Water Checklist

Store water in plastic containers such as soft drink bottles. Avoid using containers that will decompose or break, such as milk cartons or glass bottles. A normally active person needs to drink at least two quarts of water each day. Hot environments and intense physical activity can double that requirement. Children, nursing mothers, and ill people will need more.
  • Store one gallon of water per person per day (two quarts for drinking, two quarts for food preparation / sanitation)*
  • Keep at least a three-day supply of water for each person in your household

Purifying Water

If you have questions about the quality of the water, purify it before drinking. You can heat water to a rolling boil for one minute or use commercial purification tablets to purify the water. You can also use household liquid chlorine bleach if it is pure, unscented, 5.25% sodium hypochlorite.

To purify water, use the table below as a guide:

After adding bleach, shake or stir the water container and let it stand 30 minutes before drinking.
