An employee of the Camp Liberty Oasis International Waters' water treatment facility uses an air hose to clean debris from a machine at the facility, March 12. The machine uses resin to create the one-liter plastic bottles used to package the water, and regular cleaning of the machine is necessary to prevent melted resin from backing up.
