__________________________________________
 A. General ú (1) The corrosion caused by the growth of micro-organisms can be a ú serious problem. These micro-organisms, thriving at the interface ú of turbine fuel and any trapped water are fed with the hydrocarbons ú of fuel and mineral salts of water. They produce deposits with ú corrosive action, which have the appearance of slime and vary in ú color from grayish-white, when dry, to muddish-brown or black, when ú wet with water or fuel. ú (2) Fuel/water samples taken from each fuel tank should be tested with a ú microbial contamination kit. Positive results for microbial ú containation require action which can include a biocide treatment or ú physical removal of microbial growth from fuel tanks. ú (3) All instructions supplied with the detection kits should be followed ú closely. Variation in the fuel/water sample and the ability of the ú detection kits to consistently measure the level of microbial growth ú make it important to retest if a detection test shows microbial ú contamination. Do not compare the test results between the ú different types of detection kits. ú B. References ú (1) AMM 12-11-03/301, Fuel Sump Draining
