Livelihoods washed away by toxic spill in Sonora

Between Aug. 6 and 7, about 11 million gallons of copper sulfate acid solution spilled from Cananea’s Buenavista del Cobre mine into the Bacanuchi River, a tributary of the Sonora River. The San Pedro River runs north from Cananea, about 25 miles from the Arizona border, while the Sonora River flows south. The spill contaminated the Bacanuchi and Sonora rivers and left more than 25,000 people in seven counties without water.
Mexican officials called it their country’s worst mining spill in recent history. And then it got worse. More than a month after the spill, heavy rains from Hurricane Odile caused the dams to overflow and the river to swell, soaking nearby fields with toxic water.
