Safe Water

Information about safe water ...

Analysis of the Three Methods of Water Purification Recommended by FEMA and the
Red Cross in the Event of an Emergency.

Method #1:Boiling Water,        #2:Chemical Disinfection,       #3:Steam-Distillation

Kills live micro-organisms? *1
                        YES                                  YES                                     YES

Kills cysts & spores? *2
    WITH PROLONGED BOILING                    MAYBE                                 YES

Removes dead microorganisms? *3
                         NO                                    NO                                     YES

Removes toxins from the water? *4
                         NO                                    NO                                     YES

Removes radiological contaminants? *5
                         NO                                    NO                                     YES

Purifies sea water? *6
                         NO                                    NO                                     YES

Creates high-purity drinking water? *7
                         NO                                    NO                                     YES

Incorporates a phase change? *8
                         NO                                    NO                                     YES

Improved Taste? *9
                         NO                                    NO                                     YES

Does it produce safe drinking water? *10
    PROBABLY SAFE FOR                   PROBABLY SAFE FOR                      VERY SAFE
 SHORT TERM CONSUMPTION       SHORT TERM CONSUMPTION


* Notes:

1. Boiling, chemical disinfection and steam-distillation kills micro-organisms.
2. Chemical disinfection does not necessarily kill spores or cysts. Prolonged boiling and steam-distillation will kill cysts
and spores.
3. Disinfection and boiling don’t remove dead microorganisms or endotoxins created by dead microorganisms. Steamdistillation
does remove these.
4. Disinfection does not remove toxins. Boiling actually concentrates toxins that are present. Steam-distillation is
extremely effective at removing virtually all toxins.
5. Disinfection and boiling does not remove radiological contaminants. Steam-distillation is extremely effective at
removing radioactive contaminants.
6. A properly designed steam-distillation machine can purify highly-concentrated sea water into high-purity drinking water.
7. Steam-distillation produces high-purity drinking water. Boiling and chemical disinfection do not.
8. Steam-distillation changes water from a liquid to a gas and then back to liquid, thus leaving contaminants behind.
9. Chemical disinfection adds chemicals to the already contaminated water. Boiling concentrates the contaminants.
Steam-distillation produces great-tasting water.
10. Disinfection and boiling probably kill the most deadly contaminants, but both processes have major flaws that make
prolonged consumption risky. Steam-distillation produces extremely safe water.
NOTE: No other methods are recommended by FEMA and the Red Cross
