Following a disaster, clean drinking water may not be available. Your regular water source could be cut-off or compromised through contamination. The US Department of Homeland Security and FEMA recommend keeping at least a three-day supply of water on hand, with one gallon of water allocated per person per day. Children, pets, nursing mothers or those requiring medical attention will need additional water. Water needs can also double in hot temperatures. ER Emergency Ration boxed water ensures safe and reliable hydration for all emergencies and locations. Contains 100% purified drinking water that has gone through R/O Aseptic Processing and UHT Pasteurizing. Recyclable, sterilized packaging contains no toxic chemicals, making it a suitable every day alternative to water commercially bottled in plastic than can potentially seep Bisphenol (BPA), nonylphenol, and phthalates. Store extra water in multiple locations for easy access to hydration in an emergency. Guaranteed five year shelf life.
