Résumé
The Henchir El Yahoudia landfill is one among many uncontrolled dumping sites in Tunisia with no bottom liner. It is located at
the southeastern edge of Sijoumi Sebkha. The site has been exploited since 1963 until 1994. It constitutes a peculiar case because
of its situation, its exploitation mode and the nature of buried wastes. Leachate analysis shows that they are strongly charged
with nitrogen (especially ammoniacal and kadjedahl), organic compounds with a high biodegradability and a charge of metallic
elements exceeding the Tunisian norm NT 106-002. Sediment analyses show that the highest rate of heavy metals and organic
matter coincides with clay-richest layers, characterized by the highest specific-surface values. The percolation of these pollutants
until the groundwater between 0.5 and 5 m has provoked a pollution characterized by high rates of organic matter (BOD, COD and
nitrogen) and heavy metals.
