The average person needs 1 gallon (4 liters) of water each day, half for drinking and half for food preparation and hygiene. Increase this number to 1.5 gallons (5.5 L) per person or more for children, nursing mothers, and sick people, and for anyone in a hot or high-altitude climate. Based on these numbers, try to store a 2 week supply for your household. In case of an emergency evacuation, store a 3 day supply in easily transportable containers. For example, 2 healthy adults and 1 child need (1 gallon or 3.8 liters / adult) x (2 adults) + (1.5 gal or 5.7 liters / child) x (1 child) = 3.5 gallons (13.25 liters) per day. A 2 week supply of water for this household is (3.5 gallons or 13.25 liters/ day) x (14 days) = 49 gallons (185.5 liters). A 3 day supply would be (3.5 gallons or 13.25 liters/day) x (3 days) = 10.5 gallons (40 liters). In areas that regulate bottled water, including the U.S. and E.U., sealed bottles of water are already sanitary and will stay good indefinitely. If you go this route, you do not need to worry about selecting appropriate containers or purifying the water. Check the label for certification by the IBWA (International Bottled Water Association), NSF (National Sanitation Foundation), or UL (Underwriters Laboratories). These demonstrate the product has met safety and quality standards. This is more important in countries that do not regulate bottled water. Look for the resin identification code on plastic containers, which typically consists of a number printed next to the recycling symbol. Avoid containers marked “3” (for polyvinyl chloride, or PVC), “6” (for polystyrene, or PS), and “7” (for polycarbonate). These materials can be hazardous to your health. Wash them with soap and hot water, then rinse. If a container previously held food or drink, disinfect it with one of the following methods:  Fill with water and mix in 1 tsp (5 mL) liquid household bleach for every quart (approximately 1 liter) of water. Swish to touch all surfaces, then rinse well.  For stainless steel or...
