The drainage network of the Odiel River is deeply affected by acid mine drainage (AMD) due to intense sulfide mining, especially during the second half of the nineteenth century and the twentieth century, which has left huge amounts of wastes throughout the entire basin and created a serious environmental problem. The acidic waters generated have very high concentrations of metals, which make unviable the passive treatment systems developed in other mining regions.DAS (Dispersed Alkaline Substrate) technology, developed especially for highly pollutant leachates, is a treatment option that has already been implemented in the Odiel basin. In thi s work the results of monitoring of 9 AMD sources (La Lapilla and La Sabina in Tharsis and Poderosa, San Platón, Tinto Santa Rosa, San Telmo, Almagrera, El Carpio and Lomero Poyatos) are presented with the aim of their possible treatment with DAS. The average flow rates varied between 1.4 and 102 m3/h and were recorded concentrations up to 2155 mg/L of Fe, 1796 mg/L of Zn, 772 mg/L of Mn, 489 mg/L of Al, etc.With the exception of one of the controlled points (San Telmo), in the rest it is possible the construction of DAS-plants, although the cost will depend on the pollution load of each point .
