work required

Negatives:
-EPA says it is not 100% affective against Giardia and Cryptosporidium, especially if the water is cold while being treated.
-The taste is slightly bad ('metallic' is my best description).

I think a good attitude towards these tablets is "emergency use" (which is labeled on the side of the bottle, not visible in the Amazon image). No good backpacker doesn't have these, but I suggest a water pump as the planned primary method. Note: there are also iodine "neutralizer" tablets that are supposed to remove the bad taste (you drop them in after the 30 minutes is up and wait another 30 minutes). In my opinion they barely change the taste and are not worth it.

I'm only giving 4 stars since the EPA says it is not 100% effective against Giardia and Cryptosporidium. I'd give 5 stars if the product was named something like "EMERGENCY AQUA" instead of "POTABLE AQUA".

These are great to have when camping and traveling, but it's important to have a basic plan for water beyond the iodine tablets. You're really only supposed to use them in emergencies. If you're backpacking and need to drink the local water, you should take a filtration system with you or boil the water. This is a good backup to boiling and filtration if you're short on time, or you have equipment problems. Drinking water purified with iodine also tastes foul which is a big issue in rehydrating foods.

Also note that once opened, the Portable Aqua has a limited shelf life.

Save your money. You can find these exact tablets in Wal-Mart cheaper and there's no shipping. Amazon should figure a way to combine shipping costs better to sell the small things like this. Unless you live a hundred miles off the beaten path, go to a major retailer and get these. On the plus side, these are excellent in an emergency kit as anticeptic for cuts. Just take a couple of tablets and dilute them in a little water and you can sterilize minor wounds.

When I hike in the wilderness I always carry an aluminium canteen & mug because then I can scoop up water and boil it to kill any micro-organisms that otherwise would create a party in my intestines. But when you're on the move you don't always have time to make a fire and boil water for 10 minutes, then wait for it to cool before drinking. These tablets can be dropped into any water container and voila, ten minutes later you have cool safe water to drink. A must-have anywhere in North America and they weigh practically nothing.
