# Storing Water

Store at least **one gallon per person per day**, with a two-week supply as a
practical target for a fixed location.

## Containers

Use food-grade containers marked with recycling code 2 (HDPE). Never reuse
containers that held milk or fruit juice — residual sugars and proteins support
bacterial growth no matter how well you rinse.

Keep containers off bare concrete. Plasticizers migrate and the floor stays cold
enough to cause condensation cycles.

## Rotation

Commercially bottled water carries a manufacturer date; rotate it every two
years. Water you bottled yourself from a treated municipal supply should be
rotated every **six months**.

Store away from sunlight and away from gasoline, pesticides, or solvents —
vapors permeate plastic over time.
