BURN PITS (TRASH AND HUMAN EXPOSURES) A RESOURCE FOR VETERANS, SERVICE MEMBERS, AND THEIR FAMILIES Exposure to burning trash and human waste, including feces, is a concern for those who have served overseas in countries like and .

Proper disposal of waste during deployment is essential to prevent health problems and protect service members. In certain situations, when sanitary and facilities are unavailable, this waste may be burned in an open pit. Pits used for this purpose are referred to as “burn pits.” Since any particular trash burn is made up of several materials, it can result in different mixtures of chemicals released in the smoke. Because of this, it is difficult to quantify the levels of exposure to harmful chemicals that an individual service member may have had. A person’s exposure is also dependent on how close an individual was to the burn pit, in which direction the smoke was blowing, and the length and frequency of their exposure. There is little actual testing data that has measured levels of possible in individual service member’s breathing environment(s) when burn pits were in use.
