Access to drinking water is a human right; and it is one of the basic conditions for good health according to UNICEF / WHO. Polluted water could be the cause of serious illnesses such as dysentery, typhoid fever, type A hepatitis ... etc. The spatio-temporal evolution of the mean densities of the microbiological parameters (CT, CTT, SF) in the waters of the El-Besbes region also showed seasonal variability in the majority of the parameters. This variability was noted in the four different ambient environments: cistern water, tap water, well water, spring water. From a qualitative point of view, the spring waters show compliance with certain microbiological parameters to WHO water standards. On the other hand, for the samples of cistern water, tap water, well water, some greatly exceeded the threshold of the WHO drinking water standard during the two study periods (summer, winter).
