Deadly Brazil dam collapse was disaster waiting to happen
SAO PAULO — Lax regulations, chronic short staffing and a law that muffled the voices of environmentalists on mining licenses made the devastating collapse of a dam in southeastern Brazil all but destined to happen, experts and legislators say.
The failure of the dam holding back iron ore mining waste on Jan. 25 unleashed an avalanche of mud that buried buildings and contaminated water downstream. At least 115 people have died, and another 248 people remain missing.
But one of the cruelest parts of the tragedy in Brumadinho is that it has happened before: In 2015, mining dams burst in nearby Mariana in what is considered Brazil’s worst environmental disaster.
