"It raises the question: are all of their other tailings dams across the world structurally sound?" Mr Burton said. "This could raise eyebrows about how they are managing the risks at other operations."
There are reports that locals fear the sludge from the dams may be toxic. But Samarco claims the mine waste is "inert".
"It consists mostly by silica [sand] from the iron ore processing and presents no chemical that is harmful to health," the firm's statement said.
Other tailings dams could burst and the owners will claim the sludge is harmless.

Brazil’s national water agency, ANA, has warned that the presence of arsenic, zinc, copper and mercury now present in the Rio Doce make the water untreatable for human consumption.
"Early next week the mudslide is expected to reach the Atlantic, with a potentially devastating impact on the fishing communities along the coast of the state of Espírito Santo."
"On a visit to the affected region on Thursday, President Dilma Rousseff described the incident as “possibly the biggest environmental disaster to have impacted one of the major regions of our country”.
She compared the scale of the damage to the Deepwater Horizon disaster in the Gulf of Mexico, and laid the blame squarely on Samarco."

"It looked like a scene from hell. It even smelled of sulphur,"
"The local schoolmistress became a national heroine, leading all 56 of her young charges in a wild scramble for safety."
"The muddy mass slowly but surely made its way into two river systems, Rio do Carmo and the bigger Rio Doce, in a 500 kilometre journey to the Atlantic Ocean."
"Some 228 municipalities in two Brazilian states (Minas Gerais and Espirito Santo) are located in the Rio Doce basin, many of them affected as the mud slurry travelled down river systems, killing off masses of fish life, causing hydroelectric plants on the route to shut down to protect their turbines from the mud and making the water temporarily undrinkable for hundreds of thousands of residents whose cities draw their water from the system.
According to Samarco, the mudslide for the most consists of sand particles and presents no chemical element harmful to health. According to the Brazilian Institute of Environment and Renewable Natural Resources (IBAMA), the sludge is mainly composed of iron oxide and sand. Local government has collected mud to test if it is toxic or not and results are expected by the beginning of December."
...wait so the misspelling isn't related to Futurama?
Either way, thanks for posting.
Terrible news though. Hope no one else was killed.
"It raises the question: are all of their other tailings dams across the world structurally sound?" Mr Burton said. "This could raise eyebrows about how they are managing the risks at other operations."
. . . investigators are probing reports that Vale contributed to higher water volumes behind the dam by sending waste from one of its nearby mines to Samarco’s tailings pond. When a reporter asked about the reports at the news conference, the executives did not answer.
. . . he delivered a drilling team from a company called Geocontrole to a large wastewater dam run by local iron ore miner Samarco. That was the last he saw of them.
The three men, who told him they were there to conduct tests, were swallowed up the following day by the torrent of mud set loose by the sudden failure of two dams at the site.
As yet, no one has said why the dams failed.
Locals remain cynical about the prospect of reform. "It will all end in pizza," says Mr Oliveira, using the Brazilian saying that means the dispute will lead to no meaningful changes.
