The Riachuelo is one of the most polluted rivers in a world, ranked 11th by a global study made by the Swiss Red Cross. Around 15.000 industries contaminate the river y chemical manufacturers are responsible for over a third of the pollution in this river. Studies made in 2008 detected nusual high levels of zinc, lead, nickel and copper. 

Over 5 million people live in areas that are affected by the river?s pollution and amongst these, 35% doesn?t have access to clean water. Although since 2008 there have been efforts to decrease, clear results have not yet been seen.

Other rivers in Argentina also suffer from pollution from different sources: agriculture, mining, urban zones and industries. These conflict zones are spread throughout the whole country from the south to the north. 

In the present there aren?t a lot of measures controlling pollution, but changes have been compared if you look at the past. Still a lot of process is yet to be made so that everyone can access clean water.
