Staff Sgt. Anna Hurlbert, 8th Medical Operation Squadron Bioenvironmental Engineer NCO in-charge, holds water reference samples under a black light on Kunsan Air Base, Republic of Korea June 21, 2012. In this example, the bioenvironmental engineer unit is able to determine the presence of different types of bacteria, such as e-coli, by using the black light. Each test and sampling helps ensure Kunsan Airmen and personnel have access to clean and safe water. (U.S. Air Force photo/Senior Airman Jessica Hines)
