Sports reviews of Potable Aqua Water Treatment Tablets
Customer Review: Comparing chemical treatment methods
Sport shop rating: 5 Stars
The EPA estimates that 90% of the world's fresh water is contaminated and unsuitable for drinking. The days of kneeling down on a hike and sipping from the stream are long gone. Don't make the mistake of thinking that just because water looks clear or tastes good that it is free of contaminants. That includes frozen water, which can house hepatitis A, Salmonella, and Cryptosporidium for months.
There are many options for purifying the water, but this post will compare commercial products that rely on halogen chemical treatments.
Polar Pure - contains iodine crystals, has an almost indefinite shelf life if kept tightly sealed, and very inexpensive per dose cost, requires measuring the dosage using the cap (which can be imprecise).
Potable Aqua - contains iodine tablets, shelf life of up to four years if properly stored - if they've turned a light green don't use, moderately expensive per dose cost, easy to administer doses (two tablets per quart of water).
Micropur MP1 - contains chlorine dioxide tablets, has a shelf life of at least four years, moderately expensive per dose cost, and comes in easy to administer doses (one tablet per quart of water).
Simple household bleach - 2 drops per quart of water (assuming a a bleach solution of 5-6% hypochlorite), may wish to double the dose for cloudy water, shelf life of bleach is only about 6 months, must use a dropper to administer dose, very inexpensive per dose cost.
Tincture of iodine - 5 drops per quart (assuming a 2% iodine solution), may wish to double the dose for cloudy water, almost indefinite shelf life if properly stored, must use a dropper to administer dose, modest per dose cost.
All of the methods are effective at killing bacteria, somewhat effective against viruses, and of limited value against protozoa cysts. Cryptosporidium in particular is resistant to halogen treatments.
Most treatments only require 30 minutes. However, very cold water (i.e., less than 40 degrees F) should be allowed to sit for 2 or more hours, or be treated with a double dose.
As far as taste, all will introduce some chemical taste into the water. In a very unscientific taste test of chemical treatment methods, my own family concluded that iodine-treated water was by far the worst smelling and tasting, bleach-treated was second, and water treated with Micropur MP1 ready-to-use tablets was the least objectionable.
Finally, you can add Kool-aid to treated water to help the taste. Not only will it help to mask the chemical taste, but the ascorbic acid (vitamin C) converts the chlorine or iodine to tasteless chloride and iodide.

Description of Potable Aqua Water Treatment Tablets
Our Potable Aqua Water Purification Tablets make questionable water bacteriologically suitable to drink. Easy to use-water is ready in 30 minutes. One 50 tablet bottle treats 25 quarts of water. Ideal for hiking, backpacking and travel. Perfect addition to your first aid or travel kit.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.
