Cronkite News – WASHINGTON — The Environmental Protection Agency said Thursday it will award contracts worth up to $220 million to three companies for the cleanup of some of the hundreds of abandoned uranium mines on the Navajo Nation.
Work could start later this year following the completion of assessments for mining sites coordinated between the EPA and the Navajo Nation’s environmental agency, the federal agency said.
This week’s announcement is just the latest in years of efforts to clean up the mines, the toxic legacy of Cold War mining in the region. More than 30 million tons of uranium ore were mined in the region, according to the EPA, which said more than 500 mines were ultimately abandoned.
“From World War II until the end of the Cold War, millions of tons of uranium were mined on Navajo lands, exposing mine workers and their families to deadly radiation,” said Rep. Tom O’Halleran, D-Sedona, whose district includes the Arizona portion of the Navajo Nation.
“As a result, high rates of cancer, birth defects, and contaminated water sources remain a reality for residents of the Navajo Nation even now,” O’Halleran said in a statement on the contracts.
