Abstract The Atlas Mill Tailings Pile is located adjacent to the Upper Colorado River near Moab, Utah. Milling of ore ceased in 1984 and the Atlas Corporation subsequently declared bankuptcy. The U.S. Department of Energy (USDOE) is the current manager of the site and is evaluating cleanup options that include remediation for groundwater at the site. This reach of the Upper Colorado River was declared as critical habitat for two endangered fish species (Colorado pikeminnow, Ptychocheilus lucius; and razorback sucker, Xyrauchen texanus) by the U.S. Fish and Wildlife Service (USFWS) because it is one of the few existing areas that contains known spawning and rearing habitats for these fishes. Monitoring data indicates that the groundwater entering the Upper Colorado River is contaminated with ammonia, metals, and radiochemicals. The USFWS is concerned that contaminated groundwater from the Atlas Mill Tailings Pile may be impacting endangered fish populations within the critical Habitat.
