This was the tiny Hungarian village of Kolontar one year ago.<br/> Its streets were filled with toxic red sludge, which burst through a reservoir at a nearby factory.<br/> The torrent killed 10 and injured 120 - making it Hungary's worst ecological disaster.<br/> Now, exactly one year on, Kolontar has largely been rebuilt.<br/> But residents, many of whom were forced from their homes, are still struggling to come to terms with what they lost.<br/> (SOUNDBITE) (Hungarian) RESIDENT JOZSEF HOLCZER, SAYING:<br/> "I cannot forget it. It's impossible to erase it from my mind. Those who were not here and did not live through it cannot imagine what it was like. Unfortunately I know."<br/> It was in October 2010 that this holding pond outside an alumunium factory ruptured.<br/> Sludge quickly swept over three towns, leaked into rivers and covered acres of farmland.<br/> The company that owns the factory -Hungarian Aluminum - was fined 632 million U.S. dollars and several employees are under investigation.<br/> But environmental activists say there are dozens of other toxic waste dumps across Eastern Europe and the potential for another disaster remains.<br/> (SOUNDBITE) (English) GREENPEACE CAMPAIGNER BALAZS TOMORI, SAYING:<br/> "There is no guarantees still that a next Kolontar, another toxic waste problem can occur in the Carpathian Basin. Not only in Hungary but in the region, in the ex-Socialist bloc. The region is full of toxic waste deposits, legal or illegal, which can mean threat to environment and people."<br/> To help with cleanups like this, Hungary has suggested the European Union create a special fund. Officials say they would need up to 7 billion euros to get it going.<br/> Andrew Raven, Reuters
