The development of new diesel, gas oil and fuel oil products involves the use of new additives and materials. Fuel handling and distribution is also changing to suit the changing patterns of use. These two factors combine to create environments in which microbes may grow and live inside storage tanks and fuel systems. Contamination resulting in increased costs, lost value, engine and system fouling can occur.

This program shows how such contamination occurs and describes the ways in which installations may be protected from such problems. A series of tests are described which can be carried out on sample drain water or fuel to detect the presence of fungi, yeasts and bacteria. Special emphasis is made in the case of sulphate reducing bacteria, (SRB) as their presence in tanks or fuel systems represents a serious contamination and must be dealt with immediately.

Finally, the program describes the ways in which contamination may be dealt with by the use of biocides.
