Ratio bleach to water for purification?

Answer 1

If you want to sanitize a surface, the bleach solution must be 10:1. 10 parts water to one part bleach. Any higher concentrations may actually decrease the sanitizing effects.

A much safer alternative is simple hydrogen peroxide! "Hydrogen peroxide is the only germicidal agent composed only of water and oxygen. Like ozone, it kills disease organisms by oxidation! Hydrogen peroxide is considered the world's safest all natural effective surface sanitizer. It kills microorganisms by oxidizing them, which can be best described as a controlled burning process. When hydrogen peroxide reacts with organic material it breaks down into oxygen and water."

Answer 2

The recommended ratio for purifying water with bleach is 8 drops of bleach per gallon of water. This can effectively kill harmful bacteria and viruses to make the water safe for consumption. Mix the bleach thoroughly into the water and let it sit for at least 30 minutes before drinking. Always use unscented bleach that contains 5-6% sodium hypochlorite.
