Making Water Safe to Drink in an Emergency

In an emergency, your water supply may become contaminated. Use only water that has been properly disinfected for drinking, cooking, or brushing your teeth.

If you don’t have bottled water and cannot boil water, then you can use a chemical treatment to kill most disease-causing organisms. Find out how to disinfect water with chlorine, iodine, or calcium hypochlorite.
