Step 1: Clarify
Cloudy or dirty water must first be made clear. It may be passed through filter paper, fine cloth, or other filter. It may be allowed to settle and the clear water on top carefully drawn. Filtered or clear settled water should always be disinfected before use.
Step 2: Disinfect
Boiling Method
Bringing water to a rolling boil for 3 to 5 minutes will kill most water-borne microorganisms. However, prolonged boiling of small quantities of water may concentrate toxic contaminants if present.
Bleach Method
Adding 1/8 of a teaspoon (8 drops) of fresh liquid household chlorine bleach (5 to 6% sodium hypochlorite) to every gallon (4 liters) of water will kill most microorganisms. Only household bleach without thickeners, scents, or additives should be used. The use of bleach does not address toxic contamination.
Commercial Water Filters
Commercial water filters can effectively filter and purify water contaminated with microorganisms, toxic chemicals, and heavy metals. Their effectiveness depends on design, condition, and proper use. Water filters produced by Seychelle have been used successfully by Church missionaries for many years.
