Uranium mining and the Navajo people
The United States encouraged uranium mining production because of the nuclear arms race with the Soviet Union, its opponent in the Cold War. Large uranium deposits were found on and near the Navajo Reservation in the Southwest, and these were developed through the 20th century. Absent much environmental regulation prior to the founding of the Environmental Protection Agency in 1970 and passage of related laws, the mining endangered thousands of Navajo workers, as well as producing contamination that has persisted in adversely affecting air and water quality, and contaminating Navajo lands.
Private companies hired many Navajo employees to work the mines. Disregarding the known health risks of exposure to uranium, the private companies and the United States Atomic Energy Commission failed to inform the Navajo workers about the dangers and to regulate the mining to minimize contamination. As more data was collected, they were slow to take appropriate action for the workers. Studies show that the Navajo mine workers and numerous families on the reservation have suffered high rates of lung, cancers (including Xeroderma pigmentosum) and other diseases, from environmental contamination. For decades, industry and the government failed to regulate or improve conditions, or inform workers of the dangers. As high rates of illness began to occur, workers were often unsuccessful in court cases seeking compensation, and the states at first did not officially recognize radon illness. In 1990 the US Congress passed the Radiation Exposure Compensation Act, to settle such cases and provide needed compensation.
Despite efforts made in cleaning up uranium sites, significant problems from the legacy of uranium development persist today on the Navajo Nation and in the states of Utah, Colorado, New Mexico, and Arizona. Hundreds of abandoned mines have not been cleaned up, and these present environmental and health risks in many communities. The Environmental Protection Agency estimates that there are 4000 mines with documented uranium production, and another 15,000 locations with uranium occurrences in 14 western states. Most are located in the Four Corners area and Wyoming.
The Uranium Mill Tailings Radiation Control Act (1978) is a United States environmental law that amended the Atomic Energy Act of 1954 and authorized the Environmental Protection Agency to establish health and environmental standards for the stabilization, restoration, and disposal of uranium mill waste. Cleanup has continued to be difficult, and EPA administers several Superfund sites located in the Navajo Nation.

The Navajo people refused to let any industry mine their land in the 1930s, when the appointed federal guardian to the Navajo Nation attempted to decide what mining should take place on their land.
But pressure for mining increased in the postwar years, when the United States believed it had to develop resources to compete with the Soviet Union in the Cold War. In 1948, the United States Atomic Energy Commission (AEC) announced it would be the sole purchaser of any uranium mined in the United States, to cut off dependence on imported uranium. The AEC would not mine the uranium; it contracted with private mining companies for the product. The subsequent mining boom led to the creation of thousands of mines; 92% of all western mines were located on the Colorado Plateau because of regional resources.
The Navajo Nation encompasses portions of Arizona, New Mexico, and Utah, and their reservation was a key area for uranium mining. More than 1000 mines were established by leases in the reservation. From 1944 to 1986, an estimated 3,000 to 5,000 Navajo people worked in the uranium mines on their land. Other work was scarce on and near the reservation, and many Navajo men traveled miles to work in the mines, sometimes taking their families with them.
Between 1944 and 1989, 3.9 million tons of uranium ore were mined from the mountains and plains. In 1950, the US Public Health Service made a massive study of uranium miners. In 1962 it published the first report to show a statistical correlation between cancer and uranium mining. The federal government finally regulated the standard amount of radon in mines, setting the level at .3 WL on January 1, 1969. The Environmental Protection Agency was established on December 2, 1970. But, environmental regulation could not repair the damage already suffered. Navajo miners contracted lung cancer at much higher rates than the rest of the population, and they have suffered higher rates of other lung diseases caused by breathing in radon.
Private companies resisted regulation through lobbying Congress and state legislatures. In 1990, the United States Congress finally passed the Radiation Exposure Compensation Act (RECA), granting reparations for those affected by the radiation. The act was amended in 2000 to address criticisms and problems with the original legislation.
The tribal council and Navajo delegates remained in control of mining decisions before the adverse health effects of mining were identified. No one fully understood the effect of radon exposure for miners, as there was insufficient data before the expansion of mining.
Church Rock uranium mill spill
On July 16, 1979, the tailings pond at United Nuclear Corporation's uranium mill in Church Rock, New Mexico, breached its dam. More than 1,000 tons of radioactive mill waste and 93 millions of gallons of acidic, radioactive tailings solution and mine effluent flowed into the Puerco River, and contaminants traveled 80 miles (130 km) downstream to Navajo County, Arizona. The flood backed up sewers, affected nearby aquifers and left stagnating, contaminated pools on the riverside.
The state contingency plan relied on English-only notification of the largely Navajo public populace affected by the spill. Local residents did not learn immediately of the toxic danger. The locals were accustomed to using the riverside for recreation and herb gathering. Residents who waded in the acidic water went to the hospital complaining of burning feet and were misdiagnosed with heat stroke. Sheep and cattle died en masse. The Navajo Nation asked the governor of New Mexico to request disaster assistance from the US government and have the site declared a disaster area, but the governor refused. This limited the amount of disaster relief the Navajo Nation received.
For nearly two years, the state and federal government trucked in water to the reservation, but ended the program in 1981. Farmers had little choice but to resume use of the river for watering livestock and crops.
Health studies on exposure to uranium
Concerned over the adverse health consequences which Europeans experienced from uranium mines, William Bale and John Harley conducted an independent study. Their work led the US government to start the United States Public Health Study (USPHS) on uranium mine workers. Bale and Harley's studies focused on identifying the level of radon in mines and assessing any correlation with disease, specifically lung cancer. Radon, they found, can attach to mine dust, which would be inhaled and subsequently concentrated in the lung tissue. Because of this action, workers breathed radon gas at concentrations up to 100 times higher than the amount of radon gas indicated. The USPHS was subsequently launched in 1951, with two goals: to identify uranium mine environment exposures, and to conduct a medical evaluation of the miners.
The USPHS study raised ethical concerns. The Navajo workers were rarely notified of the possible dangers which the USPHS was studying. As late as 1960, the USPHS medical consent form failed to inform miners about the possible health risks of working in the mine. The Advisory Committee on Human Radiation Experiments, created in 1994 to explore the treatment of the workers, said: "'Had they been better informed, they could have sought help in publicizing the fact that working conditions in the mines were extremely hazardous, which might have resulted in some mines being ventilated earlier than they were." The USPHS failed to abide by a centerpiece of Nuremberg Code (1947), by failing to have informed consent of the subjects of a research study.
In 1952, the USPHS issued two reports, reporting exceptionally high concentrations of radon in these uranium mines, even higher than those found in European mines years before. Medically, there was little evidence found of sickness. But, the latency from exposure to disease, also found among the European cases, explains why there were few medical effects observed at this early stage. In a private meeting between the AEC and the USPHS, the AEC informed the USPHS scientists that not only could the high radon levels eventually cause cancer, but proper ventilation of the mines could avoid the problem. The government failed to take any action on this finding.
Continued effects and research
The USPHS continued to study the uranium miners, eventually including 4,000 American Indian and non-Indian underground uranium miners. They added miners in 1951, 1953, 1954, 1957 and 1960. In 1962, the USPHS published the first account of the effects of radon exposure. It found a significant correlation between radon exposure and cancer. Additional studies were published in 1968, 1973, 1976, 1981, 1987, 1995 and 1997; these demonstrated linear relationships between radon exposure and lung cancer, a latency period of about 20 years between radon exposure and health effects, and noted that, while smoking tobacco caused a shorter latency period for the development of cancer, it did not fully explain the relationship between radon and cancer. Similar reports found instances of other diseases such as pneumoconiosis, tuberculosis, chronic obstructive pulmonary disease (COPD), as well as diseases of the blood. A 2000 study of the number of cancer cases among Navajo uranium mine workers concluded that the miners were 28.6 times more likely to contract the disease than the study's control group.
Many miners died from radiation-related illnesses. A 1995 report published by American Public Health Association found:
excess mortality rates for lung cancer, pneumoconioses and other respiratory diseases, and tuberculosis for Navajo uranium miners. Increasing duration of exposure to underground uranium mining was associated with increased mortality risk for all three diseases… The most important long-term mortality risks for the Navajo uranium miners continue to be lung cancer and pneumoconioses and other nonmalignant respiratory diseases.
Over the decades, Navajo miners extracted some four million tons of uranium ore, which was used by the U.S. government primarily to make nuclear weapons. Some miners, unaware of the adverse health effects, carried contaminated rocks and tailings from local mines to build their family homes. These were found to be contaminated, with the family at risk. In 2009, those homes began to be demolished and rebuilt under a new government program, which involved temporarily relocating occupants until the homes could be rebuilt.
United States government response
Following the publication of the reports in the early 1950s, some private contractors attempted to properly ventilate their mines. The states of Colorado, New Mexico and Utah established minimum standards for radon concentrations (Dawson and Madsen 2007). But, the AEC was lax in enforcement of the rules; AEC commissioners did not establish national radon standards at the time the studies were released. The AEC said it had no authority to regulate uranium, but it regulated beryllium. The health and activist communities have criticized the AEC for its failure to take action related to the scientific reports. The agency repressed the reports.
Government and uranium industry personnel were privy to the information, but it was not until the 1960s that workers were informed of the environmental dangers. The government response continued to be slow. Regulation of the uranium industry was first debated in Congress in 1966, but little progress was made. Journalists began to publish stories detailing the illnesses of uranium miners, giving them public attention. In 1969, Congress set the standard radon level for mines at .3 WL.
Navajo miners began to file lawsuits to seek compensation for health damages, but often lost in court. But the publicity, presentation of harmful evidence, and victim testimony gave support to their cause.Ted Kennedy (D-MA) was the first senator to propose a Radiation Compensation bill, with the goal of avoiding lawsuits and compensating victims fully, though it was defeated in 1979. Orrin Hatch's (R-UT) 1981 compensation bill was met with a similar fate, and his attempt in 1983 did not reach the Senate floor.
Progress toward legislation
In 1989, Orrin Hatch, supported by fellow Utah Representative Wayne Owens (D-UT), sponsored the Radiation Exposure Compensation Act (RECA), which was signed into law by President George H.W. Bush on October 15, 1990. The Radiation Exposure Compensation Act (RECA): "Offers an apology and monetary compensation to individuals who contracted certain cancers and other serious diseases following their exposure to radiation released during above-ground atmospheric nuclear weapons tests or, following their occupational exposure to radiation while employed in the uranium industry during the build-up to the Cold War."  The United States Department of Justice established regulations for implementing the act, related to individuals eligible for payment, and guidelines for identification, including marriage licenses, birth certificates and official documents, some of which the Navajo did not possess. In some cases, the government did not recognize individual's documentation as legitimate.
With additional data from the studies by the Public Health Service (PHS), in 2000 the act was amended to correct shortcomings: "The RECA Amendments of 2000 broadened the scope of eligibility for benefits to include two new occupationally exposed claimant categories (uranium mill workers and uranium ore transporters), expanding both the time periods and geographic areas covered, and adding compensable diseases, thus allowing more individuals to be eligible to qualify."  As of November 17, 2009, the government has paid claims of 21,810 people, denied 8,789, and paid $1,455,257,096 in reparations.
Abandoned Mine Land program
The Navajo Nation Abandoned Mine Land(s) (NN AML) are numerous United States Environmental Protection Agency-designated "AML sites" on lands of the Navajo people which were used for mining (e.g., uranium). Sites include:
- Abandoned Uranium Mines on the Navajo Nation, Arizona (Site NNN000906087); a region with many of the "521 abandoned uranium mine areas".
- Skyline Abandoned Uranium Mine, Utah; in Monument Valley at Oljato Mesa (the waste piles area has a distinct site number)
- Skyline AUM Waste Piles (NN000908358)
- Northeast Church Rock Mine, New Mexico (NECR, NNN000906132); "mostly on Navajo tribal trust land", "the highest priority abandoned mine cleanup in [sic] the Navajo Nation", and a site which adjoins the United Nuclear Corporation (UNC) uranium mill Superfund site "on private fee land".
"During the late 1990's, portions...were closed by the Navajo Nation Abandoned Mine Land program".
This specific Superfund site for the AUMs on Navajo land has been in existence since 1994. This is following many years of research on the health effects of uranium mining which eventually led to the Radiation Exposure Compensation Act in 1990. Since its acceptance as a Superfund site, many federal, tribal, and grassroots organizations have come together to assess and remediate contamination sites on the Navajo Nation. Due to the fact that there are hundreds of contaminated sites, there have been a few big successes and many communities stuck in limbo. The following is a history of this Superfund site, the organizations that have collaborated on this environmental remediation, and recent criticisms of the handling of this large and complicated problem.
The Abandoned Uranium Mines on the Navajo Nation were established as a Superfund site in 1994 in response to a Congressional hearing brought by the Navajo Nation on November 4, 1993. This hearing included the Environmental Protection Agency (EPA), the Department of Energy (DOE), and the Bureau of Indian Affairs (BIA). Superfund status stems from the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA) which allows the United States federal government to assign funds for environmental remediation of uncontrolled hazardous waste sites. The Navajo Nation is located in Region 9 (Pacific Southwest) of the Superfund which serves Arizona, California, Hawaii, Nevada, the Pacific Islands, and Tribal Nations. The site's official EPA # is NNN000906087 and it is located in Congressional District 4. According to the EPA's Superfund site overview, other names for the AUMs may include "Navajo Abandoned Uranium Mines" or "Northeast Church Rock Mine." Church Rock Mine is one of the EPA's most successful clean-up sites among over 500 sites spanning the 27,000 square mile Navajo Nation.
Nearly four years after the initial Congressional hearing, the EPA announced their first helicopter survey for the AUMs in September 1997. Located in the Oljato area in Southeastern Utah near the Utah-Arizona border, this was first of several helicopter surveys that aimed to measure "naturally occurring radiation (gamma radiation) coming from abandoned uranium mining areas." The stated purpose of these surveys was to "determine if these sites pose a risk to the people in the area and if so, what measures should be taken to minimize that risk."
Over ten years later, on June 9, 2008, the EPA announced its five-year plan for the clean-up of uranium contamination on the Navajo Nation. This five-year plan contained nine specific objectives for 2008-2012: assess up to 500 contaminated structures and remediate those that pose a health risk; assess up to 70 potentially contaminated water sources and assist those affected by it; assess and require cleanup of AUMs via a tiered ranking system of high priority mines; clean Church Rock Mine, the highest-priority mine; remediate groundwater of abandoned uranium milling sites; assess the Highway 160 site; assess and clean Tuba City Dump; assess and treat health conditions for populations near AUMs; and lastly to summarize the action of the Nuclear Regulatory Commission (NRC) in its assistance to the Navajo Nation's cleanup efforts. Since the introduction of the five-year plan, the EPA has released a progress report (available online) each consecutive year. As of August 2011, the EPA lists its accomplishments as: screening 683 structures, sampling 250 unregulated water sources and shutting down 3 such contaminated sources, provision of public outreach and educational programs for safe water practices, instituting a 2.6 million dollar water hauling feasibility project, and providing up to 386 homes with clean drinking water through a 20 million dollar project with Indian Health Services. For 2012, the EPA has listed its next steps as replacing 6 contaminated structures, demolishing other contaminated structures, and continuing screening of these structures for referral to the EPA's Response Program. The 2011 progress report also lists Church Rock, the Oljato Mesa, and the Mariano Lake Mine as sites of current or proposed remediation.
According to the EPA's website, the AUM Superfund site is not on the National Priorities List (NPL) and has no proposals to be put on this list. The NPL is the list of hazardous Superfund sites that are deemed eligible for long-term environmental remediation. The EPA suggests that although NPL listing is a possibility it is "not likely" for the abandoned uranium mines on the Navajo nation. NPL status guides the EPA in its decisions on sites to further investigate, a process that has been criticized for the handling of these mines. With over 500 uranium sites and only a few sites slated for full-scale remediation plans, the prioritization process has recently been called into question by The New York Times (see Recent Press).
Superfund works with many agencies from both the federal government and the Navajo Nation in order to properly assess and direct funding to mining sites. These agencies include: the Navajo Nation Environmental Protection Agency (NNEPA), the Indian Health Services (IHS), the Diné Network for Environmental Health (DiNEH), the Navajo Nation Department of Water Resources (NNDWR), the Department of Energy (DOE), and US Nuclear Regulatory Commission (NRC). The NNEPA was established in 1972 and officially recognized through legislation as a separate regulatory branch of the Navajo Nation in 1995. With the official acceptance of the NNEPA also came the adoption of the Navajo Nation Environmental Policy Act. According to the NNEPA website, their mission is: "With respect to Diné values, to protect human health, land, air and water by developing, implementing and enforcing environmental laws and regulations with a commitment to public participation, sustainability, partnership, and restoration." (Diné is the word for Navajo in the traditional Navajo language) NNEPA consults with the US EPA on site assessments (the US EPA is the lead agency for the Site Assessment Project). NNEPA helps the EPA in assessing and deciding which contaminated structures should be demolished and which water sources should be deemed a human health risk. The two also collaborate to perform community outreach for the Navajo people whose lives are affected by the uranium mining. The Center for Disease Control and the DiNEH Project are also integral players in the assessment of water quality and community outreach. The Navajo Nation Department of Water Resources, with funding from the EPA, assist Navajo residents by hauling water for residents near 4 contaminated water sources, a 2.6 million dollar project. Indian Health Services helped fund the 20 million dollar drinking water project started in 2011. This project serves 386 homes near 10 contaminated water sources. The NNEPA, IHS, NNDWR, and DiNEH project have been the main partners with the US EPA in water hauling projects.
Community involvement and response
Forgotten People (FP) is a grassroots organization incorporated on the Navajo Nation which represents the health and well-being of the residents of the Navajo Nation in Arizona. The full name of this organization is Forgotten People Diné Bé Iina' na' hil naa, meaning Diné Rebuilding Communities. Forgotten People began as a political organization dedicated to advocacy for the Navajo people against forced relocation plans which spanned 1974 to 2007. When forced relocation programs were ended in 2007, the organization shifted focus to a broader variety of issues with a focus in environmental remediation. In 2009, Forgotten People received the Environmental Excellence Award from the NNEPA. Forgotten People was an integral aspect of the Black Falls water project, which involved collaboration with the US EPA to provide clean drinking water and educational outreach for the Black Falls community which was affected by uranium mining. FP attributes the success of Black Falls with the evolution "from a needs-based or dependency approach to the agencies into an assumption of full responsibility for their own development." The Black Falls community was able to decide upon their own solutions for their water problems. Their efforts were coordinated by FP and funded by the US EPA. Forgotten People represents an evolving grassroots community which is moving simply from organizing to actually empowering residents to take their development into their own hands.
Forgotten People also gathers and displays pertinent public records for a variety of issues facing the Navajo on their website. For their campaigns against uranium mining, their website displays all official responses US attempts at relaxing uranium restrictions on Navajo territory. FP also preserves the response of the President of the Navajo Nation in response to proposals for uranium mining near the Grand Canyon. In 2005, the President of the Navajo Nation, Joe Shirley, Jr., signed the Diné Natural Resources Protection Act which banned uranium mining and processing on Navajo land. After signing the law, President Shirley stated, "As long as there are no answers to cancer, we shouldn't have uranium mining on the Navajo Nation. I believe the powers that be committed genocide on Navajo land by allowing uranium mining. "
Criticism and press
Despite the EPA's claims of a "strong partnership with the Navajo Nation," recent articles have been published that call into question the equitability and efficiency of the EPA's action on the abandoned uranium mines. On March 31, 2012, The New York Times published an article entitled "Uranium Mines Dot Navajo Land, Neglected and Still Perilous" by Leslie MacMillan. The article suggests that politics and money are influencing the prioritization of mine clean-up efforts. David Shafer, an environmental manager at the United States Department of Energy, has said that questions of whether current uranium problems are due to past mining or to the naturally occurring mineral are delaying the process of cleaning up. Similar concerns are common in environmental remediation projects for victims of industrial pollution.
While the EPA does prioritize mines that are nearest to people's homes, MacMillan highlights some remote locations where people do live and yet have been neglected by the EPA. Cameron, Arizona is one such site which has a population of nearly 1000. Rancher Larry Gordy stumbled across an abandoned uranium mine on his grazing land for his cattle near Cameron in the summer of 2010. There are still no warning signs in the town of Cameron to alert people of potential contamination. On December 30, 2010 Scientific American published an article entitled "Abandoned Uranium Mines: An 'Overwhelming Problem' in the Navajo Nation" by Francie Diep. Diep told Gordy's story and reported that the EPA assessed his site on November 9, 2010. Diep suggested that this date was moved up due to publicity of Gordy's story; originally the EPA had promised to visit within six months of his original discovery of the uranium mine.
Similar allegations of prioritization due to negative publicity for the EPA were made of the Skyline Mine in the Oljato Mesa. Elsie Begay, a 71-year-old Navajo woman from the Oljato region was the topic of a series of articles in The Los Angeles Times in 2006. These articles were written by Yellow Dirt: An American Story of a Poisoned Land and a People Betrayed (2010) author Judy Pasternak, whose work on these articles led to her book. One EPA representative, Jason Musante, stated this publicity "might have bumped the site up the priority list."
Over a year after Gordy stumbled across the mine in his cattle's grazing land, MacMillan reports that the site at Cameron has yet to be given a priority by the EPA. When EPA officials were asked to accompany a reporter to the Cameron site, the officials declined and instead offered to visit the newly cleaned site in Oljato. MacMillan spoke with a Navajo hotel manager near the Skyline Mine who expressed hesitation about the EPAs remediation, stating, "That's what they want you to see: something that's all nice and cleaned up." MacMillan drew attention to the fact that cows are grazing on contaminated land and people are eating these cattle. Taylor McKinnon, a director at the Center for Biological Diversity, went so far as to say the site was the "worst he had seen in the Southwest." Although the locally grown beef is tested, standard tests for meat do not include checking for radioactive substances like uranium. The EPA has put an emphasis on health effects throughout its five-year plan, so the lack of any sort of attention in this matter has raised eyebrows.
In addition to the questioning of political bias in the prioritization of mining sites, there is criticism of the EPA's decision to revisit a 1989 permit proposing to mine for uranium near Church Rock. New Mexico's KUNM radio station reported on May 9, 2012 that Uranium Resources Incorporated has expressed interest in starting production near Church Rock by the end of 2013. An online petition has already gained nearly 10,000 signatures against this new mining initiative.
Beginning in the 1960s, uranium miners were beginning to become ill with cancer at increasing rates. The state of Utah did not recognize radiation exposure at the time as a category of illness, making workers compensation unattainable for many of the sick Navajo (Dawson and Madsen 2007). Private industry's treatment of the Navajo workers was poor, according to recent standards: companies failed to educate workers on precautionary measures, did not install sufficient engineering controls, such as adequate ventilation; and did not provide sufficient safety equipment to protect workers to the known dangers related to the mines. The Navajo were never told of the radiation effects, and did not have a word for it in their language. Many Navajo did not speak English and trusted the uranium companies to have their interests in mind. Navajo workers and residents have felt betrayed as the results of the studies became known, as well as the long delays by companies and the US government to try to prevent the damage, and to pay compensation. Lung cancer became so prevalent among the Navajo people that working in uranium mines was banned on Navajo lands in 2005.
Allegations of racism
White workers also faced different conditions: Navajo workers were forced to enter the mine directly after a detonation, while it was filled with dust and smoke. However, the white workers were able to stay behind. Navajo miners were paid less than miners from off-reservation, well below minimum wage. Until radon exposure safety standards were imposed by the Secretary of Labor Willard Wirtz over the objections of the Atomic Energy Commission and the uranium mining industry in June, 1967, mines lacked ventilation, exposing workers to radon.
Widows of mine workers met to discuss their grief; they started a grassroots movement that eventually reached the Congressional floor.
The Church Rock uranium mill spill raised claims that race was a factor in the federal government's paying little attention to the disaster:
When there was a relatively minor problem at Three Mile Island in Pennsylvania, the entire attention of the Nation was focused on this location and the Federal and State assistance brought to bear to deal with it was extraordinary. When the largest release of radioactive material in the history of the United States occurs in Navajo country, however, the attention paid to it by the Federal and State authorities is minimal at best.
Many residents of the Navajo Nation have anxiety and concerns about the future because of large amounts of radioactive waste remaining. One Navajo Elder explains: "We, the elderlies, that resides around here don't know what was good and worst about the uranium. There were several deaths in this area that was affected by radiation or cancers. We need help. I lost my wife last year [to cancer] and now I am 87 years. My wife would have been 70 years old which made a lot of difference. I am lonely and can't get anywhere without her help. I was hurted and miserable." The number of cancer cases has continued to rise because of these conditions, as water, air and ground generally have been affected. In areas near uranium mills, residents suffer stomach cancer at rates 15 times those of the national level. In some areas, the frequency gets as high as 200 times the national average. Hundreds of abandoned uranium mines with exposed tailings remain unremediated in the Navajo Nation area posing a contamination hazard. Near the former uranium mills, water contamination and contamination of rocks which many residents used to build their houses, continue to be problems.
A 1995 report published by American Public Health Association found: "excess mortality rates for lung cancer, pneumoconioses and other respiratory diseases, and tuberculosis for Navajo uranium miners. Increasing duration of exposure to underground uranium mining was associated with increased mortality risk for all three diseases… The most important long-term mortality risks for the Navajo uranium miners continue to be lung cancer and pneumoconioses and other nonmalignant respiratory diseases." That is to say, not stomach cancer, which the Navajo people naturally have a higher rate of experiencing than the national US average.
Since 1994, the Environmental Protection Agency (EPA), along with the Navajo Nation Environmental Protection Agency, has been mapping areas affected with radioactivity. In 2007, they compiled an atlas of the abandoned uranium mills in order to rid the area of nuclear waste. In 2008, the EPA implemented a five-year cleanup plan, focusing on the most pressing issues: contaminated water and structures. The EPA estimates that 30% of all Navajo people lack access to uncontaminated drinking water.
The EPA is targeting 500 abandoned uranium mills as another part of their five-year cleanup plan, with the goal of ridding the area of nuclear waste. Its priority was identification of contaminated water sources and structures; many of the latter have been destroyed and removed. In 2011, it completed a multi-year project of removing 20,000 cubic yards of contaminated earth out of the reservation, near the Skyline Mine, to controlled storage on the plateau.
In 2017, a $600 million settlement attempts to clean up 94 abandoned uranium mines.
