| Abstract: | Between March 1994 and April 1997, the physical and chemical parameters and chemical composition of the urban solid waste
leachate of the Marbella landfill (southern Spain) were determined. The data obtained show an ammonium and sodium chloride
and bicarbonate type, a pH>7 and high mineralization, effectively described by the following parameters: Na+, K+, NH4
+, Cl– and alkalinity. The chemical composition depends on the rainfall: in dry years, the mineralization and component concentrations
have values as much as double those found in normal rainfall years. After storm events, a major and rapid dilution (within
several hours) is seen in the leachate.
