Brazil's Water Warriors: Strategies To Combat Pollution

Water pollution in Brazil is caused by leaking landfills, industrial waste, and sewage. Solutions to this problem are being sought, but low-cost solutions are limited and incinerators are expensive to buy and maintain. Water pollution is also caused by the chemicals used in the production of crops, which leads to water contamination.

Leaking landfills, industrial waste and sewage

Water pollution in Brazil is caused by leaking landfills, industrial waste and sewage. The three main causes of water pollution in Brazil are the leaking landfills, industrial waste and sewage. Landfills cannot last forever and they eventually fail and leak into the ground and surface water, ultimately polluting it. Water pollution is also derived from ethanol production. Due to the size of the industry, its agroindustrial activity in growing, harvesting, and processing sugarcane generates water pollution from the application of fertilizers and agrochemicals, soil erosion, cane washing, fermentation, distillation, the energy producing units installed in mills and by other minor sources of waste water.

The state water company Sabesp projects that a minimum of R$3 billion (US$1.7bn) would be necessary to clean up the river. The South and Southeast regions of Brazil experience water scarcity due to overexploitation and misuse of surface water resources, mostly attributable to heavy pollution from sewage, leaking landfills, and industrial waste. Water pollution is also derived from ethanol production. Due to the size of the industry, its agroindustrial activity in growing, harvesting, and processing sugarcane generates water pollution from the application of fertilizers and agrochemicals, soil erosion, cane washing, fermentation, distillation, the energy producing units installed in mills and by other minor sources of waste water.

The disposal of waste takes place in inappropriate landfills. As of 2007, the state water company Sabesp projects that a minimum of R$3 billion (US$1.7bn) would be necessary to clean up the river.

The new solutions have not yet been adopted in Brazil as an incinerator for example is expensive not only to buy but also to operate and maintain in a good condition. Change can only happen with the appropriate financing of the project. Landfills cannot last forever and they eventually fail. They leak into the ground and surface water, ultimately polluting it. With the Soccer World Cup and the Olympics coming up, cleaning the waters has been become much more of a priority than it already has. However the progress is very slow as low-budget solutions are limited. The government is doing all they can to clean up these waters for tourist and health reasons.

High levels of pollution in export-related industries

Brazil has a high concentration of pollution-intensive export industries due to trade liberalization. The highest levels of pollution intensity are found in export-related industries such as metallurgy, paper and cellulose, and footwear. Brazil's major and medium-sized metropolitan areas face increasing problems of water pollution. Coastal cities such as Rio de Janeiro and Recife suffer from the effects of upstream residential and industrial sewage contaminating feeder rivers, lakes, and the ocean.

The three main causes of water pollution in Brazil are leaking landfills, industrial waste, and sewage. At the beginning of the 20th century, Brazilian cities had adopted a separate system for the sanitary sewers and the storm water runoff. These two systems were gradually interconnected, and today low-cost solutions are being sought to fix this mix-up. This is a major threat to water quality as the water now collects what is coming from the sewage and is brought into the water, polluting the water and making it undrinkable and endangering wildlife.

Ethanol production and agroindustrial activity

The South and Southeast regions of Brazil experience water scarcity due to overexploitation and misuse of surface water resources, mostly attributable to heavy pollution from sewage, leaking landfills, and industrial waste. According to an investigation by Unearthed, more than 1,200 pesticides and weedkillers, including 193 containing chemicals banned in the EU, have been registered in Brazil between 2016 and 2019. Water pollution is also derived from ethanol production. Due to the size of the industry, its agroindustrial activity in growing, harvesting, and processing sugarcane generates water pollution from the application of fertilizers and agrochemicals, soil erosion, cane washing, fermentation, distillation, the energy producing units installed in mills and by other minor sources of waste water.

It was said that thirty years ago, wildlife was blossoming in Rio but today no fish can be found and there is more chance finding a corpse in a river than a living creature.

Brazil has a high concentration of pollution-intensive export industries. Studies point to this as evidence of Brazil being a pollution haven. The highest levels of pollution intensity are found in export-related industries such as metallurgy, paper and cellulose, and footwear. Brazil’s major and medium size metropolitan areas face increasing problems of water pollution. Coastal cities such as Rio de Janeiro and Recife suffer effects of upstream residential and industrial sewage contaminating feeder rivers, lakes, and the ocean. In 2000, only 35% of collected wastewater received any treatment. For example, the Tietê River, which runs through the São Paulo metropolitan area (17 million inhabitants), has returned to its 1990 pollution levels.

Natural irrigation and artificial water spray

Water pollution in Brazil is caused by leaking landfills, industrial waste, and sewage. Natural irrigation is used to produce crops, but water availability is not a problem in Brazil. The high demand in the production of sugar made the plantation expand in regions where natural irrigation is simply not enough and must be complemented by artificial water spray. The disposal of waste takes place in inappropriate landfills. The state water company Sabesp projects that a minimum of R$3 billion (US$1.7bn) would be necessary to clean up the river. The South and Southeast regions of Brazil experience water scarcity due to overexploitation and misuse of surface water resources, mostly attributable to heavy pollution from sewage, leaking landfills, and industrial waste.
