1 Harbour water pollution study

Generally we observe that the water in the natural environment, in seaport or harbour, present the mineral content of organic matter allowing bacterial proliferation. The presence of mineral ion, nitrogen, phosphorus, sulfur, iron, manganese, calcium in the form of nitrate, phosphates, sulfates brought the necessary element for the growth of those micro-organism analysis. After the interpretation of physical-chemical properties of, water of the harbour, it is sure that this environment favoured necessary conditions for the development of SRB associated to the other micro-organisms like the ferrous bacteria, that accelerated the bacteria corrosion process at the interface water-sediment in the basin. All this data are highlighted by using software which allowed the visualization of these phenomena and to understand their evolution in the long-term. This tool moreover allows the preventive management of environments which are characterized by a large complexity about bacterial and physical-chemical levels
