During the fall of 2019, the Department of Homeland Security began pumping large amounts of water from a southern Arizona aquifer to mix concrete for the Trump administration’s border wall. The aquifer is an essential water source for the San Bernardino National Wildlife Refuge, so when the pumping escalated, U.S. Fish and Wildlife officials watched helplessly as the water levels at several ponds — the main habitat for the endangered fish at this Sonoran Desert refuge — dropped “precipitously.”
Since its creation in 1982 the 2,300-acre refuge’s sole mission has been to protect the rare species of the Río Yaqui, including endangered fishes like the Yaqui chub and Yaqui topminnow, and other species, such as the tiny San Bernardino springsnail and the endangered Huachuca water umbel, a plant that resembles clumps of tubular grass. Through a series of artesian wells connected to an aquifer, the refuge has kept ponds filled in this fragile valley for nearly 40 years.
Under normal circumstances, a significant construction project like a border wall would be required to go through an extensive environmental review process as dictated by the National Environmental Policy Act. The Department of Homeland Security says it operates under the spirit of NEPA and solicits public comment.
But with environmental laws — including NEPA, the Endangered Species Act and the Fish and Wildlife Coordination Act — waived for the border wall, the refuge lacks any legal protection, either for itself or the endangered species in its care. So wildlife officials have tried to work with the department, sending hydrological studies and providing recommendations about how to reduce water use near the refuge.
