This paper explores the legacy of uranium mining and environmental injustice in Monticello, Utah, and the surrounding area. Focusing on the Monticello Mill as a case study, it examines how the U.S. government knowingly exposed rural and Indigenous communities to radioactive contamination under the guise of national security and economic progress. Drawing on historical documents, environmental justice theory, and community health data, the paper reveals patterns of environmental racism, institutional neglect, and the offloading of toxic risk onto marginalized populations. Ultimately, it calls for accountability and systemic change, recognizing the potential for environmental advocacy and global solidarity to reshape the future.
