The pace of mining exploration in Latin America has increased dramatically in recent decades. The Latin American Conference on Compatible Mining, supported by NIEHS, brought attendees from eight North and South American countries to San Luis Potosi, Mexico, to discuss and plan the future of compatible mining — a term coined at the conference.

Compatible mining is defined as the empowerment of communities, civilians, governments, and the private sector to collaborate in a way that minimizes and prevents the environmental and social impacts of mining. Talks at the meeting addressed large-scale and artisanal mining, environmental remediation, community impacts, community outreach, worker health, mining policy and decision making, and mining best practices. The University of Arizona Superfund Research Program, together with the university's Dean Carter Binational Center for Environmental Health Sciences, sponsored the Sept. 8-10 meeting.

Compatible mining in policy and industry operations

The conference established the Pan-American Hub for Compatible Mining to promote best practices for mining operations and to protect human health, the environment, and local culture. The Hub will enable networking among professionals and communities to identify and prioritize pressing issues in mining. A second meeting is planned for March 2016, in Peru.

“The concept of compatible mining is timely with the current pace of mining operations. [The University of Arizona Superfund Research Program], together with their collaborators, is well positioned to develop a hub of information exchange among the Americas,” said Heather Henry, Ph.D., program administrator in the NIEHS Superfund Research Program. “The compatible mining hub exemplifies the NIEHS strategic goal to identify and respond to emerging environmental threats to human health, on both a local and global scale.”

Putting the concepts into practice

In August, as planning for the meeting was underway, a mine wastewater spill contaminated rivers in Cananea, Mexico. Grupo Mexico, which owns the mine, contacted a group of researchers who collaborate through the U.S.-Mexico Binational Center and the University of Arizona Center for Environmentally Sustainable Mining, to evaluate the mid- and long-term impacts of the Cananea Mine spill.

Through collaborations with the Binational Center, the university’s Superfund Research Program will work together with their Mexican colleagues. They will also perform metal analysis for the estimated 12,000 samples that will be generated by these studies. This group of investigators exemplifies the vision for the Pan-American Hub to bring together multiple stakeholders to achieve compatible mining. Grupo Mexico will support studies related to water, soil, and sediment contamination, biodiversity, and human health.

“Grupo Mexico recognizes what a disaster this is and wants us to help define the extent of the contamination now and follow what happens into the future,” said Raina Maier, Ph.D., the university’s Superfund Research Program center director and co-organizer of the meeting. “This team would not be in place and ready to respond if it were not for the NIEHS Superfund Research Program.”
