FIRST INVESTIGATIONS INTO THE POLLUTION LOAD OF LEACHATES FROM THE RABAT LANDFILL, MOROCCO

In Moroccan cities, the problem of solid household waste has arisen with great sharpness in recent two decades. In particular, the management of leachates and the neutralization of their environmental impacts. The need for Morocco to meet the environmental challenge and put itself in a logic of sustainable development has led to an awareness of this issue and the promulgation of the new law 28-00 on waste management and their elimination. The objective of the present study is the characterization of the organic and mineral load of leachate from the Oum Azza landfill and the evaluation of its environmental impacts on the basin of Bouregreg river. For this a campaign of 24 samples was undertaken in 2011 and completed in 2014-2017. The physicochemical characterization of leachates has revealed that these liquid discharges are very high in organic matter very charged in mineral matter expressed in terms of electrical Conductivity. The Rabat landfill represents a real nuisance for health and the environment because of the toxic characteristics of pollutants and bad odors. It is therefore essential to treat these liquid discharges and install a WWTP to mitigate the environmental impact of leachate.
