Authorities in the Arctic city of Norilsk have begun an investigation into a possible pipeline break after a river running through the city turned red. Residents of the nickel-producing city, located in the north east of the country, noticed that the Daldykan River had changed colour on Tuesday (6 September).
Speculation by social media users centred on a possible break in pipes serving the nickel-producing town, leading to industrial waste leaking into the river. Other theories mentioned iron ore seeping into the water through the ground.
In a statement, the natural resources and environment ministry in Russia said that they were probing complaints of unknown chemical pollution, possibly caused by a “break in a Norilsk Nickel slurry pipe”.
