Center for Environmentally Sustainable Mining (CESM)

Mission Statement:

The University of Arizona Lowell Institute for Mineral Resources (IMR) focuses on education and research in the areas of mineral exploration and exploitation. In 2011, the IMR developed an environmental pillar that addresses issues associated with the environmental sustainability of mining and the management of legacy mining sites. The Center for Environmentally Sustainable Mining (CESM) was initiated using seed funding from the Technology Research Initiative Fund Water Sustainability Program (TRIF-WSP). The mission of CESM is to develop educational and research initiatives that address environmental issues related to mining activities in arid and semi-arid environments. Examples of research initiatives include the development of novel technologies to improve the revegetation efficiency of mine waste materials, minimize water use, suppress dust generation during mining operations, and assess short- and long-term health risks from contaminated water and air in urban environments near legacy and active mining operations. Educational initiatives include community engagement programs focused on evaluating exposure risks in population centers adjacent to active mining operations or downstream from historic sites affected by acid-mine drainage.


The US is one of the largest global consumers of mineral resources and Arizona is ranked first among states in the value of non-fuel mineral resources produced each year. Innovative approaches are critically needed for sustainable mineral resource development in the US in the 21st century or this development will not happen.  In addition, the CESM research and educational initiatives provide critical training for undergraduate and graduate students as future members of a well-trained workforce, key to sustainable mineral resource development. Seed funding provided by CESM facilitates the development of new research initiatives by UA faculty focused on mining sustainability.

Focal Areas:

  • Revegetation and ecosystem regeneration
  • Dust characterization and control
  • Water use efficiency and control of groundwater contamination
  • Remediation of legacy mine wastes including fate and speciation of contaminant metal(loids)
  • Fate and speciation of metal(loid)s in mining waste
  • Citizen science; Community engagement for risk assessment of environmental exposures associated with legacy mine waste and active mining operations
  • Community teach-ins to facilitate community response among indigenous communities impacted by mining and contamination from legacy mine sites

CESM Technical Advisory Committee:

A technical advisory committee (TAC) meets regularly to help prioritize and develop the educational and research mission of CESM. The TAC is composed of members from the environmental divisions of major mining industries and consulting firms. Representatives from both hard rock mining and rock products industries are included in the TAC.
