Water treatment is any process that improves the quality of water to make it appropriate for a specific end-use. The end use may be drinking, industrial water supply, irrigation, river flow maintenance, water recreation or many other uses, including being safely returned to the environment. Water treatment removes contaminants and undesirable components, or reduces their concentration so that the water becomes fit for its desired end-use. This treatment is crucial to human health and allows humans to benefit from both drinking and irrigation use. Sanitation refers to public health conditions related to clean drinking water and treatment and disposal of human excreta and sewage.

South America is a continent entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a relatively small portion in the Northern Hemisphere. It can also be described as the southern subregion of a single continent called America. South America relies less on the export of both manufactured goods and natural resources than the world average; merchandise exports from the continent were 16% of GDP on an exchange rate basis, compared to 25% for the world as a whole. Brazil (the seventh largest economy in the world and the largest in South America) leads in terms of merchandise exports at $251 billion, followed by Venezuela at $93 billion, Chile at $86 billion, and Argentina at $84 billion. The main agrarian crops are export crops, such as soy and wheat. The production of staple foods such as vegetables, corn or beans is large, but focused on domestic consumption. Livestock raising for meat exports is important in Argentina, Paraguay, Uruguay and Colombia. In tropical regions the most important crops are coffee, cocoa and bananas, mainly in Brazil, Colombia and Ecuador. Traditionally, the countries producing sugar for export are Peru, Guyana and Suriname, and in Brazil, sugar cane is also used to make ethanol. On the coast of Peru, northeast and south of Brazil, cotton is grown. 50. 5% of South America's land surface is covered by forest, but timber industries are small and directed to domestic markets. The main industries are: electronics, textiles, food, automotive, metallurgy, aviation, naval, clothing, beverage, steel, tobacco, timber, chemical, among others. Exports reach almost US$400 billion annually, with Brazil accounting for half of this.
