The USGS has collected groundwater chemistry samples since 1981 in the Grand Canyon region to better understand changes in groundwater quality that may be the result of mining activities and to identify "hot spots" with elevated metal concentrations. This manuscript presents results for the assessment of uranium in groundwater in the Grand Canyon region.
