If water supply becomes contaminated, you can either boil water for one minute or make water safe with bleach.

Here is how:

If tap water is clear:

1. Add eight drops of household unscented liquid bleach to one gallon of water.

2. Mix well and wait 30 minutes or more before drinking.

If tap water is cloudy:

1. Add 16 drops of unscented household liquid bleach to one gallon of water.

2. Mix well and wait 30 minutes or more before drinking.

In addition:

• Never mix bleach with ammonia or other cleaners.
• Open windows and doors to get fresh air when you use bleach.
