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
Method #2:
Chemical Disinfection
Method #3:
Steam-Distillation
Kills live micro-organisms? [1]Boiling, chemical disinfection and steam-distillation kills micro-organisms. Yes Yes Yes
Kills cysts & spores? [2]Chemical disinfection does not necessarily kill spores or cysts. Prolonged boiling and steam-distillation will kill cysts and spores. With Prolonged Boiling Maybe Yes
Removes dead microorganisms? [3] Disinfection and boiling don’t remove dead microorganisms or endotoxins created by dead microorganisms. Steam-distillation does remove these. No No Yes
Removes toxins from the water? [4]Disinfection does not remove toxins. Boiling actually concentrates toxins that are present. Steam-distillation is extremely effective at removing virtually all toxins. No No Yes
Removes radiological contaminants? [5]Disinfection and boiling does not remove radiological contaminants. Steam-distillation is extremely effective at removing radioactive contaminants. No No Yes
Purifies sea water? [6]A properly designed steam-distillation machine can purify highly-concentrated sea water into high-purity drinking water. No No Yes
Creates hiqh-purity drinking water? [7]Steam-distillation produces high-purity drinking water. Boiling and chemical disinfection do not. No No Yes
Incorporates a phase change? [8]Steam-distillation changes water from a liquid to a gas and then back to liquid, thus leaving contaminants behind. No No Yes
Improved Taste? [9]Chemical disinfection adds chemicals to the already contaminated water. Boiling concentrates the contaminants. Steam-distillation produces great-tasting water. No No Yes
Does it produce safe drinking water? [10]Disinfection and boiling probably kill the most deadly contaminants, but both processes have major flaws that make prolonged consumption risky. Steam-distillation consistently produces extremely safe … Continue reading No No Very Safe
