The presence of heavy metals in landfill leachates poses a risk to the environment, especially in the unpaved dumps where their dissipation in groundwater might occur. This study is focused on the assessment of heavy metal load in landfill leachate of El Hajeb (Morocco) and their effects on the environment in general. To do this, raw leachate samples were collected monthly from basins available at the heart of the landfill and analyzed using the atomic absorption spectrophotometer (AAS) to quantify the heavy metals during the period which extends of May, 2015 to February, 2017. The results showed the presence of Pb (2.68 mg/L), Co (0.92 mg/L), Hg (0.009 mg/L), Cr (5.14 mg/L), As (1.95 mg/L), Cd (0.41mg/L) and Mn (61.52 mg/L) in significant amounts. What makes these extremely toxic effluents and thus presented a potential danger for the health of the riparian population and the adjacent groundwater. The determination of heavy metals content will thus make it possible to orient the choice of the leachate treatment process to answer the strictest standards of rejection.
