A wave of caustic red sludge had just poured in over the back fence and was descending rapidly over the backyard, smothering chickens and hares as well as a garden of flowers, peppers, grapes and tomatoes. It rose up until it covered the tiled front porch and leached in through the front door, dyeing the pristine white lace curtains red. Mr. Holczer, 34, escaped with burns on his feet from the dangerous muck.
The origin of the liquid was a nearby sludge reservoir holding the leftovers of the process that converts bauxite to aluminum. For more than 25 years, residents say, a Hungarian manufacturer, MAL Rt., the Hungarian Aluminum Production and Trade Company, has stored such waste at several artificial storage ponds in the region. Once a state-owned company, it was privatized in the 1990s like much of Communist-era industry in Eastern Europe.
Just after noon on Monday, a corner of the sludge reservoir broke, sending the goo into the surrounding countryside, turning four prosperous, picturesque villages into red-tinged towns out of science-fiction horror films.
The mud drowned at least four people and sent more than 100 to hospitals with burns, caused by a highly alkaline caustic substance. Sixteen square miles are covered in the muck, hundreds of residents suffered mild burns or lung irritations, and many animals were killed.
Residents here are still waiting for officials to release their analysis of the sludge’s chemical content. A dangerous pollutant at best because of its corrosive nature, red mud from the aluminum production process can contain heavy metals and low-level radioactivity, ingredients that can cause health problems like cancer, and in the long term it can contaminate the environment.
The sludge poured into local streams, which now all appear to be tinted with henna, and is moving downstream at about a mile an hour. It is headed for the Raba River, which empties into the Danube. It has already killed all the river life in the local rivers and streams but now threatens a broad international environmental disaster if high concentrations of the sludge get downstream.
So far the damage is limited to Hungary, which has not asked the European Union for assistance in responding to the catastrophe, but Joe Hennon, the European Commission’s spokesman for environmental issues, said that the organization was concerned about the sludge or its elements moving where it could affect other countries.
“There is potential for widespread environmental damage,” Mr. Hennon said. “Right now, they’re trying to contain it, to stop it from reaching the Danube.”
The mud is normally regulated as a pollutant in Europe but can be classified as a hazardous substance if levels of toxic elements are high, he said.
