HOW OFTEN DO I NEED TO RETREAT EMERGENCY WATER IN A CONTAINER TO ALWAYS HAVE IT DRINKABLE?
For containers not exposed to sunlight:
Add tablets every 15 days. If the water is stored in a cool, dark place like a basement, it can remain clean for several weeks. While adding tablets every 2 weeks is recommended for safety, the water may actually stay drinkable for longer periods. If you plan to be away for an extended time, consider doubling the dosage before you leave to ensure the water remains safe.
For containers exposed to sunlight:
Add tablets every 7 days to maintain the water’s quality.
