The Navajo Nation produces most of the energy for the southwest, but many Navajo homes lack sanitation and piped water. In 1966 the US government imposed a 43-year Bennett Freeze on more than 1.6 million acres denying all infrastructure repairs or construction. Only 3 percent of the families in these communities have electricity and only 10 percent have running water (HR5168, 2004). During the “freeze,” more than 100 million tons of mill tailings accumulated in the Four Corners area of the southwest. These mill tailings contain radium and thorium with a half-life of 80,000 years. Superfund reports 520 abandoned uranium mines on the Navajo Nation with 25% of the unregulated sources in the western Navajo reservation exceeding drinking water standards for kidney toxicants, including uranium.
