· The waters of the Rio Tinto flow red due to a high concentration of ferric iron. The river is known as an extreme environment due to its low pH and high concentrations of heavy metals. The region has been an important copper mining area for the last 5000 years.
Acid mine waters contain high concentrations of dissolved heavy metals and sulphate, and can have pH values as low as 2.5. Unless treated, such waters may not be discharged into public streams. The acid water is formed as a result of bacterial oxidation when pyrites are exposed to oxygen and water after or during the mining process.
Toxic elements, such as copper, Mining accidents with this type of mine have occurred very acidic waters (pH < 3),
