Europe: Hungary’s tide of toxic sludge

Hungary’s worst environmental disaster was set off when the wall of a storage reservoir containing liquid waste from an aluminum processing plant collapsed, disgorging nearly 1 million cubic meters of highly corrosive red mud.

“Nothing can be done to save Kolontár,” said Budapest’s Népszabadság. On Oct. 4, the wall of a storage reservoir containing liquid waste from the Ajka aluminum processing plant in western Hungary collapsed, disgorging nearly 1 million cubic meters of toxic red sludge, which soon inundated nearby villages. The red tide crushed homes, damaged bridges, and even sucked cars clear out of their garages. The village of Kolontár was directly in the path of the deluge; four people died there, including a 3-year-old child. Hungary’s prime minister, Viktor Orbán, who visited on Thursday, declared it had become “impossible for people to live here.” Instead, he promised to build a new settlement and a memorial.

This is Hungary’s worst environmental disaster, said The Economist. At least eight people died and 120 were injured—many suffering severe burns after being trapped in the highly corrosive mud, which can “strip off the top layer of skin.” All life in nearby streams and rivers died immediately. Efforts to prevent the poison from reaching the Danube River have been partially successful: Dams were built in tributaries and vast amounts of vinegar and gypsum were poured into the water to neutralize the alkalinity. Even so, huge quantities of toxins, including mercury and arsenic, have been flushed into the Danube basin, and the 15 square miles of mostly agricultural land that was inundated will be unusable indefinitely.
