The former Pigeon Mine in northern Arizona is seen here looking towards the northeast.
Uranium levels in Pigeon Spring, just north of the Grand Canyon, are likely due to a natural source of uranium and not related to the nearby former Pigeon Mine, according to a recent study by the USGS.
Donald Bills
Don joined the USGS Arizona Water Science Center in 1978 and is currently a Scientist Emeritus.
Donald Bills is a Scientist Emeritus with over 34 years of experience in basic data programs and projects studying the surface water, groundwater, and water chemistry of Northern Arizona and the western US. Don’s recent works include regional groundwater flow and contaminate hydrology (uranium and trace metals) of the Grand Canyon watershed, geohydrology of large regional flow systems in Northern Arizona, and groundwater-resources assessment and development support for Tribal Lands in Northern Arizona.
Don’s special interests are in large regional groundwater-flow systems and regional springs. Don has an interest in borehole and surface geophysics.
Professional Experience
In 2009, Don was appointed to a national team developing observation well and streamflow-gaging station abandonment guidelines for the American Reinvestment and Recovery Act.
In 2011, Don was selected as a team member for the Energy and Minerals Mission Area Strategic Science Planning Team.
Education and Certifications
BS, Physical Science, California State University-Chico, 1976.
