On Aug. 6, 2014, after heavy rainfall, 10 million gallons (40 million liters) of acidified copper sulfate flooded from a waste reservoir at Buenavista mine into the Sonora and Bacanuchi rivers, slightly below 62 miles (100 kilometers) from the border metropolis of Nogales, Sonora.
After the spill, Grupo México first agreed to present 1.2 billion pesos (about $68 million) to a restoration fund, however in 2017 that belief was closed and the remaining funds returned to the mining firm, PODER claims.

Adrián Pedrozo Acuña, director normal for the Mexican Institute for Water Know-how, stated the air pollution had additionally impacted the area’s ingesting water. “The outcomes offered right here present very clearly that there’s a security or well being drawback within the water the inhabitants consumes,” he stated.
Franco, who lives within the close by metropolis of Hermosillo, stated this brings essentially the most urgency for communities by which many can not afford to purchase bottled water.
Because the spill, Buenavista del Cobre has continued to function — and grown in measurement. Within the years instantly earlier than the accident manufacturing elevated threefold, based on Pedrozo.
