Abstract
The infiltration of percolation of leachate from landfill waste is a source of pollution of groundwater resources. Threats are going to feel on the six components of the environment (air, soil, groundwater, plant, animal and human). This can be compounded at the time of water deficits. The landfill of Ouled Berjal is a standard model of deterioration of water resources. Leachate is contaminated; also water from agricultural practices, the result is the deterioration of groundwater quality. The depth of the water table is low (4 to 15m), so the contamination rate is fast. The analysis carried out on the samples of leachate generated by the landfill show significant average of nitrate concentrations (1518.10 mg / l), ammonium (55.37 mg / l), sodium (3577.60 mg / l), BOD5 (41.36 mg / l) COD (850.11 mg / l), sulfide (1626.71 mg / l) and chloride (7761.74 mg / l).
