ÉTUDE DES POLLUANTS CONTENUS DANS LES LIXIVIATS ISSUS DE LA DÉCHARGE PUBLIQUE DE LA VILLE DE MEKNES (MAROC)

Abstract

The rationale behind this study is to evaluate the impact of leachate resulting from the public landfill of Meknès city (MOROCCO), on the environment and more specifically on the waters of the aquifer. For this, a spatio-temporal monitoring of Nitrites, Nitrates, total germs, Sulfito reducing bacteria, Salmonella was performed at eight stations during the 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 contamins groundwater. However, other different sampling point, are believed to be at the beginning of their infection. As to test this, we analyzed seven samples (water wells and springs) around the landfill by physico-chemical and bacteriological analyzes. We confirm in this study that the marl is a temporary powerful obstacle, in contrast with permanent increasing pollution, generated by the decomposition of waste in landfill of Meknes city.
