Authorities in northern Mexico have issued a new alert of a river spill from a copper mine operated by Grupo Mexico, the state director of civil protection said Sunday.
The agency is urging people to avoid using water from the Sonora River after local municipalities complained of a toxic plume, said Carlos Arias, civil protection director for the border state of Sonora, where the spill occurred.
Arias said a flyover of the area shows an abnormal orange stain. He said his department is taking measures to ensure people don't come in contact with the water until it can be . . .
