Monitoring the occurrence of per- and polyfluoroalkyl substances (PFAS) is important because of its long history of use in the United States and the unknown distribution of environmental releases over space and time. This application shows locations across Virginia and West Virginia where PFAS have been sampled by the U.S. Geological Survey's Virginia and West Virginia Water Science Center as part of ongoing monitoring efforts conducted in cooperation with local and regional partners. Partner agencies include the Virginia Department of Environmental Quality, West Virginia Department of Environmental Protection, the Virginia Department of Health, and the West Virginia Department of Health and Human Resources. These investigations span research on the distribution of PFAS contamination in surface water, groundwater, streambed sediments, and in the edible tissues of fish. These sample types are symbolized independently on the map. Click on a point to access site-specific information and a link to the source publication containing the measured data.
