Problem Description / Relevance to Water Security:
On October 4, 2010 the embankment of the red mud reservoir failed and released a mixture of 600-700 thousand cubic meters of red mud and water. The mud, a byproduct of refining aluminium from bauxite ore, was dangerously alkaline, extremely salty and contained potentially toxic metals like chromium and vanadium. Lower parts of the settlements of Kolontár, Devecser and Somlóvásárhely villages were flooded. Ten people died, and another 120 people were injured. The red mud flooded 800 hectares of surrounding areas.
