AB The Iberian Pyrite Belt (IPB) is rich in sulfide deposits which have been intensively exploited, generating a huge problem ofcontamination of the Odiel River by acid mine drainage (AMD). At its source is a clean river, but along a 7 km-long reachreceives five discharges of acid mine waters: Concepción, San Platón, Esperanza, Poderosa and the Agrio River, which drains theAMD contaminated water from the Río Tinto mines. The flows and hydrogeochemical characteristics of these AMD sourceshave been studied. The Agrio River is the main contributor of acidity, sulfate and metals to the Odiel River due to its high flowsand pollutant concentrations. San Platón and Poderosa mines have high sulfate and metal concentrations although both sourcesare characterized by low or moderate flows while Concepción has the lowest concentrations but higher flows. The composition ofAMD sources seem to be controlled by the mineralogy of the deposits and by geochemical processes. Strong seasonal variationsare observed for some AMD sources while others are more constant throughout the year.
