Summary
Description PFAS-Tapwater DetectionMap 1.png |
English:
This USGS map shows the number of PFAS detected in tap water samples from select sites across the nation. The findings are based on a USGS study of samples taken between 2016 and 2021 from private and public supplies at 716 locations. The map does not represent the only locations in the U.S. with PFAS.
Most of the exposure was observed near urban areas and potential PFAS sources. This included the Great Plains, Great Lakes, Eastern Seaboard, and Central/Southern California regions. The study’s results are in line with previous research concluding that people in urban areas have a higher likelihood of PFAS exposure. USGS scientists estimate that the probability of PFAS not being observed in tap water is about 75% in rural areas and around 25% in urban areas. Learn more about USGS research on PFAS by reading the USGS strategy for the study of PFAS and visiting the PFAS Integrated Science Team’s website. The new study builds upon previous research by the USGS and partners regarding human-derived contaminants, including PFAS, in drinking water and PFAS in groundwater. |
