Pollution in Tullahan River, Philippines

The Tullahan River (running between the cities of Caloocan and Valenzuela) turns pink as foam from an unknown source covers part of the river. People living in the area say that the formation of effluent in different colors occurs almost everyday. Greenpeace Water Patrol activists don protective suits to highlight this water pollution and unfurl a banner that reads "We Have The Right To Know What's In Our Water!" The Tullahan River is one of the dirtiest rivers in Metro Manila. Several industries, such as paper, pen and dye factories, are located upstream from this site. Greenpeace is campaigning for the government to implement effective policies that will curb and eliminate water pollution, starting with a "right to know" policy which will make it mandatory for factories to report the chemical effluents that they discharge into bodies of water.
