Is the waste from the dams toxic?

No. The waste at the dam sites is inert, it has no toxic components. It is mainly composed of silica (sand) from the iron ore processing and contains no chemicals that pose a risk to health. The results of the analyzes requested by Samarco to SGSGeosol Laboratórios, specialized in environmental and geochemical analyzes of soil, attests that the waste from the Fundão dam offers no harm to people or the environment. Samples were collected on November 8th near Bento Rodrigues, Monsenhor Horta, Pedras, Barretos and Barra Longa, in the state of Minas Gerais, and were analyzed according to the Brazilian standard NBR 10004:2004. These sites have been identified for collection for being the closest to the accident, and therefore the samples represent the best material deposited in the dam. After the analyzes, the waste at these sites has been classified as non-hazardous. This means that the analyzed material presents no harm to people and the environment, considering that it provides no contaminants to water, even in rain exposure conditions.

Is the recovery of the Doce River possible?

Yes. The mud from the disruption of the dam has settled mainly in the riverbed of Rio Doce, after passing through Rio Carmo, one of the rivers that form Rio Doce. The other affluents, such as rivers Piranga, Casca, Matipó, Piracicaba, Santo Antônio, Corrente, Caratinga, Suaçuí Pequeno, Suaçuí Grande, Manhuaçu and Guandu, have remained untouched and will be responsible for renovating the water and life of Rio Doce. In an article published on November 18th, on Colabora website, the journalist Agostinho Vieira claims that, contrary to what has been circulating on social networks, the Doce River is not dead and can be recuperated. The text cites some factors that have been causing siltation in the Doce River for years, such as lack of sanitation and deforestation in the region, especially of riparian forests. The report concludes, giving as an example the recuperation of the River Thames in London, which had being considered biologically dead and is now clean. Several federal and state institutions of Espírito Santo have recently formed a governance group to jointly address issues related to the Doce River basin and report on their activities to society. The fist content which is posted brings relevant information about how it is possible to make the Doce River waters potable by treating it with natural flocculants. To learn about this, access
