Montgomery & Associates is a Tucson-based water resources consulting firm with over three decades of experience supporting mining projects. M&A has developed innovative ways to model dewatering processes, conduct water balances, manage operations using customized monitoring tools, and characterize aquifer conditions under challenging chemical and temperature regimes. We conduct analyses and investigations to support mine feasibility, permitting, and environmental impact studies. M&A’s client list includes most of the world’s major domestic and international mining entities. We employ a group of professionals in our U.S. and South American offices who specialize in hydrology, geology, soil science, policy and regulatory affairs, groundwater modeling, GIS analyses and 3D visualization, database management, and instrumentation and monitoring. Most of our principals have more than 20 years of experience; nearly all have master’s or doctoral degrees, along with one or more professional registrations. M&A staff members frequently present at conferences, participate in professional organizations, and serve on advisory boards.
