Evaluating pollution potential of leachate from landfill site, from the Tangier city and its impact on groundwater (Tangier - Northern Morocco)

摘要

Leachate from municipalities' landfills represents a potential health risk to ecosystems in generally and human populations in particularly. This study which was taken during year from 2010 to 2011was focused to study the physicochemical evaluation of the leachate from the landfill of the Tangier city (north of Morocco). The analyses of the sampled leachate revealed strong content of biodegradable organic matter (BOD =166.78 mg/l, COD=2397.25 mg/l and BOD/COD=0.069) and of SM (SM = 577.97 mg/l). Contents in nitrate (NO3=199.77 mg/l) were also revealed. The discharge of the Tangier city is characterized by an old leachate. The long-term monitoring of the evaluation of physicochemical parameters in polluted leachate, on how environmental conditions change over time, could then lead to models useful in the prediction of natural attenuation in aquifers. Therefore, an adaptable and efficient treatment process must be used to eliminate the wide range of pollutants present in leachate.
