Water Purification Hints
There are some things you really need to know if you are ever in a situation where you are performing emergency water purification. One thing to remember is that you should filter the water first through multiple layers of cloth, paper coffee filters, etc. Another thing you should really keep in mind is that if you are using bleach to cleanse the water, that bleach has a shelf life. You will need to use twice the amount of bleach if it is a year old, and two-year old bleach is pretty much useless. Finally, one thing that is very important is that you should only purify about two days worth of water at a time because after two days it could become contaminated again.
