A mural honoring the Argentine painter Benito Quinquela Martin by artist Alfredo Segatori is reflected in the waters of the Riachuelo river in Barracas neighborhood, in Buenos Aires, Argentina, Tuesday, Dec. 3, 2013. A report by the environmental activist groups Blacksmith Institute and Green Cross of Switzerland ranked the Riachuelo as the eighth most polluted place in the world. The study says makers of chemical products are responsible for more than a third of the river’s contamination, and adds that sample testing indicated 80 percent of water taken from wells near the river is not safe to be consumed.
