The link takes you to a downloadable publication: Food and Water in an Emergency - FEMA. It is on the Red Cross.org website. Pretty standard overview of food and water prep for an emergency. What I found interesting was the homemade/improvised water distiller. Very simple build:metal stock pot with a few inches of water, with lid with handle in center of pot lid. tie cup to pot lid so that when pot lid is inverted and put on the pot, condensation will fall in to the cup from the lid.
