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 mgL Co 0.92 mgL Hg 0.009 mgL Cr 5.14 mgL As 1.95 mgL Cd 0.41mgL and Mn 61.52 mgL 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.
