Abandoned Uranium Mines Project Atlas Project Overview

چکیده
The Navajo Nation is located on the Colorado Plateau and encompasses over 25,000 square miles across Arizona, New Mexico, and Utah. The distinctive physiography of this region has resulted in a major mining area for uranium. The Navajo Nation includes intensely dissected rocky regions and has elevations that range from about 3,000 feet to slightly over 10,000 feet. The region is known for a wide variety of topographies that include broad upland plains, rugged tablelands with dramatic buttes and mesas, and major mountainous regions. The varied topography results in different climate and vegetation regimes. These include warm, arid desert climates with sparse slow growing grasses and browse plants; intermediate steppe climates with grasses, sagebrushes, and pinyonjuniper; and cold, subhumid mountain climates where pine, oaks, and associated grasses and shrubs are found.

Hibernacula Selection by Townsend’s Big-Eared Bat in Southwestern Colorado
In western United States, both mine reclamations and renewed mining at previously abandoned mines have increased substantially in the last decade. This increased activity may adversely impact bats that use these mines for roosting. Townsend’s big-eared bat (Corynorhinus townsendii) is a species of conservation concern that may be impacted by ongoing mine reclamation and renewedmineral extractio...
متن کاملImpact of uranium mines closure and abandonment on groundwater quality.
The aim of the study is to assess the evolving mine water quality of closed uranium mines (abandoned between 1958 and 1992) in the Czech Republic. This paper focuses on the changes in mine water quality over time and spatial variability. In 2010, systematic monitoring of mine water quality was performed at all available locations of previous uranium exploitation. Gravity flow discharges (mine a...
متن کاملElevated Arsenic and Uranium Concentrations in Unregulated Water Sources on the Navajo Nation, USA
Regional water pollution and use of unregulated water sources can be an important mixed metals exposure pathway for rural populations located in areas with limited water infrastructure and an extensive mining history. Using censored data analysis and mapping techniques we analyzed the joint geospatial distribution of arsenic and uranium in unregulated water sources throughout the Navajo Nation,...
متن کاملUranium mining in Australia: Environmental impact, radiation releases and rehabilitation
The mining and export of uranium and the impacts (and risks) of the nuclear industry have long been a contentious issue in Australia. The ongoing debate primarily relates to the established and potential dangers of ionizing radiation released to the environment from nuclear facilities, such as uranium mines or research reactors. By 2002, three uranium milling projects are operating with a furth...
