Community workers, wearing protective gear, clean a street flooded by toxic mud in the village of Kolontar, Hungary, Thursday, Oct. 7, 2010. The toxic red sludge that inundated three Hungarian villages reached Europe's mighty Danube River on Thursday but no immediate damage was evident, Hungary's rescue operations agency said. The European Union and environmental officials had feared an environmental catastrophe affecting half a dozen nations if the red sludge, a waste product of making aluminum, contaminated Europe's second-longest river after bursting out of a factory's reservoir.
