Aspects of uranium mining that are not well understood

This illustration by USGS water data specialist Ben Siebers highlights aspects of uranium mining that are not well understood on a background of hikers ascending the southern rim of the Grand Canyon. Questions such as how does dust move uranium and other elements off mine sites throughout the mine life cycle, what are the effects of uranium and other elements on animals not yet studied, and what is the source of uranium found in springs and groundwater? The USGS continues studies with partners to answer these questions.
