PFAS Transport, Exposure, and Effects

The team is determining the movement and behavior of per- and poly-fluoroalkyl substances (PFAS) from their sources in the environment, as they move through exposure pathways in ecosystems including watersheds and aquifers, their incorporation into food webs, and molecular to population scale effects on fish and wildlife. These studies are accomplished at a variety of spatial scales from regional...

Large Fraction of Unidentified Organofluorine in a Coastal Watershed has Implications for River to Marine Ecosystems

A group of scientists investigated per- and polyfluoroalkyl substances (PFAS) in watersheds on Cape Cod and identified a unique signature for aqueous film forming foams (AFFF) from legacy firefighting and fire training. A combination of statistical modeling and laboratory measurements indicates that unidentified organofluorine constitutes a large fraction of PFAS in the river systems that...

Is Uranium in Water Resources near the Grand Canyon a Health Hazard?

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)...

Food Resources Lifecycle Integrated Science Team

The team studies the movement of toxicants and pathogens that could originate from the growing, raising, and processing/manufacturing of plant and animal products through the environment where exposure can occur. This information is used to understand if there are adverse effects upon exposure and to develop decision tools to protect health.

Disaster Science

Natural (coastal storms, wildfires, floods) and human-induced (structural failures, building collapse, oil, and/or chemical spills) disasters occur every year in the United States. Minimizing loss of human life and damages to personal property and infrastructure is the focus of most disaster response and preparedness activities by federal, state, and local communities. However, the potential for...
