Groundwater and PFAS

PFAS, or per- and polyfluoroalkyl substances, is a category of human-made chemicals that have been widely used in a variety of products and industries, such as firefighting foams, protective coatings, and surfactant applications among many other uses and products. This website section provides information on PFAS particularly oriented toward private wells and the water well industry to help you understand the sources and occurrence of PFAS in groundwater. If you are concerned about the possibility of PFAS in your drinking water and are served by a private well, both NGWA and the U.S. Environmental Protection Agency recommend testing your drinking water as well as reaching out to your local health department for information.

As an authority on groundwater in the United States, NGWA is a leader in the science of PFAS affecting this important natural resource. Directed by a standing task group dedicated to advancing the knowledge of this emerging topic, NGWA’s PFAS initiatives include hosting PFAS conferences focused on groundwater and publishing multiple products (technical guidance documents, white papers, fact sheets, position papers) related to PFAS, groundwater, and the water well industry.

The last several years have seen a flurry of wide-ranging legislation concerning PFAS (per- and polyfluoroalkyl substances) from Capitol Hill and state legislatures. NGWA has been a key resource on not only providing the sound science to inform policymakers about these “forever chemicals,” but also providing solutions that our members’ expertise can provide to ensure our groundwater resources are safe and reliable. While we agree states have a right to manage and regulate PFAS based on their unique circumstances, we also feel the federal government must provide clearer and scientifically researched guidance on PFAS treatment and disposal.
