Fluorochemicals are a class of structurally diverse synthetic compounds that contain a carbon-fluorine backbone.
These chemicals were first synthesized nearly a century ago with the discovery of polytetrafluoroethylene (PTFE), and the commercialization of Teflon and Scotchguard. There are thousands of fluorochemicals, including the class of approximately 5,000 – 10,000 per- and polyfluoroalkyl substances (PFAS). These chemicals are used in countless commercial and industrial applications because of their unique physiochemical properties, including oil, water, stain, and fire resistance. PFAS are also resistant to environmental degradation and are therefore often referred to as “forever chemicals”. The extensive usage and environmental persistence of PFAS has resulted in their detection globally in all environmental media.
The mission of SERFN is to:
- Improve the understanding of the environmental fate and transport of PFAS and PFAS-related compounds (e.g., precursors and alternatives);
- Foster interdisciplinary collaborations;
- Increase the awareness of current PFAS research and capabilities in the SER;
- Expand PFAS research opportunities on a regional scale;
- Communicate the latest information on PFAS research;
- Facilitate the development of long-term program strategies within the SER that align with the USGS’s Strategic Science Vision: Integrated science for the study of perfluoroalkyl and polyfluoroalkyl substances (PFAS) in the environment—A strategic science vision for the U.S. Geological Survey (usgs.gov).

Per- and Polyfluoroalkyl Substance Exposure and Effects Research at Columbia Environmental Research Center (CERC)
The Columbia Environmental Research Center’s Per- and Polyfluoroalkyl Substance (PFAS) team conducts research focusing on the occurrence, fate, and toxicity of PFAS compounds in aquatic and terrestrial systems. Laboratory capabilities include dedicated analytical instrumentation and experimental facilities to allow USGS scientists to analyze a wide range of sample types including water, sediment...PFAS Investigations at the Virginia and West Virginia Water Science Center
Exposure to some per- and polyfluoroalkyl substances (PFAS) has been linked to harmful health effects in humans and animals. The Virginia and West Virginia Water Science Center works with local and regional partners to determine the drivers and distribution of PFAS contamination in groundwater, surface water, and drinking water supplies across Virginia and West Virginia.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... - Publications
