The Samarco Dam Collapse

The Samarco Dam CollapseThe Biggest Brazilian Environmental DisasterIntroduction When a natural catastrophe happens, it forever and a day catches the attention of people around the world. Therefore, this research was the place where breeding was collected about the greatest environmental cataclysm that occurred in the history of Brazil, which affected the lives of many an(prenominal) Brazilians. This report aims to show the damage caused to the population and the environment, besides the neglect of these large companies with the populationMethodologyThis report is constituted of research and collection of information of countersign, and informatory reports about the biggest environmental disaster in the history of Brazil.The DisasterOn November 5, 2015, the greatest environmental disaster occurred in the history of Brazil. This tragedy occurred at the itty-bitty historic town of Mariana in the interior of the state of Minas Gerais. The Fundo dam, which was the responsibility o f the mining connection Samarco, failed, causing the leakage of approximately 62 meg cubic meters of mud from the tailings, a huge tsunami In total 19 people died, hundreds of buildings were destroyed and left families homeless. The largest volume leakage of material dumped by dams of mining rejects of all time, also caused the pollution of the Doce river and environmental damage that extended to the states of Esprito Santo And Bahia. (O Globo,2016)The village that was destroyed by the mine collapse(The Argentina Independent,2016)The mudslide tsunami reached 39 cities in three Brazilian states. As a result of this disaster more than than 11 tons of fish were killed. The fauna and flora in the Rio Doce Basin became pull down more vulnerable. Ecosystem and species already threatened by predatory activities, impacts from industry, agriculture and mining are now at risk of extinction.(O Globo, 2016)The ResultsSamarco is controlled by Vale and the Australian company BHP Billiton, w hich accounts for 2% of the world production of pellets (steel balls used in steel production), is also one of the largest exporters in Brazil. (News.com.au, 2016)The Fundo dam used the hydraulic landfill system. The anterior reports showed that the main hypothesis for the accident, according to experts, is that a liquefaction (process has occurred, rather than Ejecting, retaining water), leading to the transformation of the sand into mud and a sudden variation in the internal coerce of the tailings deposit, making it unable to contain the waste. Shortly before the accident, the University of So Paulos Seismology Center (USP) recorded four small earthquakes. (O Globo, 2016)Almost a year later on the disaster, a re-issue was announced with the possible causes of the breach of the reservoir, BHP commercial director Dean Dalla Valle said there is no evidence that anyone had put production ahead of safety or reason to believe that someone from BHP had indicated that the dam was in d anger.The purpose is to determine the cause of the failure and not blame, (News.com.au, 2016) said Dalla Valle, denying that BHP or Vale had information about the prospects for a disaster.Youre not hiding any of it its there for all to see. (News.com.au, 2016)In the report, it was found that the rupture of the dam was caused by structural defects that prevented drainage. Despite the results, Samarco denies irregularities. It is comport that despite the results presented the company remains concerned about its own profits rather than being worried about predicting future disasters.According to The Argentina Independent, the 76 pages of the report showed that the dam rupture was caused by problems in the drainage project. Furthermore a small earthquake on the day the dam also could project accelerated the failure, according to the report. Besides that a separate police investigation also accused mining company Samarco of intentional misconduct, claiming the company ignored signs th at a dam was at risk of collapse.Samarco has already been fined 250m reals (64m) by Ibama (Brazilian Institute of Environment and Renewable Natural Resources) and 112m reals (28m) by Semad (Minas Gerais state goernments environment agency). (News.com.au, 2016)ConclusionEven the disaster had occurred in the Rio Doce basin affecting a small part of a country as big as Brazil the disaster is far from over for the people living in those places. Douglas Krenak explains Those affected continue to suffer, public health is precarious, The social system is precarious, its going down, this tragedy is creating problems now and it will create more in the future( The Argentina Independent, 2016).Although this story is far from over, what is expected to be responsible for the damage to the population and the environment. So that in the future the companies will invest more in the development of new technologies in their works foreseeing a greater security so that disasters like this one never hap pen again BibliographyThe shielder (2016, October15) Samarco dam collapse one year on from Brazils worst environmental disaster Retrived February 27,2016, fromhttps//www.theguardian.com/sustainable-business/2016/oct/15/samarco-dam-collapse-brazil-worst-environmental-disaster-bhp-billiton-vale-miningO Globo(2016, November 11) Maior desastre ambiental do Brasil, Tragdia de Mariana deixou 19 mortos Retrived February 27,2016, fromhttp//acervo.oglobo.globo.com/em-destaque/maior-desastre-ambiental-do-brasil-tragedia-de-mariana-deixou-19-mortos-20208009The Argentina Independent(2016, april 7) The Forgotten tragedy Revisiting Brazils Worst Ever Retrived February 28,2016, fromhttp//www.argentinaindependent.com/currentaffairs/analysis/revisiting-brazils-worst-ever-environmental-disaster/Insurance Journal(2016, august 30) Brazil Mine Disaster Caused by Poor Drainage Design of Tailings Dam Report Retrived February 28,2016, fromhttp//www.insurancejournal.com/news/international/2016/08/30/4247 81.htmNews.com.au(2016, september 1) BHP on fatal Brazil dam burst report Were not hiding any of it Retrived February 29,2016, fromhttp//www.news.com.au/technology/environment/bhp-on-fatal-brazil-dam-burst-report-were-not-hiding-any-of-it/news-story/562524fb559f21f4180b171da7009098
