Water Pollution Facts on Urban Waste and Sewage
The problem of sewage pollution of water bodies is often associated with developing countries where sanitation amenities are inadequate. For example, according to the 2006 report “Caribbean Sea, Venezuela, Central America & Mexico 3bc GIWA (Global International Waters Assessment) Regional Assessment”, about 472,653 m3 of untreated sewage was being discharged on a daily basis into the sea along the coast of the Colombian Caribbean. The eutrophication that took place as a result of sewage pollution had lead to mass fish mortality in areas such as the Cartagena Bay, as well as the destruction of coral reefs in areas like the Islas del Rosario, Colombia.
Nonetheless, it is not only the developing countries that are guilty of polluting the water bodies with untreated sewage. Water pollution facts show that developed countries are also struggling with the same issues. For example, in a 2011 article “Pressure to Improve Water Quality in Chicago River”, the New York Times reported on the pressures that the federal government and environmental groups were placing on Chicago’s waste water treatment firm to stop the discharge of untreated sewage into the Chicago River during storms, and to disinfect treated sewage water before the water was allowed to flow into the river.
In fact, the problem of water pollution by untreated sewage and waste water remains significant today. According to water pollution facts and statistics from the National Resource Defense Council in 2011, as much as 850 billion gallons of sewage that has yet to be treated is being spilt into 770 cities yearly.
