The Center for Biological Diversity (CBD) contacted Integrated Hydro Systems, LLC and requested Robert Prucha review available studies and evaluate assess potential impacts of the proposed Rosemont Mine, located southeast of Tucson on the Las Cienegas National Conservation Area to the east of the mine (see Figure 1). CBD indicated that both the Bureau of Land Management (BLM) and the Environmental Protection Agency (EPA) have both expressed concerns that the proposed Rosemont mine will capture groundwater which directly sustains surface water flows in the nearby Las Cienegas National Conservation Area (LCNCA) wetlands and Cienega Creek.
