Does the USGS have data on PFAS in drinking water?
Use the USGS PFAS in US Tapwater interactive Dashboard to find PFAS data for drinking water. Instructions are on the website or watch a short video about the dashboard.
The dashboard incorporates data from several USGS reports that cover PFAS in water sources, including community water supplies. Some notable studies and datasets that were used for the dashboard include:
- Per- and polyfluoroalkyl substances (PFAS) in United States tapwater: Comparison of underserved private-well and public-supply exposures and associated health implications
- Concentrations of per- and polyfluoroalkyl substances (PFAS) in tapwater collected throughout the United States, 2021-22
- PFAS Reconnaissance Landscape Data
Find additional reports on the USGS PFAS Integrated Science Team website under the Publications tab.

Assessing per- and polyfluoroalkyl substances (PFAS) in sediments and fishes in a large, urbanized estuary and the potential human health implications Assessing per- and polyfluoroalkyl substances (PFAS) in sediments and fishes in a large, urbanized estuary and the potential human health implications
The primary source of chronic exposures to per- and polyfluoroalkyl substances (PFASs) in humans is through the ingestion of contaminated foods and drinking water, with fish and other seafood being a major contributor. Nevertheless, there is scant literature on the dietary exposure to PFASs for the general United States (U.S.) population. The Tampa Bay (Florida, USA) region has the...

Concerns related to perfluoroalkyl and polyfluoroalkyl substances (PFAS) in sources of drinking water and in natural and engineered environments have captured national attention over the last few decades. This report provides an overview of the science gaps that exist in the fields of study related to PFAS that are relevant to the U.S. Geological Survey mission and identifies...

The U.S. Geological Survey (USGS) is working with Federal, State, and local partners to monitor and evaluate perfluoroalkyl and polyfluoroalkyl substances (PFAS) in the State’s groundwater and surface waters. PFAS are synthetic chemicals with widespread commercial and industrial use that can take a very long time to break down in the environment and may affect human health. The USGS in...
