Eielson's waste water treatment plant

EIELSON AIR FORCE BASE, Alaska -- U.S. Air Force Airman 1st Class Jacob Hull, a 354th Civil Engineer Squadron waste water plant operator, pours water into a vial Oct. 19, 2017, at Eielson Air Force Base, Alaska. Waste water can be hazardous to the environment, but once it is processed through the plant it becomes safe to release without the risk of causing harm.
