can someone refresh my memory of this disaster?

Factual Questions

I was talking with a guy at work about the coal ash spill and the chemical spill in WV. I was reminded of a flood of some kind happened in the late 90s-early 2000s in which a containment dike holding back a reddish sludge burst. I’m pretty sure it was in Europe, maybe Poland or Romania. That’s all I remember, anyone know what I’m thinking of?

Found it. It was in Hungary. Magyar. It was 2010 so my timeline was way off.

Thanks.
