Water in the Navajo Nation currently has an average of 90 micrograms per liter of uranium, with some areas reaching upwards of 700 micrograms per liter.[6] In contrast, the Environmental Protection Agency (EPA) considers 30 micrograms per liter the safe amount of uranium to have in water sources.[7] Health impacts of uranium consumption include kidney damage and failure, as kidneys are unable to filter uranium out of the bloodstream.[8] There is an average rate of End Stage Renal Disease of 0.63% in the Navajo Nation, a rate significantly higher than the national average of 0.19%.[9]
The U.S. Environmental Protection Agency (EPA) has been cleaning up uranium mines in the Navajo Nation since as part of settlements through the Superfund since 1994. The Abandoned Mine Land program and Contaminated Structures Program have facilitated the cleanup of mines and demolition of structures built with radioactive materials.[10] Criticisms of unfair, inefficient treatment have been made repeatedly of EPA by Navajos and journalists.[11][12][13]
