PFAS has moved to the front burner according to the first speaker on the last day of NGWA’s PFAS Management, Mitigation, and Remediation Conference, June 20, in Westerville, Ohio.

The final day of the event, which featured more than 100 attendees, led off with the plenary session, “Contaminants and Compliance: The 30,000 Ft. Perspective” by Jeff Rose and Amy Dindal of Battelle.

Rose, the vice president of government affairs at Battelle, opened the talk by saying “PFAS has gone from not being on the radar to being on the back burner and is now going to the front burner.”

He then went over the legislative action on PFAS — per- and polyfluoroalkyl substances — taking place in Washington, D.C., as well as in state capitals. At the federal level, there have been 32 PFAS-related bills introduced so far in 2019 — after a total of 17 were introduced in the previous five Congresses.

Dindal, the PFAS program manager at Battelle, compared and contrasted PFAS to other federally regulated environmental contaminants and discussed some difficulties of PFAS remediation technologies, including large plume sizes, solutions being energy-intensive and costly, and the difficulty of chemistry breaking down the carbon-fluorine bond.

She concluded by saying, “We are on the front end of the journey, which is likely to be long. These unique chemicals are likely to require new thinking and new technology.”

Their presentation was followed by that of their colleague at Battelle, Ryan James, Ph.D., whose talk was titled “Regeneration of Granular Activated Carbon used for Polyfluorinated Substance (PFAS) Remediation.”

Granular activated carbon is commonly used for treatment of PFAS but cannot currently be regenerated without removal from a system. James went over tests at Battelle that have yielded data that shows there is a possibility for this to come to fruition, which would significantly reduce lifetime costs of treatment.

Another highlight was a panel titled “PFAS — the Water Supply Perspective” that included comments from Jennifer Gray, Ph.D., of the Michigan Department of Health and Human Services, David Harn of the State of Michigan-EGLE, Richard Head, J.D., of SL Environmental Law Group, and Roderick Dunn of the Water Quality Assurance Laboratory. The panel was moderated by Avram Frankel, PE, of Integral Consulting.

Discussed was how PFAS has quickly become the MTBE of this decade and most states are struggling to ensure safe, potable water supplies for their residents. The panelists offered perspectives from their experiences on potential paths to dealing with these challenges.

The two-day event began on June 19 and was highlighted by a keynote address from Robert “Rob” A. Bilott, J.D., a partner at Taft Stettinius & Hollister LLP, who brought the very first PFAS environmental exposure case to the forefront in 1999. Doing so resulted in the discovery and public disclosure of PFOA (perfluorooctanoic acid) in drinking water supplies for approximately 70,000 people in West Virginia and Ohio, and that discovery spurred national regulatory interest and investigation into PFAS.

PFAS has been on NGWA’s radar for several years and will remain a priority issue for the foreseeable future. The Association has created an online Groundwater and PFAS resource center, which includes PFAS FAQs, top 10 facts about PFAS, and a homeowner checklist, among other items. NGWA is also the publisher of the guidance document, Groundwater and PFAS: State of Knowledge and Practice.

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. 

NGWA continues to advocate for:

pp-pfas-the-truth-about-private-water-wells
  • Supporting a bipartisan solution that creates a maximum contaminant level — or MCL — for PFOA (perfluorooctanoic acid) and PFOS (perfluorooctanesulfonic acid) based on the best available science
  • Dedicating financial and technical resources to private well owners for testing and remediating PFAS
  • Properly funding PFAS programs and solutions to ensure our groundwater is safe and reliable
  • Advanced guidance from the EPA on the treatment and disposal of PFAS.

PFAS: The Truth About Water Wells position paper

NGWA published this position paper in 2022 that provides facts about PFAS and how water wells can still provide safe water because effective residential-scale PFAS treatment technologies are commercially available. It is ideal for sharing with local, state, and federal officials. Download the position paper.

Practical Guide for PFAS Sampling white paper

pfas-contractors

The NGWA white paper, Practical Guide for PFAS Sampling, provides a practical guide to PFAS sample collection for those familiar with industry-standard environmental field sampling practices.

Groundwater professionals may be called on to sample for PFAS analysis and to interpret PFAS laboratory data. The presence of PFAS in many products, potentially including products commonly used in environmental field sampling efforts, should be considered when planning a PFAS sampling program, and this document provides a guide for such programs.

PFAS Fate and Transport 2021 white paper

NGWA’s white paper, PFAS Fate and Transport 2021, 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.

PFAS risk communication

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. PFAS Risk Communication for Contractors is 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. 

PFAS and private well owners

PFAS and Private Well Owners: What You Need to Know is 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. 

NGWA guidance document

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.
