Q. Can Clorox® Regular-Bleach be used to disinfect water?
A. Yes. When boiling of water for 1 minute is not possible in
an emergency situation, you can disinfect your drinking water with Clorox®
Regular-Bleach as follows:
- Remove suspended particles by filtering or letting particles settle to the
bottom.
- Pour off clear water into a clean container.
- Add 8 drops of Clorox® Regular-Bleach (not scented or color-safe) to one
gallon of water (2 drops to 1 quart). For cloudy water, use 16 drops per
gallon of water (4 drops to 1 quart).
- Allow the treated water to stand for 30 minutes. Water should have a
slight bleach odor. If not, repeat and wait another 15 minutes. The treated
water can then be made palatable by pouring it between clean containers
several times.
