On March 9, 2015, the U.S. Geological Survey (USGS) presented their results from Task 4: USGS Review of Boundary Condition Test Documentation during a meeting with the Coronado National Forest (CNF), U.S. Fish and Wildlife Service (FWS), and SWCA Consultants. The purpose of Task 4 was to perform a peer review of the documentation of a series of tests on the possible effects of selected boundary conditions in two numerical groundwater models for the Rosemont Copper project. In evaluating the test results, the USGS identified three topical areas that would substantively improve the groundwater models’ capacity to simulate inherent uncertainty in the groundwater system.
