NGWA Publishes PFAS White Paper

NGWA recently published the white paper, PFAS Fate and Transport 2021, that updates section four of the NGWA guidance document, Groundwater and PFAS: State of Knowledge and Practice, which was published in 2017.

Since the release of that guidance document, many studies have investigated PFAS (per- and polyfluoroalkyl substances) transformation, partitioning, and transport—for example, the influence of PFAS accumulation at media interfaces, such as the air-water-solid interfaces in the vadose zone.

This white paper picks up where that section of the guidance document left off by providing important updates.

In the last year, NGWA has also published a document with talking points to aid professionals in discussing PFAS contamination with customers and a fact sheet about PFAS written in an easy-to-understand language that professionals can distribute to customers and others in their community.

All of these items and more can be found at, which is a complete resource center about the groundwater contaminants.
