In wet area, the problem arises in a more serious way in front of the wastewater rejections in the lakes, case of the lake Mellah in North Algerian. It is from this point of view that this work is registered, bearing on the determination of the capacity of elimination of the micropolluants in the purification plant. Also to evaluate the impact of water of rejection the purification plant on water of the lake Mellah. A prospection of the site from a physicochemical point of view at summer undertaken in order to evaluate the water quality of lake Mellah. The statistical and graphic data processing by the organic pollution index method highlighted a very strong organic contamination at the right of the rejection of the station which tends to be dissipated in the lake. This phenomenon plays a central role in the balance of the biological hydro assessment of the ecosystem.
