Mining Hydrogeology and Impact Assessment Services

Since its inception, MMA has provided hydrogeologic consulting services to mining and related industries. MMA analyses have been used to establish ground-water extraction rates for mines, minimize the potential for depletion from surface-water bodies, and support negotiations with state and federal regulators.

Barrick Goldstrike Mines Inc. - Elko, Nevada
MMA has provided technical guidance for the control of groundwater in the largest open-pit gold mine in North America.
Proposed Zinc and Copper Mine, Crandon, WI
MMA completed a review of groundwater modeling which predicted the impact to sensitive surface water bodies.
Site Reviews for Mining Companies Worldwide
McDonald Morrissey Associates has assisted mining companies evaluate potential sites around the world.

Other Representative Projects

  • Proposed Coal Strip Mine, Castle Valley, Utah –- Conducted a study to determine the effects of a proposed coal strip mine on groundwater levels in the Ferron Sandstone Aquifer near Emery, Utah. The work involved an extensive data collection effort that included test-drilling, aquifer testing, borehole geophysics, stream gaging and development of a three-dimensional flow model to predict effects of the proposed mine on ground-water levels the sandstone aquifer.
  • Pipeline Tunneling Impact Assessment, Columbus, Ohio — MMA assisted Eagon and Associates, Inc. in the development of a groundwater flow model to assess the affect de-watering associated with interstate pipeline tunneling.
