Microbiological indicators of contamination of the water sources. The growth of the population on a global scale has increased the levels of contamination. This contamination is related to the spilt one of water of waste of domestic and industrial origin to the water bodies. In case of the residues of domestic origin, the load pollutant is represented by high percentages of organic matter and microorganisms of fecal origin. The control of the microbiological quality of the water of consumption and of waste, needs from analysis directed to determining the presence of pathogenic microorganisms, the agents involved in the water transmission are the bacteria, virus and protozoan, they can cause illnesses at different levels of gravity, from a simple gastroenteritis up to fatal cases of diarrhoea, dysentery, hepatitis or fever typhoid. The diagnosis of these microorganisms, it needs specializing laboratories and represents several days of analysis and high costs. As alternative to these disadvantages, the use of microbial indicators has been proposed that could identify by means of the use of simple, rapid and economic methods.

The diagnosis and later recovery of the natural sources of water contaminated, it must do also, bearing in mind the implications that in terms of ecological and sanitary the degradation of the resource represents. In this sense, the perifitic microalga is constituted as good indicators of the state trophic of the ecosystems and answers to the disturbances happened modifying his structure as for composition and plenty refers. This work does a review of the principal bioindicators of contamination and his meaning in the evaluation of the quality of the water.
