WASTE DISPOSAL

1. General:
   a. Proper waste disposal is necessary to prevent disease during real world contingencies and training
   exercises. Liquid and solid wastes produced under field conditions can amount to 100 pounds per
   person per day, especially when shower facilities are available. Without proper waste disposal methods
   a camp or bivouac site will soon become an ideal breeding ground for flies, mosquitoes, rats, mice
   and other pests, which can spread diseases such as plague, dysentery, typhoid, dengue fever, and
   other vector-borne diseases.
   b. There are four different types of waste: 1. Human waste; 2. Garbage (Food); 3. Liquid; 4. Rubbish
   (Paper/Plastic/Cans/Glass)
   c. Select disposal methods compatible with location, military situation and regulations.


2. Human Waste Disposal:
   a. Under field conditions, bury human waste when feasible.
   b. Devices most commonly used for various field situations are as follows:
