Uranium Mining in the Southwest in Navajo Nation, USA

As of 2005, the Navajo Nation has banned uranium mining on their land. However, due to the large supply of uranium under the Navajo Reservation companies have been trying to re-open mines. Liabilities remain.


The lands of the Navajo Nation include 27,000 square miles spread over three states, Utah, Arizona and New Mexico. The geology of these lands makes them rich in uranium, a radioactive ore in demand after the development of atomic power and weapons at the close of World War II. From 1944 to 1986, nearly four million tons of uranium ore were extracted from Navajo lands under leases with the Navajo Nation. Many Navajo people worked the mines, often living and raising families in close proximity to the mines and mills. Today the mines are closed, but a legacy of uranium contamination remains, including over 500 abandoned uranium mines (AUMs) as well as homes and drinking water sources with elevated levels of radiation. Potential health effects include lung cancer from inhalation of radioactive particles, as well as bone cancer and impaired kidney function from exposure to radionuclides in drinking water (U.S EPA). The Navajo people, due to a language barrier and limited education, were largely isolated from the flow of knowledge about radiation and its hazards [1]. Mobilization began in reaction to several mill spills and continuing health effects from mine tailings. While there was resistance, those being affected were not listened to and did not have adequate resources to create a large opposition. As journalist Judy Pasternak recounts, a few outstanding individuals - among them Navajo schoolteacher Lorissa Jackson, former Interior Secretary Stewart Udall, his son Tom (now Sen. Udall, D-N.M.), and U.S. Rep. Henry Waxman - helped raise awareness and made a stand against one of the grossest cases of betrayal and willful oversight in the history of the country.  Another voice in the fight against this injustice was Harry Tome, a tribal council member and later employee of the minerals department of the tribe, was one of those who noticed the problem in the early 1960s. In 1973, Tome prompted the Albuquerque Tribune to run a cover story that led to the first legislation in the U.S. Congress aimed at compensation focused on benefits for uranium miners. The bill never passed but in 1978, Tome began working with Udall who filed two lawsuits in 1979 seeking damages for uranium miners [1].

Other Health impactsAccording to the EPA, potential health effects include lung cancer from inhalation of radioactive particles, as well as bone cancer and impaired kidney function from exposure to radionuclides in drinking water.
Socio-economical ImpactsVisible: Loss of landscape/sense of place, Loss of livelihood, Loss of traditional knowledge/practices/cultures, Violations of human rights, Lack of work security, labour absenteeism, firings, unemployment

Briefly explain:No, the effects of decades of mining have caused significant health effects as well as poverty and loss of cultural/traditional land. The threat of uranium mining continues despite actions by the Navajo Nation to protect their land and people from the effects of uranium mining.
