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.

PFAS in West Virginia's Groundwater and Surface Water

In 2019, the West Virginia legislature recognized the contamination risk to public source-water supplies posed by per- and polyfluoroalkyl substances (PFAS) and passed a resolution that required a statewide PFAS study. The purpose of this resulting study was to understand the occurrence and distribution of PFAS contamination throughout the state’s rivers, lakes, and groundwater aquifers. This...
