These data are comprised of measurements of aluminum, iron, cobalt, nickel, copper, zinc, arsenic, selenium, molybdenum, silver, cadmium, thallium, lead, bismuth, thorium, uranium, and mercury in invertebrates, vegetation, and small rodents. Gross alpha activity, gross beta activity, and radionuclide activities (isotopic U, isotopic Th) are also presented for vegetation; radioactivities for small rodents were previously presented at https://doi.org/10.5066/P9HARTQ4. Histopathology results are given for liver and kidney lesions generally associated with metals toxicoses in small rodents. Samples were collected at the Pinenut Mine (active mining) and Arizona 1 Mine (post-production) in the Grand Canyon watershed....

This data package contains the final combined field sampling data collected by the USGS July 2013 and July-August 2015 at three active uranium mines (Canyon Rim Mine, Pinenut Mine, and Arizona 1 Mine) as well as two reference sites (Little Robinson Tank and EZ2 Pipe) in northwestern Arizona. Vegetation and soils were assessed by using line-point intersect (LPI) methods and estimates of plant species richness. In addition, triplicate tissue samples for three functional groups (graminoids, forbs, and shrubs) were collected at plots around each site to be analyzed for tissue contaminant concentrations. There are three separate shapefiles depicting A) Point locations for the mine study sites (the center of the mine...

This data release includes elemental analysis of soil samples collected at breccia-pipe uranium mines, at one undeveloped breccia-pipe uranium deposit, and at a reference site in northern Arizona. Samples were collected near the Arizona 1, Canyon, Kanab North, and Pinenut uranium mines, over the EZ2 breccia-pipe uranium deposit, and at the Little Robinson Tank reference site. Samples were collected around the Arizona 1 mine after active mining had ceased during July 2015; around and within the mine yard at the Canyon mine during mine-development activity and before active mining occurred in June 2013; around and within the mine yard at the Kanab North mine during reclamation and before reclamation was completed...
