  After the catastrophic rupture of a mine-tailings dam in Brazil last week, leaving behind at least 110 dead, 238 missing and an environmental disaster of epic proportions, the police were quick to arrest five people who had been responsible for inspecting the dam and who most recently proclaimed it “stable.” Certainly they had erred, and courts will decide whether they did so criminally. But rounding up the usual suspects does not begin to address responsibility for a disaster of this scale and a danger many mining communities face around the world.

  Tailings are the wet waste from mining operations, often laced with toxic chemicals. At thousands of mines around the world, millions of tons of the muck accumulate behind dams. The most common type of dam — and the cheapest to build — is known as “upstream,” made by piling up thick sludge and raising the height of the dam as the pond grows. At the mine where the accident occurred in southeastern Brazil, owned by the giant mining company Vale, the dam was 28 stories high.

  The danger posed by tailings dams is well known. Three years ago another upstream dam in the same Brazilian state, Minas Gerais, and co-owned by Vale and Australia’s BHP Group, collapsed, killing 19 people. The muck from that mine flowed 400 miles to the Atlantic Ocean. Other dams have collapsed in many countries around the world, and while the overall number of failures each year has been declining, the occurrence of major collapses has increased. According to the database World Mine Tailings Failures, there were 46 “serious” or “very serious” collapses — such as those in Brazil — between 1998 and 2017.

  One reason is increased rainfall because of climate change, which can erode a dam wall years after the tailings pool is no longer in use. One study found that heavy rain was cited as a contributor to a quarter of global dam failures. Given that there are thousands of tailings dams around the world, and that mining companies generate ever more waste — they produced 8.5 billion metric tons in 2017, more than double the amount in 2000, according to an Australian researcher — the dams pose a danger that arresting a few workers won’t address.

  The cost of failures is high, as Vale is learning. Shares in the company plunged 24 percent on the Monday after the Friday accident, and Vale is likely to face billions of dollars in penalties. That cost alone should propel Vale and the rest of the mining industry to take an immediate look at the way that they dispose of mining sludge and to inspect their dams. A joint report in November 2017 by the United Nations Environment Program and the Norwegian foundation GRID-Arendal found that in most failures, there had been ample advance warning signs. “The tragedy is that the warning signs were either ignored or not recognized by under-resourced management,” the report said.

  After the 2015 accident in the state of Minas Gerais, state and federal investigators urged hiring more dam inspectors. But the federal government slashed budgets, in effect leaving Vale and other companies to do their own monitoring. It’s far from certain that the government will do better this time: Brazil’s new right-wing president, Jair Bolsonaro, has already hobbled environmental regulators, and his infrastructure minister has warned against the “demonization” of Vale.

  Vale, by contrast, has been quick to pledge changes. Fabio Schvartsman, its chief executive, said Tuesday that the company had decided to stop operations at mines where another 10 upstream dams were still in use until all were fully decommissioned, a process likely to take one to three years. The dam that burst last week had been out of use for two and a half years, he said, and was in the process of being decommissioned.

  The global mining industry should take heed. It is clear that the industry needs to take a close look at upstream dams, to establish strict international standards for the way they are built and inspected and to study alternative ways to dispose of their wastes.
