Hydrologic and Water Quality Studies of PFAS in Pennsylvania

Science Center Objects

USGS is working with Federal, state, and local partners to monitor and evaluate perfluoroalkyl and polyfluoroalkyl substances (PFAS) in the Pennsylvania'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 Pennsylvania Water Science Center is working with the Pennsylvania Department of Environmental Protection and experts across the Nation to develop and implement rigorous and innovative techniques to detect PFAS at concentrations as low as parts per trillion to help the public understand the spatial distribution and magnitude of PFAS contamination within the environment. PaWSC and the U.S. Navy have partnered to study the occurence and migration of groundwater containing PFAS from former naval facilities and other sources in southeastern Pennsylvania.
