What is the best way to store tap water?
Tap water should be stored in plastic containers, preferably heavy opaque plastic with tight fitting, screw-on caps. Mark the date on the containers when stored and place in a dark location. Use the water within one year and replace. A small amount of household bleach (5.25% sodium hypochlorite), 8 drops per gallon, will prevent bacterial growth. Purchased bottled water can be stored as purchased for several years.
