The instructions below are for treating water of uncertain quality in rare emergency situations in the absence of instructions from local authorities when no other reliable clean water source is available and you have used all of your stored water. Keep in mind that if you store enough water in advance, you will not need to treat water using these or other methods.
1. Method: Boiling
Boiling is the safest method of treating water.
Here are the steps:
2. Method: Chlorination
For both water treatments, boiling and chlorination, water treatment products that contain 5.25 to 6.0 percent sodium hypochlorite are recommended.
Boiling or chlorination will kill most microorganisms but will not, however, remove other contaminants such as heavy metals, salts, and most other chemicals. Before treating your water by boiling it or adding chlorination, let any suspended particles settle to the bottom, or strain them through layers of paper towel, clean cloth, or coffee filter.
In addition to using either water purifiers or water filters on questionable water, you can also treat your water with purification tablets to make it drinkable.
While the two methods described above will kill most microorganisms in water, distillation will remove microorganisms that resist these methods, as well as heavy metals, salts, and most other chemicals.
3. Method: Distillation
Distillation involves boiling water and then collecting the vapor that condenses back to water. The condensed vapor will not include salt or most other impurities.
While the three mention water treatment methods are fairly effective in treating your water to be drinkable in an emergency they are time consuming and require some planning.
Be sure to plan ahead before a disaster strikes, and keep a good supply of drinking water on hand at all times.
