Understanding the Dynamics of Per- and Polyfluoroalkyl Substances (PFAS): Insights from USGS Research
The USGS Environmental Health (EH) Program research where per- and polyfluoroalkyl substances PFAS are found, how they move and change in the environment, how they might affect both ecosystems and human health, and ways to reduce their impact. The three teams focusing on these issues within the EH Program include: 1) the PFAS Integrated Science Team, 2) the PFAS Core Technology Team, and 3) the...
Environmental Health: Science to Support Natural Resource Use
The Environmental Health Program integrates multi-disciplinary research to tackle the environmental challenges that impact the nation's natural resource assets. By providing comprehensive research and data, the program assesses both actual and perceived risks associated with environmental contaminants and pathogens while supporting variety of uses of our natural resources.
Natural Solutions for Reducing PFOS Pollution in Our Environment
Per- and polyfluoroalkyl substances (PFAS) are a group of over 14,000 different man-made compounds that are widely used in various industrial and consumer products and linked to various health issues. Perfluorooctanesulfonic acid (PFOS) is a persistent synthetic chemical within the PFAS group, recognized for its widespread use and persistence in the environment. The U.S. Geological Survey is...
Innovative Sensor Development for Detecting Low-Micrometer Plastics in Freshwater Systems
Plastic pollution is a significant global issue in aquatic ecosystems, with low-micrometer plastics (LMMPs) posing particular risks owing to their small size and prevalence in various environments. The U.S. Geological Survey and collaborators are developing an innovative sensor to detect and analyze LMMPs in freshwater systems, achieving rapid and accurate results without the need for additional...
A National Predictive Model for PFAS Occurrence in Groundwater
In October of 2024, USGS Scientist’s published a study where they created a model to predict PFAS occurrence in groundwater at the depths of drinking water supplies. This model can help guide our partners to sample areas where PFAS in drinking water could be an issue for the public.

Per- and Polyfluoroalkyl Substance (PFAS) Core Technology Team
The Per- and Polyfluoroalkyl Substance (PFAS) Core Technology Team (CTT) within the Environmental Health Program partners with external and internal stakeholders to develop and apply analytical methods for measuring PFAS in complex matrices, addressing environmental health issues related to transport, distribution, fate, effects, and exposure.
Per- and Polyfluoroalkyl Substances (PFAS) found in Smallmouth Bass (Micropterus dolomieu) throughout the mid-Atlantic United States
Per- and polyfluoroalkyl substances (PFAS) are a large group of chemicals that have been recognized as concerns for both human and ecosystem health. There is a need to understand the effects of PFAS on fish health and populations.
U.S. Geological Survey Develops Per- and Polyfluoroalkyl Substances (PFAS) Sampling Guide
USGS scientist’s published a Per- and Polyfluoroalkyl Substances (PFAS) sampling guide for personnel involved with Natural Resource Damage Assessment and Restoration (NRDAR) activities. This guide introduces individuals involved in NRDAR efforts and other investigators to key concepts and considerations when sampling different environmental media for PFAS.
Human-Related Compounds in Water Sources in the Grand Canyon Help Identify Water Flow Pathways and Highlight Potential Water Quality Changes
U.S. Geological Survey (USGS) scientists investigated the movement of human-generated chemicals, such as pharmaceuticals and per- and polyfluorinated substances (PFAS), in groundwater along the South Rim of the Grand Canyon. This research led to a better understanding of the movement of wastewater into groundwater, of complex underground flow patterns, and of chemicals present in springs near...
USGS Scientists Develop an Interactive Mapping Tool to Visualize PFAS in Tap Water
A new interactive dashboard is available to visualize PFAS measurements for 716 tap water samples collected at select sites across the nation between 2016 and 2021 from private and public supplies.
Unique Approach to Measure Per- and Polyfluoroalkyl Substances Uptake in Fish, Mussels, and Passive Samplers
Per- and polyfluoroalkyl substances (PFAS) uptake and bioconcentration by fish and mussels ─ housed in mobile laboratories at a legacy fire-training area contaminated by aqueous film-forming foams ─ varied by species, sex, and compound. PFAS in passive samplers deployed at the same time mimicked uptake by fish but not mussels indicating that passive samplers might prove useful as screening tools...
Per- and Polyfluoroalkyl (PFAS) Measurements in Tampa Bay Fish and Sediments Provide an Understanding of Potential Human Exposure
Scientists provide an understanding of per- and polyfluoroalkyl substances (PFAS) levels in sediments and the edible portions of fish within Florida’s Tampa Bay in a pilot study designed to understand the potential for human exposure and health risks through fish consumption.
