Airman 1st Class Rolando Chavez, 14th Medical Operations Squadron Bioenvironmental Technician, tests the chlorine level of the base’s water supply outside of State Village at Columbus Air Force Base, Mississippi. Too much chlorine can affect the taste of the water and cause drinkers to seek other sources of water, but not enough chlorine will allow bacteria and other microorganisms to survive causing water supplies to carry diseases.
