Water Purification Tablets

When it comes to long term survival there are some rather important things to consider. If you have ever tried Iodine water purification tablets, or if you have never used them before like these Coleman ones, here is something to think about. The yellow bottle which contains the iodine tablets holds only 50 tablets per bottle. And requires 2 tablets for every quart (4 cups, or about 1 liter) which means the max amount of water purification this bottle is capable of treating is 6.25 gallons of water. Now if you sincerely calculate this seeing your average need for water consumption is 1 gallon roughly a day you basically only have about a six day supply if one is purifying filtered clear water. When using these tablets the water has to sit for 30 minutes once the tablets are placed into the water and steer gentile to allow the tablets to dissolve evenly and let sit for 30 minutes. Once 30 minutes has passed the water will then take on the iodine color. Its at this point you can add the PA+PLUS neutralizing tablets, which requires 2 tablets for every quart, and let it sit after steering gentile after applying the tablets for 3 minutes. Then the water will turn back to it clear state and can be consumed. Personally the water taste perfectly fine and there is no iodine taste left remaining in the water. Back in my time in the Marines we did not have this luxury and well drank iodine water to our fill. For those who want to know how to plan for this if you are seeking to have a supply and for an elongation of need. Follow the chart below.

2 Tablets Per 32 oz of water

Product                            Fluid Ounces Cap.              Tablets Required           Total Refill Ability

The Pathfinder Canteen                39 oz                             2 tablets per                        25 Times
Pathfinder Wide Mouth Bottle     32 oz                              2 tablets per                       25 Times
Military Issue Canteen                   32 oz                              2 tablets per                       25 Times

Based on a person who drinks on average 3 full canteens a day which is .75 gallons of water the chart below will indicate how much supply these bottles contain.

The Supply Amount In Days

8 full days and 1 canteen left over supply for one person

If a person where to ration out his water and only drink 64 oz each day the supply would last 12 days with 1 canteen left over supply for one person.

Therefore for a month supply per person who drinks 96 oz per. day would require 4 of these two pack supply to get one person 33 days and 1 canteen bottle supply. While a month supply for a person who drinks 64 oz each per. day would require 3 of these two pack supply to get through 37 days.
