Foods - Water - Minimal Filtration and Disinfection

Regardless of the source of your water, it should be filtered at some level to minimally remove solids and biological contaminants. If you do not have safe water available, grapefruit seed extract and food grade 35% hydrogen peroxide are safe and ideal methods of disinfecting potential drinking water.

If using grapefruit seed extract, add 10 drops to 3.785 litres/1 gallon of water. Shake or stir vigorously and let stand for several minutes. The slightly bitter taste, if any, is inherent to the extract.

Food grade hydrogen peroxide should be purchased from a health food store. Hydrogen peroxide from drugstores should not be consumed as it contains harmful chemical additives. If using food grade 35% hydrogen peroxide, add 15 to 30 drops 35% hydrogen peroxide to 3.785 litres/1 gallon of water. If the water tastes like bleach, let stand in an open container for several hours. For long-term water storage (more than two months) add 30 to 50 drops 35% hydrogen peroxide to 3.785 litres/1 gallon of water. For more information, see the dedicated section on Hydrogen Peroxide (Food Grade - 35%).
