Recent unconfirmed reports of problems in refueling systems induced by microbial activity prompted an investigation of refueling facilities at four Air Force bases. The distribution and servicing systems and aircraft surveyed were remarkably free of water, only 26 of 66 attempts to obtain water being successful. Those samples in which water was found contained considerably less than observed in previous field investigations. Fuel System Icing Inhibitor, known to exert an inhibitory effect on microorganisms, was present in the water bottom samples in concentrations ranging from 7 to 25 by volume. Microbial levels, both fungal and bacterial were inconsequential. This survey has shown the facilities evaluated to be free of significant microbial contamination, attesting to the beneficial results of excellent housekeeping procedures.
