Airman 1st Class Joseph Weidman, 3rd Civil Engineer Squadron Water and Fuel System Maintenance, releases water from one of Elmendorf’s fire hydrants April 29, 2010, at Elmendorf Air Force Base, Alaska. The fluoride levels in the water have been elevated at Elmendorf and Fort Richardson. By releasing some of the water on Elmendorf at various hydrants it decreases the fluoride level.
