While the cause is still unknown, authorities are evaluating possible environmental damages, such as discharge from "an unidentified chemical" from the nearby Nadezhda Metallurgical Plant,” CNN reports, citing a statement by Russia's Ministry of Natural Resources and Environment.
Nadezhda Metallurgical Plant is reportedly owned by Norilsk Nickel, the world's largest nickel producer.
So far the company has denied that its plant is to blame for the reddened river.
Norilsk is known for its heavy pollution and is considered one of the most polluted cities on earth.
