The Sarandí stream that winds through the dense outskirts of Buenos Aires, Argentina, has recently turned blood red, leading to fears of a potential industrial chemical leak. Local authorities are investigating the stream’s change in color following initial reports on Feb. 6.
Located near Villa Inflamable in Avellaneda, nine miles south of the Argentine capital, the stream runs alongside tanneries and other industries that use chemicals to turn animal skins into leather. Residents quickly uploaded photos of the crimson stream to social media, spurring fears of the cause of the color change.
