Samarco tailings dam fails at Mariana

The Fundão dam at Samarco, a Vale and BHP joint venture in Brazil, collapsed, killing 19 people and polluting the Doce river. Compensation claims are still being settled years later.

Why it matters. A tailings failure can create liabilities for decades, which is why acquirers now audit dams first.
