    The present survey appears in the context of a multidisciplinary research on the aquatic ecosystems. The aquatic ecosystem of oued Meskiana (wilaya of Oum El Boughi) covers a large area with a permanent flow regime. In order To determine the microbiological and physic-chemical water quality of to the downstream part of oued Meskiana that’s exposed to wastewater discharges from the city of Meskiana, analyses were realized during three different periods at three sampling points. The results showed feacal contamination of this water lotic ecosystem that is represented by the high concentration of faecal coliforms, faecal streptococci and Salmonella. A high Concentration of chemical elements polluting such as phosphates and forms of nitrate were also detected. This pollution affects the environment and constitues a major threat to the health of biological habitats.
