PFAS Fate and Transport 2021 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.
As a groundwater professional, you may need to inform a customer of the potential for PFAS contamination in their well water and subsequent actions to mitigate exposure. NGWA recently published “PFAS Risk Communication for Contractors,” a two-page fact sheet to aid groundwater professionals in such communications. The document features common questions that may be asked and talking points that may be of assistance.
The document was crafted by the following volunteers and NGWA staff:
- Bill Alley, Ph.D., NGWA
- Melissa Harclerode, Ph.D., ENV, SP, CDM Smith Inc.
- Shalene Thomas, VP, Wood Environment & Infrastructure Solution
- Andy Horn, PG, Westwater Hydrology LLC
- Dave Schulenberg, NGWA.
and private wells
NGWA recently published “PFAS and Private Well Owners: What You Need to Know,”
a two-page fact sheet that groundwater professionals can distribute to customers and others in their community concerned about PFAS. Written in easy-to-understand language by groundwater professionals, it explains what PFAS are, how to test wells
for PFAS, treatment options, and more.
The document was crafted by the following volunteers:
- Jeff Hale, PG, Parsons Corp.
- Karen Kinsella, Ph.D., GZA GeoEnvironmental Inc.
- Jim LoCoco, CPG, Mount Sopris Instrument Co. Inc.
- Richard Mest, Master Water Conditioning Corp.
- Brandon Newman, ECT2.
NGWA published Groundwater and PFAS: State of Knowledge and Practice, a guidance document on PFAS in 2017. Created by 36 NGWA volunteers who spent 1100 hours on it over the
course of 12 months, it is a comprehensive eight-part piece exploring the potentially hazardous, and widely discussed, compounds in groundwater and soil. NGWA published the document to identify the known science and knowledge related to PFAS; it summarizes
the fate, transport, remediation, and treatment of PFAS, as well as current technologies, methods, and field procedures.
NGWA PFAS expert
Seth Kellogg, PG, a senior geologist at Geosyntec Consultants, was elected to the board of the Scientists and Engineers Section of NGWA in 2016, and the national board in 2019. She has more than 25 years of experience in evaluating
complex contaminant hydrogeology and groundwater/surface water interactions, including large groundwater and sediment sites in New York and New Jersey. As PFAS have emerged as environmental concerns, Kellogg has been working with NGWA to advance the
industry’s understanding and implementation of best practices. She has presented and published on the technical and regulatory challenges of PFAS contamination, including coauthoring NGWA’s Groundwater and PFAS: State of Knowledge and Practice (NGWA Press 2017). In May 2018, Kellogg was recommended by members of the NGWA Board of Directors to represent the Association at the U.S. Environmental Protection Agency National Leadership Summit on PFAS. Kellogg’s leadership on PFAS has also
included several presentations educating industry professionals on the fragmented PFAS regulatory framework, PFAS characterization challenges, and the complexities of PFAS fate and transport. She also served as a program adviser and facilitator for
NGWA’s PFAS in Groundwater Workshop that was held in August 2018.
