Kathleen Tsosie of Farmington, New Mexico describes growing up tending sheep with her grandparents and playing in the small desert town of Cove, Arizona. From the 1940s through the 1980s, The Lukachukai and Carrizo Mountains in the Navajo or Diné Nation in northeastern Arizona were the site of dozens of uranium mines. In 2014, the Environmental Protection Agency entered a legal settlement of $1 billion to assess the environmental damage and clean up mines that were operated by Kerr-McGee Corporation and its successor, Tronox. Because of high levels of uranium in the drinking water, wells can no longer be used for households, livestock, or agriculture. The area was connected to municipal water sources 25 years ago. The Diné Nation is a Native American reservation within the United States.
