There is many consequences that comes from the unique setting and contaminations in the Río Tinto, some of them are shortly listen below;

​

• Sediment with contaminations are transported away from the river and are then deposited in Huelva estuary. This leads to pollution in the estuary, that are next to a bigger city. (Nieto et al., 2007)

​

• Due to scarcity of water the need for water reservoirs in the region are high. The contamination, not only in the Río Tinto but also in the Odiel river complicates the development of these reservoirs (Cánovas et al., 2016).

​

• The acidity of the river makes it only possible for certain bacteria to live there. Some of these are; Leptospirillum ferrooxidan, Acidithiobacillus ferrooxidans and Acidithiobacillus thiooxidans (Fernández-Remolar et al., 2005).

​

• The situation of acid rock drainage in Río Tinto are assumed to be what has happened on Mars. Therefore a lot of researches are done there to make it possible to get a greater understanding of the processes on Mars  (Fernández-Remolar et al., 2004).
