Water Treatment in the Field: CSTX 91-22-01
Army Reserve Cpl. Brandon Vickers, a water treatment specialist assigned to the 651st Quartermaster Company based in Casper, Wyoming, tests newly purified water with a chlorine test strip during Combat Support Training Exercise 91-22-01 at Fort Hunter Liggett, California, June 15. The test strip Vickers is holding shows that the chlorine level of the water is 2.0 parts per million by matching the color on the strip to the bottle's key. (U.S. Army Reserve photo by Spc.
