INTERA Team Publishes Paper on Deep, Non-Potable Water Supply for Proposed Mine

Albuquerque, New Mexico – Ocotober 30, 2014 –An INTERA team of scientists and engineers, led by Senior Hydrogeologist Peter Castiglia, has published the results of their work on supplying the Ochoa Mine Project (Project) with deep, non-potable water from the Capitan aquifer in southeastern New Mexico, U.S.A. The paper, which is published in the journal Mine Water and the Environment, describes the work that INTERA completed to secure a water supply for a proposed sulphate of potash mine in Lea County, New Mexico that is owned by IC Potash Corp. (ICP).

As the paper describes, the INTERA team identified the deep, non-potable water source, designed, drilled, and tested wells over 5,300-ft deep, and developed a numerical groundwater flow model that was used to evaluate potential impacts of production pumping. The study concluded that the Capitan aquifer is suitable for providing the Project with a high-yield, long-term supply of non-potable water that will not compete with fresh water use by the surrounding community. The results of this work formed the basis of the water supply discussion included in ICP’s NI 43-101 Compliant Ochoa Project Feasibility Study used for Project financing. The conceptual and numerical models develop by INTERA were also adopted by the U.S. Bureau of Land Management as part of completing the Environmental Impact Statement and issuing a signed Record of Decision that authorized the construction and operation of the Project. By supplying the mine with deep, non-potable water, ICP was able to avoid a lengthy permitting process and gain public and regulatory support by safeguarding limited fresh water supplies.

Founded in 1981, Mine Water and the Environment presents original contributions addressing technical questions and practical issues related to the evaluation, prediction, prevention, or control of water problems at mining operations or their impact on the environment. The final publication is available at Springer via http://link.springer.com/article/10.1007%2Fs10230-014-0288-2.
