Wastewater discharge standards in Latin America
Wastewater discharge standards in Latin America are made to protect water sources and maintain the quality and quantity of them. Mostly in all Latin American countries, there is a general norm that rules both drinkable water supply and wastewater discharges. Also, in most cases is specified other different types of water use, as agricultural, industrial and recreational use. To establish a difference among them, the norm specifies the water quality by controlling the physicochemical and bacteriological parameters. By this way, pollutants as substances of sanitary interest are measured and controlled, encouraging the protection of the water sources, water ecosystems as well as human health. The majority Latinoamerican water laws include tariff regulation and fines, the latter apply if these parameters are not accomplished by users.For the particular case of wastewater regulations, there are different permissible limits that depend on the type of discharge (domestic, industrial), where it is discharge (sewer system, water bodies) and specifying the type of treatment to be use.In general, wastewater content is greatly influenced by industrial discharges, contributing with the majority of the substances of sanitary interest. Therefore, in this paper is presented a summary of the majority of wastewater discharge standards in Latin-America, complemented with a country ranking considering the quantity and severity of their regulations. Also, a comparative analysis of relevant standards is made, and a real case description for each country when the regulation was not accomplished.
