A second chemical spill has taken place at a North American mine, withMexico’s Procuraduría Federal de Protección al Ambiente (PROFEPA, attorney general for environmental protection) ordering Grupo Mexico subsidiary Southern Copper to make “full remediation” for a 1.4 million cubic feet spill of sulfuric acid into the Bacanuchi River.
Authorities imposed restrictions on the water supply to several towns and cities in northwest Mexico after the spill allegedly turned the water orange. The National Water Commission said it was monitoring chemicals in the Bacanuchi and Sonora Rivers following the spill at the Buenavista copper mine in Cananea, south of the U.S. border in Arizona.
Impacted towns include Arizpe, Banamichi, San Felipe de Jesus, Aconchi, Baviacora, Ures and the Sonora state capital, Hermosillo.
Sonora is Mexico’s leading producer of gold, copper and graphite and other mined products.
