Senior Airman Jon Turner, 22nd Aerospace Medicine Squadron bioenvironmental engineering technician, tests the pH level of faucet water at the Child Development Center June 15, 2010, McConnell Air Force Base, Kan. Bioenvironmental engineering Airmen do monthly tests on McConnell’s water distribution system at random locations to calculate the amount of pH, chlorine and fluoride in the water. Water samples are given to the state to assure that chlorine levels are at a minimal level of one milligram per liter proper disinfection of drinkable water. The bioenvironmental engineer Airmen use environmental sampling equipment to collect drinking water, wastewater, air, soil and other environmental samples for physical, chemical, radiological and bacteriological analysis.
