Navajo Nation Abandoned Uranium Mine Point Scores

Uranium (Nuclear Minerals) / Exploration, Mining, Marketing, & Acquisitions

This is a point shapefile of Abandoned Uranium Mine (AUM) centroids developed from AUM Polygons (NN_AUM_Poly_Surf.shp) on or within one mile of the Navajo Nation.Minimal attributes from NN_AUM_Poly_Surf.shp are maintained, including primary and alias mine names, and MAP_ID. HRS scores developed for air, water, surface water, groundwater, and total are joined to this centroid point shapefile. This dataset covers the six Abandoned Uranium (AUM) Regions of the Navajo Nation.

This dataset was developed to support the U.S. Environmental Protection Agency (USEPA) in its undertaking of an extensive scientific study to determine if abandoned uranium mines (AUM) and related mine features pose a significant risk to human health and the environment, and to identify areas requiring action to reduce risk for the Navajo Nation.

There are 9 thematic attributes for this AUM Point Scores dataset:
• Mine ID - arbitrary, unique identifier assigned to each of the AUM site.
• Mine_Name - Primary mine name.
• Aliases - Alias or secondary mine names.
• Map_ID - provides a generally northwest to southeast sequential numeric scheme
across the whole of the Eastern AUM Region for presentation in maps of the Eastern
AUM Region Screening Assessment Report
• Air_Score - Air Pathway Scores
• Soil_Score - Soil Exposure Scores
• SWtr_Score - Surface Water Pathway Scores
• GWtr_Score - Groundwater Pathway Scores
• TotalScore - Combined (sum total) Pathway/Exposure Scores

See the Metadata Process Steps for more information about the development of the AUM attributes.
