Tisza+Q4

Tisza disaster How did it happen? A deadly cocktail of cyanide and heavy metals, leaked from the Sasar waste pond near Baia Mare, Northern Romania, into a nearby creek. The poisonous liquid then ran into the Szamos, a tributary of the Tisza River, and then reached the Tisza on 4 February.

Who or what cause the problem? Ida Miro Kiss blamed the disaster on the eco-colonialist attitude of the Australian owners of Aurul, the company whose operation caused the spill. "They take away their gold, and leave us the poison."

Why did it happen? All three waves of poisonous heavy metals entered the waterway following a break in a retaining wall at Borsa, Romania. People reports spoke that there two separate breaks. On Wednesday that there was only one rupture in the sump tank wall in Borsa. During a recess in the talks, Deputy State Secretary for Water Management Bela Hajos, who is heading the Hungarian delegation, reported that he had been told by the Romanian delegation that the gap in the retaining wall had been closed off on 13 March. The lead level of the first wave, measured at Tiszafured, which is about midpoint on the Hungarian section, was five times over the maximum permissible level. Below the reservoir at Kiskore, also about midpoint, the polluted water spread over a larger area, which diluted the concentration of contaminants.
