(HUNGARY) -- Hungary is experiencing an "ecological catastrophe" as toxic sludge containing a unique combination of deadly toxins flows from an aluminum plant toward the Raba and Danube Rivers.
The incident was set off when a dam burst at a local metal processing plant.
"When I heard the rumble of the flood," said one resident, "I only had time to jump out of the window and run to higher ground."
Four people are known to have died while between 80 and 90 people were taken to the hospital Tuesday night with chemical burns.
Additionally, almost 500 police officers and soldiers, including six emergency detection teams, have been deployed.
To prevent further flooding, plaster has been poured into the Marcal River in an effort to bind the sludge.
