The public is concerned that uranium in natural geologic formations, mine tailings, dusts, water, and other geologic materials can pose a health hazard to humans and wildlife.
Our specialized teams of hydrologists, chemists, and geologists working together at a field site in the Grand Canyon region of the United States have shown:
Elevated uranium concentrations (above the drinking water standard) were found at Pigeon Spring in the Grand Canyon area. However our science showed these uranium concentrations are naturally elevated and not related to nearby mining operations.
Questions We're Working On:
Is uranium in springs and wells elsewhere originating from natural or mining-related sources?
Are humans, fish, or wildlife in the Grand Canyon area or elsewhere being exposed to elevated uranium in water, dusts, or other geologic materials from natural or mining-related sources?
If so, do these exposures to natural uranium or uranium in mining byproducts actually pose a health hazard, and how can hazardous exposures to mining byproducts, if present, be better minimized or prevented?
Below are other science projects associated with this project.

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...
