Team effort keeps Balad water supply safe
Staff Sgt. Gary Messer pours bacteria culture food into a sample of water taken from the Air Force Theater Hospital before placing it in an incubator for 24 hours March 13 at Balad Air Base, Iraq. The culture food will drive any bacteria that may be in the water to grow at a rapid rate. This water; however, was free of any bacteria so no reaction or growth occurred. Sergeant Messer, a 332nd Expeditionary Aerospace Medical Squadron bioenvironmental engineer, is deployed from Lackland Air Force Base, Texas. (U.S. Air Force photo/Senior Airman Julianne Showalter)
