Polluted rivers of Mexico 73%

M. Lopez L. El Mundo de Orizaba, News, 16/12/2012, Mexico.

In Mexico, 73% of the rivers are polluted, the tributaries Veracruz and Coatzacoalcos White top the list, according to the National Water Commission, Conagua. This was revealed in the evaluation of the Fifth National Communication to the convention of the United Nations Framework on Climate Change presented by the Mexican government.


The paper notes that the availability and quality of water determines the productivity of major subsistence activities, but these issues have declined in Mexico, so the sector is one of the most interested in promoting adaptation strategies to climate change.
Water quality is another area that has been difficult to quantify to initiate adaptation actions, it is estimated that 73% of the country’s water bodies are polluted, originated because 80% of discharges from urban centers and 85% of the industrial discharged directly into them.

The use of untreated water for irrigation is a common practice in 180,000 hectares, but the mixture with continuous running water intended for human consumption in the rainy season increases the vulnerability of urban health. At this, the Intermunicipal Council Environmentalists, Cima, said that the actions of the municipalities in the central and Mendoza City, Nogales, Río Blanco and Orizaba, have been minimal to mitigate pollution of the White River.
Illescas Graciano Tellez, president of Cima, said the White River Basin, in addition to suffering from severe pollution along the entire urban area, is accentuated Ixtaczoquitlán area, so it would be interesting to know what have done the mayors in two years managing environmental in the downtown area.

 Availability of water
The 2012 report also notes the average availability in Mexico in 2010 was 4 200 cubic meters per person per year and is estimated to decrease by 2030 and  will be 3 800 m3. The country has an imbalance between availability and demand, as there are basins that uses a low percentage of the total water available, and others using more than 100%. In a couple of decades, 55% of the country will present high levels of requirement.
