Per-and Polyfluoroalkyl Substances (PFAS) Integrated Science Team

Increasing scientific and public awareness of the widespread distribution of per- and poly-fluoroalkyl substances (PFAS) in U.S. drinking-water supplies, aquatic and terrestrial ecosystems, wildlife, and humans has raised many public health and resource management questions that U.S. Geological Survey's (USGS) science can inform. The USGS Environmental Health Program's PFAS Integrated Science Team...

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...

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)...

Can Spills from Swine Lagoons Result in Downstream Health Hazards?

Livestock manure spills have been shown to result from events such as equipment failures, over-application of manure to agricultural fields, runoff from open feedlots, storage overflow, accidents with manure transporting equipment, and severe weather. Our specialized teams of hydrologists, chemists, biologists and geologists, in collaboration with Johns Hopkins Bloomberg School of Public Health...

Land Stewardship Science Team

The Land Stewardship Integrated Science Team focuses on the potential for contaminant exposures in the environment that might originate from land management activities like wildfire and dust suppression, vector control (for example: mosquitos and rodents) and invasive species (Asian carp and nuisance plants). Perceived health risks to humans and other organisms will be distinguished from actual...
