The U.S.EPA has begun a Removal Action in the Red Valley Chapter of the Navajo Nation. The Site is divided by the AZ/NM stateline. EPA has determined that numerous homesites and structures exhibit elevated levels of gamma radiation. These structures are believed to be contaminated by uranium mining wastes either carried to the sites and used in building material or transported to the sites by natural means. These will be the models for future work this year at remaining contaminated structures in Teec Nos Pos, AZ, Cane Valley, AZ/UT and Tuba City, AZ.
