Airman 1st Class Ronald Smith, 22nd Operational Medical Readiness Squadron bioenvironmental engineering technician, mixes a vial to test chlorine levels Mar. 3, 2021, at McConnell Air Force Base, Kansas. Facility water chlorine levels are checked by mixing a compound into the water sample. The sample is then placed into a colorimeter that reads the chlorine level and gives the user a number that tells them if it is too high or too low.
