John Whitley, director of the U.S. Army Africa Personnel Recovery directorate, displays water purifiers travelers can use when working in isolated areas. The larger device (left) processes several thousand liters of water. The purifier on the right is similar to purifiers that are undergoing testing at U. S. Army Laboratories in Natick, Mass. Individual water purifiers may be added to the Personnel Recovery Directorate’s emergency survival kit once all testing and assessment is completed in the fall.
