Heavy metals leached from the waste from the landfill in the city of Meknes,and their impact on groundwater

The aim of this study is to evaluate the impact of leachate emerging from the public landfill in meknès city,on the waters of the aquifer. in order to do this,a spatio-temporal monitoring of physico-chemical parameters (temperature,ph,conductivity,dissolved oxygen,tss,b,cd,cu,fe,hg,ni,pb and zn) was performed at eight sampling points during all four seasons of the year 2013,in order to make a comparison between the pollution load of the leachate and,the possibility that juice discharge contaminates groundwater. physico-chemical analysis showed that the leachate is highly mineralized and less loaded with heavy metals. the results also show that meknes city's landfill is not stable; it has not yet reached its maturation phase. however,other different sampling points are believed to be at the beginning of their infection. in order to test this,we analyzed eight samples (water wells and springs) surrounding the landfill site by using atomic absorption and physico-chemical analysis were performed according to standard protocols afnor [1]. the present study confirms that the marl is a temporary powerful obstacle,in front of permanent increasing pollution,generated by the decomposition of waste in the landfill of meknes city. © 2017,university of mohammed premier oujda morocco.
