Mystery behind why ponds turned 'poisonous' pink
Residents are bewildered as to why two reservoirs in their town have turned a bright shade of pink.
The two adjacent reservoirs in the Kinelskiy district of the city of Samara, in southwest Russia, have changed colour and are now a vivid shade of pink – sparking concern from locals in the area.
Investigations are now ongoing into how the radical change happened, with concerns a local industrial outlet has polluted waters.
Five industrial units are nearby, including a concrete factory, a compound feed plant, a brewery, a refinery and a pig farm.
“It is clear right away that there is some poison in there. There is no such synthetic colour in nature,” resident Alexey Veretennikov said.
Ecologist Sergey Simak, who is looking into the issue, has named three possible reasons for the change of colour.
He said it could be down to chemical contamination, the dissolution of coloured underlying rocks in the water and the development of algae and bacteria that has in turn produced red pigments.

“I wonder what do these producers use for making beer if the waste leaves such a colour,” Vladimir Afonin said online.
