Church Rock is a census-designated place (CDP) in McKinley County, New Mexico, United States. The population was 1,128 at the 2010 census. Church Rock is named for Church Rock, a prominent natural landmark with the same name.
The Navajo Nation, also known as Navajoland, is a Native American reservation in the United States. It occupies portions of northeastern Arizona, northwestern New Mexico, and southeastern Utah; at roughly 17,544,500 acres, the Navajo Nation is the largest land area held by a Native American tribe in the U.S., exceeding ten U.S. states. In 2010, the reservation was home to 173,667 out of 332,129 Navajo tribal members; the remaining 158,462 tribal members lived outside the reservation, in urban areas, border towns, and elsewhere in the U.S.. The seat of government is located in Window Rock, Arizona.
Superfund is a United States federal environmental remediation program established by the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA). The program is administered by the Environmental Protection Agency (EPA). The program is designed to investigate and clean up sites contaminated with hazardous substances. Sites managed under this program are referred to as "Superfund" sites. There are 40,000 federal Superfund sites across the country, and approximately 1,300 of those sites have been listed on the National Priorities List (NPL). Sites on the NPL are considered the most highly contaminated and undergo longer-term remedial investigation and remedial action (cleanups).
The Kerr-McGee Corporation, founded in 1929, was an American energy company involved in oil exploration, production of crude oil, natural gas, perchlorate and uranium mining and milling in various countries. On June 23, 2006, Anadarko Petroleum acquired Kerr-McGee in an all-cash transaction totaling $16.5 billion plus $2.6 billion in debt and all operations moved from their base in Oklahoma, United States.
An Indian reservation is an area of land held and governed by a federally recognized Native American tribal nation whose government is accountable to the U.S. Bureau of Indian Affairs and not to the state government in which it is located. Some of the country's 574 federally recognized tribes govern more than one of the 326 Indian reservations in the United States, while some share reservations, and others have no reservation at all. Historical piecemeal land allocations under the Dawes Act facilitated sales to non–Native Americans, resulting in some reservations becoming severely fragmented, with pieces of tribal and privately held land being treated as separate enclaves. This jumble of private and public real estate creates significant administrative, political and legal difficulties.
Radium and radon are important contributors to environmental radioactivity. Radon occurs naturally as a result of decay of radioactive elements in soil and it can accumulate in houses built on areas where such decay occurs. Radon is a major cause of cancer; it is estimated to contribute to ~2% of all cancer related deaths in Europe.
Uranium in the environment refers to the science of the sources, environmental behaviour, and effects of uranium on humans and other animals. Uranium is weakly radioactive and remains so because of its long physical half-life. The biological half-life for uranium is about 15 days. Normal functioning of the kidney, brain, liver, heart, and numerous other systems can be affected by uranium exposure, because uranium is a toxic metal. The use of depleted uranium (DU) in munitions is controversial because of questions about potential long-term health effects.
Uranium mining in the United States produced 173,875 pounds (78.9 tonnes) of U3O8 in 2019, 88% lower than the 2018 production of 1,447,945 pounds (656.8 tonnes) of U3O8 and the lowest US annual production since 1948. The 2019 production represents 0.3% of the anticipated uranium fuel requirements of the US's nuclear power reactors for the year.
Uranium mining in Arizona has taken place since 1918. Prior to the uranium boom of the late 1940s, uranium in Arizona was a byproduct of vanadium mining of the mineral carnotite.
In-situ leaching (ISL), also called in-situ recovery (ISR) or solution mining, is a mining process used to recover minerals such as copper and uranium through boreholes drilled into a deposit, in situ. In situ leach works by artificially dissolving minerals occurring naturally in a solid state. For recovery of material occurring naturally in solution, see: Brine mining.
Uranium mining in New Mexico was a significant industry from the early 1950s until the early 1980s. Although New Mexico has the second largest identified uranium ore reserves of any state in the United States, no uranium ore has been mined in New Mexico since 1998.
The Midnite Mine is an inactive uranium mine in the Selkirk Mountains of the state of Washington that operated from 1955 to 1965 and again from 1968 to 1981. Located within the reservation of the Spokane Tribe of Indians, it is approximately 8 miles (13 km) from Wellpinit, Stevens County. The mine was listed as a Superfund site under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA) on May 11, 2000. In addition to elevated levels of radioactivity, heavy metals mobilized in uranium acid mine drainage pose a potential threat to human health and the environment.
Tar Creek Superfund site is a United States Superfund site, declared in 1983, located in the cities of Picher and Cardin, Ottawa County, in northeastern Oklahoma. From 1900 to the 1960s lead mining and zinc mining companies left behind huge open chat piles that were heavily contaminated by these metals, cadmium, and others. Metals from the mining waste leached into the soil, and seeped into groundwater, ponds, and lakes. Because of the contamination, Picher children have suffered elevated lead, zinc and manganese levels, resulting in learning disabilities and a variety of other health problems. The EPA declared Picher to be one of the most toxic areas in the United States.
The Navajo Boy (1950s) was a silent film that portrayed the Cly family on the Navajo Nation in Monument Valley, Utah. The director, Robert J. Kennedy, narrated the film live at each showing. In addition, he provided little written information about the context or the identities of the Navajo people featured in the film.
The Church Rock uranium mill spill occurred in the U.S. state of New Mexico on July 16, 1979, when United Nuclear Corporation's tailings disposal pond at its uranium mill in Church Rock breached its dam. The accident remains the largest release of radioactive material in U.S. history, having released more radioactivity than the Three Mile Island accident four months earlier.
In the 1950s, the Navajo Nation was situated directly in the uranium mining belt that experienced a boom in production, and many residents found work in the mines. Prior to 1962, the risks of lung cancer due to uranium mining were unknown to the workers, and the lack of a word for radiation in the Navajo language left the miners unaware of the associated health hazards. The cultural significance of water for the Navajo people and the environmental damage to both the land and livestock inhibits the ability of the Navajo people to practice their culture.
The uranium mining debate covers the political and environmental controversies of the mining of uranium for use in either nuclear power or nuclear weapons.
The International Uranium Film Festival was founded in 2010 in Rio de Janeiro, and has traveled to Germany, Portugal, India and the United States. This educational event merges art, ecology, environmentalism and environmental justice, to inform the public about uranium mining and milling, nuclear power issues, nuclear weapons and the nuclear fuel cycle from "cradle to grave" life-cycle assessment - and the effects of radioactivity on humans and other species. The festival founders and principal organizers are Norbert Suchanek and Marcia Gomes de Oliveira. The legal organizer of the International Uranium Film Festival is the arts and education non-profit "Yellow Archives". The organizers and the festival participants seek to educate and activate the international public on these issues through the dynamic media of film and video.
Nuclear labor issues exist within the international nuclear power industry and the nuclear weapons production sector worldwide, impacting upon the lives and health of laborers, itinerant workers and their families.
The 2015 Gold King Mine waste water spill was an environmental disaster that began at the Gold King Mine near Silverton, Colorado, when Environmental Protection Agency (EPA) personnel, along with workers for Environmental Restoration LLC, caused the release of toxic waste water into the Animas River watershed. They caused the accident by breaching a tailings dam while attempting to drain ponded water near the entrance of the mine on August 5. After the spill, the Silverton Board of Trustees and the San Juan County Commission approved a joint resolution seeking Superfund money.
