"On 4 October 2010 one of the worst toxic spill accidents in Europe of recent years occurred near the city of Ajka in Veszprem County, Hungary, approximately 160 km south-west of Budapest. As a consequence of a failure of the tailing dam of a reservoir for an aluminium production plant alkaline sludge flooded a wide area including three villages. Long-term consequences of the event are not yet known (EEA, 2010)" (Quoted from article)
