Hungarian factory sorry for those killed by sludge

Kolontar: The owners of the metals plant whose reservoir burst, flooding several towns in western Hungary with caustic red sludge, expressed their condolences on Sunday to the families of the seven people killed, as well as to those injured — and said they were sorry for not having done so sooner.

MAL Rt, which owns the alumina plant in Ajka, also said it was willing to pay compensation "in proportion to its responsibility" for the damage caused by the deluge.

But the trouble may not be over.

With the northwest corner of the storage pool still showing a hole 50 meters (yards) wide where the mix of mud and water broke through last week, officials said the collapse of at least one of the breached walls was inevitable. That, they said, would probably unleash a new deluge of toxic matter that could ooze a half-mile (1 kilometre) to the north, wreaking further havoc.

That would flood parts of the town nearest the plant — one of those already hit by the industrial waste October 04 — but stop short of the next town to the north.

Environmental State Secretary Zoltan Illes said that recently discovered cracks on the northern wall of the reservoir at the alumina plant have temporarily stopped widening because of favourable weather conditions but will continue to expand, especially at night.

Disaster agency spokesman Tibor Dobson said engineers didn't detect any new cracks overnight on Saturday, and the older cracks were being repaired, but it was too soon to consider lowering the state of alert.

Protective walls were being built around the reservoir's damaged area to hold back further spills. And a 2,000-foot- (620-meter-) long dam that will be between 4 and 5 meters (yards) high was under construction to save the areas of the town of Kolontar not directly hit by last week's toxic flood.

"I would describe the situation as hopeful, but nothing has really changed," Dobson said. "The wall to protect Kolontar is planned to be finished by tonight, but it will likely be several days before residents may be able to move back."

Nearly all of Kolontar's 800 residents were evacuated on Saturday, when Prime Minister Viktor Orban said the north wall of the massive storage pool — which is 24.7 acres (10 hectares) in size — was "very likely" to collapse because cracks that had appeared at several points.

The roughly 6,000 residents of neighbouring Devecser, just north of Kolontar, were told by police on Saturday to pack a single bag and get ready to leave at a moment's notice.

"This hasn't changed," Dobson said. "We are still on guard in case of any more spills."

Illes said that, since it would be impossible to transfer the 2.5 million cubic meters (568 million gallons) of red sludge still in the damaged reservoir anywhere else, he had set a two-month deadline for closing up the huge opening.

"The hole is 50 meters (yards) wide and 23 meters high," Illes said. "The job, including pouring enough concrete to raise three 10-storey buildings, will have to be done from the air. This is unprecedented."

Red sludge is a byproduct of the refining of bauxite into alumina, the basic material for manufacturing aluminium. Treated sludge is often stored in ponds where the water eventually evaporates, leaving behind a largely safe red clay. Industry experts say the sludge in Hungary appears to have been treated insufficiently, if at all, meaning it remained highly caustic.

Illes, commenting to reporters during a tour of the affected villages and the damaged reservoir, confirmed that the red sludge stored in Hungarian reservoirs had not been treated to reduce its alkalinity.

A five-member European civil protection team will start work in Hungary, helping to assess and advise on the impact of the sludge on the environment, in particular on agricultural land, surface and underground water supplies, and the flora and fauna. The team will also anticipate risks and suggest solutions about how to restore nature as well as the agricultural and urban land affected.
