The Riachuelo river is not just an eighty kilometer river. It is also a symbol of Buenos Aires. It passes through the city historically as well as geographically. It is core and edge at the same time. All the mythology of our classic urban identity has the Riachuelo as an obligated reference: the mist, the ship that arrived once with loads of immigrants and that is now nibbled by the rust at the bottom of the river. The harbor as a place where y can you start over, a scene to remember the past and to compose some tango pieces. La Boca («The mouth», the neighborhood by the Riachuelo) received this name since it is the mouth of the river, the location through which the river talks. Or spits. Actually, it used to spit: now things pass through the river-bed as if it were a dead man’s throat. The Riachuelo has 0% of oxygen on most part of its course. It has become a «drowned river», mainly due to the over 4100 industries that throw their toxic wastes into it.

Alfredo Clavijo lives on the 11th floor in a flat, overlooking the petrochemical base on the South Dock. From here he can see the industry and suffers from toxic waste that they spew out into the river.
