A Russian nickel company has taken responsibility for a spillage that caused a local river to turn blood red overnight. On 6 September, social media channels were flooded with images of the crimson Daldykan River near Norlisk, an industrial city in northern Russia. Coined the river of blood, many were quick to place the blame for the striking colour change on effluent from a local metal factory. Norlisk Nickel, the plants owner, played down any suggestions of an industrial leak, even posting images on 8 September of a seemingly clean Daldykan river. Following pressure from environmental groups and Russian environment officials, however, the company has now acknowledged there was a spill. Heavy rainfall on 5 September led to wastewater escaping from a filtration dam at the plant, according to Norlisk. The company claim the waste contained iron salts, which turned the river red. Norlisk insists the spillage presents no hazards for people or river fauna. Russias environment ministry has now launched an investigation into the leak and its potential impact.
