Pollution and water scarcity from the Quellaveco mine in Peru’s Moquegua department have killed wildlife, hurt the local economy, and created health problems in communities, according to a new investigation by several advocacy groups.The mine is operated by Anglo American Quellaveco S.A., a subsidiary of British mining company Anglo American, and is expected to produce around 300,000 tons of copper on average until the end of the decade.Studies have found high levels of metals, arsenic and mercury in human testing and water assessments. The company maintains the readings don’t exceed the standards for drinking and vegetable irrigation.

A copper mine in southern Peru that took decades to complete environmental assessments has been contaminating local watersheds with harmful metals, critics say. In its first few years of operation, the mine has allegedly endangered wildlife, threatened the local economy, and created health concerns in communities.

Developers of the Quellaveco mine in Peru’s Moquegua department spent more than 20 years conducting and revising environmental assessments to responsibly extract copper and molybdenum, a metal used in industrial alloys. But after the mine started operating in 2022, the impacts from pollution, erosion and other issues became difficult to ignore, residents say.
