In urban areas, population growth generates significant quantities of wastewater that is treated in sewage treatment plants discharged directly or specialize in short uncontrolled water in Bechar Oued. Because of their different origins (domestic waste).Consequently groundwater can be contaminated by chemical and microbiological pollutants. The physicochemical and microbiological characteristics from 18 grandwater samples were measured to evaluate the impact of wadi Bechar wastewater on the Bechar aquifer. The results showed that the majority of samples are contaminated. It revealed alarming levels of chlorides, nitrates, nitrites, sulfates and ammonium. Eighteen groundwater samples are showing signs of recent contamination confirmed by the high rate of tested microorganisms (210 CFU coliform, fecal coliform CFU 91, streptococci D 38 CFU, Clostridium sulfite reducers 4 CFU).
