On Friday noon, the search and rescue work suspended for the mourning of the victims of the tragedy.
There is an investigation underway into the cause of the dam's collapse, and five people have been arrested including three officials from Vale SA - the company which owns the dam.
Newly released footage shows the moment a dam collapsed in Brazil, sending a river of mud across the nearby town of Brumadinho.
An internal study showed the miner knew as recently as past year that some of the areas swamped with toxic mud were at risk if the dam burst, according to a report by Folha de S.Paulo newspaper. "Vale described the study as a routine disaster preparation plan required by regulators". They were buried under mine waste after the dam collapsed.
"(The study) found that the mine restaurant, where many Vale workers were likely to have died, would be hit by toxic mud.
The mining company said it had also begun safely treating the streets and fields of Brumandinho to prevent the spread of disease as an environmental group told the AP Thursday that it had set out to test the Paraopeba river's levels of toxicity.
Environmental groups accused the previous Congress and president of rolling back significant protections, and many expect further weakening under President Jair Bolsonaro, who has said environmental regulation hamstrings several industries, including mining. "We are in the investigation phase and we can not say whether the (inspection) model was adequate or not".
