This post is going to cover the basics of water purification in a survival situation. I will go over different ways to purify waters and some of the common dangers of non-purified water. We will go over the most common forms of purifying water:

  • Boiling
  • Water Purification Tablets
  • Bleach
  • LifeStraw
Boiling Water

Boiling

The best way to purify water is by boiling it. Everyone has a heard something different about how long to boil water or heat it. A safe suggestion is once the water actually begins to boil wait thirty to sixty seconds and all pathogens in the water will be killed. This is the safest bet for the widest amount of variants, i.e. higher elevation. It is also best to strain the water through a cloth to get particulates out because boiling will not get rid of any of that.

Bleach

Then we come to the next item to help purify potentially contaminated water is a common household chemical, bleach. Be sure to avoid bleach that has perfumes or dyes added it as some of these chemicals may be hazardous to ingest. Also use caution and do not add to much bleach as it may have very harmful effects. The point to this is that the chlorine in the bleach will kill microorganisms. Most household bleach contains anywhere from 5.25%-8.25% chlorine in each bottle. For one quart of water you should put five drops of bleach, a gallon of water will require one fourth of a teaspoon of bleach. From these measurements you should be able to add or subtract to fit your needs. Make sure it mixes well and let it sit for at least one hour before drinking.

LifeStraw

The final water purification protocol I will cover is the relatively new LifeStraw. This is a fantastic product that has revolutionized obtaining water sources when you are out in the wilderness. The base model is made from a BPA plastic and is very light, only two ounces, and does not leave any after taste that can happen from the aforementioned iodine tablets. The LifeStraw can filter up to 264 gallons of water before needing replaced. When used as an emergency tool this translates into a very long life span depending on the situation. It filters 99.9999% of waterborne diseases and 99.9% of water protozoa. As with all these options they kill bacteria and the protozoa and do not filter out any type of chemical contamination. This item is easily the most convenient because you do not need a container if you are around water sources such as lakes, rivers, ponds.

This was an overview of the best and most common ways to purify water in an emergency/survival type situation. Make sure to select water that is not contaminated with chemicals or some type of runoff. Water is the most important compound for all life and unfortunately for us humans without purification almost all the water on this planet is undrinkable. Take these tips seriously because just because you do not think the world will end a bad storm could destroy your normal way of life and water is a top priority.
