Willow Spring in Hack Canyon in Arizona north of the Grand Canyon. A sign next to the spring says Water Not Suitable for Drinking. The spring has elevated levels of uranium and selenium. The elevated uranium level is most likely not associated with breccia-pipe uranium mining in the area.

Christopher Fuller is a Emeritus Scientist for the USGS Water Resources Mission Area. His research characterizes processes and mechanisms of metal sorption reactions through field studies and lab experiments to better understand the metal transport and natural attenuation in mine contaminated systems and to better understand geochemical processes affecting bioavailability of metal contaminants to aquatic organisms.

Minerals Science Team
The Minerals Integrated Science Team focuses on contaminant exposures in the environment that might originate from mineral resource activities including, transportation, storage, extraction and waste management. Perceived health risks to humans and other organisms will be distinguished from actual risks, if any. If actual risks are identified the science produced by this team can inform how to...
Study Reveals Processes that Control Uranium Bioavailability in a Freshwater Snail—Relevance to Aquatic Biota in the Grand Canyon Area
Scientists refined an existing speciation model to identify key biogeochemical processes controlling dissolved uranium bioavailability to a freshwater snail. This information is important to advance current understanding and prediction of the ecological risk posed by uranium mining to freshwater ecosystems, including federally managed lands such as in the Grand Canyon area.
