CANANEA, Mexico — Authorities in northern Mexico have issued a new alert of a toxic spill in the Sonora River basin from a copper mine operated by Grupo Mexico, the state director of civil protection said Sunday. The agency is urging some 25,000 residents of the area to avoid using the water 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 the tributaries affected drain into the Bacanuchi River.
