A waterway in a suburb of Argentina’s capital Buenos Aires turned vibrant purple on Thursday, alarming locals.
The Sarandí Canal flows by way of residential neighbourhoods and industrial areas earlier than reaching an estuary, the Rio de la Plata, which borders an ecological reserve.
Native media stories prompt the color might have been attributable to the dumping of textile dye, or by chemical waste from a close-by depot.
Authorities have taken samples to find out the supply of the contamination.
